中文摘要：

为了针对产品创新设计中的矛盾问题寻求最佳设计方案,提出一种可拓设计理论方法,该方法集理论、实践、科学、哲学和方法论为一体,具有设计目标清晰、冲突消解过程有序、方案输出结果满意等特点。通过分析比较发明问题解决理论、基于规则/实例推理、约束松弛、协商、回溯、可拓设计等常用于产品创新设计过程中的冲突问题消解方法,论述了可拓设计方法最大的特色在于模型化、形式化、定性与定量相结合,是一种智能化处理设计对象、设计系统的现代设计方法;系统介绍了可拓学和可拓设计的形成及相互关系、可拓设计的研究方法和设计原理,对可拓设计各步骤环节的研究现状进行了综述,论述了目前存在的不足及今后的发展方向与思路;阐述了可拓设计方法及其计算机实现的策略生成系统,对几种典型的可拓设计软件系统做了简要介绍;最后对全文进行总结,展望了今后的研究目标及需要解决的研究难点。

英文摘要：

To find the best program for solvi.g contradiction in product innovation design, an extension design method was proposed, which had features of clear design goal, orderly conflict resolution process, satisfactory output program in prod- uct innovation design application. Through the analysis and comparison of common conflict resolution methods in innovative product design such as Theory of Inventive Problem Solving （TRIZ）, rule/case-based reasoning, constraint loosening, ne- gotiation, backtrackiing and extension design, the extension design method was chiefly characterized by its formalization, modeling and combination of qualitative and quantitative. It was a modem design method that intelligently processed design objects, design systems and design processes. The formation of extenlcs and extension design, their relationship, the re- search methods and design principles of extension design were systematically introduced. The research status of various steps and links in extension design was summarized. The current deficiencies as well as future directions and ideas of exten- sion design were discussed. Extension design methods and the strategy generating systems for their computer implementa- tion were explained. A brief introduction was given to several typical software systems for extension design, and the pro- spective research objectives as well as difficulties were forecasted.
