Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate fingerprint identification module and touch control recognition module are used, then each module can perform its dedicated function, but resource utilization decreases
Solution Approach 1:
The patent implements multi-functionality by enabling the first recognition device to perform both fingerprint identification and touch control recognition. The first driving chip receives data from the first recognition device and can process it for either fingerprint authentication or touch control functions, allowing one hardware component to serve multiple purposes and thereby improving resource utilization while maintaining dedicated function performance
2Productivity
If integrated recognition device performs both fingerprint and touch control, then resource utilization increases, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the recognition system into distinct functional areas (first recognition area for fingerprint, second recognition area for touch control) and using separate driving chips (first driving chip for fingerprint processing, second driving chip for touch control processing). This modular segmentation allows the system to maintain clear functional boundaries and simplify control logic while still achieving high resource utilization through the ability of the first recognition device to serve dual purposes
