Abstract

Consumer tastes and market demand are critical elements in the success of a product. As a result, in order to be successful, a product must have a design that meets the expectations of consumers. The goal of this study is to create an air diffuser product inspired by Kansei. Using the Kansei Engineering approach, this analysis was undertaken to improve the design of an air diffuser in order to better suit the demands of the consumers. Kansei Engineering was known for capturing and translating client perceptions into design elements (Kansei words). This study and research has three major objectives: to investigate consumer preferences for product design and characteristics of air diffusers, and to develop new air diffuser designs in 3D modelling based on those choices. The goal of this study may be accomplished by using a questionnaire survey to collect customer data. Questionnaires 1 and 2 will be used in this study, which will include a total of 100 participants. Questionnaire 1 is used to gather information on the types and designs that customers want, while Question 2 is used to determine how respondents feel about the link between kansei terms and design categories. One issue for product development in this setting is capturing consumer product expectations and translating these subjective components into real product design. As a result, Kansei Engineering tools were utilised in this study to classify and categorise Kansei terms from consumer perception into characteristics, which helped with computation and statistical analysis. The Kano method is used in questionnaire 2. The Kano model is helpful in acquiring a comprehensive grasp of a customer's requirements. SPSS Data analysis software has been used to analyze the collected data. The findings show that the majority of consumers prefer air diffusers that are eye-catching, modern, attractive, and trendy. The Pearson correlation was applied to analyze the factors that consumers need in the air diffuser. The Pearson correlation analysis was carried out based on the study's purpose, and it was between the Kansei word and the Kano questionnaire of the design profile. Overall, the correlation between kansei words and the design of the air diffuser is high. It means if we produce a product like an air diffuser with all the Kansei words, the new design of the air diffuser will attract more buyers. Moreover, the correlation between kano and the design of the air diffuser is only positive for Design A and Design D. In the conclusion, the results will be represented by Kansei words obtained through a questionnaire survey and the analyzed data gathered from consumer input utilizing Pearson's correlation. Based on the Pearson's correlation, all Kansei words that have passed all validation procedures will be turned into a final design of air diffuser that satisfies the customer's demands. At the conclusion of this study, the results of the new air diffuser design will be represented by Kansei words obtained through a questionnaire survey and the analysed data gathered from consumer input utilising Kansei Engineering tools. Based on the emotional component of Kansei Engineering, all Kansei words that have passed all validation procedures will be turned into a final design of air diffuser that satisfies the customer's demands.
