Design inputs ensure that your design requirements correspond with the intended use of the device, with a strong focus on the end users needs. After doing some research on design inputs, I’ve found that the inputs are based on the end users needs, but aren’t simply a list of the end users needs. For example, if you are going to be developing a new syringe for home injection, your end user/patient may want the device to be easy to use and safe for home use. But, your design inputs wont be “easy to use” and “safe for home use”. Your design inputs will be developed by the engineers and turned into quantitative and measurable design specs.
