Research on Integrated Cooker Design Based on EGM-AHP Method
Objective:The purpose of the paper is to accurately understand the needs of integrated cooker users,and to improve user satisfaction.Methods:Firstly,the evaluation grid method(EGM)is introduced to conduct in-depth interviews with users to obtain multiple needs for integrated cookers.Secondly,these needs are integrated,screened and supplemented by KJ method,and are categorized into basic functions,appearance forms and intelligent interactions,and the evaluation structure diagram is drawn accordingly.Then,using the expert scoring method,interview method and AHP method,the hierarchical requirement index model is constructed,and the weight of each requirement index is calculated,which finally guides the design practice.Results:The integrated cooker design scheme based on the EGM-AHP method obtains higher satisfaction in the user research.Conclusion:The results show that the EGM-AHP method can help understand user needs and achieve innovative design of integrated cookers,so as to improve user satisfaction.
