Product Variant Design Based on Extensible Modular Method

Variant design is the main form of most manufacturing enterprises. In this paper, an extensible modular method is proposed to enable better and faster design. The structure module is set size inner-related, and then when the user requirements change, the key structural variables can be adjusted followed by the alterations of the driven sizes, also these alterations can be verified by the engineering analysis. Therefore, the product variant design process can be preceded effectively with the extensible modules.
