With the development of CSCW techniques

applying cooperative design methods into conceptual design is a hot and interesting research project in product design area now. Layout design and ergonomics design are two sub processes of conceptual design which affect and restrict each other. Function face is a significant concept in the area of industrial design. It is classified as physical function face and physiological and psychological function face. Function face can be used to characterize the relationships of the product components and the human. In order to cooperate layout design and ergonomics design

the function face is adopted as the basis to distribute the conceptual design tasks

and the function face based cooperative design process and method are put forward. According to the characters of layout design and ergonomics design

a description method of computer supported cooperative design model is introduced. This design model can suit the changes in cooperative design. Finally

an applicable scheme of the computer supported layout ergonomics cooperative design system in motorcycle design is described. This system is based on Client/Server mode and consists of a layout design client

an ergonomics client and a cooperation server.
