고객가치 제공을 위한 TRIZ 발명원리 분석: TV 제품 특허를 중심으로

This study aims to propose the invention principles of helping to devise patents that can provide customers with better values when companies develop the patents on TV products. 346 patents on TV products were used for the analysis of TRIZ invention principles and the customer value. 8 items for the customer value were categorized through the determinants of TV replacement presented by NPD DisplaySearch and TV patents were analyzed by the items. As a result of the patent analysis, 23 principles among the total 40 TRIZ invention principles were found to be embedded on TV patents, of which 10 principles accounted for 80% of the total. The invention principle ‘Feedback’ occupied the highest frequency of use, and the lowest was ‘Curvature increase/Spheroidality’. The frequency analysis result of customer values included on TV patents showed that the highest ‘Ease of use’ and the lowest ‘Stereoscopic image’. In addition, we found that there is no significant difference between TV patents and NPD DisplaySearch’s ranking in customer value. From the result, it can be concluded that it is effective to use 'Feedback' and 'Preliminary action' principles for devising patents providing highly preferred customer value.
