#### 4.3.1 Generating Innovative Solutions with TRIZ  
After the innovation dimensions have been identified, the technological innovation elements in the innovation dimensions can be iteratively coupled with the inventive principles in turn, under the guidance of domain experts. The inventive principles that can identify technological opportunities through coupling can be retained to generate product innovation solutions.  
This paper identifies the following four product innovation opportunities. The specific technology opportunities are described in Table 7.
