Research On Innovative Design Of Air Purifier Based On TRIZ Theory

The existing air purifier market competition is fierce,product simplification and homogenization phenomenon is serious,single function air purification products have lagged behind the requirements of the times,can not better meet the needs of users.Therefore,it is urgent to design innovative air purifiers that meet the market demand and have forward-looking features.In this paper,after a full investigation of the market,combing the characteristics of user demand,using TRIZ theory of technology system evolution to verify the rationality of characteristic demand,innovative design of a multi-functional air purifier,after trial production found that there is a problem of noise,then use TRIZ theory to analyze the problem and solve the related problems,obtained the multi-functional air purifier At the same time,a product innovation design method model is constructed in the research process,which innovates the product design process and broadens the ideas for the relevant R &D personnel.The main contents are as follows:1? User requirements feature acquisition and classification.Through the network e-commerce platform,the competitive products of top ten brands of air purifiers are analyzed,and the appearance,color,function,performance and other parameters of air purifiers in the existing market are obtained.Combined with the investigation and analysis of the advantages and disadvantages of the fresh air system,the initial user demand is obtained.The user characteristics of air purifiers are classified and analyzed by using Carnot model,and the user demand of existing products is explored In this paper,we use the nine screen method to further study the product and system,and use the evolution law of technology system to verify the excited demand,and obtain the forward-looking excited demand items of users.Meanwhile,we will make three stages of development forecast for the future development trend of air purifier industry.This article is mainly aimed at the first stage of the study.The second phase of the study is the Sixth China Internet plus gold medal / Guizhou bronze medal.2? Customer demand restructuring and innovative product design.After obtaining the end-user requirements,the functional design model of the air purifier is obtained by transforming the user requirements into the product engineering design technology of the corresponding air purifier;the appearance design and structural design of the air purifier are carried out to obtain the product design scheme,and a multi-functional air purifier with air disinfection,air purification and indoor oxygen supply is designed and manufactured The carburetor.3? Optimization design of multifunctional air purifier.There is a big noise problem in the trial production of multi-functional air purifier.This paper analyzes the noise source of the product,analyzes and optimizes the air purifier by using the contradiction rectangle of TRIZ theory,s-f field principle and other tools,optimizes the interactive interface,obtains a new design scheme,and designs air purification products that meet the needs of consumers and lead the future market.At the same time,based on this product,a multi space indoor air purification solution is proposed,which integrates air disinfection,air purification and oxygen generation into a multi-mode group air purification system,ushering in a "new revolution" of indoor air governance for the air purification industry.
