A Function Combined Children Bike Based on Design of FAST Method

Through researching FAST(Function Analysis System Technique) method in Product Design,this method is completely applied to a Multi-function Children Bike design.Firstly,the FAST functional tree is set up by output of Black Box Model's information when children riding,and a series of probable design factors of children bike are obtained.Secondly,the Form Matrix of children bike is established with function combination,man-machine relationship and so on.Finally,a tentative tread-swing bike is designed in dectail,and a perfect effect drawing is obtained through 3D modeling,rendering and engineering output,and also,the man-machine relationship of this projact is analyzed.Therefore,a conclusion can be drausn that,on the one hand,the design result verifies the rational application of FAST method in product design;on the other hand,children's requirement for bike is no longer only on the concept of bike,but the multi-function including,function combined and function transform.
