Sometimes the silly ideas are the winners. This is what product development contests are for. Hard work will compensate for the lack of imagination.
The more people you gather, the better your chance of finding the right idea. The process of product development and design is iterative and can be improved with several cycles. Every cycle makes little changes to improve upon a previous version or idea. Each new version has something that was impossible to implement in the previous version. So you are improving upon something that was already good but had the potential for improvement.
