1.0 THE PROJECT BRIEF
The initial project brief was to promote and support sustainable habits in order to reduce the consumption of single use products
This was then focused in 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.
1.1. STAGE 1 KEY FINDINGS SUMMARY
1.1.1 Reusable Cups
A study by Keep Cup showed reusable cups carbon footprint is 88% lower than compostable cups and overtakes a disposable cup after only 10 days.
The three most common brands are: KeepCup, Ecoffee Cup and Rcup.
1.1.2 Universities
Majority of universities have reusable cup schemes with incentives and are also increasing supply of drinking water to reduce plastic waste.
About 60 000 drinks are sold in reusable cups in a university each year with the number of drinks bought in reusable cups increasing each year.
1.1.3 Pain Points
Carrying and transporting the cup once it is dirty or contains some liquid.
Cleaning the cup between uses during the day.
Forgetting to clean the cup and dirt/stains getting worse and building up.
Keep Cup Plastic
Keep Cup Glass
Ecoffee Cup
RCup
2.0 FINAL PROPOSAL
2.1 THE PRODUCT
The final design, the eco wash and hydrate station, is 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.
With the awareness of sustainability and the requirements of businesses to reduce their impact growing, many universities are currently taking steps to reduce their environmental impact. A key movement is the push to eliminate single use plastic bottles and disposable coffee cups. By doing so they both meet the needs of their customers of which a growing number now use reusable products and increase their marketability to new students. Whilst carrying and refilling a bottle is becoming standard practice the use of reusable coffee cups is still on the rise. There is now a clear gap in the market to provide the facilities needed to support their use as a water fountain does for a bottle.
2.2 COMPONENTS
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. It also features an automated stopper that holds the cup down during the cycle. The wash cycle is activated by the user pressing a start button and a series of lights act as a progress bar to indicate wash cycle progress.
The bottle refill side provides chilled water and is activated by a push and hold button. Both sides feature an internal drainage area at the front of either compartment.
2.3 USER PROCESS
To wash a cup the user will walk up to the station, pour away any excess fluid at the front of the compartment and then place the cup upside down over the nozzle on the drainage plate. Once the cup is in place the user presses the start button which activates the cycle. The door automatically closes, and the stopper moves down until it senses the top of the cup and stops. The door then locks and the wash cycle commences. LED lights at the top indicate the process completing. Once complete the door unlocks, automatically opens again and the user removes their cup. The progression of use is displayed within the storyboard:
3.0 DESIGN DEVELOPMENT
3.1 CHANGES
The table and annoated images highlight the key design changes that were made as a result of prototyping and development in stage 2. Most decisions were made as a result of multiple tests combined with user feedback. The majority of user feedback was collected during a series of overall prototyping feedback interviews with users which are expanded on within the evaluation section. User evaluation of the final resulting design was then carried out and further design changes suggested. For more information on the development of the rotating nozzle and air blade see portfolio pages 34,35 and 66,67.

6 DESIGN CHANGES
The diagram and table summarises the design chnages to be made as a result of final design evaluation. Overall the feedback was positive with some minor changes identified. In addition to these chnages identified if this productdevelopment was to be continued to manufacture and sale, due to its complexity further safety testing, user feedback with a market ready prototype and furher manufacturing development would be required. These were not completed in this project due to the time scale and input of only one person as well as delays caused by covid isolations.
7 DFM
The product is made up of a large number of varying components and units. A large majority of these would be purchased as off the shelf items and then assembled on site. Some units such as the water cooling unit would be developed with a subcontractor to fit the product requirements and then delivered as a unit for final assembly.
In addition many of the custom plastic parts such as the casing and internal funnel from the fan to compartment air blade would require mould design and set up with subcontracotrs and add to the start up costs. To increase the sustaianability of the product companies who can guarantee renewable energy consumption only, waste recycling and reduced shipping would be chosen. Further more the parts would be designed to reduce the number of materials and componeets, particulalry fastners to reduce consumption, make it easily repairable and designed for dissasebly at end of life. Furthermore a lifecycle assessment of the whole process would be completed.

7.3 Key Components
Wall Mounted
The unit is wall mounts and connected to the buildings water supply, electricity and waste disposal system. This allows for a continuous water supply, power for the refrigeration unit, electronics and interface and disposal of waste water without manual intervention. A stainless steel bracket will be supplied to fix to the wall that the main product is hooked onto.
Water Cooling
Hermetically sealed refrigeration system provides chilled water. In hermetically sealed compressor, the compressor and the motor are enclosed in the welded steel casing and the two are connected by a common shaft. This makes the whole compressor and the motor a single compact and portable unit that can be handled easily. They also require less maintenance, have a longer life span and are easier to install. The cooling system works by a compressor which pumps the refrigerant through the condenser which features a fan to assist cooling as the heat it radiated. The refrigerant then reaches an expansion valve at which it is able to suddenly expand into a gas, taking heat out of the surrounding environment. It does this as it passes through the heat exchanger where the water is fed through to cool it.
A direct chill system will be used where within the heat exchanger the water is passed through stainless steel piping coiled alongside copper piping carrying the refrigerant gas. This means the water can be cooled instantly as it travels through the piping and does not need to be stored in a tank. It also means the water never comes into contact with the atmosphere.
Air Supply
The product also features an air supply produced by a fan which is split between the nozzle and the external air blade. The fan unit would be purchased form a subcontractor and them assembled to the air blade funnel and nozzle onsite. The air blade funnel would be cutom deisgned and manufactured using injection moudling.
The water supply is plumbed into the mains at the wall and is attached to a filter.
