Exploring the effectiveness of inventive principles of TRIZ on developing researchers' innovative capabilities

Abstract

Purpose -The purpose of this paper is to explore the efficacy of 40 inventive principles of TRIZ for developing researchers' innovative capabilities and to evaluate the extent of application of "40 inventive principles" by inventors in the Research Center of Intelligent and Signal Processing (a successful research center that is producing new products in the field of signal processing and medical engineering). Design/methodology/approach -A range of relevant literature is explored initially. A questionnaire about 40 inventive principles of TRIZ was developed based on literature review. Finally, a data analysis including descriptive statistics, correlation and regression analysis was designed by using SPSS software. Findings -The results showed that about 71 percent of the researchers have employed TRIZ above the average in their innovative products. Also these studied researchers used TRIZ principles unintentionally. Therefore, if this research center and similar institutes want to make full use of their researchers' abilities, they can facilitate innovation through offering courses on TRIZ, the principles of TRIZ and its other tools to them. Originality/value -This study is probably the first to provide an exploring of TRIZ inventive principles applications through a research center.

New Product Development Method Trends and Future Research

“…Several researchers have used TRIZ as single method such as [23,24,25,26,27].…”

“…Based on the most used tools, TRIZ is the most used tool from the 50 selected papers with 17 papers. Papers that used TRIZ such as [3,10,11,12,17,18,21,23,24,25,26,27,47,48,49,50,51]. Only seven papers from the 17 papers have a case study that implemented the TRIZ method.…”

“…We could summarize that TRIZ is relatively not user-friendly to be implemented in studies than the QFD tool. Although TRIZ can be combined with other methods such as QFD, AHP and LCA [10], DFSS [17], KE [18,23], DEMATEL [49], GRA [50], TOC [51], the use of TRIZ is still in the conceptual model, so there is a gap to use the proposed tool that combined TRIZ with this other method.…”

“…KE was used by 14 papers that used KE in their studies. Papers that used KE such as [13,14,18,23,28,29,30,31,32,33,34,35,36,37]. Only four papers from the 14 papers have a case study that implemented the KE method.…”

“…We could summarize that KE is relatively not userfriendly to be implemented in studies if compared with QFD. KE can be combined with other methods such as Data Mining [14,28], TRIZ [18,23], Fuzzy technique [31], and DSS [34], but these combined tools still in conceptual paper, and there is a gap to be implemented in a real case study. The distinctive paper in KE used paper.…”
