Method to build a generalized table of parameters in engineering design of technical systems: Lattice structure as a case study

Abstract

Design parameters are a crucial element of the product design process. However, design parameter models are often used to solve specific design problems. Generalizing design parameters is an approach to tackle more design problems. This study contributes to resolving certain limitations associated with modeling and representing the design parameters. This paper presents a generalized table of parameters (GTP) for modeling system parameters. This table is linked to a contextual database based on data and information collected from scientific databases, experts' interviews, and Computer-Aided Design (CAD) and Finite Element Modeling (FEM) software analysis and usage. The proposed representative table shows the robustness of integrating multiple sources of information to present a holistic and generalized view of the design system. The quality of the provided data in the table is assessed by applying certain evaluating dimensions and indicators. A case study will be presented on the lattice structure within a specific context in the mechanical field.
