Many design engineers in cross-domain industries have attended training classes of TRIZ to improve their innovative abilities in China.Most of them are successful,but others are not.So the latest target of the trainers is to improve the training process used now in industry in China and to make the engineers to understand the basic principles of TRIZ better.Based on the mass-engineer-oriented training model (MEOTM) and mechanical engineers’ design cases,a relationship between managing activities about the opportunities for innovation and the training process is set up.It is shown that the inventive problems come first from opportunity searching for engineers.A training and gate system for evaluation is developed to involve the managing activities of the companies in the training process.Then comparison between the general analogous process and the application of TRIZ is made,which shows the advantages and depth principles of TRIZ for the engineers to apply them confidently.Lastly a new process is formed in which opportunity searching,engineers training,inventive problems identifying and solving,and three redesign paths are connected seamlessly.The research proposes an opportunity-driven redesign path that cooperates the training and opportunity searching,which will be applied in future training classes to make more and more engineers to follow.
