目的 探索基于产品设计系统思维的家电产品模块化设计思路。方法 模块划分是产品模块化设计的基础与关键，可看作是基于需求层、功能层、结构层的过程而进行，该过程注重对产品功能属性的塑造而缺乏审美精神属性的把握。基于产品设计系统思维，结合多种形式及放置方式的移动插线板模块化设计实例，将产品设计系统之设计要素映射于模块划分的不同层次，从设计系统的角度对家电产品模块划分进程给予指引与限定，使设计结果兼具人文精神内涵。结论 从设计系统角度进行家电产品模块化设计，其设计结果兼具了产品的功能与精神双重属性，既发挥了模块化的自身优势，又补充了模块化设计在人文精神表达上的缺憾。

It aims to explore the modular design of household appliances guided by system thinking of product design. Module division is the foundation of product modular design. The context of module division can be explained as the process based on demand layer, function layer and structure layer which focuses on product's functional properties and lacks the aesthetic spirit connotation. Therefore, based on system thinking of product design, integrating the modular design of a multi placement mobile socket, mapping the design elements of product design system to different layers of module division to guide modularization process from design angle and make the design result has aesthetic spirit connotation. Result of household appliances modular design based on design system has both the function and the spirit attributes. This not only plays modularization' advantage, but also is a kind of product modular design which roots in design soil.
