Creating a functional model for conceptual design

The goal of this study is creating a functional model by using functional basis tool which is the most critical stage of the conceptual design. Nowadays designers are missing the design stages due to lack of information about the design processes in industrial applications. This case can affect the design efficiency and design time negatively. Since the functional basis lets the systematic design stages, it prevents the needed individual experiences and capabilities for design. This study is prepared for supporting a functional model for mechanical or machine designers and related departments in conceptual design processes. Function and flow classes are also discussed here to create a functional model. Furthermore a functional model structure, which is an intangible concept, is supported with verified examples. As a result, the applicability is proved of the functional model structure. Key Words : Conceptual design, Functional modeling, Functional basis
