Learning Outcome 1: Understand customer and user needs and the importance of considerations such as aesthetics [D2], and cost drivers
Learning Outcome 2: Use creativity to establish innovative solutions and consider stages of the design process and organise ideas to evaluate outcomes[D6].
Learning Outcome 3: Ensure fitness for purpose for all aspects of the problem including production, operation, maintenance and disposal
Learning Outcome 4: Apply appropriate codes of practice and industry standards [P6] Institution of Mechanical Engineers [IMechE].
Task
Retro-fit Electric Bicycle (EPAC) Design Development
In a group of 6 you must tackle the provided problem brief using Engineering Design tools, techniques and methods.
‘Design a universal retro-fit unit which allows a bicycle to be easily and safely converted into an electronically power-assisted cycle'
Students *must **design for and consider the following areas:
- Power transmission system
- Assembly housing & mechanical attachment
- Safety & Ergonomic considerations
Further guidance and scope is provided in the detailed brief below.
As an initial starting point a basic CAD model of a bicycle for students to design their retro-fit unit to is provided in Aula. Students are advised to make and show considerations of universal design beyond this.
*Smaller student groups can discuss project work-load with module leader. **Students can make use of standard parts in their design.
You must produce a 10 minute video presentation summarising your design process & output.
PEER REVIEW
The coursework mark will be subject to Peer Review. Students that are evidenced to have provided 0%
contribution shall receive a ‘0' mark award and absence of a Peer Review from a group will result in equal award to all contributing group members.
Individual students must keep a log of their individual work, project activity and group meeting contributions. This log can be called for by the module leader to support peer review and mark award for this assignment.
Coursework - Group-project; Design Project
Retro-fit Electric Bicycle (EPAC) Design Development
In a group of 6* you must tackle the provided problem brief using Engineering Design tools, techniques and methods.
The transport sector is undergoing significant change and innovation in response to the demands on sustainability factors. There is a need for the population to make use of varied transport solutions and reduce the reliance on single-passenger car journeys. Many cities are seeing significant infrastructure investment in cycle-ways to connect urban areas to city and industrial centers. Innovation to allow ‘easier cycling' to individuals can encourage greater use of this transport mode on more daily journeys, leading to the provided problem brief.
ADVANCED BRIEF
Power transmission system
Students may make use of existing parts and sub-assemblies for the power system. For example, students are not expected to design novel batteries or electric motors...but should start their design journey on this matter from a problem clarification and scoping perspective. What ‘specification is required'. The overall power transmission system configuration and design is expected to be novel and should be a results the students groups design project activity.
Assembly housing and Mechanical attachment
The student assembly will require a housing to support, secure and protect it. This presents an opportunity to explore further design specification points, standards, material and manufacture to name just a few key areas of consideration. As the product being design is expected to be ‘universal' considerations of how a mechanical attachment or implementation can be need will require careful thought and design.
Safety & Ergonomic considerations
Students should show design consideration and development for the ergonomics of the product and functional features. A starting point is to consider ‘ease of use' an example of this could be ‘product mass' or ‘number of steps to implement'. As always in engineering we must consider safety, it is expected that aspects of safety will be identified and engineering solutions presented.
*example points are just supporting to clarify task, they are not definitive guides or requirements for the submission.
Where groups are smaller than six students, the assignment can be discussed with the module leader to provide suitable assignment allocation.
Viability - The brief mentions ‘considerations made for viability', this refers to the practicality of your solution. Students may consider aspects such as cost, materials used, manufacturing approaches etc....
Students may (and are encouraged to) seek further clarification and guidance from the module team in relation to the assignment brief and task details.
