The machine aesthetics, the new aesthetic appeal of the machine in industrial age, will still have a profound impact on people's aesthetic perception of industrial products for a long time. It is believed that geometric shapes is the visional language of machine aesthetics, so two way of design to machine aesthetics are put forward in this paper: one is to design with primitive geometric shapes, the other is to design with geometric proportion or number to regulate the quantity relationships that exit in the parts or whole of a product. At last, two products were given to prove the theory.
