Closing Part Drive Braking via Short-Circuit Induction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for operating closing parts on transportation devices, such as tailgates, fail to efficiently prevent unintended movements that could endanger persons, particularly when the vehicle is in an oblique position, due to lack of effective braking mechanisms.
Innovation Solution
A device with an electric or electromechanical drive, a control apparatus, a short-circuit-generating mechanism, a decision device, a sensor system, and a plausibility-checking device that generates a short-circuit to create a braking effect when unintended movement is detected, accompanied by a warning system to ensure safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a braking operation is implemented to prevent unintended movements of the closing part, then the safety and reliability are improved, but the device complexity and energy consumption increase
Solution Approach 1:
The drive system performs braking operations autonomously through self-service mechanisms. The control apparatus automatically detects unintended movements and activates the drive in braking fashion without requiring external intervention or complex additional braking systems. The drive itself generates the counter-pulse to counteract harmful movements, eliminating the need for separate braking apparatus.
Solution Approach 2:
The drive system serves multiple functions: it normally actuates the closing part for opening/closing operations, and simultaneously provides braking capability when unintended movements are detected. By making the drive multi-functional, the patent avoids adding separate dedicated braking mechanisms, thus reducing device complexity while maintaining safety.
2Reliability
If a braking operation is implemented to prevent unintended movements of the closing part, then the safety is improved, but the energy consumption increases
Solution Approach 1:
The braking operation is activated periodically or intermittently only when unintended movements are detected, rather than continuously. The control apparatus monitors the movement of the closing part and activates the drive in braking fashion only when deviations from the setpoint movement sequence are detected, reducing unnecessary energy consumption while maintaining safety when needed.
Solution Approach 2:
The drive system generates its own braking action through self-service by detecting its own unintended movements and activating counter-pulses accordingly. This self-regulating mechanism avoids the need for continuous external energy input or complex energy management systems, reducing overall energy consumption while maintaining safety.
3Reliability
If the drive is actuated to become active in braking fashion, then the unintended movements are prevented, but the device complexity increases due to additional control mechanisms
Solution Approach 1:
The control apparatus uses feedback from the sensor system to monitor the actual movement of the closing part and compares it with the setpoint movement sequence. When deviations are detected, the feedback mechanism triggers the drive to become active in braking fashion. This feedback-based control simplifies the overall system by using the existing drive and control apparatus rather than requiring separate complex braking control systems.
Solution Approach 2:
The control apparatus performs self-monitoring and self-correction by detecting its own deviations from the intended movement sequence and automatically activating the drive in braking fashion. This self-service approach reduces control complexity by eliminating the need for external monitoring systems or separate braking control mechanisms.

AI summary
A device for operating a closing part, driven by a drive, on a device of transportation contains a control apparatus which is assigned to the drive and is configured to actuate the drive in order to initiate a measure which is opposed to the movement of the closing part. The drive is embodied as an electric or electromechanical drive. The drive can be actuated by the control apparatus in such a way that the drive becomes active in a braking fashion with respect to the movement of the closing part.
