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.
