To be directed against the problems of products design,a knowledge supported classified constrain method was put forward.This method classified different units of products based on engineering knowledge.Different levels of constrains also had been judged.Knowledge supported classified constraint module was constructed.The customer needs were effectively converted,transfered and calculated,and the product design blueprint was gained automatically.Using this method,an elevator well road layout design system was built.The system had been authenticated when used in the elevator well road layout design.It has solved errors such as human-computer interaction errors,reducing the manufacturing error ratio and development cost as well.
