为了设计知识重用,提出一种通过分类、索引获取产品外观设计知识的方法。根据产品外观在传播系统中的性质,建立对象和实现性两类产品外观设计知识基本类型。基于分类学原理,根据用户认知过程和设计师造型过程,对产品外观知识的基本类型进行分解,形成可以细致描述和规范案例的外观知识框架。知识框架包括功能、形式、使用方式、文化时尚、设计过程、创新方法、形式方法和制造工艺8种类型,可以应用于建立产品外观案例库,分解产品外观。在造型过程中,设计师搜索图像信息阶段和发展形态阶段,案例库对灵活重用设计知识有着促进作用。最后,对设计师使用外观案例库进行手机设计的情况进行观察,统计使用情况和方案设计质量的关系,调查结果反映该方法存在应用价值。
A method to classify and index product design form knowledge is developed to support the reuse of design knowledge. According to the properties of product form in the broadcasting system, form design knowledge is built on the structure of object type and realization type. Based on the principle of taxonomy, the users' cognition process and the process of form-creation, design knowledge basic types are decomposed to set up the design form knowledge frameworks, which can describal formalize the cases. The knowledge frameworks include 8 types, namely function, shape, use, cultural fashion, design process, innovation method, formal method, manufacture craft, which are applied in the product cases database to decompose form. The product cases database can promote the designers to reuse the design knowledge flexibly when they search for the image information and develop the form. Finally, the situation of designers designing the mobile phone with the cases database is observed, the using situation and the quality of solutions are calculated, and the result reflects the method's application value.
