Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the processor handles all touch operations and mode switching directly, then the system can operate with simpler architecture, but the processor burden increases and efficiency decreases
Solution Approach 1:
A touch processing unit is introduced as an intermediary component between the touch detection unit and the processor. This dedicated unit handles touch operation determination and mode switching tasks, thereby reducing the processor's workload and improving overall system efficiency without significantly increasing architectural complexity
2Power
If mode switching is handled by the processor, then the system can maintain simpler control logic, but the processor load increases during mode transitions
Solution Approach 1:
The mode switching function is extracted from the processor and implemented as a dedicated touch processing unit. This separation allows the processor to maintain its full processing power for computational tasks while the touch processing unit handles mode transition operations independently, improving overall system performance
