Abstract�� The ontology and ontology mapping technology were introduced into the conceptual design schema generation field. A new conceptual design scheme generation method based on ontology mapping was proposed 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 ontology-based knowledge presentation and product conceptual design schema satisfying the design requirement was found in the product design knowledge database through the ontology mapping algorithm.Finally, the correctness and validity of the new scheme generation method were tested and verified through the drive device of crane lifting mechanism design example.
