Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple signal collecting devices are deployed for redundancy control, then signal control reliability is improved, but device complexity increases
Solution Approach 1:
The patent implements redundancy control by deploying duplicate signal collecting devices (first and second signal collecting devices) at the same mounting positions. Each device collects dynamic information independently, creating redundant copies of the signaling system. When a fault is detected in one device, the controller can switch to using data from the other device, ensuring continuous reliable operation without requiring system redesign.
2Reliability
If redundant signal collecting devices are implemented, then fault detection capability is improved, but system cost increases
Solution Approach 1:
The patent uses duplicate signal collecting devices positioned at the same locations to create redundant signaling paths. This copying approach enables fault detection by comparing outputs from identical devices, allowing the system to identify and isolate failures while maintaining cost-effective operation through standardized component replication.
3Measurement precision
If real-time fault detection and data replacement is implemented, then signal positioning accuracy is improved, but processing complexity increases
Solution Approach 1:
The controller continuously monitors dynamic information from both first and second signal collecting devices, comparing their outputs in real-time. When a fault is detected in one device, the controller automatically switches to using data from the functioning device, maintaining accurate positioning signals. This feedback mechanism ensures high measurement precision while managing processing complexity through automated fault response protocols.
