本研究先以投射燈的功能字為主,提出修正式 DEMATEL方法,其主要為收集LED投射燈之相關技術領域中針對一功能領域與另一功能領域間重複定義或定義相同的專利技術字所佔之常態化數值比例值,依所計算的常態化數值比例值,來評估各功能領域間的相互影響程度0~4之值,以取代傳統的專家問卷方式。接著再依照修正式DEMATEL運算步驟求出總關係影響矩陣、直接/間接關係圖及(D+R)值與(D-R)值之因果圖。此(D+R)值與(D-R)值之因果圖可協助判斷LED投射燈之各功能領域間的相互受影響程度。本研究亦進行LED投射燈專利功能生命跨距及LED投射燈專利之功能生命週期分析,本文對LED投射燈合併進行各功能領域之DEMATEL因果圖及各技術領域之DEATEL因果圖、功能活動力趨勢表、專利功能生命跨距與專利功能生命週期之分析。本文收集LED舞台燈上相關專利,利用斷詞斷字系統計算各相關專利之關鍵技術字、零組件元件字及功能字之常態化數值,分析歸納各第一層技術類別之技術字及零組件元件字字群,定義其第一層技術類別之第二層技術類別及功能類別,進而建立LED舞台燈之技術功能矩陣。接著以LED舞台燈為載具,本文亦計算LED舞台燈之相關功能領域中針對一功能領域與另一功能領域間重複定義或定義相同的專利技術字所占之常態化數值比例,應用修正式DEMATEL方法得到評估各技術領域間的相互影相程度0~4之值。進而計算得到總關係影響矩陣、直接/間接關係圖及(D+R)值與(D-R)值之因果圖,判斷LED舞台燈之各技術領域間的相互受影響程度。本文亦計算LED舞台燈之相關技術領域中針對一技術領域與另一技術領域間,重複定義或定義相同的專利技術字所佔之常態化數值比例,應用修正式DEMATEL方法得到評估各技術領域間的相互影相程度0~4之值。進而計算之技術領域修正式DEMATEL方法的因果圖。此外亦進行LED舞台燈之專利技術生命跨距及專利技術生命週期分析。本文針對LED舞台進行合併各功能領域之DEMATEL因果圖,各技術領域之DEATEL因果圖、功能活動力趨勢表、專利功能生命跨距與專利功能生命週期之分析。本研究亦進行LED舞台燈應用結合改良式餘弦相似度及機率方法進行LED舞台燈之新投入專利之專利歸屬判別,先以改良式餘弦相似度做篩選再以機率方法計算出專利可能歸屬之技術或功能類別。最後提出藉由合併分析DEMATEL因果圖、功能活動力趨勢表、專利功能生命跨距與功能生命週期之分析方法,探討LED舞台燈功能領域相關專利發展空間。本研究亦進行LED舞台燈之IPC分析、發明人分析、各公司核心競爭力及功能活動力趨勢分析,上述分析之結果可提供給企業及工程師,作為新專利產生之參考。此外亦可使企業了解競爭者之核心競爭力。
The paper, mainly focusing on functional words of projection light, firstly proposes to use modified Decision-making Trial and Evaluation Laboratory (DEMATEL) method, mainly intending to find the ratio of normalized numerical values of patents’ technical words with repeated definitions or the same definition in a functional area and another functional area in the related technical area of the collected LED projection lights. Based on the calculated ratio of normalized numerical value, the paper evaluates the mutual influence at values 0~4 among different functional areas in order to replace the conventional questionnaires for expert opinions. After that, according to modified DEMATEL algorithmic steps, general relational influence matrix, direct/indirect relationship diagram and the causal diagram between (D+R) value and (D-R) value can be found. The causal diagram between (D+R) value and (D-R) value can help judge the mutual influence among different functional areas of LED projection light. The paper also analyzes the functional life span of LED projection light patents and the functional life cycle of LED projection light patents. The paper conducts merged analysis of DEMATEL causal diagram of different functional areas, DEMATEL causal diagram of different technical areas, activity trend chart of functions, functional life span of patents, and functional life cycle of patents. After collecting the related patents of LED stage light, the paper uses term and word segmentation system to calculate the normalized numerical values of key technical words, part/component words and functional words of the related patents, analyzes and summarizes the groups of technical words and part/component words in the first-layer technique category, defines the second-layer technique category and function category of the first-layer technique category, and further establishes a technical/functional matrix of LED stage light.
After that, taking LED stage light as a carrier, the paper also calculates the ratio of normalized numerical values of patents’ technical words with repeated definitions or the same definition in a functional area and another functional area in the related functional area of LED stage light. Applying modified DEMATEL method, the paper evaluates the mutual influence at values 0~4 among different technical areas. Furthermore, the paper makes calculation and achieves general relational influence matrix, direct/indirect relationship diagram and the causal diagram between (D+R) value and (D-R) value, and then judges the mutual influence among different technical areas of LED stage light. The paper also calculates the ratio of normalized numerical values of patents’ technical words with repeated definitions or the same definition in a technical area and another technical area in the related technical area of LED stage light. Applying modified DEMATEL method, the paper obtains values 0~4 for evaluation of mutual influence among different technical areas. Furthermore, the paper makes calculation and achieves the causal diagram of modified DEMATEL method of technical areas. Besides, the paper also analyzes the technical life span and technical life cycle of LED stage light patents. Focusing on LED stage light, the paper conducts merged analysis of DEMATEL causal diagram of different functional areas, DEMATEL causal diagram of different technical areas, activity trend chart of functions, functional life span of patents and functional life cycle of patents. The paper also combines improved cosine similarity with probability method to differentiate the patent category of the newly added patent of LED stage light. After using improved cosine similarity for screening, the paper uses probability method to calculate which technical or functional category the patent may belong to. Finally, the paper proposes that through merged analysis of DEMATEL causal diagrams, activity trend chart of functions, functional life span of patents and functional life cycle of patents, the development room for the functional area-related patents of LED stage light can be explored. The paper also conducts LED stage light’s IPC analysis, inventor analysis, different companies’ core competitiveness analysis, and analysis on activity trend chart of functions. Results of the above analyses can be a reference for enterprises and engineers in producing new patents. In addition, enterprises are also able to know the core competitiveness of their competitors.
