摘　　要：针对可拓设计方法中第三创造法对现有产品模型的建立以及缺点列举中的不足,提出建立产品事元模型,并引入功能分析与因果链分析方法的改进第三创造法。该方法利用功能分析方法对产品的缺点进行分析,并通过因果链分析方法找出引起产品缺点的深层原因,以形成关键问题,最后运用第三创造法对关键问题的改进,得到产品创新设计方案。应用改进后的第三创造法,对现有普通断线钳进行创新设计并生成了多种不同的设计方案,对这些方案进行优度评价,选取优度最高者作为最终设计。设计结果验证了该方法的可行性和有效性。Due to the deficiency of product modeling and defect listing in the third creation method,a modified third creation method of Extenics was proposed using the affair model,and the functional analysis and cause-effect chain analysis were introduced. The product defects were found by functional analysis and the underlying cause can be determined by the cause-effect chain analysis. Then, the key defects were determined. Finally, the defects were resolved using the modified third creation method and a new product was formed with many design schemes. Also, new bolt cutters were designed by selecting the optimum scheme,and they proved the feasibility and effectiveness of the method.
