The Brief To promote and support sustainable habits in order to reduce the consumption of single use products.

Focused To design a product which assists with and promotes the use of reusable cups in a university environment to increase uptake in reusable cup schemes and in turn reduce disposable cup waste.

Final Design A combined reusable cup washer and bottle refill fountain making managing and using your

reusable items on-the-go simple. The stations will be wall mounted within universities in key locations for students and staff to use as they go about their day-to-day activities

Key Feature The wash half features a cylindrical compartment with automated revolving door and wash cycle featuring hot wash, cold rinse and air dry supplied as jets through a revolving nozzle central nozzle and wall nozzles.

Research

The Problem Production of disposable cups relies heavily on natural resources.

They are difficult to recycle due to the plastic lining which is difficult to separate.

Less that 1% of the cups we produce are recycled.

Large energy consumption to create and dispose of single use. Cups.

The Solution Study by KeepCup showed reusable cups carbon footprint is 88% lower than compostable cups and overtakes a disposable cup after only 10 days.

Reusable Cup – Pain Points 1. Carrying/transporting the cup once dirty or contains drink dregs.

2. Cleaning the cup between uses during the day.

3. Forgetting to clean the cup. Dirt and stains building up.

SURFACE MODELLING Custom mask design: Solidworks I designed a respirator mask to protect against small droplets and particulates with replaceable particulate filters and an exhalation valve. In addition, it also has a custom fit seal and a filter replacement reminder function.

For this project photogrammetry was used to produce 3D scan data of my head and shoulders. This was produced by taking multiple photos using a single camera which were then combined to create a 3D virtual model

Design Development

Surface Analysis

Surface analysis allowed problematic areas to be identified so that new patch layouts could be tried to achieve high quality surface continuity.

Industrial Design & Technology

Brief:

To identify a persona and design a product for them looking to future technology, drawing inspiration for form, style and aesthetics from surrounding research.

Industrial Design & Technology This module was about looking to future technology and developing design research and ideations skills. To support the presentation boards I also completed a log book. This included a range of physical and digital sketching drawing inspiration from research analysing and extracting forms, colours and materials. Digital mash ups and some basic prototyping was also used to inform development.

As one of the first modules of my masters in design, this was a fast learning curve transitioning from engineering studies. For this module I learnt a range of new programs including procreate, InDesign, Sketchbook and started to develop new skills such as digital sketching and rendering which I continue to work on.

The Brief: To design a device to increase the reliability and repeatability of the allergen skin testing process.

Key Considerations: To consider sustainability within healthcare looking at the constraints for reuse of products such as lancets that pierce the skin. As a result a design to minimise material consumption per lancet was pursued.

Detailed Design

Prototype and Testing One of the foam models and the 3D printed prototype used for form testing. Due to being at home during the pandemic materials were limited.

Ergonomic testing of casing design looking at different hand positions. If this project were to be extended further moulds would be creates and tested on a range of hand sizes.

Lancet Design

Water droplet 3D printed deposited held stackable design around the tested with water. needle and straw by surface tension.

Cad models of mechanism development.
