A2 dt development stage smaller 2

  1. 1. Initial Design Concepts Alastair Cross KEF InspiredMonday, 19 November 12
  2. 2. Development Aesthetics- squaring up Aesthetics- The Shard From the start i always wanted my design to be inspired somewhat by architecture and the shapes that are created in the real world, while the initial ‘squaring up’of the design has helped improved my vision of what my design would be like, i would want to also used a certain case study to almost When i use as a direct link to another aesthetic change. The shard, first which is near complete in London has always interested me looked at my due to its pyramidal shape and stunning angles it can design that i be seen from, and as this is what i want my plan on creating, and more importantly the aesthetics of design to be like, i plan to use some shapes the design, i saw the idea as a very soft and visual aspects of the shard to help my style with the use of all the smooth design. The first part of this structure that curves and the general roundness interests me would be the tip of the of the design. From here however i shard(left). I have taken construction images did say in my initial specification it and zoomed closer to see the detail and would stand out in a modernism clearly from the images there is the steel top room, and Im not sure the level that it which gives a very blade like feature and is at is striking enough to the eye. So gives a certain danger to the design, i will clearly i had to change something. So probably use this feature however the what i did was to start sharpening and construction methods will have to fit in for me edging of my design to, almost make my to incorporate this. Secondly is the open design more viscous to the eye. I started space between the struts in the building itself, with a side profile of the design and added now views and details to give using this on my design me an idea of what i was working would give it a raw and towards, and clearly from the almost unfinished edge just results(left) the design is like a sculpture would have certainly more striking with and this could be done with not one curved edge the the use of a clear and pointed edges as material three separate locations. From what i have changed from the design i feel it has improved it, not only to follow my specification more throughly but it also looks much more attractive, and this is what i wanted to achieve. Alastair Cross KEF InspiredMonday, 19 November 12
  3. 3. Development Construction- Initial Structure Construction- Bolts and Screws Moving on from the previous idea of the initial Before i went any further into structure, rather that the my development i wanted to use of adhesives all over my get my initial structure or the design which would be mostly skeleton of my design completed weak and a long process, i so once the basics are done i can would prefer to use bolts and focus on more of the details and screws to create a more parts that will permeant joint to al the main characterise components of the design. my design. There are many different types From the of bolts i can use, for example a left, my dome head bolt which would suit design will well with my design as it would give have a different dimension and a straight different texture which may make edges all my design more interesting if people over the design, were to look closer at the more this should help with joining processes detailed parts. From the top right and also making it more sturdy and so image, and the top right of the the longevity can be extended. Another picture the idea point that i will make would be the idea of of a 90 degree balance of the whole weight is to be put steel joint which on a section of the wall, this means my would make design will either have to have a very complex strong wall joint or have a relatively angles light weight with all the materials strongly added together so that it will not fixed to fall of the wall at any point. But the due to my idea of the shard and design different materials i want to incorporate my wall design will have to be strong instead. Alastair Cross KEF InspiredMonday, 19 November 12
  4. 4. Development Construction- Adhesives Construction- Wall Joint Although i did say adhesives were a longer and weaker Here i have created wall joint process to joining larger sections of my design together it prototype to where i will be able to doesnt mean that the smaller place my design over, it may be parts cant be joined using using the simple but this means i can make it different methods on the left. incredibly strong from strong Adhesives such as cement, epoxy materials. To begin with i used one resin, PVA and glue gun glue sticks sheet of a bendable material, here i can all be used differently on different materials to ensure the bet used thick cardboard as it can be stick, i will most probably use all of easily bent and shaped. Then cut these to give my design the best diagonals on the corners and then overall quality. Glue gun glue sticks fold them over, if this process it are very versatile joined strongly, this means my design and can used on can be slotted into the wall joint and most materials can be permanent or however it may not temporary depending on be strong enough preferences. However it needs to hold non porous to be strong so i will make it in materials. The sections and join them together strongest adhesive using strong joins like a dove would be cement tail. This will improve the however this longevity. would severely weigh down the design and so i will have to look for different adhesive later on. Alastair Cross KEF InspiredMonday, 19 November 12
  5. 5. Development Construction- Model Usability- Card Model Next was a more solid model Continuing on from the giving me a better understanding development of of how someone may use my construction i wanted to design and how i might change look more in detail about some aspects of the design so how my design will hold that people can find it more together when it is being natural to find and use some of build, and although this the attachments that may be model is only a 2D added. To begin with, image top, representation using this gives a perspective of how lightweight wood sticks, it someone may see my gave me an idea where the design(walking down stairs) and stressful parts of the design from this view i could clearly see are and where the key point an opportunity to add the are if it was to break at any controls to may design while not point. A key area of this spoiling the aesthetics, or even model was the parts joining adding to the aesthetics. Using the two curved segments of the image on the the design up, it was fairly left we can see i flexible even when i had have added small glued it down meaning this is markings on the the part where more card to show some industrial joints or adhesives places where were to be applied. Another buttons can be section would be the top of placed, this gives a the lower curve, this was greater usability of also quite delicate but the product as from here i know that a they dont have to strut would go from he walk directly in tip down through front of the the design so this speaker to change would not be volume, song etc... a problem. and so the sound of the speakers will not be distorted by someone standing in front of the speaker Alastair Cross KEF InspiredMonday, 19 November 12
  6. 6. Development Usability- Ergonomics Usability- Anthropometrics Ergonomics are a key point in any design that has been carefully been planned out to work Now anthropometrics focus on the sizes of around a human, my design is no different as i the human body rather than making a product must take account of the different sizes to allow fit around a human, i have already looked at the my user to use height of someone in my design ergonomics comfortably and and how they with ease. As my must be able design is wall to use the mounted i will design but have to take here i plan to some change my measurements to design so than see how my everything is design will be natural, one placed(height quick on wall). An example will average sized be the man is around measure of 5,10 ft tall and a woman 5, 5 ft tall, this means my someones design will have to be around 6 ft of the ground arm and then use this information so that the so that it is not in the way and keeps itself design is no wider than this (0.8 metres), this spaciously efficient but also so that all would improve my design as it would allow people can reach the design and change people to reach around and make it certain aspects without issues or more accessible from different angles problems so that my market does so that it is not constantly in the way . close up on the taller/shorter Alastair Cross KEF InspiredMonday, 19 November 12
  7. 7. Development Usability- Card model con. Usability- Placing of Speaker Again i am going to look at card model however this time i have zoomed in more to see how someone may approach, now for the bottom image the place where the controls may go shows there is only room for around 6 buttons, that gives enough for on/off, volume and track change which is perfect, however on the other side i plan to put on additions for the movement or removal of the speaker just to allow easier Placing my speaker in a suitable location in a typical accessibility modern home is very important to what i am trying to achieve in the development, as i would like my design to be aesthetically enjoyed from most areas in the room and also from the sound to be heard and finally for it to be specially efficient. On the is simple CAD(computer aided design) image of a typical room i have put on green circled areas in and around the room which would be effective for all three of the criteria however the red areas are places where they do not fit either one to none. Although every home is different it still will always have a key vocal point in a room which anyone can exploit. This a key part that i will use and always relate back to as this will ensure that my design is core to a room Alastair Cross KEF InspiredMonday, 19 November 12
  8. 8. Development Materials- Carbon Fibre Materials- Clay Another material that i wanted to experiment with was clay, although it may be a rather unorthodox material for such Like i have said before leading designs for speakers etc, up to my development, i have the shapes and always planned to use carbon textures that fibre in my design as it is a very can be created would stylish, modern material. And from give my design the left i have tried out over some something basic moulds to see how it works. special about it, but this all Carbon fibre is done in layers with depends on releasing agents being applied how practice went. On the first to the mould then we apply left we have around two layers of carbon some images weave with hardener, all one at a of a test run on the whole time after allowing to dry. model, and the Although the process may be mess was terrible with all simple, to do well it is very difficult of my mould this is why it was good for me to covered in practice with different things dried clay and was fairly before i am to start make it fully. awkward to From this i will only use carbon get off. After fibre on a small part of my using clay i feel it is quite a design, so that room for error is rough edgy low and so it can be done material that probably will well and to a high standard. not fit my To use this i may apply this design as it material to the tip of the must take time, design giving it a patients and shine and lots of resources to sharpness. make clay attractive to the eye. Alastair Cross KEF InspiredMonday, 19 November 12
  9. 9. Development Materials- Steel Rods Materials- Polishing Plaster I have never thought of using plaster before as for most Using steel pure can be tricky however using steel rods for times the quality of a design can be generally very easy and also look good if finishing is not the finishing of the material is done to a high standard. With this test i have got three lines of steel rod. The first one is good enough for rough with no finishing it is nice designs, ugly and very dirty to the however after eye. The second has been seeing what sanded with course sand polished plaster paper to technically give looks like when the rod a ‘grain’ which done well it looks looks very edgy but also like something quite clean. And finally the that would work bottom two images have with my design. had a full finish done in For polishing them which the use of plaster it is very smaller grain sand paper simple all that followed by wet and dry needs to be done then moving onto buffering and then finally polishing. is: sanding a steel Now this last process takes trowel this removes and long times and does imperfections, give a good shine to the wiping trowel with steel rod, however it does tack cloth then just remind me of the KEF rubbing in short Muon which is very strokes with polish, clean and wipe wall then wax sophisticated, on the the wall. This process other hand i would is very simple and like my design to be yet we can see from a little shaper so i the images the finish will go with the looks good on all middle method different surfaces of steel finishing however this is not regular to use on product especially speakers so i will have to see what happens later in manufacture. Alastair Cross KEF InspiredMonday, 19 November 12
  10. 10. Development Materials- Wire Materials- Aluminium sheet I have used wire before and is excellent for Aluminium sheet can be worked on in many ways finishing of designs giving it and extra but the most interesting method for shine on a corner for me is cold giving a plain forging with a material some hammer, this texture, it is used in can give different parts of extraordinary architecture shapes in the especially bridges metal and can making it perfectly also be suited to my moulded design, i will use around rough wire however in shapes to small moderation create delicate and only for textures like for finishing touches example to the bottom left. I will try and use aluminium in my design where possible as it gives shine and it finishes well. Alastair Cross KEF InspiredMonday, 19 November 12
  11. 11. Development Materials- Clear/ Matt Acrylic Materials- Rubber I would like to use Earlier in my development i an elastomer in my discussed the design as it would influence of the give a bit of variety shard on my design as most of the and the the materials i will use raw nature of are very cold and the open un textured, structure however if i was to use an elastomer for interests me, the buttons for the well here in base of my product materials Ive it would definitely looked at the show more of a use of either quality in terms of a completely material that other clear acrylic, manufacturers glossy acrylic or of speakers like Bose, KEF and lightly transparent Sony use all the acrylic. From here i time. Touch have placed all these sensitive can materials up against also be added light, dark, wood, if available. plastic backgrounds to see which would suit best, now at the moment i will not be able to make my choice till i see the structure later in my development however the clearly acrylic seems to look good in all conditions. Alastair Cross KEF InspiredMonday, 19 November 12
  12. 12. Specification Check Aesthetics When designing my speaker the aesthetics will be modern and fit the profile of KEF, it will be smooth and incorporate different Here i have met the specification due to the research in materials giving it texture and character in the environment where it must be placed. I will use some composite materials in the sculptured and modern industry for example the my design, it should show and emphasise sculptured design as shard and geometric shapes. well as a modern minimalist feel. Cost My design will be a medium to high priced design, with the joining, materials and overall quality being good. The finishes While looking at materials such as carbon fibre and steel, should be extremely high and a smooth texture should be consistent throughout the product. It should be attractive to KEF this has gone along with this section costumers. Costumer The main users of my product (continued on page 11) will be a sophisticated character, male or female, very interested in functional artistic art and can be placed anywhere in their Due to the research in clay, ergonomics and specified environment. My user can be of any range as long as anthropometrics, this has been met the interest of music and art is apparent, and can afford the highly priced product. Environment My design will be placed in a very minimalist and modern home environment which can be distinguished wherever it is placed in that environment. I will be placing my design to conserve most When i had looked at the environment to see where my space in an environment either on a wall, ceiling or shelfs. It design will go, i have fulfilled this section should stand out but not to the scale where the design look ridiculous. Size In terms of the product, the design can be any type of size due to the amount of free space in the modernist environment, however i do not plan for my design to be as big as a design as In ergonomics i have looked at how a human will fit the KEF Muon. It is to be big enough to capacitate the speakers around certain sizes, this has been met and be recognised in the environment as a stylish piece of gear, that is the only specification for size. Safety For my design there will be minimal issues with the safety as it will be placed in an area which should not be in the way of the Due to the research on the wall joint, the product should user. As before my design should look as if the design becomes one with the environment, and look aesthetically pleasing while be safe and will not cause health issues doing so Function There can be many functions and features for speakers however my design should be mainly aesthetically pleasing and I have looked at aesthetics in detail and the development functional in terms of the sound that will be produced. I may onto elastomers is key in meeting this section include some small smart features such as touch sensitive, but nothing to change the style of the design. Materials I have used an abundance in materials like carbon fibre etc... I will use materials mostly including plastics and wood, however However , i have not looked at the use of wood yet which is to make my design unique i might use some smart materials something i will have to look at such as carbon fibre.... Alastair Cross KEF InspiredMonday, 19 November 12
  13. 13. Development Section 2 Materials- Finishing Off Materials When i finally start to create my speaker design, the finish of the materials that i am using, such as steel, wood and carbon fibre all have a certain look and texture when i use them, however as my design will be a sculpture style i want my design to be finished off to the highest degree. For wood (pictured right), i experimented with the use of wet and dry and varnish. With wet and dry it gives the wood a certain crisp-ness to the wood making it sharper and more defined, however the wood pictured far right i have added a varnish, this makes the wood a more complete colour and more consistent. From this i will only use wet and dry as it resembles sculptures to a higher degree. With metals such as steel only finishes such as wet and dry, buffing and polishing are available to me. However as before in my development i have looked at this therefore i will only use wet and dry as it gives the material an edginess. And finally the use of plastics, now all acrylic sheets come pre-finished and so not much can be done. I will however sand the edges and clean the acrylic with window cleaner to maximise its finish. Materials- Joining As my design will be using so many materials and process i decided to look at joining all of these different materials together..... Woods Plastics When connecting woods to plastics, the main type of permanent joining would be bolts and screws with the availability of adhesives and other types of joints(dove tail). On these two materials slight flaws such as scratches or marks are a big problem as they would show heavily. So because of this i will use carefully the use of adhesives such as epoxy resin, and if done correctly will look clean and be strong. Woods Metals For woods and metals, a very efficient and strong method is the use of screws and bolts to hold these two together. After practicing with the use of bolts it seems the only valid and strong option as much of the strong parts of my design will be made of these two. It will also give me a chance to use the new finishes and using them together from the development above Plastics Metals And finally for the last two different materials, now plastics and metals are rarely used together due to their contrasting styles of construction, however such joining as sheet-metal nuts or rivets are a valid option rather than adhesives again, such joining as wielding would not work, so from here i will be using these two methods Alastair Cross KEF InspiredMonday, 19 November 12
  14. 14. Development Section 2 Construction- Sized Model For practicing, viewing and changing the actual size of my design this will help me understand more about my design and will allow me to make mistakes in this product rather than my actual product. From Doing this sized model i have realised that the angles of the design and the corners are very important so later in my development i will have to look at this in more detail. Another point i will have to change will be the idea that it would be in three parts (page 36), but from now it will only be in two main sections with the top and bottom sections. This will help reduce the error i could make in measurements and make it easier to join one the parts are made. Construction- speaker placement/ Arrangement At this stage i will need to look at where speakers will be placed on my design to allow maximum effectiveness. Since my original idea was to include 3 sets of two speakers placed on the area to the left, this my have to be reduced as the size of my design will be be big enough to old all of them, from this point i have placed new rings of colour orange to tell where they will be placed. This allows all speakers to be seen and also allow the sound to travel in all sorts of different directions to be heard all over the room Alastair Cross KEF InspiredMonday, 19 November 12
  15. 15. Development Section 2 Construction- Wire Placement As my designs main focus is to be as aesthetically pleasing as possible the idea of wires must strongly be considered. Even if my design turns out to be battery powered there is still connector wires that will be a possible problem. From this i have identified on the far right where the initial wire will come from the speaker, then on the immediate right shows where the wire will trace on a smaller scale and clearly shown on the left is the direct route it will take. From practicing this route it will able me to hide the possible viewing point and so keep it looking well finished and clean. Construction- Inside View Construction Due to the fact my product will have some open sections where someone will be able to look inside it, i must consider the way it is laid and and how well it must be finished. After looking a various sculptures inside and out, i noticed that from all views it does have an artist point to it, and i must incorporate this too, as this is the case i will have to finnish both sides of my design and to put materials must as metals and woods to complete and fill out the design. This has changed from my original idea and so a lot more time would have to be spent on this aspect. Alastair Cross KEF InspiredMonday, 19 November 12
  16. 16. Development Section 2 Construction- The joint of the sections From the multiple images of my design, there are clearly two main sections to the design, however there is also the joint to the wall mount which must also be considered. The idea of the sections would make it easier for me to create the design and join it together in sections. Looking at the two largest sections, as they will be made of steel rods of some kind a clear strong wield would be done to solidify this joint and make it permanent rather than the use of bolts and screws. The use of tungsten gas wielding would allow there to be a solid joint all along the two sections where they meet, this would able me to make both sections separately and join them at the last stage, saving time on working around them. Manufacture- Joining design (Basics) From the beginning from a purely one sided view of one panel of my design that there is a lot or room to attach and join parts of my design together, and over the manufacture i will be going into more detail. So from the basics of joining my design this is the lower section split up, and here i looked at the gaps where the struts of material would leave space and from a sculpture point of view this gives me a lot of choices with what i want to do with this space, but as i have already looked at architecture in the shard i must keep this open to follow my other research. But for this part of my research i plan to keep my design simple with minimal amounts of struts to keep joining to a minimum and also to follow my modernism design movement. Alastair Cross KEF InspiredMonday, 19 November 12
  17. 17. Development Section 2 Manufacture- Different order of Constructions Obviously the order i create my design will be very important as the whole design will be fairly heavy with all the steel and will need to be constructed slowly and carefully so that everything will be balanced rather than before where i thought i could create it all at once. To begin with i will create my sturdy wall joint, followed by the lower section, this will allow me to judge what the weight will be like, then the etc.... top section followed all all the smaller components of the design like the speaker switch etc... Manufacture- Template/ outline of design For my design i needed a template for my design where i can follow various parts of my design without making a mistake (such sections as general shapes, amounts of edges, width, general sizes, speaker placement, wire placement and also how the design will be pieced together. Also on this cardboard and MDF model i have circled in red where the major stress point will be and this is where extra care will be taken in terms of the joining processes and the materials finishings if there are any. Although i have used a thermoset glue, it has helped me practice and understand the problems i will have with wielding the design such as the tighter angles and the areas where there is minimal surface area and i will have to be more though rough with the joining. Alastair Cross KEF InspiredMonday, 19 November 12
  18. 18. Development Section 2 Manufacture- Ways of constructing wall mount There are many ways in which i can construct my wall mount which will be attaching to my design making it a wall mounted product. I can use more modern and traditional methods of wall mounting with images bottom right, they use finely tuned materials to be able to hold as much weight in as little space as possible, however i have already created one prototype in my development which has already worked well so i plan to use this design, although i have changed one small thing to give my design just a little more stability, it is a small V shaped piece of material screwed into the wall piece and then a diamond shape on the speaker side, rather than just laying all of its weight on the bottom of the wall joint, i have also looked at the idea of a twisting wall mount however this would cause problems from how rectangular the back of the design is, so i will not be using that idea.

Development Section 2 Manufacture- Ways i could make the frame/ structure On this page, as my design will basically be a frame sculpture i have looked at different types of framed structures, buildings etc... and from all off the types of frames they are incredibly well balanced and strong at every point, i have looked at weaker parts of my design already but now it is just the balance that i need to focus on, to achieve this the top section of my design my have a less mass to reduce pressure on the bottom section, this would keep the centre of mass lower and the overall weight of the design would be severely decreased. I have also been looking at the image and framework above of a wooden home and from research i have found that there are 10 main strong beams/ columns of wood holding the structure up with the smaller beams giving stability and shape, i would like to use this idea but i would use more like two or 3 main struts to hold the design up and the rest to give it its shape.

  20. 20. Development Section 2 Manufacture- Ways i could make Base (wall to main body) Joint For my design i did want a midpoint between the wall mounter and the actual design itself, and even since my design will not be going on the floor i have created a base. For this section coloured orange on the sketch to the right it would act simply to hold the main design all together. The elastomer that i plan to place in this position wouldnt need much thought in terms of joining as firstly it wouldnt be seem plus rummer is an extremely good material to be bolted which could work with all different types of materials. It would also give a certain amount of texture and class to the design when being touched or being looked at. Another thing i have thought about is the idea when it is not attached to the wall it must be laid down on the floor, however to make sure that the design can be picked up and can rest on the floor i will plan for the last bottom part highlighted green will be slightly longer and heavier so that the situation named above can be sorted, this would also help the usability of the design.

  21. 21. Development Section 2 Manufacture- Creating sharp clean edges A final Manufacture that i would like to look at with my design would be the idea of sharpening the metal on my design with the use of files, sanding and buffing to make it, not just to make it look better but also when Im joining this material it becomes a lot easier to join and makes the joint even stronger. Practicing this on aluminium it also works, this also makes the design have more emotion and feeling to it. This could be linked back to different materials i have used and how i have also finished them to be much sharper, and the way the design is going this will also contribute to it.

  22. 22. Specification Check Aesthetics When designing my speaker the aesthetics will be modern and fit the profile of KEF, it will be smooth and incorporate different My design has looked at making my design sharper going materials giving it texture and character in the environment where it must be placed. I will use some composite materials in against my further spec. however i have used a variety of my design, it should show and emphasise sculptured design as materials and plan to use them also. well as a modern minimalist feel. Cost My design will be a medium to high priced design, with the joining, materials and overall quality being good. The finishes With the processes and materials i plan to use the cost should be extremely high and a smooth texture should be consistent throughout the product. It should be attractive to KEF will be high costumers. Costumer The main users of my product (continued on page 11) will be a sophisticated character, male or female, very interested in functional artistic art and can be placed anywhere in their From images and development my design looks like a specified environment. My user can be of any range as long as modern speaker which sound be liked by my costumer the interest of music and art is apparent, and can afford the highly priced product. Environment My design will be placed in a very minimalist and modern home environment which can be distinguished wherever it is placed in that environment. I will be placing my design to conserve most i have looked a lot about where it will be placed and it space in an environment either on a wall, ceiling or shelfs. It satisfies this section should stand out but not to the scale where the design look ridiculous. Size In terms of the product, the design can be any type of size due to the amount of free space in the modernist environment, however i do not plan for my design to be as big as a design as i have done this by doing a sized model and and looking the KEF Muon. It is to be big enough to capacitate the speakers briefly at sizes and be recognised in the environment as a stylish piece of gear, that is the only specification for size. Safety For my design there will be minimal issues with the safety as it will be placed in an area which should not be in the way of the my design i out of the way however it is very sharp and user. As before my design should look as if the design becomes one with the environment, and look aesthetically pleasing while could hurt someone if it it too low down the wall doing so Function There can be many functions and features for speakers however my design should be mainly aesthetically pleasing and the function will be its wall feature and being able to see functional in terms of the sound that will be produced. I may inside the design, it fulfils the criteria here include some small smart features such as touch sensitive, but nothing to change the style of the design. Materials I will use materials mostly including plastics and wood, however i have used steel, aluminium, woods, plastic etc although to make my design unique i might use some smart materials not carbon fibre on a working model such as carbon fibre....

  23. 23. Development Section 3 Components- Parts in Wall Joint When looking at the wall design in terms of the components that i will use to create this section, i wanted to break up this part and see how the design well be pieced together. For this part it is very simple with splitting the design up into 4 simple sections and joined into two when the small parts on the top of the images are placed into the design. This gives my design simplicity which in term will make it easier to create and so able to be made in a higher quality. For the section to the bottom right it is one component however it will formed or moulded making it stronger in the longer term and also a better finish with no seams etc... Components- Wire conclusion As before i have looked and developed the direction of all the wires, i now have though of a final point on the design to place this holder for an iPod/ mp3 player, this would be placed on the underside of the bottom part of the design so that it does not effect the style of the speaker but also not the clutter the rest of the design with unnecessary parts and components. The components of this holder will be made from sheet aluminium to fit in with my design, this will keep that aesthetics consistent and clean. Alastair Cross KEF InspiredMonday, 19 November 12
  24. 24. Development Section 3 Components- Panels For this component i am looking at i want to look at the panel and how it may be seen and joined. To begin with from the sketch to left my plan is to place a panel of some sort of sheet material to cover some of my design, this my be acrylic or sheet metal. However were i want to focus on joining this section together- i can join this together with the use of adhesives but that will be messy- so instead i plan to pop rivet or drill which would work on steel rods well. Components- Measurements*(mm) 100 For this development rather than 250 150 200 looking at one individual component of my 50 design i wanted to look as them as a whole unit in 100 200 a working format. From here i looked at the specific 700 250 measurements to make my design work properly in a real life situation. Clearly From the diagram to the left 100 i have left out measurements for the inside construction, partly due to the fact it is hard to 45 measure this distance but also as the inside is not 350 110 as important as for the measurements as it only 300 must have a strong core and not necessarily a 250 particular pattern to follow. 300 Alastair Cross KEF InspiredMonday, 19 November 12
  25. 25. Development Section 3 Components- Angles to product Total 360 For my design to work and to be joined perfectly i have looked at the angles of my design so that it can look sleek and modern but also to be stable to hold its own weight once it has been built full and to its maximum mass with all the components and this will only happen with this development. For my angles i have given most strength through the use A of angles with the green circled area, as this would be the section where most of the weight would be forced on and the lowest angle C difference is the best. When looking at joining my product in more detail i have looked at compound joints where i will have to look B at what angles i will have to make the two pieces of metal so that they join together to make the total angle (images right). I have measured and calculated *C, however to create this angle i 360-A-B=C have to cut the angles into the two materials first, i can use the equation to the right to do this accurately for all my angles Components- The switches i will use and how they will be used For these components i have tried switches 1 and 4, and looked at the others 2 and 3- and from looking at what would look best on my design and would complement my style the most, numbers 1 and 2 would fit 1 2 with the materials of steel rods and sheets- and as before i have said how the switches will be lined up vertically along the side of my design i plan to change this so that they group the design in 2’s allowing easier accessibility and putting these components into the design. One this i have noticed is the use of joining switches to my design which would be done now with all the switches on one panel which would be then laid into the side of the design blending it into the 3 4 design and making it easier to work with.

  26. 26. Development Section 3 Components- speaker This is the design of speaker i will be using for my design as it uses the right colour scheme and it is the correct size to fit into my design also- For this component it has a diameter in length of around 90 and a diameter of depth of around 40mm, this size now gives my an idea of the sizes to cut out for the panels they will fit into, however i must watch out at the design is curved and the hole will have to be inch perfect. I will have to use a precise type of equipment to measure the diameter so that i can cut the correct size of hole. Components- Mid joint to the main design At this point i am looking in more detail in the mid section of my design where the wall joint will be joined onto the main design structure- and so this part has to be as strong as possible! to do this i plan to create a dove-tail joint which is incredibly strong and then covering it on an elastomer to fulfil one of my previous criteria. Using this sort of method just makes the whole process a lot simpler once the components are created. It is also a more professional method of joining. Alastair Cross KEF InspiredMonday, 19 November 12
  27. 27. Development Section 3 Components- Frame My final two pieces of Development come from the main feature of my design which is the frame and i wanted to use this last as the rest of my development can work around this main already rather than working the other way round. For the frame i could use squared rectangular or circular types of steel rod however the decision will always be made on how easy it will be to make the shape of my design and the ability to join the product up in a physically strong way. And from the clear example on the right the use of square hollow tubing is the best and the edges can be lined up but also can cut to fit into shapes and the shape of my design Components- Frame continued At my final stage i have used 3 different types of joining methods to see what is best for this component- The first using MIG wielding(top of triangle), this was a relatively quick process but left large bulks of material and often was difficult to clean up. The second technique(left of triangle and right) we have used a braising to joining the components and this was the quickest to join but also the quickest to sand down after. And finally to the right of the triangle using an acetylene torch to melt the material together, however this blew a hole into the steel which is a risk MIG i’m not going to take. In conclusion i will be using the brazing rod as it is the easier and quickest for of joining. BRAZING *PRACTICE Alastair Cross KEF InspiredMonday, 19 November 12
  28. 28. Specification Check Aesthetics When designing my speaker the aesthetics will be modern and fit the profile of KEF, it will be smooth and incorporate different I have kept aesthetics constant throughout by looking at materials giving it texture and character in the environment where it must be placed.

Costumer The main users of my product (continued on page 11) will be a sophisticated character, male or female, very interested in functional artistic art and can be placed anywhere in their My costumer will be into sculptures, and from the specified environment. My user can be of any range as long as components i have added, it still looks like a sculpture. the interest of music and art is apparent, and can afford the highly priced product. Environment My design will be placed in a very minimalist and modern home environment which can be distinguished wherever it is placed in My design has not changed where it will be placed nor that environment.
