摘　　要：针对上颌前方牵引矫治器在使用过程中出现的舒适度低、佩戴不便等问题,提出基于功能分析(FA)和发明问题解决理论(TRIZ)相结合的集成设计方法。通过对上颌前方牵引矫治器的功能分析,建立功能、结构部件之间的关系,形成部件交互矩阵。应用TRIZ理论分析产生交互作用的部件与子功能之间的关系,形成功能-物场模型,并根据模型实际效用划分其所属类别,利用76个标准解寻找对应解决方法,获得上颌前方牵引矫治器改良设计方案。利用有限元分析法(FEA)赋予相应的材质和作用力,建立对比实验对方案进行评价分析。最终,以上颌前方牵引矫治器的创新设计方案实施为例,验证了该集成方法以及评价方法的可行性。Aimed at solving such problems as discomfort and inconvenience of the maxillary anterior traction appliance, an innovative design method based on FA and TRIZ was proposed. The relationship and the component interaction matrix between the functions and structures were established based on the FA. The TRIZ was adopted to analyze the connections between the interacted components and sub-functions, thus forming the function-field model. Its categories were divided based on the actual utility. Then 76 standard solutions were employed to address problems, thereby obtaining an improved design of appliance. Finite element analysis was made to evaluate the redesign scheme by giving the materials and forces. A comparative experiment was undertaken to evaluate the redesign scheme. Finally, the feasibility of the FA/TRIZ integration method and evaluation method was verified through the implementation of the innovative design of the maxillary anterior traction appliance.
