Abstract

Consumer’s preferences and market demand are essential factors for product’s success. Thus, in achieving its success, a product should have design that could fulfill consumer’s expectation. Based on the issues, the purpose of this research is to accomplish electric kettle product as stipulated by Kansei. Using the Kansei Engineering concept, this study was carried out to improve the design of an electric kettle in order to help satisfy the needs of consumers. Kansei Engineering was used to capture and translate the elements of design into consumer perception known as Kansei words. The dominant Kansei words that influence customer satisfaction will become design priorities in the future product development. Three main goal for this study and research, are to study the customer preferences towards the product design and characteristic using Kansei Engineering tools and Kano model, to investigate the customer requirement of product based on customer feeling and emotions to the characteristic of electric kettle product embedded with Kano model and to develop 3D prototype of electric kettle based on customer preferences using Kansei Engineering Method (emotion) embedded with Kano model (Satisfaction). The goal of this study may be accomplished by using a questionnaire survey to collect consumer data. Questionnaires 1 and 2 will be used in this study, which will include a total of 100 participants. SPSS statistical software will be used to analyze the data collected. The Pearson correlation will be applied to analyze the correlation between the Kansei for design attributes and Kano for product functionality. The result of this research founds that Kansei words represent customer’s desire in designing electric kettle; safe, lightweight, durable, and simple while electric kettle’s functional requirements; easy maintenance, easy operated, boil dry protection, automatic shutoff, easy operated, concealed element, and part touch water non-plastic. The Pearson correlation was used to analyze the elements that customers require in an electric kettle. Based on the study's goal, a Pearson correlation analysis was performed between the Kansei word and the Kano questionnaire of the design profile. Overall, there is a high correlation between kansei words and the design of the electric kettle which indicates that if we design an electric kettle with all of the Kansei words, the new design of the electric kettle will meet the needs of the customer. However, the correlation of Kano and Kansei reveals a weak negative association, indicating that the existing market for electric kettles is relatively satisfied, since there is no need for considerable increase in functionality. Afterwards, the outcomes will be represented using Kansei words acquired from a questionnaire survey and analysed data derived from customer input using Pearson's correlation. All Kansei words that have passed all validation methods will be transformed into a final design of electric kettle that meets the needs of the customer.
