Most conventional industrial product's value is at its maximum at the time of purchase, and starts decreasing until its disposal. Therefore, the lifecycle of products tend to be short, which leads to mass production and mass consumption harming the environment. In order to face this issue, a methodology, which aims to increase products value, is proposed as the Value Growth Design. In a previous study, we proposed the concept of Value Growth Mobility that has two basic systems: a Core Module System and a Service System. This paper describes the development of a Service System supporting mobility's value growth. To develop the Service System, a system development method integrating the Multispace Design Method and System Modeling Language (SysML) is used. The Multispace Design Method is a design method based on a Multispace Design Model that can describe various behaviors of design from the common perspective. SysML is a modeling language that supports a development of the large-scale and complicated system by diagram description. By applying the method integrating the Multispace Design Method and SysML, a new Service System that considers psychological elements including sense of attachment and intimacy that the user gains toward the vehicle is proposed. Additionally, the design of subsystems to realize this Service System is discussed.
