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。

Abstract: 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.
