This paper introduces a method to improve the design procedure of axiomatic design theory (AD) with Extenics. A comprehensive review of the AD indicates that the powerful principle of AD has been widely studied and applied to many areas, however, inexperienced practitioners of the AD theory still find it difficult to follow or apply the principles in their design which inadvertently often leads to misunderstanding and skepticism. The lack of definitive descriptions for all the elements and specific approaches to guiding the mapping process restricts the development and application of AD theory. This paper improves the design procedure of AD with Extenics. The elements in AD domain are expressed by basic-elements of Extenics, and the formulations are generated. The mapping process based on AD and Extenics is developed. The improved design procedure provides designers with a theoretical foundation based on the logical and rational thought process, meanwhile the solution space can be expanded and innovative designs are inspired. Based on the proposed design procedure, a computer-aided system is developed, which makes the complex and fuzzy design activity clear and easy to follow by filling in the blanks in a step-by-step manner. An example of a novel corn harvester header design scheme is considered to illustrate the validity of the improved design procedure.

本文介绍了一种利用可拓学改进公理设计理论 (AD) 设计程序的方法。对 AD 的全面回顾表明，AD 的强大原理已被广泛研究并应用于许多领域，但是，缺乏经验的 AD 理论从业者仍然难以在设计中遵循或应用这些原理，从而不经意间常常导致误解和怀疑。缺乏对所有要素的明确描述和指导映射过程的具体方法限制了 AD 理论的发展和应用。本文利用 Extenics 改进了 AD 的设计程序。AD域中的元素用可拓学的基本元素表示，并生成公式。开发了基于 AD 和 Extenics 的映射过程。改进的设计程序为设计人员提供了基于逻辑和理性思维过程的理论基础，同时可以扩展解决方案空间并激发创新设计。基于所提出的设计程序，开发了一个计算机辅助系统，通过逐步填充空白的方式，使复杂而模糊的设计活动变得清晰易懂。一个新的玉米收割机割台设计方案的例子被认为是说明改进设计程序的有效性。通过逐步填空，使复杂而模糊的设计活动变得清晰易懂。一个新的玉米收割机割台设计方案的例子被认为是说明改进设计程序的有效性。通过逐步填空，使复杂而模糊的设计活动变得清晰易懂。一个新的玉米收割机割台设计方案的例子被认为是说明改进设计程序的有效性。
