| Summary: | 碩士 === 實踐大學 === 企業管理學系碩士在職專班 === 105 === Wireless charging technology has been one of the most popular technologies as more mobile devices are released and the demand on battery life increases. However it doesn’t yet have a global standard. According to the research firm IHS, global wireless charging receiver and transmitter market is expected to grow from 25 million units in 2013 to 1.7 billion units in 2023.
Despite long development of portable electrical devices, the current biggest technical bottleneck is the improvements in battery efficiency can not catch up with that of the product features. Lighter and more compact design has always been and continues to be the main design goal and development trend. Although most of the relevant components are constantly improving their performance and reducing their sizes, which closely follows the Moore’s Law, battery, however, is the only exception that hasn’t seen any significant breakthroughs.
Wireless charging for mobile systems is one of Qualcomm’s main projects. Its biggest hurdle is the performance of receiver antenna still requires significant improvements. Analyzing the technologies, materials, and manufacturing processes used in current wireless charging systems for mobile phones, this preliminary study based on the idea of discontinuous innovation, concludes the receiver performance could have been greatly improved if alternative design principles are adopted.
This study incorporated several S-curve theories, defined the market demand using the Csikszentmihalyi (three-pronged systems model of creativity) , and then applied the House of Quality (HOQ), the core toolset of Quality Function Deployment (QFD), to setup the technical specifications. The research, design, and implementation of the product is thereafter conducted accordingly, with new materials applied and innovative processes imported.
