本文主要以LED閱讀燈為主要設計改良的載具，提供操作者在閱讀、使用筆電、電腦等辦公或學習照明的使用狀況，在夜晚或昏暗光線不足之場所的輔助照明裝置。本研究首先搜尋有關LED閱讀燈的現有的期刊、專利、論文等知識文件資料，再針對LED閱讀燈散熱性、整體結構設計與LED主體燈源之技術功能分類。然後參考相關專利及知識文件中散熱結構、整體結構與反射罩及光學罩形式之情況，定義出所需要之改善需求。再以TRIZ作為產品設計時創新方法構思的依據；經由修正式TRIZ發明法去進行LED閱讀燈散熱性、整體結構設計與LED燈源主體的創新設計與研發，本文LED閱讀燈方案將以修正式TRIZ發明法設計改良概念產生三個創新方案，每項方案內包含兩種我們所針對LED閱讀燈散熱性、整體結構設計與LED燈源主體所改良的技術。此三種創新方案以修正式ANP分析網路程序法去決定三個創新方案的優先順序。本文修正式ANP分析網路程序法，首先將目標及評估準則屬性建立階層關係，同時考量各準則屬性之間相互影響的關係，展開成網路架構。再提出依多篇技術文件及專利文獻中，考慮LED閱讀燈散熱性、整體結構設計與LED燈源主體各項功能對應之相關技術詞出現的次數及常態化比例。本研究先對各評估準則做相對重要度比較，依照技術字常態化比例來判斷相對重要尺度。若常態化比例間比較的數值差距較大，採用較大的比例分配為一單位重要尺度。若常態化比例間比較的數值差距較小，則採用較小的比例來分配重要尺度。若超過所決定的比例來做比較則單位重要尺度，增加一單位重要尺度。將所有相對重要尺度比較值，形成成對比較矩陣，並計算出權重值。再判斷一致性檢定來判斷評比值是否具有可接受性。接者ANP須考慮各評估準則間內部的相互依存關係，因此本研究採用專利技術字檢索中搜尋到的關鍵字與該項技術中所出現關鍵字出現的常態化比例，並在相關技術專利中如有發現這相同專利關鍵字，由此來判斷評估準則間的相依性。最後再對各方案間內部相互依存關係做相對重要度比對。至於各方案間內部相互依存之相對重要尺度比例判斷，為將方案內的兩種創新技術針對所要比對的評估準則間具有內部相依性的關鍵技術字的常態化比例加總，將加總後之值代入各項相對重要度比對所形成的成對比較矩陣，進一步所算出各權重值以及特徵向量。利用本文之修正式ANP分析網路程序法，將各項相對重要度比對的成對比較矩陣再代入其超級矩陣內，並計算出優先權重值，最後以各創新方案所計算出來的優先權重值，來進行產品方案的評選與決策，以決定創新方案的優先順序。
經本文之研究結果顯示，應用修正式TRIZ發明法結合修正式ANP法來決定創新研發產品的優先順序，可以有效的幫助開發人員，做決策並降低所需要之開發時程。

The paper mainly takes LED reading light as the major carrier of design improvement. LED reading light is an auxiliary lighting device for operators to use during reading, or use of notebook computer or desktop computer in the office or at home for learning at night or in any place with dim and insufficient light. First of all, the study searches the knowledge document information from the existing journals, periodicals, patent documents and research papers about LED reading light. After that, the paper performs classification of the technical functions of LED reading light, including its heat dissipation, overall structural design and high-effect optical system. Then, referring to the heat dissipation structure, overall structure, and the forms of reflector and optical cover written in the related patent and knowledge documents, the paper defines the improvement requirements needed. Furthermore, the paper uses TRIZ as a basis for development of an innovative method for product design. Using modified TRIZ invention method, the paper implements innovative design and research and development (R&D) for the heat dissipation, overall structural design and LED light-source body of LED reading light.

Regarding the LED reading light project of the paper, the design improvement concept by modified TRIZ invention method is adopted to produce 3 innovative projects. Each of the projects contain 2 kinds of the improvement techniques we focus on, including the heat dissipation, overall structural design and LED light-source body of LED reading light. These 3 innovative projects employ modified analytic network process (ANP) method to determine the priority order of the 3 innovative projects. For the modified ANP method of the paper, hierarchical relationship is firstly established between goals and evaluation criteria attributes. Meanwhile, in consideration of the mutual effects among different criteria attributes, the paper develops it to be a network structure. Besides, the paper proposes referring to several technical documents and references about patents, to consider the appearance frequency and normalization ratios of the relevant technical terms corresponding to the various functions of LED reading light, including its heat dissipation, overall structural design and LED light-source body.

The study firstly compares the relative importance among different evaluation criteria, and judges the relative importance scale according to normalization ratios of technical terms. If the numerical distance during comparison of normalization ratios is greater, a greater ratio is used to distribute a unit importance scale. If the numerical distance during comparison of normalization ratios is smaller, a smaller ratio is used to distribute importance scale. If it exceeds the determined ratio to make comparison, a unit importance scale is increased. After all the relative importance scales are compared, pairwise comparison matrices are formed, and weights are calculated. Consistency test is taken to judge whether the rating values are acceptable. After that, ANP has to consider the internal interdependence among different evaluation criteria. Therefore, the study adopts the normalization ratio of the keywords searched from retrieval of patents’ technical terms, to the appearance frequency of keywords of this technique. If the same keywords of patents are found in related technical patents, the interdependence among evaluation criteria can be judged.

Finally, comparison of relative importance is made on internal interdependence among different projects. As to judgment of relative importance scale ratio of internal interdependence among different projects, the paper finds the sum of normalization ratios of key technical terms with internal interdependence among evaluation criteria to be compared between 2 innovative techniques. The sum is substituted in the pairwise comparison matrix formed by comparison of relative importance among different items. Furthermore, the various weights and feature vectors are calculated. Using the paper’s modified ANP method, the pairwise comparison matrix resulted from comparison of relative importance among different items is substituted in its super matrix, and prioritized weights are calculated. Finally, prioritized weights are calculated by different innovative projects to undergo selection and strategic decision of product project, so as to determine the priority order of innovative projects.

As shown in the research results of the study, combination of modified TRIZ invention method with modified ANP method to determine the priority order of innovative R&D projects of products can effectively help R&D staff to make strategic decision and reduce the time required for R&D.
