Engineering Contradiction Analysis
1Reliability
If conventional redundant calculation methods are used for second-layer monitoring, then system reliability is improved, but processing power and memory requirements increase significantly
Solution Approach 1:
The patent divides the calculation process into multiple segments: first-layer sensor diagnostics, intermediate calculations with monitoring, aggregate calculations, and redundant intermediate calculations. Each segment is monitored separately, allowing comprehensive verification without requiring complete redundant processing of all system operations simultaneously.
Solution Approach 2:
The system performs preliminary monitoring at the first layer by checking sensor communication and operating ranges before data reaches the second layer. Intermediate results are also monitored during calculation, preventing error propagation and reducing the burden on final redundant calculations.
2Measurement precision
If complete redundant calculations are performed for duty cycle verification, then detection accuracy is improved, but computational complexity increases
Solution Approach 1:
Instead of performing complete redundant calculations on all duty cycle parameters, the system performs partial redundant intermediate calculations on selected critical values. The monitoring focuses on intermediate results that are most indicative of system faults, providing sufficient detection accuracy without full computational redundancy.
Solution Approach 2:
The patent applies different monitoring intensities to different parts of the calculation process. Critical intermediate calculations receive redundant verification, while less critical aggregate calculations use simpler monitoring approaches. This localized quality assurance maintains detection accuracy for important parameters while reducing overall computational complexity.
