The Challenge
The client wanted to use a gas system to generate the required energy for a portable consumer device as the power needed could not come from a corded or battery system. This required a major redesign of the entire product.
Our Approach
We were tasked with designing a ‘works like, looks like’ model from scratch through to transfer to manufacture, including the electronics, gas system and design.
This work included:
- Developing our own electronically-controlled valve to control flow rate
- Understanding of chemical reactions and catalysts
- Using CFD analysis to design components for optimum flow, mixing and efficiency
- A conduction path using a heat pipe to transfer the energy to functional elements of the device
The Result
Over 2 months, Sanner conducted market research on existing products from the clients’ competitors and produced a product specification.
We then developed a benchtop demonstrator after conducting initial basic research on reaction kinetics, heat transfer, electronic control and gas flow. Once the performance was demonstrated we built a product demonstrator which was in the correct form factor and was fully operational including full electronic control of the gas system.
