Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If continuous power is applied to transistors in circuit blocks, then the circuit blocks remain ready to operate, but transistor degradation occurs and signal properties deteriorate
Solution Approach 1:
The patent implements periodic switching of power supply to circuit blocks based on operation modes. Power is continuously supplied only to actively operating circuit blocks, while standby blocks receive intermittent power. This periodic power management prevents transistor degradation in inactive blocks while maintaining readiness of active blocks, resolving the contradiction between operational readiness and reliability.
2Reliability
If circuit blocks operate only when functions are performed, then transistor degradation is reduced, but signal generation may become abnormal due to property degradation
Solution Approach 1:
The patent employs feedback mechanisms that monitor signal properties from circuit blocks. When abnormal signals are detected due to transistor degradation, the system automatically adjusts power supply timing and duration to prevent further degradation. This closed-loop feedback control ensures signal quality while minimizing power application to inactive blocks, addressing both reliability and abnormal signal generation concerns.
3Productivity
If power is continuously applied to maintain circuit blocks in operational state, then operation performance is maintained, but transistor stresses increase and properties degrade
Solution Approach 1:
The patent dynamically adjusts power supply characteristics based on real-time operation mode detection. Circuit blocks transition between continuous power supply during active operations and intermittent power during standby states. This dynamic power management maintains optimal operation performance when needed while reducing transistor stress during idle periods, resolving the contradiction between productivity and component strength.
