Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the CABC module continues to operate with a small part of logic circuits having a dysfunction, then circuit utilization is maintained, but the chance for errors increases when outputting PWM waveform
Solution Approach 1:
The patent segments the logic circuit into multiple independent units, each capable of being individually detected and repaired. By dividing the circuit functionality into separable segments, the system can identify and correct dysfunctions in specific segments while maintaining operation of other segments, thus resolving the contradiction between maintaining circuit utilization and reducing error chances.
Solution Approach 2:
The patent implements a feedback mechanism through check value input and logic operation circuits that continuously monitor the state of logic circuit units. When a dysfunction is detected, the system provides feedback to trigger automatic repair operations, allowing the system to maintain high reliability while keeping the circuit operational through real-time monitoring and correction.
2Reliability
If logic circuits in the CABC module have a dysfunction, then the module cannot continue to operate properly, but repairing or replacing the entire module reduces circuit utilization
Solution Approach 1:
The patent divides the logic circuit into multiple independent units that can be individually repaired. Instead of requiring replacement of the entire module when a dysfunction occurs, the system can isolate and repair only the affected unit, thereby maintaining overall circuit utilization while ensuring operational normality of the remaining functional units.
Solution Approach 2:
The patent enables recovery of dysfunctional logic circuit units through automatic repair mechanisms. Rather than discarding the entire module when a dysfunction is detected, the system recovers the specific faulty unit by performing repair operations, thus maintaining high circuit utilization while ensuring reliable operation.
3Reliability
If the CABC module is closed when multiple abnormal bits appear, then reliability is maintained, but circuit utilization is reduced
Solution Approach 1:
The patent performs preliminary detection and repair actions when abnormal bits are detected, rather than immediately closing the module. The system proactively identifies dysfunctional units and executes repair operations before the dysfunction can propagate and cause system-wide failures, thus maintaining both reliability and circuit utilization.
Solution Approach 2:
The patent converts the harmful effect of detected abnormal bits into a beneficial opportunity for targeted repair. Instead of treating multiple abnormal bits as a reason to close the module, the system uses the detection of these bits to trigger precise repair operations on the affected units, transforming a potential failure condition into a maintenance opportunity that preserves circuit utilization while ensuring reliability.
