An interactive system framework to enable design for disassembly

Abstract

Purpose The purpose of this paper is to present an interactive system to enable product design for disassembly and to offer robust and quick design solutions based on designers’ input. Design/methodology/approach The system utilizes an interactive questionnaire to communicate with the designer. The questionnaire is in the form of binary questions (Yes/No) and design questions that would enable the system to learn the objectives of the design. Solutions are based on a CAD supported design platform. The efficiency of each design is calculated using disassembly time as the metric of measurement using motion-time measurement (MTM). The designer would be able to make an informed decision with respect to component functionality, ease of disassembly and disassembly time. The paper presents a detailed framework and structure of this system. Findings The value of the system is corroborated by means of a case study of an actual product design. The system is structured to offer multiple solutions to a design problem so as to enable the designer to choose the option that best serves their needs. Originality/value This novel interactive system would accept customers’ design preferences as input and offer multiple solutions in order to solve the design problem. Process time is directly calculated using the MTM system of measurement by converting design features into time measurement units. Disassembly time can then be easily converted into disassembly cost by using standard conversion rates. The value to designers is obvious.

Effects of product complexity on human learning in assembly and disassembly operations

“…With the shift towards low-volume production and the need for sustainable manufacturing, it is crucial to assess the learning effect across different product types, which are typically characterised by different levels of complexity. It is also vital that product assemblies take into account subsequent disassembly and material reuse, contributing to waste minimisation (Desai and Mital, 2017;Qiu et al, 2022;Tolio et al, 2017).…”
