碩士 === 龍華科技大學 === 資訊管理系碩士班 === 107 === Netcom product is one of the important chains in Taiwans electronics industry.In the era of rapid technology upgrading, many new companies have emerged opportunities, but some companies have been eliminated because they did not follow up the latest follow up the latest technique progress. Owning the latest technology cant guarantee to have customers; retaining customers is the key to the Netcom industry. Developing new product technology by customers need is the main course for Netcoms industry. This thesis is aimed at the heat dissipation problem of the cable modem in the customized design of the product. Based on the Deming Cycle (PDCA), the TRIZ method is used in product planning, quality characteristics, and design checking. Then we carry out the product development process (Do). We used the TRIZ 39 engineering parameters and the TRIZ 40 innovation principles, via the contradiction matrix, to design the heat dissipation structure and dissipation direction of the cable modem. And we use the experimental analysis, continuous improvement (Check), and finally mass production (Act). This thesis took simulation analysis and practical product verification. In the product design of the cable modem, the TRIZ contradiction matrix is used to solve the heat dissipation problem. Increasing the number of vents in the plastics housing case, the heat sink fin’s direction and its quantity and its material characteristics for main-chip IC, and the ultra-soft thermal pad, all of them can help to improve the overheating of the main chips during heavy loading. This research results can provide a reference for Netcom companies to design the cable modem in order to shorten the development time and reduce the R&D costs.
