Abstract:

In view that the rules of module partition are less clear and some are not so feasible in the product family design of sweater, a modularized product family design method of sweater is proposed. According to the structural characters of sweater, module partition rules are designed, which emphasize on the convenience of variant design and the generality of product family. Body regional structure-based horizontal modular and vertical modular are effectively combining with the whole structure and the decorative structure which is independent from the regional structure to constitute the basic design unit of the sweater product family. Furthermore, evaluation indexes of the modularized product family are designed, through which the average time cost of design is calculated according to the three indicators including diversity, universality and novelty. At the same time, the relationships of evaluation indexes and time cost, and time cost and enterprise profit are given. Experimental verification shows that the proposed modularization method can improve the novelty and diversity while without reducing the universality of the product family, so as to achieve the purpose of reducing the design time cost.

Key words: module partition, product family design, evaluation index, mass customization
