Modularization of delta 8Ah emergency lamp product based on Design for Remanufacturing (DFR) and Design for Environment (DFE) criteria

Abstract

A modular product is made up from various different modules that can be easily attached / detached. These modules can be manufactured, assembled and repaired separately. Modular product concept enables end-of-life product to be reused, recycled or even remanufactured as each component of the product has been defined according to its functions into different modules. The product components are split into a number of modules based on certain criteria. In this research, there are two criteria used, which are Design for Remanufacturing (DFR) and Design for Environment (DFE). The Hierarchical Clustering Algorithm (HCA) method also applied to devide product components into a number of modules. The Delta 8Ah emergency lamp product, which is used as research object in this paper, consists of 18 different components. Preliminary research shows that there are 5 modules which can be used as recommendation for product design. However, further research concludes that the final recommendation for product design suggests only 4 modules. As proposed improvements, there will be reductions in the total number of screw FSC 11, screw FSC 13 and cord holder components; changes in the material used for battery holder component; addition of features on housing component and a new component called elastic cover; simplification of reflector and housing components; and a reduction in the additional tools required for disassembly and assembly processes. These recommendations are based on considerations for improving the remanufacturing process as well as creating environmental-friendly product.
