Abstract:

In order to reuse all kinds of part resources effectively during product variant design, process modeling of mechanical product variant design was proposed from the aspect of design activity, and the modeling framework of variant design process was also presented. Firstly, the variant modes of different types of parts were analyzed based on the part classification on the context of mass customization. The dimension constraint network among mating parts was constructed at the parameter level of part. And then, variant design activity was defined with triple elements. Based on these,a logical structure model of variant design activity was established. Secondly, the rules of product variant design process configuration were identified from the aspects of activity and part respectively. As a result, variant design process of different customized product can be derived with the goal of reusing different types of part resources. Finally, an example was given to verify these methods and principles mentioned above.

Key words: variant design activity, logic structure, complexity, process configuration of variant design
