Research On Functional Design Of Household Juicer Based On FAST

With the improvement of people’s life quality and consumer awareness,self-made green raw foods have gradually become people’s lifestyles.The demand for juicer products as kitchen food small household appliances is expanding,and its penetration rate is increasing year by year.The juicer products will have a great development prospect.In order to improve the design situation of single juicer and homogenization of household juicer,this paper analyzes the function of household juicer based on FAST functional analysis method.Finally,we design a multi-functional household juicer that is simple,stylish,easy to use,and meets the needs of users.This paper first conducts research on a variety of commercially available juicer products through market research,and analyzes the existing functions of the products.Then,based on questionnaires,user interviews and other research methods,the target user needs are investigated,collated,analyzed and summarized.The FAST functional structure model is constructed by combining FAST functional analysis methods,and the innovative functions that can be developed are obtained.Finally,the obtained functional scheme is embodied in the design of the household juicer.In the technical practice part,this paper studies and analyzes the principle of ultrasonic technology,and designs the centrifugal rotor and uses it for the experiment of cleaning device.By changing the power,frequency and cleaning time factor of the ultrasonic vibrator.Finally,the best operating parameters for the cleaning function are be determined.It provides design basis and guidance for design practice and prototype development.The functional design of household juicer based on FAST can not only effectively solve the current design situation of existing products,but also achieve the purpose of adapting products to market and technology by integrating product functions and utilizing existing functions or creating new functions.It also meets the development trend of future products.This innovative practice research has a certain complementary effect on the scope of applicability of FAST,and also has certain design reference value for other similar products.
