High-Power Attachable Biking Dynamo Design -- 2
Budget: $15 – $25 USD
I'm in need of an engineer with expertise in both electrical and mechanical engineering. Our aim is to design a high-power attachable biking dynamo/alternator for bicycles.
The primary objective of this project is to create a device that can generate and store significant power for storage in high-capacity batteries. This dynamo/alternator should deliver a high power output, mainly focusing on efficiency, ease of use and weight.
Key requirements:
- Designing a high-power dynamo/alternator that can support extensive power needs.
- The device should be attachable to a standard bicycle without impacting its performance or aesthetics.
- Prioritizing power output over size or weight, meaning the final product can be robust as needed.
Your role will be to:
- Combine your expertise in electrical and mechanical engineering to create a prototype.
- Ensure the final product is not only functional but also practical for cyclists to use.
- Potentially provide suggestions on storage solutions for the generated power.
Ideal skills and experience for this job include:
- Proven experience in designing high-power dynamo/alternators or similar energy generation devices.
- Knowledge of both electrical and mechanical engineering principles.
- Familiarity with designing for bicycles or other sporting equipment would be a plus.
Interview questions below are mandatory:
Q1: If current dynamos range between 3W to 7W, but alternators can go up to 100W. Can you make use of existing technology to capture up to a 100W from biking? (For instance using more then one dynamo or alternator or combining both) If yes, how?
Q2: Can you create a hybrid system (an in between-system that can be mid-range between producing the low watts of a dynamo and the high watts of an alternator)? If yes, how do you aim to achieve this?
Q3: Are you able to optimize the energy capture and storage efficiency of the system in a lightweight manner? (no more then 1kg - including batteries). If yes, describe in brief how you will achieve this?
Q4: What technology can you make use of to maximise efficiency in the system and minimize energy loss?
Q5: Based on all your responses previously provide a breakdown of the estimated design costs, implementation needs, and timeline required to achieve a functional prototype?
Q6: What can you deliver in two weeks as a proof of concept? Provide detailed description, breakdown of deliverables and rate
