Abstract
The circumstances of artifacts have changed in recent years. Artifacts must be designed to reduce the environmental impact due to the deteriorating environment. Additionally, due to globalization and the uniformity of culture, artifacts must meet diverse definitions of value which change as time goes by. Therefore, the way of design needs to adopt the viewpoint of time. Value Growth Design enables artifacts to increase its value over time, and is based on a new design paradigm, Timeaxis Design. Timeaxis Design incorporates the viewpoint of time into the theory and methodology of design. However, only a few works have considered the application of Value Growth Design to actual artifacts. Herein, we investigate existing Value Growth Design cases, and employ cluster analysis to extract the features of Value Growth Design. The case studies revealed that there exist several patterns throughout an artifact's lifetime, suggesting that a detailed investigation may lead to the application of Value Growth Design.
