Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If regular inspection and maintenance work is performed on magnetic markers and sensors, then system reliability is improved, but management cost increases
Solution Approach 1:
The patent implements a feedback mechanism where detection information from vehicles is continuously transmitted to a server, which then provides feedback about the state of magnetic markers and sensors. This enables proactive maintenance based on actual system condition rather than fixed schedules, improving reliability while optimizing maintenance costs by performing work only when necessary.
Solution Approach 2:
The system enables self-service monitoring where vehicles equipped with magnetic sensors automatically detect and report the state of magnetic markers as they pass by. This distributed self-monitoring approach eliminates the need for dedicated inspection vehicles or personnel, reducing management costs while maintaining system reliability through continuous monitoring.
2Measurement precision
If detection information is collected from multiple vehicles, then measurement precision of marker state is improved, but device complexity increases
Solution Approach 1:
The patent makes vehicles serve multiple functions: they既是 transportation tools又是 mobile detection devices. The magnetic sensors on vehicles serve both their original navigation/positioning function and the additional function of detecting magnetic marker states. This multi-functionality improves measurement precision through multiple observations without adding dedicated detection equipment, thus avoiding increased device complexity.
Solution Approach 2:
The patent merges the data collection function into the existing vehicle traffic flow. Instead of creating a separate inspection system, it combines marker state detection with regular vehicle operation. The server apparatus consolidates detection information from multiple vehicles, merging redundant observations into unified state estimates, which improves precision while keeping system complexity manageable through centralized processing.
