Abstract

Many people feel cleaning bathtub is a great deal of housework today. Moreover, it is dangerous especially for elderly people to clean a bathtub since they may be injured by slipping on the bathroom floor. However, Japan is a most aged society in the world, so that elderly people have to do housework in many Japanese household. On the other hand, an understanding customer requirement is most important for a conceptual design. Successful companies are providing the highest quality service by which customer receives a satisfaction through the Kando experience. Thus, an element of customer satisfaction is necessary for the great success in business. Therefore, authors have proposed the Idea Creation Support System (ICSS). In this paper, we develop a robot cleans a bathtub automtically by using ICSS. At first, we discussed a concept of the bathtub cleaning robot based on questionnaires and the patents search about existing bathtub cleaning machines. Next, the first prototype of the bathtub cleaning robot was developed and could clean a bathtub through the experiment for validation. Based on validation of this prototype, we tried to define concept by ICSS again. In the ICSS, words of the Kando quality were gotten by world cafe. Moreover, we calculated demand quality weight and quality element weight calculated through Quality Function Deployment. Thereby, we drew on quality elements for the bathtub cleaning robot.
