Abstract: This study discusses the conceptual design process based on kinematics characteristic and proposes how to analyze the feasible design scheme combinations on the basis of kinematics characteristic analysis. The possible kinematics characteristic of target scheme can be expressed by the possible typical form in the intermediate process from initial state to target state. The scheme solving process means the process in which function conversion element can generate the state of satisfying output. Function conversion generator, which relates to structural forms, can work out the overall scheme that meets design requirements through the combinational computation between mechanisms.
