Automatic Rail Coupler Uncoupling with Verified Actuation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic train couplers lack simple and accessible operation while preventing incorrect actuations, especially in freight wagons, which often require manual operation and lack centralized control, leading to potential unauthorized or accidental uncoupling.
Innovation Solution
An uncoupling system for automatic train couplers that includes a control unit with verification mechanisms, allowing wireless or wired interfaces for activation and verification devices, ensuring that actuation requests are confirmed before uncoupling occurs, using manual inputs or proximity-based verification methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mechanical uncoupling device with rods or cables is used to transmit manually applied force, then the activation device is simple and accessible, but incorrect actuations cannot be prevented
Solution Approach 1:
The patent introduces a control unit as an intermediary between the activation device and the uncoupling device. This control unit receives activation requests and verification information, evaluates them, and only then controls the uncoupling device. This mediator layer prevents direct mechanical coupling that would allow incorrect actuation while maintaining ease of activation through the accessible activation device.
Solution Approach 2:
The system implements feedback by requiring verification information to be sent back to the control unit before uncoupling can occur. The control unit evaluates this feedback (verification information matching stored data) and only proceeds with uncoupling when verification is successful, thereby preventing incorrect actuations while keeping the activation device simple and accessible.
2Ease of operation
If a push-button switch is mounted externally on the car body for easy operation, then accessibility is improved, but protection against unauthorized use is reduced
Solution Approach 1:
The control unit serves as an intermediary that stands between the externally mounted push-button switch and the uncoupling device. Even though the switch is easily accessible externally, the control unit mediates the activation request by requiring additional verification information, thus preventing unauthorized activation while maintaining operational accessibility.
Solution Approach 2:
The patent replaces the direct mechanical linkage between the push-button switch and the uncoupling device with an electronic control system. The control unit processes the electrical signal from the switch and requires verification through electronic communication before activating the uncoupling device, substituting mechanical directness with electronic control to prevent unauthorized use.
3Object-affected harmful factors
If a mechanical lock via key box is implemented to protect against unauthorized use, then protection is improved, but ease of use is significantly restricted
Solution Approach 1:
The patent replaces the mechanical key box locking system with an electronic verification system. Instead of requiring physical key insertion and mechanical locking, the system uses electronic verification information transmitted to the control unit, which can be quickly validated even during slow movement, thereby maintaining protection while significantly improving ease of operation.
Solution Approach 2:
The uncoupling device itself may utilize pneumatic or hydraulic mechanisms to actually perform the uncoupling action after electronic verification is complete. This separates the verification function (electronic, quick) from the physical uncoupling function (pneumatic/hydraulic, powerful), allowing fast verification without mechanical locks while maintaining effective uncoupling capability.

AI summary
The invention relates to generic railborne vehicles and in particular rail vehicles. In particular, the invention relates to a decoupling system for an automatic draught coupling for a rail vehicle, and a draught coupling with a decoupling system of this type, and a method for decoupling an automatic draught coupling that is mechanically coupled to a counter draught coupling. The invention is characterised in that, by a user, an actuation request (X-EK) is provided for transferring the coupling closure (8) from a coupled into a decoupled position and the control unit (11) actuates the decoupling device (9) to transfer the coupling closure (8) from a coupled into a decoupled position according to the actuation request (X-EK), wherein the actuation only takes place upon or after receipt of information confirming a verification of the actuation request (X-EK).
