本研究發展出結合修正式FUZZY DANP與修正式FUZZY ARAS方法，用以評選出手術燈不同產品功能改善方案的優先改善方案順序。並配合產品之技術/功能矩陣去針對評選出的產品功能優先改善方案的可選用相對功能領域，再將可用之相對功能領域應用在修正式TRIZ方法做為創新想法之構想改良依據，最終得到新設計之手術燈。
上述本研究之產品將修正式FUZZY DANP與修正式FUZZY ARAS方法結合應用於手術燈。本研究先探討產品手術燈之相關專利文獻及各項專利分析，利用專利功能字篩選出產品功能之準則分為1.提高操作便利性及穩定性、2. 提高散熱性及空氣流動品質、3. 降低成本並延長使用壽命、4. 改善陰影和眼睛視覺清晰度及減少眼睛疲勞感、5. 改善光的均勻性及亮度、6. 調節照明範圍等六項功能領域，並將這六項功能領域做為評選新產品之改善方案的評估功能準則。本研究將手術燈以具有相依性的三個產品功能改善方案做為評選的方案，三個功能改善的方案，分別為方案A：提升操作便利性+提升照明效能、方案B：提高散熱性及壽命+提升照明效能、及方案C：提升操作便利性+提高散熱性及壽命。再透過以產品功能結合修正式FUZZY DANP及修正式FUZZY ARAS得到改善方案的優先權重值，評選出優先改善的產品功能方案。最後再將優先改善的功能方案相對應的技術領域運用在修正式TRIZ發明方法之創新方案改良，最終可得到新設計之手術燈結構案例。

The paper develops a method that combines the modified FUZZY DANP with the modified FUZZY ARAS for application to selection of the priority order of improvement for different product functional improvement plans of surgical light. The paper also uses technical/functional matrix of product to focus on the optional relative functional domain of the selected prioritized product functional improvement plans, and then applies the useable relative functional domain to the modified TRIZ method as an improvement basis for the conception of the innovative idea. Finally, a newly designed surgical light is obtained.
As mentioned above, the paper applies a method, which combines the modified FUZZY DANP with the modified FUZZY ARAS, to surgical light. First of all, the paper reviews the related pattern literature and various patent analyses about the product of surgical light, and uses the functional words of the patents to screen out the criteria of product functions, which are divided into six functional domains: 1. Enhancement of convenience and stability of operation; 2. Enhancement of heat dissipation and air flow quality; 3. Reduction of costs and extension of service life; 4. Improvement of shadow effect and visual clarity to the eyes, and reduction of eyestrain; 5. Improvement of the uniformity of light and brightness; and 6. Adjustment of brightness. The paper takes these six functional domains as the criteria of functional evaluation in selecting the improvement plans of a new product.
The paper takes three interdependent product functional improvement plans of surgical light as the selection plans. These three functional improvement plans are: Plan A: Enhancement of convenience of operation + Enhancement of lighting efficiency; Plan B: Improvement of heat dissipation and service life + Enhancement of lighting efficiency; and Plan C: Enhancement of convenience of operation + Improvement of heat dissipation and service life. Through the method that combines the modified FUZZY DANP with the modified FUZZY ARAS for the product functions, the prioritized weights of the improvement plans can be obtained, and the prioritized product functional improvement plans can be selected. Finally, the relative functional domain of the prioritized technical improvement plans can be applied to the improvement plan of the modified TRIZ innovative method, and then a case of the newly designed surgical light structure can be acquired.
