- 2. As a technicallyminded and creative person I enjoy all aspects of product design, particularly the ability to work on a design from scratch and see it through to the final result. I enjoy both digital and physical modelling, and experimenting with different shapes and form to come up with the desired result.

- 4. For my finalyear project I am making a printer that produces braille and tactile diagrams. The goal of this project is to bridge the social gap between children with visual impairment and sighted children. Furthermore, teaching children about braille as they play together. Brint
- 5. Result Noise Quality Size Quantity The average noiselevel of Brint when printing is 55.3db, which is lower than 80db of existing braille embossers. Feedback from user testing shows that the braille produces on Brint is highly readable and the readability is greater than embossed braille. Older people with reduced sensitivity can also feel the dots. The size of the Brint is 100mm(Height) x 509mm(Width) x 411 (Depth) and has a greater footprint than a modern A4 ink-printer. Each cartridge contains 60ml of paint. Calculated from test results, each cartridge can print up to 200 pages of braille before it runs out of paint. Hence, each page of braille will only cost 0.8p to produce, whereas embosser paper will cost 7p per sheet (currently the cheapest method of producing Braille at home). 200
- 6. The design ethosis to produce a high quality product with minimal costs. Therefore, the product will be made to order and manufactured in house to maintain high quality control. The turnaround time is 3 weeks maximum from receiving the order to completing the assembly, this includes the shipping of components, 3D printing and laser cutting. Other factors such as delivery distance and number of orders will increase the delivery time. Production Plotter mechanism in the printer controls the X-axis and Y-axis and is driven by 2 stepper motors. The servo raise and lower the nozzle to control the deposition of the paint. Brint is designed for low volume production. 3D printing is an ideal process for producing complicated mechanical components of this scale of production.

Testing “For a printer that can do this £800 sounds alright to me and it uses standard paper and acrylic from the shop which is great! You can only get braille paper online, but for this you can just go out and buy some.” - Dave
- 9. The aim wasto design an easy clean potato masher to be taken to Kickstarter for crowd funding. The project was a means of marketing for Mind Sketch. The potato masher is intended to be playful and have a friendly appearance, encouraging the user to display it when not in use. Puray Placement project - Potato masher
- 10. Removable handle madeof nylon for scooping the mashed potato. Features This project was very different to any other projects I completed in the past because it included crowd funding and marketing which I had never came across before. Role- I was the lead designer of this project, whilst my manager provided guidance on the development. Additionally, I was also in charge of the marketing. 3D-printed prototype • Design for manufacturing (Injection moulding, zinc casting) • Understanding and choosing food grade materials • Online Marketing • Product/prototype testing Skills

- 14. Tolerance issues suchas material thickness, component alignment and edge profiles were troublesome but are able to be overcome with practical skills such as wood working. Construction Role- I was the lead designer on this project, responsible for the designing, developing and making of the dispenser. Layout of the electronic components.Cardboard prototype of the dispensing unit. Final dispensing unit made using a laser-cutter. Mechanism Prototype. Final mechanism design. • Mechanical design and engineering • Physical computing - Arduino • Tolerance control • Model making - wood working Skills
- 15. As a teamof 5 we had to design a product for Robot Bike Co. The product or the technology used has to be viable within 3-5 years time The goal of the brief is to expand their current market and get media coverage in order for more people to know about their bespoke mountain-bike frame tailored to the user. Optim Live project - Robot Bike Co • Customised saddle • Promotion booklet • Hex key • Optimised coaster (3D-printed)
- 16. The data capturedby the pressure sensors will be used to optimise the foam structure in the saddle (red). The foam structure will be made using 3D printed polyurethane. Bespoke 1The user take the a ride with a pressure-sensitive saddle. 3The user pick their favourite leather design and colour. 2Process the data and optimise the saddle’s foam structure 4Manufacture the saddle. 5Deliver the custom saddle to the client. “A poorly fitting bike saddle can cause pain which, at best, is uncomfortable, and at worst, could have long term effect, both on and off the bike.”
- 17. The pattern isa decal applied to the leather. The user can choose to have their name or logo printed instead. Customisation Visualisation of the pressure distribution on the pressure-sensitive saddle. The electronics Pressure-sensitive saddle prototype: using Arduino to capturing data from the pressure sensors and visualising it on Processing. The user can pick their favourite colour for the leather of their saddle.
- 18. Within a numberof weeks time we are expected to learn to use Grasshopper 3D (plug-in for Rhinoceros 5). Our brief was to use generative design to create a family of elegant test tube vases together. As a team, we decided on setting the test tube at a 15° angle from vertical as a challenge.

Create loft profile LoftArray; Project cure Join mesh Create mesh; Smoothing Shift points; 3 point arc; Interpolate Loft; 3D population; 3D voronoi Changing the parameters in the grasshopper definition result in a different outcome. Users can customise the model based on their individual preference. FDM 3D-printing is destined for producing the prototype model, therefore, a number of requirements have to be met during the design process. • Generative design - Grasshopper 3D • Identifying design and manufacturing constraints • Designed for 3D-printing, without the need of support material Click the following link to view and modify the model: http://beta.speckle.xyz/view/s/Vyp Design space Skills
- 21. Following the “Test-tubeVase” project, we then tried to apply generative design to products for mass manufacturing. The goal of this project was to create a plant pot that grows with the plant. The target market was aimed at both plant retailers and their customers who wish to purchase an affordable, innovative and attractive design. Crease Generative design - Origami plant pot Origami is one of my hobbies. I sometimes find it challenging to learn and often need practice to become adept. However, it is very rewarding and fulfilling to finally see the outcome.
- 22. Explore further intothe retailing aspect of this project, I discover that the Hexagonal profile consume less space than square, triangle or circular (current design) which benefits both retail and transportation. Existing plant pots are often cumbersome and awkward to store of shelve because of their shape. Shelving layout 1Pre-expanded plant pot. 3The plant pot expanded under compression.2User apply forces onto the plant pot. • Implement origami into product design and packaging design. • Efficient shelving and transporting arrangement. • Expandable design reduces the need of re-potting. Achievements
- 23. Unfold the origamidesign into a flat sheet using Grasshopper 3D to prepare for prototyping and manufacturing. Use rotary-die-cutter to cutting and create score lines on the Polypropylene sheets. The corner sections (highlighted green) are joined together using adhesive. This process is commonly used in the packaging industry along with folding sheet material. Manufacturing Create main folding mesh (1 fold each) Create profile Expand the origami mesh Create corner folding mesh (3 folds each) Create bottom folding meshes (12 folds) Fold the bottom mesh Combine the meshes together The cut polypropylene sheets can be flat pack and stack ready for distribution. Large quantities can be stored and shipped efficiently. Generative design is not only able to simplify and accelerate the design process, but also simulates the folds, to show dynamic movement.
