Design of Car Child Safety Seat Based on Analytic Hierarchy Process

Abstract

This paper analyzes the existing problems of car children’s safety seats at present, looks for the space of product design innovation, and designs products that meet the needs of private car owners and meet the trend of the times from the angle of shape and function. Through the analysis of the characteristics of common brands of child safety seats in the market, the design elements are found and the measures layer of product design is constructed; By searching the existing literature on car child safety seats and questionnaire survey, the characteristic index of products is obtained, and the design criterion layer is constructed Analytic hierarchy process (AHP) is applied to calculate the weights of indexes at different levels and sort them to determine the design opportunities of products. Through an example of car child safety seat design, it is proved that AHP can quickly obtain the demand points of product upgrading and innovation, determine the design opportunities of products, help designers to improve product design efficiency, and promote the healthy development of car child safety seat industry.
