碩士 === 明新科技大學 === 管理研究所碩士在職專班 === 105 === This study focused on Riken GD-K77 single-point type gas detector encountered in the actual use of the improvement of the situation. Nowadays, the rapid changes in technology, the use of gas as the increasing of science and technology is also followed the process of raw materials. In addition to the progress of science and technology, the society more and more attention to the safety of the lives and property of persons; The Ministry of the Republic of China and the Environmental Protection Department has a staff workplace occupational health and safety management plan and the strain equipment and detection and fire alarm devices for toxic chemicals management Approach and other related EHS regulations, so the sale of the gas detector manufacturers to follow the trend, such as the emergence of a large number of bamboo shoots. And the gas detector manufacturers because technology is gradually mature and to increase the market competitive power, Will the entire cost of purchasing and follow-up materials, Fitting the price down, but relatively due to lower prices, leading to relatively simple selection of materials from the use of supplies and spare parts, resulting in a decrease of service life. Although reducing the purchase cost but the cost of increasing the running cost. Therefore, to solve the lack of the design of gas detector components has its necessity. In this study, function analysis and cause-effect chain analysis were used to find out the cause of the detector failure. The pump failure is the main cause of the detector failure, and the aging of the rubber rings is the dominating reason of the pump failure. Heat and oxygen are the factors that cause aging. Due to the reason mentioned above, we designed a protection box to separate heat and oxygen away from the rubber rings by using contradiction matrix and inventive principles. This design can increase the life of rubber rings and can thus decrease the chance of the detector failure.
