| In the background of consumption upgrading,health,safety and comfort of bra Were concerned by consumers,Which have been the key factor of innovation and propaganda..However,the current situation of bra market is that enterprises have not been able to achieve the goal of "more comfortable" in product research and development,while many consumers have considerable uncertainty in their Perception and experience of comfort.The study focused on the problem of bra comfort,aiming at the Less innovation and comfort of bra,to explore the ideas and solutions To the improved design and consumption upgrading.The thesis study from the following three aspects:First of all,based on the subjective feeling of bra comfort,a questionnaire survey about perception and experience of comfort was carried out,to understanding,the consumers’ feelings and main demands for bra comfort,so as to implement the "pain point" of consumers in the design.Secondly,according to the characteristics of increasingly fine differentiation of bra products,The study utilizes the analysis of the differences and characteristics of bra functionality,the products in the market are classified and studied,and the bra is divided into 10 types by cluster analysis as the comfort differences of different functional types were analyzed on the basis of bra classification,and the comfort of different functional types is quantified.the were is established The fitness evaluation model provides a basis for the comfort design of bra products with different functional requirements.Thirdly,according to the objective analysis method of bra comfort,i.e.the stress on the chest when wearing,by summarizing the research results of bra comfort in mechanics,this paper puts forward a method of the stress characteristics of the chest under different dressing forms starting from the division of the chest form,and constructs six stress models,and accordingly puts forward the structural optimization method of bra design,So that the comfort design and experience of bra were more feasible and reasonable.In conclusion,this paper explored a new method of bra stress analysis,a comfort evaluation standard based on product classification and a series of knowledge about comfort experience.On this basis,the principle of perceptual engineering,aiming at the common phenomenon that consumers lack of understanding and experience of bra comfort,an intelligent bra assistant shopping guide system was proposed,which can recommend suitable product styles and sizes according to the individual characteristics and specific needs of consumers.The system adopts the operation mode of manmachine dialogue to improve.It can be applied in bra marketing,customization,consumer survey and demand analysis,product development,etc.This paper is divided into seven chapters,which were specifically,Introduction;Investigation and Analysis of bra consumption behavior and comfort cognition;Research on bra comfort based on product differentiation;Research on bra comfort model based on stress analysis;Development of bra assistant shopping guide system;Conclusion and Prospect. |
