概念设计中的设计过程知识获取研究

Acquisition Method of Design Process Knowledge in Conceptual Design

【目的】探究概念设计过程知识的获取方法,为设计过程知识的模块化建模和表示提供知识素材,进而实现动态设计过程知识的管理和重用。【方法】从知识内容角度对设计过程知识获取需求进行分析;结合访谈调查法和研究设计的双层流程获取模板对设计过程知识获取实验进行设计;采用访谈调查法初步获取组织内隐性的设计过程知识,利用双层流程获取模板进一步对设计过程知识进行模块化处理。【结果】以某制退机概念设计为例,采用访谈法获取初始设计过程知识;利用设计流程获取模板对设计流程知识进行整理和规范,利用设计步骤获取模板对规范后的设计流程知识进行拆解和封装。【局限】实验开展及结果数据处理都依靠人工方式,其效率有待提高。【结论】所提出的知识获取方法能够以模块化形式有效地获取概念设计中隐性、动态的设计过程知识。

[Objective] This paper proposes a new knowledge acquisition method for conceptual design process, aiming to improve the modular modeling and representation, as well as effectively manage and reuse dynamic knowledge. [Methods] First, we analyzed the design process knowledge acquisition from the perspective of content. Then, we designed a knowledge acquisition experiment with the help of interviews and the double-layer flow acquisition template. Finally, we obtained the implicit design process knowledge in organization by interviews, which was modularized by the double-layer flow acquisition template. [Results] We used the conceptual design process of a recoil brake part as case to retrieve the initial design process knowledge. The design flow knowledge, which was organized and normalized by acquisition template of the standardized design flow, was dismantled and packaged by acquisition template of the design step. [Limitations] Both the experiment and data analysis were conducted manually, which posed negative effects to the efficiency. [Conclusions] The proposed method could effectively obtain the tacit and dynamic design process knowledge from conceptual design.
