Value Growth Design is a design based on a new design paradigm; Timeaxis Design; which incorporates the viewpoint of the time axis into the theory and methodology of design. Value Growth Design enables an object to increase in its practical value; such as its usability; and in its spiritual value; such as affection; the more it is used. This is antithetical to value decay design; seen in artifacts of mass production and mass consumption; which show a decrease in value over time. If such artifacts were able to adapt to the change of environment and the change of value based on the theory of Timeaxis Design; it is expected that their practical values and spiritual values would increase. This can enable artifacts to become appealing to human Kansei and allow users to possess a single artifact over a long range of time with strong affection. However; there are only few studies which have considered the application of Value Growth Design to actual design. Thus; in this research; a case study of existing value growing cases is carried out; followed by a cluster analysis and a discussion of the results which produce nine factors of value growth.
