目的 提出产品设计中的虚空间概念，为设计师提供一个认识产品设计的全新角度，以帮助设计师更好的开发产品。方法 以产品虚空间为研究对象，通过分析产品设计中虚空间的概念、存在形式和设计意义，提出虚空间的 4 种设计方法，即空间分割法、空间加减法、空间共享法与空间借用法。结论 设计师在进行产品设计时应重视虚空间概念，以虚空间为研究对象，通过设计其他事物间接完成对虚空间的功能设计。

Creatively put forward the concept of void space in product design to provide a new understanding of product design perspective for designers and better help designers develop products. Regarding void space of products as the research object, it analyzes the concept , the existence form and meaning of void space in product design, put forward four kinds of design method about void space: spatial partition method, spatial subtraction method , spatial sharing method and spatial utilizing method. Through the analysis of the four kinds of design methods, we draw a basic conclusion about void space design: when designers design products, we could pay attention to the concept of void space and treat void space as the design object and complete the functional design of a void space indirectly through the design of other things.
