Abstract

Most of the design concepts available in the market come from the ideas of designers who sometimes have opinions that are contrary to the definition of custom design concepts and as a result, it is always confusing. The purpose of this research conducted is to improve the design of air freshener casing that meets customer demand by using Kansei Engineering. Kansei Engineering is a tool used to interpret human feelings and opinions from users or customers into design parameters. The result of this study is the design of the air freshener casing, which satisfies the psychological feelings of the customers. With reference to the main objectives in this research, three objectives have been proposed. First, to study Kansei engineering and Kano model in air freshener’s casing product design. The second objective was to analyse data using questionnaires by applying Kansei word embedding with the Kano model. The final objective of this study was to develop a 3D prototype of air freshener design using Kansei engineering (emotion) embedded with the Kano model (satisfaction). The Kansei survey consists of two parts. In the first part, a pre-survey was conducted to collect data on customer preferences for air freshener products available in the market. With reference to the highest scores from the survey for each question related to Kansei Engineering, it will be used in the main survey phase. A second survey was conducted to collect data on customer thought and opinions regarding the products selected in the presurvey. To analyze the results in the second survey, use the SPSS software to find correlations between the two variables. Successful results were obtained, by using morphological chat to construct 3 concept designs for the new design of the air freshener casing. The final product of the air fresheners causing was chosen using the Pugh method, which is a process for ranking the three concepts, with concept design no 2 receiving the highest score.
