01 Engagement Ring Packaging A project aiming to redesign packaging to put emphasis on sustainability. I added value through product life cycle extension.
Concepts Situation
While recycling everyday materials is an effective way to reduce our impact on the environment, reduction in the amount actually going into the cycle in the first place is the best way forward.
Concepts
Value added through longevity of packaging. Concepts focusing on ring presentation and display when not in use.

PERSONA PROFILE
REQUIREMENTS SUSTAINABILITY
- Test method: research of materials, manufacture - WBSI environmental impact is reduced
80%
70%
Would keep packaging that could be re-purposed
Would be more inclined to buy sustainably packaged goods
60% Think packaging is indicative of quality
70% Keep jewellery boxes
NEEDS: - Houses a standard sized engagement ring - Opens to reveal ring - Able to stand upright while open WANTS: - Aesthetically pleasing - Has an interesting opening mechanism DESIRES: - Displays the ring when not in use - To be sustainably manufactured - Enhances proposal experience
50% Display their jewellery using a display joint
FEASIBILITY CONSIDERATIONS

Would use reusable jewellery packaging
Have nowhere to store/display their rings
Think existing jewellery packaging is uninteresting
- Test method: record dimensions and weight - WBSI it can fit in standard pockets
SAFETY
- Test method: prototype testing - WBSI it functions with no safety hazards
COST
- Test method: consider materials and manufacture - WBSI it doesn’t raise the ring price High Priority

02 Prototyping Project Developing CAD and manufacturing skills through designing a sharpener with multiple mechanical functions.
Ideation + Development Development
3 mechanisms were developed as part of this project
Hinge Snap Fitting
Slider
Final Design
Prototyping Process
Making and Finishing Formed a mood board based on a theme then produced 6 different concepts to explore different forms and mechanical functions
Initial Ideation
Concept Development CAD Modelling
This design was then modelled using Solidworks to visualise and test mechanics. Tolerances were added based on how tight the fit was required to be
Assembly Drawing Cost Calculation Manufacture
The design with the best mechanical function was selected and then developed further to better understand the mechanics of the system
An engineering drawing was produced using Solidworks and dimensions and cross sectional analysis was added to fully understand and define the design A costing document was produced based on the volume of the design taking into account material costs
The Solidworks file was converted into an stl and sent off to be 3D printed using ABS.
Post Processing
The final product went through post process sanding and finishing using acrylic paint with a spray on primer. It was then assembled using a m3 screw and bolt to secure it.
Materials Used: - ABS - M3 screw - M3 hex nut - Acrylic paint - Spray primer - Polymer sharpener
RESOLVED
03 Arthritic Alarm Clock A project aiming to improve ease of use for individuals with arthritis interacting with digital alarm clocks. The main aim was to develop design detailing skills using CAD to produce engineering drawings.

Do you enjoy your commute?
What aspects of commuting do you enjoy the least?
How do you cope with tedious commutes?
YES NO COFFEE -Ticket collection -Time consuming / waiting -Crowdedness -Early morning tiredness
REQUIREMENTS AESTHETIC
Disposable coffee cup specific bins Designed to promote the separation of materials for recycling Ratio of space allocated for cups : lids : liquid is 4:2:1 Left has visual feedback from progress via a clear screen
Bin to promote recycling through interactive fun Bin gives a fun incentive to recycle It is a very simple and easy to use design meaning everyone can interact with it
Both bins require additional effort put in by the user to separate each component and commuters will not be willing to put in this effort
A higher effort bin to use but one that is less practical and more of a novelty structure
- Medium priority - Test method: client feedback - WBSI it appeals to potential users and encourages interaction - Source: user
SIZE & WEIGHT
- Medium priority - Test method: record dimensions and weight - WBSI it fits and is non intrusive on the train station platform - Source: research
FUNCTION
- High priority - Test method: must separate coffee cup parts and also be fun to use - WBSI it can have the intended effect - Source: user
ENVIRONMENT
- High priority - Test method: place in environment and analyse - WBSI it is attractive and integrates well with surrounding aesthetics - Source: brief
-Part time work -Netflix -Coffee

Final Design Final Design
I concluded on a design which subtly promotes recycling through streamlining of the process. This recycling point allows cups to be separated into their components effectively with little user effort.
Insert lid of cup into lid remover
Let go of cup to dispose of
Lift upwards to take lid off
Cup will fall into correct area
Liquid will drain into drawer
