| Summary: | 碩士 === 國立虎尾科技大學 === 機械與機電工程研究所 === 95 === In order to meet driver’s lighting safety and satisfy customer’s requisition, we will probe into the headlamp development, the optic principle of headlamp design and searching for design patent of headlamp. Our research will be covered with freeform surface pattern. The apply methods include linkage, contradiction matrix, which are provided in TRIZ Theory by Altshuller. As a result, we can get a concrete scheme and a series of principles to solve problems. In order to avoid the infringement of the patents, we use TRIZ to dodge the present patents. Otherwise, six-sigma method was used to design and improve the products, services and procedures. These help us to reach quality of Six Sigma, promote quality performance and meet customer’s requisition. Finally, we use innovative scheme to simulate and analyze lighting pattern. An aluminum prototype is created to verify our design and also apply it to current market.
TRIZ helps R&D quite a few. It also can get rid of tradition thinking and can speed up design. Nowadays, every enterprise can apply this method to create and improve their products and also can increase benefits. There are two concrete contributions in this paper. (1) Apply for the domestic patent: The reflector improvement of headlamp – application No. 096203329. (2)Utilize combination rotating parabolas to replace freeform surface, and the rotation angle of these parabolas can’t exceed 0.5 degree.
