In our senior design capstone project for BME, the design inputs were developed from two sources: market research and customer needs. In order to develop design inputs, market research was conducted in order to understand what products and devices exist on the market to fulfill the given need/function. Secondly, customer needs were taken into account to help flesh out a product that would stand apart from the existing competition. These were the primary considerations when developing design inputs. Other considerations, such as disposal, safety, and regulatory conditions will also be taken into account when developing the design inputs. Lastly, cost will also place constraints on design inputs.
