目的 为消除儿童游泳时的恐水心理，助其更好地学习游泳，探索儿童游泳辅助产品的创新设计路径。方法 首先，采用实地问卷调查法提取儿童初学游泳的需求并在层次分析法(AHP)中筛选出最大权重项;其次，运用QFD建立“用户需求-设计要求”关系矩阵，将关键设计目标转化为主要功能;最后，在FBS模型中映射出功能对应的结构模块。结果 提出儿童游泳辅助产品以用户行为需求为导向的四大功能模块，即预警功能模块、学习功能模块、娱乐功能模块、调节功能模块，并以此为起点完成功能层-行为层-结构层的映射，从而指导游泳辅助产品的创新设计表现。结论 QFD-FBS相结合能够填补空白点，在游泳辅助产品创新开发领域具有较好的指导意义，提高了儿童学习游泳的满意度，为游泳辅助产品设计领域引入新思路。

The work aims to eliminate children's fear of water during swimming to help them learn to swim better, and explore the innovative design path of children's swimming auxiliary products. Firstly, the field questionnaire survey method was used to extract the needs of children beginners to learn swimming, and the maximum weight item was selected in the Analytic Hierarchy Process (AHP). Secondly, QFD was used to establish the "user needs-design requirements" relationship matrix, and the key design goals were transformed into main functions. Finally, the structural modules corresponding to the functions were mapped out in the FBS model. Four functional modules of children's swimming auxiliary products oriented by user behavior needs were proposed:early warning function module, learning function module, entertainment function module, adjustment function module, and the modules were used as a starting point to complete the mapping of function layer-behavior layer-structure layer and guide the innovative design expression of swimming auxiliary products. The QFD-FBS fusion model can complement the shortcomings of each other and has good guiding significance in the field of innovation and development of swimming auxiliary products, which improves the satisfaction of children in learning to swim and introduces new ideas for the design of swimming auxiliary products.
