Modular design is an important elemental design technique in life cycle design. Modularity may increase maintainability, upgradability, and so on. Appropriate modular structure differs according to applied life cycle options; e.g., while the modular structure for recycling should be based on material kinds, the structure for upgrading should be based on functions to be obsolete. However, from the technical aspect, since most existing methods employ connectivity of components and do not use geometric information, they may derive unrealistic modular structure. For solving these problems, this paper proposes a modular design methodology that utilizes life cycle option, geometric model, and connectivity of components. The life cycle options classify the components into some groups that should trace the same life cycle and the geometric information and the connectivity are employed to derive a feasible module structure within the group. This paper also illustrates a case study using a printer. This case study reveals that the methodology derives geometrically consistent modular structures flexibly depending on life cycle options.
