重新設計產品空間配置之方法以簡化選擇性拆卸序列的綠色設計

Abstract

在現今商業市場中，大多數產品的生命週期因為激烈的市場競爭、科技進步與產品多樣性而越來越短，產品廢棄物也因越來越多的產品被製造出來而急遽增加。在這環境意識高漲的世代，製造產品不只是著重於數量，也著重於品質。高品質的綠色產品具有較長的生命週期以及能在其使用壽命結束後減少對環境的影響。在本篇論文中，作者提出一個針對選擇性拆卸序列而作的產品空間配置重新設計的方法架構。此架構主要包含兩個重新設計的方法：元件的重新設計以及針對拆卸的元件叢集化設計。設計為了拆卸的方針也在此篇論文中提及當成是重新設計方法的參考準則。產品設計工程師可應用此方法針對現有的產品空間配置作分析與重新設計以簡化對產品中的目標元件或模組的選擇性拆卸步驟。另外，本篇論文也考慮到元件之間的功能輸入與輸出之設計限制，像是元件之間必需如何設計的特殊關係，如此產品的原有功能才不至於改變。此外，本論文也提出一個可計算產品綠色性能的綠色評估方法，此評估方法可幫助產品設計工程師檢驗元件在壽命結束後其回收處理的選擇之配置狀況與處理難易程度。作者利用控制器為實例，實作如何利用此論文方法進行產品空間配置重新設計。

In the current business market, the life-cycle of most products is getting short, due to severe market competition, advances in technology and variety of available products. Product wastes increases dramatically because more products are manufactured. In the era of rising environmental awareness, products are made not only with quantity but also with quality. High quality green products possess longer life-cycle and reduce environmental impacts at theirs end-of-life stage. In this research, a method framework for redesigning product spatial configurations for a given selective disassembly sequence is proposed. The framework mainly contains two redesign methods: redesigning of components, and clustering design of components for disassembly. Design for disassembly guidelines are also introduced as the basic reference principals of the redesign methods. Product design engineers can analyze and redesign an existing product spatial configuration to simplify the steps needed to selectively disassemble the target components or modules using the developed methods. In addition, design constraints concerning input and output functions among components, such as specific required relationships among parts, are considered so that the original function of products will not change. Besides, a method for green assessment is provided to evaluate the green performance of products. Thus, product design engineers can examine the arrangement of components for different end-of-life options and level of difficulty in end-of-life treatments. A controller assembly is used as a case study to show how these methods performed to the product spatial configuration redesign.
