Abstract Details

2002, MS, University of Cincinnati, Engineering : Industrial Engineering.
Designing a product to enhance disassembly results in significant savings in time, cost and effort associated with disassembly. Study of relevant literature indicates the presence of numerous disassembly evaluation criteria and methodologies that are quantitative in nature. Similarly, as far as design for disassembly is concerned, there is an abundance of literature on tips to improve recycling end-of-life components. In addition, a number of rules have been provided that would enhance the disassemblability of a product such as say minimal use of fasteners (Use snap fit) or reduction in material variety. These rules have not been mentioned in conjunction with one another. A systematic methodology to incorporate disassembly considerations in the product design process is conspicuous by its absence. Incorporation of disassembly as one of the ‘X’s in the DfX paradigm (in addition to functionality, cost, manufacturability, assembly, maintenance, quality and serviceability) might, in a multitude of cases entail a complete changeover in product design. Disassemblability of a product is a function of several parameters such as exertion of disassembly force to affect disassembly, degree of precision required for effective tool placement, weight, size, material and shape of components being disassembled, use of tools etc. The methodology described in this thesis assigns time based numeric indices to each design factor. Time based indices make for easy and quick determination of disassembly time. In addition, the value of this numeric index is inversely proportional to the relative ease with which each of the design factors can be addressed during disassembly. A higher score indicates anomalies in product design from the disassembly perspective. Addressing these anomalies in isolation and/or in combination can result in significant design modifications rendering an overall increase in disassemblability of the product. However, decisions regarding design modifications have to be essentially based on weighing several factors such as technical and economic feasibility as well as after a thorough consideration of the effects such changes may have on the overall functionality and structural rigidity of the product as a whole.
