Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If synchronous triggering at a fixed frequency is used, then the system structure is simple, but the trigger moment cannot be flexibly adjusted
Solution Approach 1:
The patent implements dynamic trigger control by allowing different sensors to have different trigger frequencies and phases. The trigger control device dynamically adjusts the trigger moments of multiple sensors based on configurable parameters, transforming the static fixed-frequency triggering into a dynamic flexible triggering system that can adapt to different testing requirements.
Solution Approach 2:
The patent changes the parameters of the trigger system by introducing configurable trigger frequencies and phases for each sensor. By allowing independent adjustment of frequency and phase parameters, the system achieves flexible trigger moment control while maintaining a relatively simple overall structure through parameterization rather than structural complexity.
2Measurement precision
If fixed frequency synchronous triggering is used, then the control method is simple, but the trigger moment cannot be flexibly adjusted leading to position errors
Solution Approach 1:
The system dynamically adjusts trigger moments for different sensors based on their specific requirements. Each sensor can have its own trigger frequency and phase configuration, allowing the system to achieve precise synchronization for accurate environmental perception while maintaining operational simplicity through automated control.
Solution Approach 2:
The trigger control device incorporates feedback mechanisms to detect phase alignment conditions and adjust trigger moments accordingly. By monitoring the synchronization status and automatically adjusting parameters to maintain optimal alignment, the system achieves high measurement precision without requiring complex manual operation.
3Reliability
If fixed frequency triggering is used, then the system is easy to operate, but time unsynchronization causes system failures
Solution Approach 1:
The patent implements feedback-based phase alignment detection and adjustment. The trigger control device continuously monitors the synchronization status of multiple sensors and automatically adjusts their trigger moments to maintain proper alignment, ensuring system reliability without requiring complex manual intervention or operation.
Solution Approach 2:
The trigger control system performs self-adjustment by automatically detecting phase misalignment and correcting trigger moments independently. This self-service capability ensures system reliability and prevents failures due to time unsynchronization while keeping the operation simple, as the system manages its own synchronization without external intervention.
