隨著網路技術的蓬勃發展，網際網路已成為大家矚目的焦點，再加上電子商務的推波助瀾，網際網路已在不知不覺間，從新潮的名詞變成日常生活中的一部份。舉凡資訊查詢、聊天交友、購物、繳稅等行為愈來愈普遍，對人們的影響繼續不斷地增加中。
網際網路技術對人們行為所帶來的變化，不但創造了許多新的商業機會，也迫使一些傳統的行業也必須對此作出適當的改變來回應，顯然的，也會影響到設計及製造領域。本研究即是探討網際網路技術與設計製造結合的可能方式。
『概念設計』是一般產品設計步驟的早期階段，也是本研究認為最容易與網際網路相結合的部分。藉由網際網路上的優渥資源，以及許多成熟的相關技術，可以提供協助，讓一般設計者，以最小的成本換取最大的服務。
本研究之研究重點在於系統架構及虛擬原型之設計，網路技術使用分散式物件技術，虛擬原型(Virtual Prototyping)使用VRML實作，並實作介面用以整合資源。本文將以機械組裝設計為例來驗證系統之架構。

Due to the development of the network technology, Internet plays the most important role. With the growing of e-commerce, WWW has been the part of our regular life. Some behaviors in the Internet are much more popular, like data search, talking, shopping and pay tollage. The effect to people is increasing on using Internet.
The change of the behavior of people using Internet not only made a lot of commercial chance but also force some traditional industry made some change to response it. Obviously, it also affects the domain of the product design and fabrication. The goal of this thesis is to discuss the possibility of combining product design and WWW.
Generally, “concept design” is in the early level of product design. We believe that it is also the most suitable part of product design levels to combine with WWW. It can support designers the most help by the way of using the rich resources and technology on Internet.
This research focuses on the design of the system architecture, distributed object technology, and the virtual prototype model implemented by Java and VRML. A case study of mechanical assembly design will be constructed to demonstrate the feasibility of a client-centered architecture.
