Demo of your concept rendering(s) and an early version of a working prototype.
Create a polished rendering of your product concept. The goal is to create a drawing that best communicates the technology of your concept to someone who is not on the immediate team. Pick a rendering style which you feel is appropriate to best communicate your concept. Text should be kept to a minimum as this is an exercise in communicating through graphics. Rendering can be done by hand or with a computer-based rendering package. If applicable, include views that show product in use. Use this rendering in your presentations and reports as the single graphic which best describes your product. Revise the rendering as the design evolves. If you have more than one concept, make more than one rendering. You may wish to consult books on product rendering, or consult with an industrial designer to learn about communicating product concepts through rendering.
Create a physical prototype of your primary concept. Create multiple prototypes if you have more than one concept. Prototypes should be physical so that you can demo their key operating principles. They need not be to-size. For example, a small medical product could have a 4X size prototype.
Create a polished prototype of your primary product idea. This is a prototype that you feel comfortable showing to all stakeholders. It should be considerably more polished than anything you did Fall semester.
