Abstract:
Engineering design can be seen as a problem solving process in which engineers and designers convert their thoughts and ideas into real-life designs satisfying market and customer needs. The conceptual design process is crucial in engineering product design since it determines fundamental design features with respect to design requirements. Any decisions made at this stage have a significant impact on later stages of design. However, connection between system functional requirements and selection of actual mechanical components in mechanism designs is severely lacking. With the purpose filling this gap and assisting engineers and designers to obtain in-depth understanding on commonly seen mechanisms and machine elements a database (MMET) was established and programmed containing detail information of these components including technical functional attributes, movement attributes, pictures/drawings and merit analysis. A conceptual design tool built on MMET was then developed aiming to help the user to explore a broad range of mechanical components regarding system requirements. The database and conceptual design tool were validated and improved through industrial case studies which suggest the addition of Function Means tree and Functional Analysis Diagram. The value of MMET and the new conceptual design tool are indicated via positive outcomes of case studies, asserting their capability of offering assistance in understanding engineering product functions and how these functions are achieved, enabling comparisons regarding same functional requirements and finally providing opportunities for conceptual design improvements based on a cyclic process containing detail functional analysis, function-means tree construction and design optimisation.
