Novel device development - the UPC approach (2)

De-risking the project - after concept(s) selection we explore the fundamentals of how the device will work in a range of proof-of-principle rigs. It is a project time for ups and downs, but a clear head is needed to ensure only working device paths are taken forward. Experimental work is conducted where possible, but computer-based analysis is also used, where it has a successful historical use or is the only realistic predictive tool. Tolerance Analysis for complex mechanisms is often very telling at this stage. Patent review - UPC will support and assess the impact of this work.

Fully-engineered prototypes (FEP) - These will be off-tool but assembled and filled by hand in jigs. FMECA's are the norm at this design stage. At UPC we also 'design for manufacture' at this early stage to ensure the solutions proposed can be made in volume. This approach takes more effort and requires an in-depth knowledge of device engineering and manufacture, but reaps rewards longer-term . We like breaking prototypes to understand their performance limits rather than just ticking 'pass' boxes. Creep, stiffness, drop, sand ingress, water ingress, tumble, hot and cold storage as well as vibration testing are all part of typical verification programmes.
