尽管各种生命周期需求对详细设计至关重要，但它们往往只是设计师头脑中的默契。本文试图开发一种正式的方法来捕获它们。由于详细设计主要涉及零件设计，因此首先介绍了如何对零件进行形式化描述。然后提出了零件功能的概念，用于描述零件详细设计时应考虑的各种生命周期因素。在此基础上提出了一种生命周期需求获取方法，其中零件功能与用于实现这些需求的几何特征或相邻空间相关联，从而可以从这些零件功能描述中获得各种生命周期约束。一个夹具设计案例说明了所建议的生命周期需求捕获方法。
Although various lifecycle requirements are critical for detailed design, they often merely remain as tacit knowledge in designers’ minds. This paper attempts to develop a formal approach for capturing them. Since detailed design primarily deals with part design, how to formally describe a part is introduced at first. A concept,part function, is then proposed for describing various lifecycle factors that should be considered for the detailed design of a part. A lifecycle requirements-capturing approach is then developed, where part functions are associated with the geometrical features or neighbor spaces used for achieving them so that various lifecycle constraints can be derived from those part function descriptions. A fixture design case illustrates the proposed lifecycle requirements-capturing approach.
