Research On Innovative Design Of Multifunctional Desks And Chairs Based On Ethnography Theory

Today,mainstream culture and subculture are intertwined and thriving,user needs become more personalized,and product divisions on the market are more detailed.Faced with the development of new products of different groups of people,higher requirements are placed on precision-cutting user needs.The satisfaction of design requirements for user needs has become the focus of attention,and active user demand mining has become the mainstream choice for all companies.This article begins with the research method of group culture,from the discovery of breakthrough requirements and the precise construction of user demand models,and combines a systematic design,optimization design,process simulation and other modern design process methods and technologies to propose a specific process of product innovation design.First of all,this paper starts from the field study of the group culture study of the research object,grabs a large number of original user needs,uses the KJ method to extract and screen,formulates the user needs research questionnaire,and uses the crowd data clustering analysis based on the big data cloud framework to select the sample.Survey sample population;user group analysis of the recall questionnaire,select the most representative population,and build a user demand feature model based on the cultural characteristics of the group.Secondly,based on the sample product's functional principle analysis,appearance modeling analysis and value analysis,this article draws on the advantages of the sample product,carries out the innovative design of the multifunctional desk and chair function principle plan,and obtains a large number of feasible plans in the form of morphology matrix.Application of Quantitative Theory I Construct mathematical models for relationship between evaluation indicators and functional and functional element solutions for innovative solutions.On this basis,prepare M files and use MATLAB software to run the program for program optimization.Pass through the value profile of the three preferred solutions.The graphs are analyzed for features to determine the optimal design.Finally,with the help of design software Creo and rendering software keyshot,the optimal design of multi-functional desks and chairs is modeled in 3D and appearance effects are expressed,and the story version is used to simulate the process of listening and fitness.The comprehensive evaluation of the degree of satisfaction verified that the specific product design process explored in this paper is feasible and effective.
