AUTOMATIC
APPROACH TO PRODUCT
CONCEPTUAL DESIGN
BASED ON CONSTRAINT NETWORK*
Abstract: Product design is considered as the constraint satisfaction problem (CSP), and a new design approach basedon constraint network is proposed and applied to make design automatic partially. By means of constraint extraction,
constraint network construction and operation, constraint chains
are acquired, and then the conceptual design scheme can be got
by decoding the information stored in the design constraint chains, which provides a novelty method for mechanical product design automation. Shearing mechanism of shearing machine has been designed by this way.
