Design Analysis of Sit-up Booster Based on KANO Model

Abstract: Purpose: With the advent of the Industry 4.0 era, technology's continuous development and progress. Working and studying in a fixed posture for a long time has become a regular part of people's lives. The resulting diseases such as lumbar disc protrusion, lumbar strain, and scoliosis increase yearly. The age of patients is also showing a trend of low generation. At the same time, the elderly and pregnant women occupy a large proportion of them. Most of the products on the market for lumbar problems are still lumbar massagers, lumbar pillows, and other products used to relieve lumbar pain. They still do not solve the inconvenience of daily life caused by lumbar diseases. In response to the problems mentioned earlier, the sit-up booster can provide adequate assistance to patients as an additional indoor product. Through external support and the appropriate amount of external force to give users a certain amount of support in the process of rising and setting, to reduce the discomfort in the process of rising and sitting.Methodology: As a product that improves the life of users and enhances the quality of life of users, it is necessary to follow the "people-oriented" design concept in the design and put the user experience in the first place. Therefore, we conducted market research and user research to analyze the existing products to discover their shortcomings. Then, through user interviews and user journeys, we summarized the problems in users' lives and the problems they encountered with existing products. Conclusion and concluded the product design that derives elements that can improve user experience, designed questionnaires, and analyzed the results using the KANO model to derive the most real pain points of users.Result: According to the information obtained from the fuzzy front-end research, the design practice of the sit-up booster was carried out by continuously improving the details to make the connection between the user and the product closer. While solving the pain points, the product can be applied to more people, regardless of age, gender, and other restrictions.Conclusion: This design study addresses the growing number of people with back discomfort in today's society and finds that they need to improve and enhance their needs in life. The design of a sit-up booster emerges as a general trend. Use the KANO model to analyze the preliminary research results and get the critical needs of users for the product. According to the user's requirements for different functions, the user's needs are ranked, and then the aspects that need to be considered a priority, and the booster is designed for these aspects. It provides a direction for the future design of the sit-up booster.
