模块化设计可以构造出许多符合客户需求的各种产品 ,并且能降低产品的成本。本文首先分析公理性设计方法 ,在其基础上提出了基于信息依赖的设计结构矩阵进行模块化的协调设计。两种方法的综合应用 ,使设计者不仅能从不同的域认识产品的结构 ,而且也能通过单独的一个域描述产品 ,使产生的模块更加合理并提高设计质量 Modular design can create a variety of products that meet the needs of customers, and can reduce the cost of the product. This article first analyzes the axiomatic design method, and on the basis of it, puts forward a modular coordinated design based on the design matrix of information dependence. The combination of the two approaches enables designers to not only understand the structure of a product from different domains but also to describe the product in a single domain to make the resulting module more rational and to improve the quality of the design
