Product design for energy reduction in concurrent engineering: an inverted pyramid approach

Abstract

The consideration of energy aspects as X in the design for X (DFX) paradigm in concurrent engineering (CE) is important for enabling reductions in operating costs, reducing greenhouse gas (GHG) emissions and enhancing sustainability. This research presents a CE methodology for the consideration of energy use in product development and manufacturing, specifically addressing the machining process. The research reported in this paper showcases the effectiveness of using a systematic integrated approach towards consideration of energy in product development, addressed through product, process, and system level parameters. It adds an important tool to the DFX toolbox for evaluation of the impact of design decisions on the product manufacturing energy requirement early during the design phases. The use of the inverted pyramid approach (IPA) has been described as an effective methodology for incorporation in expansion of the DFX toolbox.
