本研究先以LED集魚燈為例，探討其相關文獻及各項專利分析，利用多屬性決策分析(MADM)進行決策過程之評估，透過產品技術準則代入修正式FUZZY ANP計算相關權值與修正式FUZZY DEMATEL算出總影響關係矩陣，發展出結合修正式FUZZY DANP法之修正式FUZZY WASPAS法，評選出優先改善方案。
此外，再以手術燈為例，先透過手術燈之相關文獻及各項專利分析，得出第一層技術領域分為1.整體支架結構、2.燈罩結構、3.燈具控制技術，再由第一層技術領域中，將第二層技術領域分為1.支撐支架結構技術2.燈具手把附近結構技術3.光源布置及變化技術4.燈源散熱及氣體流動技術5.燈源照射範圍及照射技術6.燈源及電源控制技術六項技術領域為六個技術準則，並由第一層技術領域建立出具有技術相依性的三個技術改善方案，分別為方案A.整體支架結構技術+燈具控制技術、方案B.燈罩結構技術+燈具控制技術、方案C.整體支架結構技術+燈罩結構技術，再透過結合修正式FUZZY DANP之修正式FUZZY WASPAS計算後得出之三個技術改善方案的優先改善順序。
最後再應用手術燈的技術/功能矩陣，對優先改善的技術方案選擇出適當的技術準則做改良，並搭配TRIZ創研法則尋找出對應的創新法則，來思考如何改良在手術燈上最優先改善的技術方案，最後提出新的改善設計案例。

Taking LED fishing light attractor for example, the paper reviews the related literature and different patent analyses, and then uses multiple attribute decision-making (MADM) to evaluate decision-making process. Through substituting product technology criteria in the modified FUZZY ANP, the paper calculates the related weights; and through substituting the above criteria in the modified FUZZY DEMATEL, the paper calculates the total influence matrix. After that, the paper develops a modified FUZZY WASPAS method that combines with the modified FUZZY DANP method, and then selects the priority of the technical improvement plans.
Besides, the paper subsequently performs decision-making selection of the technical improvement plans of surgical light. First of all, through the related literature and different patent analyses about surgical light, the paper obtains the first layer of technical field, which is divided into： 1. Lamp control technology; 2. Overall support structure; and 3. Lampshade structure. From the first layer of technical domain, the paper divides the second layer of technical field into： 1. Support frame structure technology; 2. Technology of the structure near lamp handle; 3. Light source layout and light change technology; 4. Lamp-source heat dissipation and air flow technology; 5. Lamp-source illumination range and illumination technology; and 6. Light source and power source control technology. The paper takes these six technical fields as six technical criteria. From the first layer of technical field, the paper establishes three technically interdependent technical improvement plans, namely： Plan A. Overall support structure technology + Lamp control technology; Plan B. Lampshade structure technology + Lamp control technology; and Plan C. Overall support structure technology + Lampshade structure technology. After calculation by the method combining the modified FUZZY DANP with the modified FUZZY WASPAS, the paper acquires the priority order of improvement for the three technical improvement plans.
Finally, applying the technical/functional matrix of surgical light, the paper selects from the most prioritized technical improvement plan some suitable technical criteria to make improvement. The paper also uses TRIZ innovative research method to find the corresponding innovation rules, and then think about how to improve the most prioritized technical improvement plan of surgical light. As a result, a new improvement design case is proposed.
