整合組裝與設變知識之引導式機構設計

隨著科技的快速發展，資訊及消費性電子產品推陳出新，各家廠商為了保持其競爭力，無不致力於縮短產品設計的生命週期，其中若能將產品的機構設計流程標準化，且於設計階段即將模具設計的相關規範納入考量，必能提升產品生產效率，並可減少設計錯誤率。因此本研究利用CAD軟體與網路技術的整合，開發一套機構設計引導流程，讓使用者依標準化流程的步驟進行設計。此引導流程導入由上而下的設計概念，於模型匯入後並建立專案檔，以各零組件之座標做為組裝依據，達到自動化組裝的一致性，並於最大組件檔下建立單一骨架檔，將各零組件之參照特徵建構於骨架檔中，後續建立之機構特徵則以此骨架為主，便可降低於各個零組件檔中分別建立參照的繁複性，以及避免機構間的干涉和錯位等問題。另外，藉由歷史案例之整理，將種類繁多的機構型式進行分類後，依照規格尺寸設計，加上以往個人經驗建構的特徵，整理歸納成標準化參數的建構，以規格尺寸的選單控制機構特徵內所包裝之參數，便可自動化設計變更機構特徵，不僅能縮短未來工程繪圖的時程，讓設計者能快速建立機構特徵及進行設計變更，並且減少不必要的錯誤產生，達到為組裝與為設變而設計的目的。而透過本研究之標準化引導流程，能夠節省58%以上之設計時間，提升產品生產效率。

With the rapid development of technology, information and consuming electronic products weed out the old and bring forth the new, in order to remain competitive, every manufacturer dedicated to shorten the product design life cycle, if the product design process can be standardized, and consider rules with mold design in the design stage, it will be able to improve the production efficiency and reduce design error rate. Therefore, this study use CAD software Pro/ENGINEER and network technology integration to develop a mechanism design process, it make users follow the standardized steps to design. This guided process use the concept of top-down design, after model imported will create a project file, it let every part and component to assembly according to their coordinate that achieve the consistency of automated assembly. It also create a single skeleton file at the largest component, making every part’s and component’s reference feature to build in, and the after created features will depend on this skeleton file. That can reduce the complexity of creating references in each parts and components, also avoid each feature’s interference or dislocation and other problems. In addition, by historical cases of consolidation, the wide variety of mechanism types will be classified and follow standardized size to design. Add features by personal experience to construct, it be arranged to standardized construction of features. Use standardized size menu to control the packaged parameters in mechanism features can automatic change design, not only shorten the time course of engineering drawings of the future, so that designers can quickly build mechanism features and change design, but also reduce unnecessary errors generated, to reach the purpose of design for assembly and change. Through this study’s standard guided process, it can save more than 58% of design time and improve production efficiency.
