I am currently also in the BME Capstone class, as I am in my senior year. I also had to make an extensive list for the design requirements and customer needs. We met with our customer and they told us exactly what they wanted and we worked towards building the device in a specific way. We also had to meet with their design requirements, and they would often reject any design that they seemed would not work in the setting of the body. I cannot give much away about this project, since it works with an outside company, but I can tell you that explaining our design to the customer vs someone on the street has to be totally different. Our design should be easy to understand and visualize. It should make sense for why we need this product on the market and why the other products have failed. It should also follow any FDA regulations as well as the company’s regulations in testing the product and utilizing their resources to make a product that they will be proud to use in the future.
