ChemAware My brief was to design an ‘Internet of Things’ device that is able to test recreational drugs for purity and impurities. It then alerts the user as to whether the drug is safe to take or not, whilst also anonymously feeding into an app linked database to inform users in the area.
Problem
In 2018 there were 4359 drug related deaths 729 of these deaths were as a result of MDMA and Cocaine 10% of these deaths were people aged 29 or younger
Ideation sketches
User research I made foam models in order to ask my peers questions about the design and to see how they interacted with them, allowing me to develop my work.
Appearance model
The model took approximately 3 weeks to make involving 3D printing from a CAD model, sanding and painting to get a final finish. Considerations I had to make were that the design had to be non-threatening and discreet to allow people to have the product in their everyday carry and potentially trust it with their life.

Form redesign
I am always looking to improve my design work through learning from feedback. For this project I wanted to experminent with a more intuative form and different material types to give a more user friendly and premium feel.
Ricochet
Ricochet The brief for this project was to design a concept speaker body around internal components given to me under the context of “rugged design.”
Form board
Final design
Renders
I used Solidworks Visualize to render my speaker model which allowed me to evaluate the final form more critically, bringing up issues. For example, altering the balance between its form and function, potentially making aesthetic decisions based on how the product would work most effectively.
ovOid This was a project where I was tasked to reinterpret the functionality of a basic toaster. from changing the way in which people retrieved their toast from the machine to tailoring the internal components to facilitate this function.

Materials research Recycled ABS is an ideal material for the body of the toaster. - It comes in a range of colours - Non-toxic - It is tough and durable enabling it to have a long lifespan - It can be recycled into other ABS products - It can be injection moulded on a mass scale
Ceramics are a sustainable alternative to Mica insulating sheets. Ethical source of extraction More abundant than Mica Has properties similar to Mica Can be recycled -
Steel offers many excellent properties for the metal internals of a toaster. - Steel is very durable, guaranteeing a long lifespan - It is the most widely recycled material in the world - It can have finishes applied to it and still be recycled
Concept exploration Toaster concept 1: The main body is made from injection moulded polypropylene, with the dials being made from extruded aluminium with both of these materials being recyclable.
Concept 3: The handle and the instruments are made from extruded aluminium and the body is made from pressed steel which are both sustainable in terms of their recyclability.
Toaster concept 2: The main body is made from pressed steel and glass which can both be recycled. The handle is made from pine, a fast growing wood, therefore making it more sustainable than other woods.
Design in context
Putting my design into different contexts allowed me to see how the materials and the forms would realistically integrate within the environment in which its use was intended. This gave me the opportunity to evaluate my work and take what I learnt into my future designs. For example, my toaster design needs a large amount of space to its left side to allow it to open, furthermore, you cannot place the back of the toaster flush against the wall as it could cause condensation build up or potentially be a fire hazard.
Scenario board The user adjusts the two dials that control slice number and amount of time to toast according to their preference.
The user wants to make toast and puts the slices into the toaster by folding the lid into the body.
The user then takes the toast out of the elements via the lid system which allows the toast to cool before taking it out and eliminates the risk of electrocution through trying to ‘un-jam’ the toaster by using a metal utensil.
This project was for design week where a brief was assigned and I had a week to come up with 3 pages in response. The HEXR brief involved using the company’s sub mm scanning technology ,which they use to 3D print bespoke bike helmets, in order to make a mass manufactured product that was able to specifically fit each individual user. I decided to design a posture correction device.
Persona
Khai Robinson “I love my work, but if I’m not in the right head-space I know I can’t deliver to the best of my ability”
Biography
Pain points
Goals
Age: 32 Job: Software Developer Location: London About: Khai loves his job and is often in the office working late, apart from Fridays, which he spends going to a bar or restaurant with his long-term girlfriend, Jessica, for dinner. He always makes time, however, to go to the gym or for a run after work as he believes strongly that it helps him cope with the long work days.
•Khai is worried that the time he spends at work is having a negative impact on his relationship and he feels as though he is losing touch with Jessica.
•Running the London Marathon has always been on Khai’s radar and he feels as though this could be the year to do it.
•He feels as though he is being injured more frequently in the gym, due to poor posture, from sitting at a desk for long periods. This causes him frustration as he is unable to exercise properly after work.
•Despite feeling a little distant from Jessica, Khai is planning to propose and to focus on spending more time with her.
Story board
Posture Correction System
alleviating back pain
The spine segments are made from injection moulded ABS and fit together via circular inserts which allows lateral movement. The inserts can be added or reduced where required to fit the user’s dimensions.
The Posture Correction System is ergonomically designed to correct a person’s posture in order to relieve back pain and other associated problems. The device is uniquely able to specifically fit all users through the addition or subtraction of vertebrae on the spine and spacers on the hips and shoulders. The device is tightened or loosened on the waist and shouders via the elasticated fabric straps. The device has a low profile and acurved shape, so it is able to be worn under clothing, when at work , for example.
The spacers on the shoulders and the hips are made from injection moulded ABS and have the same joints as the spine sements, multiple can be joined together, or removed, to increase or reduce the width of the waist and shoulder supports.
This project involved creating an injection moulded promotional widget for NERF. We were given a list of constraints that we had to work with and create a mould tool to create our widget whilst overcoming these restraints.
Mould tool development
After designing the widget I had to design the mould tool to create it. This involved making inserts and experimenting with ways in which I could assemble the widget parts.

The engineer drawings required me to use tolerancing which meant I had to use BS8888 and BS4500, which allowed my drawings to be as unambiguous as possible meaning I would be able to use them in the workshop.

Widget function
The function of the widget is to screw onto a coke bottle thread and the user is able to squeeze the bottle and the nozzle acts as a barrel converting the bottle into a water-gun. This increases the lifetime of the water bottle, keeping it out of landfill by giving it a secondary purpose.
Exploded view
The widget relies on a pressure fit to assemble the two parts in order to make sure that I was able to mould the two parts.
