Electric Hairbrush

An example of a design patent. Here, the inventor is trying to get a patent not on function, but strictly on the look and design of the product. Drawings from all 6 directions, plus a perspective view, were required. In this case, I modeled the object with 3D CAD software (which you can see by the shaded colored rendering at top), and generated the six orthogonal views from that model. This hairbrush had an electric heating element inside.
