3 Design of Household Appliances Considering Remanufacturing …

for better remanufacturing (Sundin 2004). Initial important condition for successful
remanufacturing is how the product is well designed for disassembly at its end of
life. In general, the product is characterized at the initial stage of its development.
So, it is necessary to apply the design considering remanufacture at the beginning of
the product development if the product is planned to be remanufactured at its end of
life.
This paper thus presents a method to diagnose the structure of the product and
extract the major improvement factors for easy disassembly. Also, the application of
these factors to small household appliances in the product design stage is highlighted.
The validity of the design methodology is also analyzed through the demonstration
of the water purifier in terms of assemblability/disassemblability, cleaning efficiency
and processing time.
3.2 Research Method
3.2.1 Evaluation Method of Remanufacturing Convenience
In this study, we selected one representative model of remanufacturing water purifier that C Company sells on rental basis, and conducted research to improve the
convenience of remanufacturing for this product. When the remanufacturing business of household appliances is combined with a rental service, it is easy to acquire
a history-managed core for manufacturing and it can create more added values.
Table 3.1 describes the specifications of the water purifier used as a sample.
The remanufacturing convenience evaluation of the product was conducted in the
order of selection of parts to improve remanufacturing convenience, establishment of
improvement strategies for selected parts, detailed design and evaluation of improved
remanufactured products. Finally, the improved results of the remanufacturing
method are compared.
To improve the convenience of remanufacturing, the target product was selected
through remanufacturing convenience evaluation. As shown in Table 3.2, the convenience items of remanufacturing were composed of six factors affecting the convenience of each remanufacturing process. The evaluation of the number of parts is
based on Boothroyd’s concept of the minimum number of parts (Bettles 2002),
which quantifies the remanufacturing convenience results to the theoretical minimum
