In the age of knowledge explosion, a Keener competition exits between corporations and puts great pressure on leaders. Enterprises should, therefore, rely on R&D and Marketing strategies for higher competency.In construction industry, most inventions result form brainstorming, abundant inspiration, or empirical cases, so that a systematic method, TRIZ, is introduced and applied to obtain better design or alternatives at the beginning of projects. However, tough issues of TRIZ arise from subjective judgments and blank cells of the traditional contradiction matrix of size 39x39. Therefore, this study proposes a systematic innovation model that AHP, GRA, updated contradiction matrix of size 48x48, analogical thinking, and a check process to deal with tough problems systematically. In addition, concepts of PDCA and VE are applied in this model to enhance the completeness of the process.Finally, through two examples, pre-stressed concrete and hoop reinforcements of columns, it can be concluded that this model is capable of using TRIZ inventive principles more efficiently, effectively, and systematically to increase project values.
