In this paper, the method for establishing efficient and smooth communication system among designers is proposed through systematizing functions expansion on mechanical design. Module design is the main stream on current mechanical design. Modules are classified by functions. First, the process of function expansion is systematized by using 3 factors, object, action, and condition. Then the mechanism for showing relations to function unites is established. Second, the system for efficient and smooth communication among designers is proposed by developing designers support system using above-mentioned mechanism.
