Space claim analysis for addressing maintenance of key components in complex products

Abstract

Purpose The purpose of this paper is to provide a new approach involving guidelines and supporting techniques that guarantees all needed space for appropriate product maintenance. Design/methodology/approach The approach is based on two major areas: field survey to understand how maintainability parameter is applied and converge theory and practice into a systematic space claim method using computer-aided design (CAD) systems to assure proper maintenance procedures at design stages. Findings Case studies from a truck industry conducted following the proposed approach contrast the savings that can be achieved by using a proper space claim for aftermarket needs against an unsuitable level of participation by maintenance personnel during the design development. Research limitations/implications This approach is highly dependent on maintenance experts with suitable skills on CAD systems. Practical implications Products developed according to the approach envisaged can result in following aspects: lower repair time, better maintenance procedures on key components, easier preventive maintenance, less need for special tools, more ergonomic design, better communication between design and service engineers, simplicity and less complex training. Social implications Further research on maintainability will provide new information on how to apply this parameter on product development process (PDP), so design teams can better understand and address this relevant issue. The proposed method has been introduced in the PDP of a major multinational automotive company. Originality/value A new process is presented, considering the protection of needed spaces for maintenance procedures throughout the PDP, diverging to other studies that only propose analysis addressing maintainability at singular point in time during the product development. In just one case study presented, savings of US$1.3m were achieved by applying this space claim approach.

A hierarchical and process-oriented framework for disassemblability evaluation in product maintainability design

“…As a result, in most cases, designers can achieve the disassemblability of single components separately, but the disassemblability of the whole product cannot be understood [4]. For example, Moscheto et al [35] studied the disassemblability of key components in complex product, and did not evaluate the whole product. Moreover, most existing evaluations only focus on the current operation.…”

Selective disassembly sequence optimization based on the improved immune algorithm

“…Thus, it has wide applications in maintaining, remanufacturing and recycling. Junior et al (2017) studied the maintainability for product design. They argued that the access space for components to be maintained must be big enough for disassembly inspection.…”
