2. Summary
Hi, my name is Callam and I’m a product designer! During my time at university I have
matured as an individual and evolved as a designer. I would like to work with a company
that can continue to help me take steps forward both as a person and in the design world.
In this portfolio you will see a collection of different work, demonstrating the various skills and techniques
I possess. This will include observation sketching, ideation sketching, modelling, 3D CAD work with
both Rhino and Solidworks, using both in conjunction with Photoshop to provide high quality renders.
As well as my skills, I have also included some key projects which taught me invaluable
information for use in industry such as working as part of a team, and playing to each others
strengths, looking at the design process from initial briefing to a commercially resolved final
design, and also working to strict deadlines and getting the work finished to a high quality.

3. Aircraft Wheel Rack
My Individual Project is about the exercise rehabilitation for long term
hospital patients. I noticed that after my dad had been discharged
from hospital having finished his chemotherapy he was extremely weak,
struggling to even climb the stairs. I realised that this was a real problem
that is increasing as the NHS tries to discharge patients as early as possible
to free up space and there needed to be a solution that helped patients
engage with life after hospital.
“Health is a state of complete physical, mental and social well-being and
not merely the absence of disease or infirmity.” After chemotherapy is
completed cancer patients are left in very weak health. With no structure
to the day and being able to do very little can often bring on depression
which leads to a downward spiral.
After a broad range of ideas I was finally able to settle on a fun product
that rewarded users for putting effort in. It is to encourage movement
whilst patients are in the hospital to prevent muscle deterioration because
they have nothing to do.

4. Aircraft Wheel Rack
This was my major project at S2. It is a wheel storage rack that Airbus
Military wanted for storing their A400M wheels. There have been many
iterations of this rack and it has been designed in a modular way so that it
can be produced to fit different sized wheels and still stack on top of each
other to save on storage.
The wheel storage rack comes in 3 versions. The first version simply stores
the wheels. This is used for short storage times. The second version stores
the wheels and allows for individual wheel rotation whilst in storage. This is
for small numbers of tyre storage. The third version stores the wheels and
allows the rotation of all the wheels at once. This is for large numbers of
tyre storage when it takes a long time to rotate each wheel individually. It
also provides consistancy within the rotation.
The iterative process has been closely linked with Airbus Military who
performed on-site testing so that we knew the end product was of the
highest quality.

5. Wheel Bearing Protector
During my time at S2 Aerospace, we designed and developed a bearing
protection system for aircraft tyres. This was to tackle the problem of
existing wheel hub protection costing too much, and requireing multiple
engineers to attach and remove.
Our design can be quickly attached and removed by 1 engineer and
has no metal parts. It is significantly cheaper to manufacture then existing
products. It has been designed such that you can interchange the parts
to fit any wheel bearings.
I have been lead designer throughout the project.

6. Oil Drainage Trolley
Whilst working at S2, we got a contract from GE Aviation to design and
manufacture an oil drainage trolley for engine parts. There were specific
dimensional requirements that needed to be followed closely so that parts
would attach securely.
The design incorporated a stainless steel draining tray, a stand for holding
the components, and a rack with a layout that would contain the parts in
a symetrical way whilst maintaining maximum space efficiency.
I ran this project from its start through to its completion.

7. Wheel Transport Trailer
This wheel transport trailer was designed in conjuction with the wheel
storage rack. It is for taking the wheels, wheel dolly and gas bottles from
the storage hanger, to where the plane is on the airfield. It has been
designed to have as low ground clearence as possible and large ramps to
reduce the angle required for moving the heavy wheels and wheel dolly.
It has been designed using materials that will not be damaged when left
outside for long periods of time.
I managed the project and did all the design and development.

10. Contour - Lightweight Seat
In our final year we were able to work with a highly respected UK based
company. They gave us a brief to work in a team of 5 to create a new front
passenger car seat that reduced the weight by a large amount as well as
looking lightweight and keeping the feeling of the companies ideals.
We performed extensive concepting taking inspiration from modern
furniture and renowned architects such as Zaha Hadid. We ended up
choosing a concept that revolutionised the way you actually sit on the
seat by using flexible contact points. It also gave the seat a very lightweight
and modern feel to it.
The design incorporated the use of modern manufacturing techniques
such as selective laser melting (SLM) and had technical features that
would welcome the user in and help maintain concentration when driving.
Modelling was a very important part of the process because we didn’t
know if the concept would even work. We went through many design
iterations based on ergonomic data we were able to collect and created
a loadable model that prove our concept worked.

12. Citrus Juicer
My final year mechanical design simulation project was to design an
electronic citrus juicer which would fit in with a chosen brand (I chose
Braun).
We worked in groups of 4 for the research, which included current market
trends, types of gears and motors, initial mechanism design, calculations
and testing.
I worked on all the calculations and mechanism design which involved
working out what gear trains we would need, what motors we would
need, finding out what the output torque would need to be.
We than split to individual work for the shell design and how it would
actually all come together whilst keeping the brand image. The CAD work
is all my own and proven to work.

Social Networking
The Live project was our final 2nd year project and a culmination of all the
skills we learnt throughout the year. It was a group project of 4 people and
we worked for a UK based company called Omlet.
We were given a brief of designing a chicken incubator and run that fit into
the Omlet brand and revolutionised incubating eggs and the first weeks
of life for the chicks. We were tasked with the ideation, development,
marketing, manufacturability and production within a 4 week project.
We all worked on the design and then split into different areas. I worked
mainly on CAD work to make sure it was completely manufacturable for
injection moulding. The Final model was also done mostly by myself and
another member of the team.
Our candler, the eGlow (shown on the right), was a working model that
lit up when an egg was placed on top. It would press down the spring
loaded LED that would complete the circuit.
Social networking was an important side to the design also. We designed
a system for creating a community and sharing experiences. We created
booklets with the product to help encourage users to go online with their
experiences.

16. Branding
Whilst at S2 aerospace i put a lot of work into rebranding and updating
the face of the company. I helped redesign the website into something
that was far more modern, easy to use, and make it clear what services
the company can provide.
I also designed flyers and documentation about all the different services
and products that S2 provided. This was to be taken to air shows, for clients
that visit, and for our agents to pass around the world to increase our
reach of client base.
It was important to have brand consistency yet instantly know what the
different products and services were which is why i designed a template
that could be reused throughout, whilst only needing the change the
colour scheme to match the product.

18. Observational Sketching
Being able to draw what you picture in your head can sometimes be very
difficult, so it is important that you can draw what you see. These skills can
be transfered between mediums.

19. Modelling
Modelling is an important part of design development and can be done
in many different mediums from simple 2D card, through to blue foam and
clay. Each provide different levels of resolution that can help solve some
problems and highlight others.
