在傳統的『隔牆式』產品設計程序中，因為各部門間缺乏有效的資訊傳遞與溝通，往往會造成本與時間等資源的耗費，Concurrent engineering 概念的產生， 即是為了化解產品設計人員與後續各功能工程人員之間的隔閡，以提升產品開發的效率與效能。

In the traditional “Over-the-wall” product design process, cost and time are usually wasted due to ineffective communication and information sharing. The concept of “Concurrent Engineering” is then created to break down the barriers between product designers and staff in Quality Control and Product Manufacturing to increase the efficiency and effectiveness of product development.

本研究嘗試利用『TRIZ』來解決『DFX』中『DFMA guidelines』之間的衝突。 首先由文獻的探討與分析中，找出最具有代表性的13項DFMA guidelines； 然後再確認應用各guidelines之後，可能會產生的『improves parameter』 和『worsening parameter』，若同時存在improves parameter 與 worsening parameter，即形成了衝突；最後利用TRIZ的『Contradiction matrix』 尋找合適的『inventive principles』 以解決此衝突， 如此即可取代『Trade-off』的解決方式。 透過以上的解題流程， 在分析完所有13項DFMA  guidelines之後， 由統計結果可知， 出現次數最多TRIZ的『inventive principles』為copying、inversion。

此外，本研究亦將上述的解題流程成功應用於三個真實案例分析中。

This study attempts to use “TRIZ” to resolve the conflict of DFMA guidelines in DFX. Firstly, from the analysis and discussion of the publications, we will select the 13 most representative DFMA guidelines; then verify the improving parameter and the worsening parameter that may have been generated, after applying the various guidelines. If the improving parameter coexists with the worsening parameter, this becomes a conflict. Lastly, we will use TRIZ’s contradiction matrix to locate an inventive principle capable of resolving this conflict. It will then replace the solving method of “trade off”. When completing analyzing all 13 DFMA guidelines, we will know from the above solving flow and the statistical results that the most frequently occurred TRIZ’s inventive principles are copying and inversion.

In addition, this study has successfully applied the above solving flow on the analyses of three real life cases.
