  • 本研究提出一個萃智(TRIZ: Theory of Inventive Problem Solving)衝突分析與解題的流程。此分析流程整合了因果鏈分析(CECA: Cause-Effect Chain Analysis)與根源衝突分析(RCA: Root Contradiction Analysis),並能夠迅速地辨識出系統中的不利功能(functional disadvantages)及相對應的工程參數,接著連結至發明原則、分離原則/系統轉移及解題指示等衝突解決手法。本研究所提出的因果衝突鏈分析(CECCA: Cause-effect and Contradiction Chain Analysis)能夠辨識出衝突的族群(Contradiction families)且利用計量的方法來評估系統中選擇衝突解決時的優先序。
    本研究之貢獻包括: (1)提出一個同時能夠辨識出根源衝突及工程參數的衝突分析手法; (2)整合出三種問題辨識與解決的分析流程; (3)將因果鏈分析中不利功能的發生條件重新定義與分類,共分成且(AND),或(OR),結合(Combine)與直接促成(Straight Cause)四類; (4)辨識系統中的衝突族群; (5)利用計量手法來評估系統中選擇衝突解決的優先序。


    This research proposes a conflict analysis and problem solving process based on contradiction analysis and TRIZ problem solving approaches. The approaches integrate both Cause-Effect Chain and Root Contradiction Analysis to quickly identify the key functional disadvantages and the underlying contradictory parameters simultaneously. Three process flows were identified and integrated for conflict identification and problem solving. Inventive principles, separation/transition principles, and solution directives are used in the processes to solve the contradictions. The proposed Cause-effect and Contradiction Chain Analysis (CACCA) also identifies contradiction families and provides a quantitative method that can used to evaluate contradictions for prioritization.
    Contributions of this research include: 1) providing an integrated method which can identify key contradiction and contradictory parameters simultaneously; 2) Integrating a 3-passages integrated approach for problem analysis and problem solving; 3) identifying a new “Combine” relation in addition to the existing AND and OR relationship; 4) Identifying Families of contradictions; and 5) Providing a quantitative method to prioritize the importance of contradictions.
