A new conceptual design scheme generation method based on ontology mapp ing was pro2 posed to solve the problems of design knowledge reuse difficulty and low accuracy in conceptual design scheme generation because of different knowledge description approaches in traditional conceptual scheme generation methods. The proposed method constructed product design knowledge database in the way of ontology2based knowledge presentation and product conceptual design schema satisfying the design requ irementwas found in the product design knowledge database through the ontologymapp ing algorithm. F inally, the correctness and validity of the new scheme generation method were tested and verified through the drive device of crane liftingme
