本研究主要探討電源供應器產業之突破式創新的可能性。透過文獻了解創新的涵意和學者對創新的分類，深入比較「維持性創新」（Sustaining Innovation）與其高階入侵（High-end encroachment），以及「突破式創新」（Disruptive Innovation）之三種低階入侵（Low-end encroachment）方式，分別為：即刻市場入侵（Immediate low-end encroachment）、邊緣市場入侵（Fringe-market low-end encroachment）、分離市場入侵（ Detached-market low-end encroachment）。 首先探究電源供應器之技術、產業現況、供應鏈結構及電源供應器的應用分類；將無線充電器歸類為新科技，針對無線充電技術的市場、聯盟、應用、未來機會做深入的剖析。為驗證無線充電技術之突破式創新的可能性分析，本研究採取學者Schmidt（2008）所提之「辨別創新的三步驟」進行突破性創新的驗證，以「無線方便性」與「充電速度」為關鍵指標。現有充電器的消費者比較重視「充電速度」，而新市場的消費者比較在意「無線方便性」，兩者的需求曲線不同，無線充電科技因提供與既有市場不同的新功能，所以被歸類為「低端突破式創新」之「分離市場」入侵。分離市場的消費者願意為無線的方便性付出較高的價格購買新產品。在新產品推出初期不會侵蝕主流市場的銷售，但經過一段時間，當價格下降及充電速度性能提升後，新產品會「低端突破」原有市場；到最後，新產品會往主流市場及高階市場擴散而影響既有產業和原來的市場結構。 本文藉由與產業專家的深入訪談得知目前既有企業對於新科技尚未開始準備，著實也驗證了Christensen（2005）提過主流企業常常因為過度著重現有技術，而忽略突破性科技的存在。最後，本文建議既有電源供應器產業應多留意突破性科技的入侵且適時跨入新科技，才能在突破性科技崛起時做好準備。 / The main purpose of this research is to examine the potential of disruptive innovation on the power supply industry. This article investigates the definitions and the classifications of innovation by various scholars. It identifies sustaining innovation with its high-end encroachment and disruptive innovation with its three approaches of low-end encroachment which are immediate, fringe-market, and detached-market. This article reviews the power supply industry and its technology, applications, market status, supply chains and then investigates the wireless charging industry and its technologies, evolutions, standards, and market opportunities. To identify the potential of wireless charging becoming disruptive technology, the article refers to the three-step framework of Schmidt (2008) to assess the potential diffusion pattern. The primary attribute of the incumbent is the charging time whereas the primary attribute of new technology is its wireless convenience. The results classify wireless charging as a low-end detached-market encroachment. The current and new products initially sell to the two opposite ends of the market and the highest willingness to pay for each market in the beginning are different, which are “detached “from one another. Over time, charging time would be expected to improve and cost would be expected to decrease, wireless chargers will be more favorable to high-end users of the wired chargers, and eventually current market will be encroached by the new technology. The interviews with incumbents present that current power supply firms have not initiated the development of wireless technology. Companies usually pursue sustaining innovations at the higher tiers of their markets because this is what has historically helped them succeed and they often missed the chances to disruptive innovation. (Christensen, 2005) The results suggest the established organizations to take more efforts to start looking into the disruptive technology so that established organizations will not be displaced by the new firms.
