Design Function Matrix (DFM) to identify modules for product architectures at the conceptual design phase

The Design Function Matrix (DFM) offers a comprehensive approach to modular design in product development. It integrates a structured methodology for analyzing and identifying modular components during the early stages of design, highlighting the importance of modularity for efficiency and lifecycle cost reduction. The DFM framework focuses on functional analysis, particularly the interactions of Material, Energy, and Signal flows. By mapping these flow interactions within a matrix structure, the DFM provides a clear visualization of the system's architecture, enabling designers to easily identify potential modules. The research further delves into the quantification of these interactions, which plays a crucial role in the modularization process. This aspect of the study is exemplified through various case studies, demonstrating the practical application and effectiveness of the DFM in real-world scenarios. The matrix's classification system is particularly noteworthy for its ability to systematically map all possible flow interactions, thus facilitating a more streamlined and efficient design process. Overall, the DFM stands out as a significant contribution to the field of product design, particularly in its potential to revolutionize the way modular components are identified and integrated during the conceptual design phase.
