Editor's Note (Toru Nakagawa, June 14, 2004)
This Case Study paper was presented, as shown above, at the 4-th Japan IM User Group Meeting in September last year. Mr. Hyo June Kim, the leader of TRIZ promotion team in Samsung, talked about the promotion of TRIZ in Samsung (as posted in a separate page) and demonstrated their results of five case studies. This paper is one of those case studies and deals with the problem of cost reduction in the DVD Pickup Optics. The Trimming technique played an important role in the problem solving. This project resulted in the reduction of cost as much as:
$3.7/each x 7 M system/year x 3 year = about $ 100 M.
In this page the original slides written in English are shown in a PDF file. While in the Japanese page, slides are shown in Japanese translation with the courtesy of Mitsubishi Research Institute. We wish to thank:
The logic of deriving the solution may not be clear enough in the slides without oral presentation, unfortunately. Mr. Serguei Khrouchtchev seems to have contributed most in the problem solving, as shown in the last slide of this presentation. Later he published a paper at ETRIA "TRIZ Future 2003" Conference concerning the analysis of historical development of DVD pickup optics from the TRIZ viewpoints. The latter paper is expected to serve to clarify the logic in this case study report; and hence it is posted separately in this Web site by the courtesy of the author.
