模块化的毛衫产品族设计及评价指标

Modularized product family design method of sweater and evaluation indexes

针对毛衫产品族设计中的模块划分规则不清晰、可操作性不强等问题,提出一种模块化的毛衫产品族设计方法。根据毛衫结构的特点,设计了模块划分规则:突出变型设计的方便性和产品族设计的通用性;将基于区域结构的横向模块、纵向模块与独立于区域结构的全身结构、装饰结构有效结合在一起,构成毛衫产品族的基本设计单元。另外,设计了一套模块化产品族设计的评价体系,根据多样性、通用性和新颖性3个指标计算出平均设计时间成本,并给出了评价指标与时间成本的关系、时间成本与企业收益之间的关系。验证结果表明,所设计模块化方法在不降低产品族通用性的同时,可提高产品族的新颖性,进一步提升产品族的多样性,从而降低设计时间与成本。

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 characteristics 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 module and vertical module are effectively combined 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 indexes 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.
