ABOUT ME Hi, my name is Michael Bull and I am a third year student studying Mdes Product Design at Coventry University. Product Design is a subject I am passionate and euthusiastic about and is what I consider as my ideal career. My interest for Product Design grew from when I noticed the differences between things that were designed for a purpose of being useful and things that would just be there to please the eye. I am currently seeking a design placement opportunity to gain experience in a commerical environment to build on my growing set of skills.

60% 40%

Average Age for Lower Limb Amputations (UK)

World Amputee Population: 10 million

Causes: • Vascular disease 90%, consisting of atherosclerosis 60%, diabetes mellitus 30% • Trauma 5% • Neoplasm 1% • Other causes 4% Issues: • Stumps change shape over the year sockets need adjusting or replacement. • The needs of amputees change. • Prosthetic replacements change and the devices require care and maintenance. • New, appropriate devices are being constantly developed and these may be available to the prosthetist to supply.

5 Key Insights and Challenges

Adaptability

Versatility

Comfort & Fit

Maintenance

Feedback

After looking into issues that amputees and prothetist have to gain insight and understanding challenges they face. I then narrowed it down to 5 key issues I wanted to target.


Concept Development Concept/Solution Overview

Then came up with 4 different proposals to cater to the respective challenges that were faced to ensure a holistic and comprehensive solution.

Structure Improvement

Modular Attachment

Conforming Vaccum

Smart Technology


Usage Scenario Stump Volume Alteration

One of the issues with prosthetics in general is that the limb may change over time, which will affect the fitting of the prosthetic.

1) Removing the Prosthetic Leg

2) Heating Oven

3) Protective Lining

4) Wearing Socket

5) Activate Vaccum

With the use of conforming Polyurethane Liner which adapts, it saves the cost of replacing the entire socket when the residual limb volume fluctuates.

Concept Exploration Exploring Feet Form

Connector to the main leg section.

Grip Options


Concept Finalisation Inside of the prosthetic leg, there is a Pylon which gives the leg support and adjusts in height to suit the user.

The pivot allows the user to move the attachment, which allows them the move about.

Either a Ice Skating Blade or a ski.

Ski Prosthetic Attachment Two buttons on the side allows the user to disconnect the foot attachment and replaced with another one.

Gives the foot support and when supressed, it returns back to it’s orginal form.

Polyurethane Grip

Running Attachment

Connects to the socket and locks the foot attachment in place.

The pivot allows the user to skate like a professional and move the top of the prosthetic into the move into the correct position.

Ice Skating Attachment

Rock Climbing Attachment

Indented section at the front to adapt to different rock forms. Inspiration from hiking boots with a modern take.


AdaptRunner The AdaptRunner Prosthetic Leg changes the very experience of being an amputee to help them adapt back to a healthier lifestyle and blend back into society. It is able to adapt to different solutions that the user may put it in by changing the foot, to suit the type of exercise they might do. Instead of switching the entire prosthetic between sports, an open and diverse range of attachments allows for manufacturers and designers to Design feet catering to different sports - much like our shoes.

The height of the leg is adjustable to suit accordingly to the individual users, by activiating a system that adjusts it for the users.

Rubber Hexagonal Patterned Outsole. The sorbothane structure provides better shock absorption as well as improve the overall structural integrity to cater to both planarflexion and dorsiflexion, unlike conventional products which mostly cater to one.

Carbon Fibre Structure.

Release Buttons with Rubber Grips.

Featuring an elevated vacuum suspension System, supported by a PU foam liner which softens when heat is applied, AdaptRunner ensures comfort and is able to adapt according to individual users.


Lexon Visual Brand Language 1 Week Individual Live Project ‘‘To explore the brand and design a chopping board that would fit into the design language of the company.’’


Visual Brand Language Research

A French based company that creates unique products that are designed to enlighten daily life in a variety of environments. Either a designer or a group of designers take part in the aesthetically pleasing collections. Lexon designers come from different parts of the world, which provide different views to Lexon due to its origins, cultures, personalities and diversity of experience. I have researched into Lexon’s Visual Language and Brand Values by looking at existing products and highlighting brand qualities they focus on, which are product diversity, simplicity and function.

Diversity

Simplicity

Function


Concept Development 1

Extra board to place waste or other foods.

Bamboo board

2

Traditional and simplistic design

HDPE or Polypropylene board with a bamboo drawer

Drawer is able to come out to be washed.

Slot to store a knife within the board Place either utensils/ Knifes or waste food.

Polypropylene

3

Raised boundary around the edge of the board, to keep food.

Drainage Walnut Board

Different coloured frame for each board, as part of a set.


Concept Finalisation After completeing a task analysis of using a chopping board, I found a problem with picking up and lifting the board when moving food and waste. Through brainstorming and sketching, I have created a solution for this problem by having a part of the board raised from the surface and a hole, making it easier for the user to pick up and lift.

Bamboo - Frame

Cutting

Section to keep waste food and extra food out the way.

Lifting

Moving

Able to switch the 6 different boards to suit the types of foods.

Maybe having a two different coloured boards on each side.

3D Form Development 5 Week Individual Project ‘‘Using Clay to model an animal using 4 themes, Fluid, Architectural, Monolithic and Dynamic.’’


Inspiration


Form Development This page shows inital sketches of the Raccoon clay model. I was challenged to modify form based of different themes; Fluid, Architectural, Monolithic and Dynamic. The right shows my ideas based of the inspiration with the different themes.

CAD Development Skills 4 Week Individual Project

‘‘To replicate an existing iron using Rhinoceros 3D.’’


Process Phase

1

This project involved using Rhinoceros 3D (CAD) software, creating a 3D model of an existing iron. I began this project by drawing orthographic views of the iron which were then imported into the CAD software and used to create the 3D model. I also dismantled the existing iron to be able to understand how each components are made and assembled together. The next page shows a Keyshot render of my final model.

Gardening Project

3 Month Individual Project ‘‘Design electric secateurs that could be used by elderly consumers for use in the garden.’’


Persona User Group: Gardening Elders Roy (74) and Mary (72)

Retired for 7 Years. Bungalow in St.Ives, Cornwall (UK) Large Gargen: Joint Projects and place for grandchildren to leran and play. Social Life: Meals, Coffee Mornings and Playing Bowls with friends and family. They are both passionate cooks in which they use produce from their garden. Roy: Arthritis in his hands. Mary: Loss of hearing in one ear. ‘‘We love gardening as it requires patience and careful attention. We are both restricted to the amount we can do, so we appreciate help when it is needed.’’

Human Factors

Two types of grips used: Control and Power grips.

Research: Task Analysis The analaysis was carried out on Bosch electric.

Neutral Hand Position.

1 The position of the trigger is

Where contact is made with the product.

Similar hand position and grip when using electric secateurs.

It is vital that the users physical and emotional needs are understood so that the product can and be tailored to the end user.

Emotional Requirements

1) Sophistication The product should meet the users visual preference and give the user a sense of purpose and satisfaction when using the product. 2) Therapeutic The user should feel a sense of peace and joyfulness as they continue to be a rewarded and satisfied experience. 3) Comfort It should give the users the feeling of physical ease, relief from pain or stress if the users has arthritis.

uncomfortable - gap between the handle and the trigger.

2 The form and weight of the

secateurs put a lot of strain on the wrist due to the way the users holds the product.

3 When wearing gloves, there is not much room to get the operating finger on the trigger due to being covered by plastic.

Stainless Steel Blades

Safety Catches

Guards


Dual locking system for safety.
