Engineering Contradiction Analysis
1Reliability
If a conventional brake system is used where braking means are arranged at both ends of a brake disc, then the braking force is distributed, but it becomes difficult to reliably detect whether all braking means have been released due to potential synchronization issues and detection complexity
Solution Approach 1:
The patent extracts the detection function from a complex multi-point monitoring system and concentrates it on a single brake disc. By placing one sensor per brake disc that detects only the local braking state, the system avoids the complexity of monitoring multiple braking means simultaneously while ensuring reliable detection of the release condition.
Solution Approach 2:
The patent introduces a magnetic field as an intermediary between the braking means and the sensor. The magnetic field generated by the actuator interacts with the sensor to indicate the braking state without requiring direct mechanical connection or complex electrical wiring, simplifying the detection system while maintaining reliability.
2Measurement precision
If multiple braking means are monitored individually to ensure complete release, then detection accuracy improves, but the number of sensors and system complexity increase
Solution Approach 1:
The patent makes each brake disc self-monitoring by equipping it with its own sensor that serves multiple functions: detecting the braking state, determining release status, and providing feedback to the control unit. This universal approach eliminates the need for separate monitoring systems for each braking means while maintaining precise detection.
Solution Approach 2:
Each brake disc performs self-detection of its braking state through the integrated sensor. The system allows individual brake discs to autonomously monitor their own release condition without requiring external monitoring of all braking means, reducing the total number of sensors needed while maintaining detection precision.
3Measurement precision
If a sensor is placed near each braking means to detect release, then detection accuracy improves, but device complexity and installation difficulty increase
Solution Approach 1:
The patent merges the sensor and the brake disc into an integrated assembly where the sensor is positioned on or near the brake disc housing. This combination simplifies installation by treating the sensor-brake disc assembly as a single unit, eliminating the need for separate mounting of sensors near each braking means while maintaining accurate detection capability.

AI summary
A system (200) is described for verifying a braking release condition by braking means (201) of at least one vehicle (V), particularly at least one railway vehicle, comprising: braking control modules (202), a control means (204), a first communication means, and a second communication means distinct from the first communication means. The control means (204) is arranged to actuate at least one signaling means (210) when it is receiving, from all the braking control modules (202), respective messages of successful braking release through at least one of the first and second communication means (206, 208). An additional system (200) is also described for verifying a braking release condition by braking means (201) of at least one vehicle (V), particularly at least one railway vehicle, wherein the control means (204) is arranged to actuate at least one signaling means (210) when it determines that all braking control modules, through at least one of the first and second communication means (206, 208), are transmitting respective applied braking force messages indicating a released braking condition.
