TRIO Natural Disaster Emergency vessel Individual Project | 9 months
01
Design and prototype a solution to the effects of life threatening natural disasters. - Self appointed brief.
TRIO
Design a product that can aid those in danger from natural disasters, provide clean water, communications and heat. Applying all I have learnt from previous projects for my major project, where I have set my own brief. Conducting my own research and going through each stage of the design process within the 9 month period.
THE ISSUE? There is no uniďŹ ed product for this kind of situation, it’s all supplied as a kit.
CONCEPT DEVELOPMENT The construction of these products are not adequate for the dangerous environment
Some products are meant for other adventurous environments and therefore not suitable for life threatening situations.
PROTOTYPE DEVELOPMENT The life cycle of these products are not properly thought about as governments and NGOs send aid to foreign countries

Injection Moulded Ground Coffee Scoop Group Project | 12 Weeks
02
Design and Manufacture a polymer widget that promotes a brand
This design has no association with the company BIALETTI
Designing a coffee scoop widget with a SHOT WEIGHT of 25g and MANUFACTURING the mould tools required
CUSTOM CNC TOOLING
Good planning and time management resulting this project going smoothly without any major problems, some components took time to setup and manufacture however I was able to contribute my end and manage my workload with other projects going on at the same time.

MANUFACTURING
1
Take stock material and rough cutting down to size
2
Using the produced engineering drawings to make cuts and follow the steps to produce each insert
3
Check using measuring equipment before surface grinding to ďŹ nish
MANUAL MACHINING
INJECTION MOULD OUTPUT
4
Test injecting polymer (LDPE) and making macro adjustments.
Coffee scoop that PROMOTES BIALETTI which helps MEASURE a cupful of coffee grounds
Breathable Gaming Mouse Individual Project | 11 Weeks
03
Reverse Engineer and Model a Product for AM
This design has no association with the company GIGABYTE
Chosen to redesign a gaming mouse to add BREATHABLE COMFORT and interchangable side surfaces using ADDITIVE MANUFACTURING
SURFACE MODELING
At times the process I was taking dead ended and I needed to rethink my process, however each time I learnt something and I could rebuild my CAD model in double the time. More time could be spent next time thinking about AM processes and how what I design can be acheived by SLS, SLA or FDM.
COMPONENT DISASSEMBLY AND MODELLING STRATEGY
SURFACE ANALYSIS
DEVELOPMENT PROCESS
1
Surface planning then to split surfaces into primary and secondary surfaces. Iterate until the surfaces are of a high quality.
2
Build surfaces using a range of surface techniques and create an assembly from the master part
3
Thicken pieces and create separate components, change for AM and create the era mesh geometry by interpolating the format in other software (RHINO)
4
Analyse the Assembly and generate engineering drawings and 3D print slice path in Cura
Breathable Gaming Mouse
FEATURES RGB INDICATOR
DPI ADJUSTMENTS
SIDE BUTTONS
BREATHABLE MESH
Automated Coffee Aeropress machine Group Project | 8 Weeks
04
Manufacture a solution to automate the coffee making process of an AeroPress
This design has no association with the company Aerobie
Integrating electronics and mechanics to DESIGN and MANUFACTURE a twin directional plunger with water pumping capabilities
CAD ASSEMBLY
My design from the initial 3 concepts was taken forward after evaluating the feasibility and ease of manufacturing of the range of designs. Since this was the proposed design, I was leader of the project and delegated work to my team and managed the overall progress along with manufacturing and designing of the electronics and some of the metal manufacturing.
MECHANISM CONCEPTS
COMPONENT FLOWCHART
What I learnt was that having a good CAD model to plan manufacturing helped a lot but it doesn’t point out all the feasibility issues or manufacturing constraints. However as a team we looked at alternative solutions to a problem within a high pressured time deadline.
DEVE LOPMENT PROCESS
1
Standard parts such as bars, mounting hardware and were bought in and measure up and implemented on the CAD model
2
Other components were hand machined and manufactured in-house using the engineering drawings
3
Electronics were developed adding each component until the hardware and software was working as expected.
4
Issues and challenges that came up were implemented and features changed while sticking with the brief
5
Electronics and mechanical systems were incorporated together into one machine with a more permanent structure
AUTOMATE the AeroPress process adding FEATURES to the coffee brewing experience
HOT WATER PUMP
COFFEE INTAKE
COFFEE CONTROLS
