摘要

Design for Environment (DfE) has been defined as the systematic integration of environmental considerations into product and process design. And it has been discovered that material and space can be saved when several functions are integrated into a single product by taking advantage of common components. In this design and development project, a multipurpose thresher was designed based on an integrated concept of design for modularity, disassembly, demanufacturing and remanufacturing. The machine can be used to thresh various types of farm produce such as rice, sorghum, cowpea and rye by changing the concave and the cylinder (threshing drum). The configuration of the machine enables access to most of the component parts without changing the tools needed for disassembly because the same type of fasteners was used. Furthermore, the functional units (the shelling unit, the separation unit and the grading unit) were assembled into modules such that only the faulty part needs to be replaced if necessary. The design was so simplified that the operator can make the changes for different uses without any difficulty. The machine has been successfully tested with a number of these products and it is scheduled for tests with other produce like corn and peanuts. The modularity of the functional unit will facilitate multi-lifecycle use of machine and/or its component parts. The uniformity of the liaisons and simplification of the configuration will reduce both the disassembly times and maintenance cost. By this integration, the material requirements for four different machines are conserved, environmental emissions that would be associated with the manufacture, transportation and disposal of four machines are eliminated while the capital requirements by farmers for machinery are reduced to about a quarter. Consequently the total lifecycle cost is kept minimum while the eco-efficiency is maximized.
