Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic coupling systems for rail vehicles require time-consuming visual inspection to determine the coupling state, which is inefficient and prone to errors, especially in large train sets, and offer limited visibility for intermediate positions.
Innovation Solution
A coupling head with integrated detection devices for the bolt holder and locking element positions, allowing for automated recognition of coupling states without additional mechanical displays, using sensors to detect and evaluate the positions of these components, enabling quick and accurate determination of 'ready for coupling', 'coupled', and 'uncoupled' states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If visual inspection with mechanical display is used to detect coupling state, then the system structure remains simple, but the detection process becomes time-consuming and error-prone
Solution Approach 1:
The patent replaces the mechanical visual inspection system with an automated sensor-based detection system. Sensors detect the position of the locking element and bolt holder, converting mechanical states into electrical signals for automated evaluation, thereby eliminating manual visual inspection while maintaining structural simplicity through electronic substitution
Solution Approach 2:
The coupling head performs self-detection of its own coupling state through integrated sensors that automatically monitor the position of its internal components (locking element and bolt holder). The system self-evaluates whether coupling is complete without requiring external visual inspection, enabling automated coupling processes
2Measurement precision
If mechanical display with lever element is used, then the display structure remains simple, but intermediate coupling positions cannot be recognized
Solution Approach 1:
The detection system is segmented into multiple independent sensors, each monitoring specific components (locking element position, bolt holder position). This segmentation allows detection of intermediate positions by evaluating the combined state of multiple components, providing precise coupling status information without requiring complex mechanical displays
Solution Approach 2:
The patent introduces sensors as intermediary elements between the mechanical coupling components and the evaluation system. These sensors act as mediators that translate mechanical positions into detectable signals, enabling precise detection of intermediate coupling positions that cannot be visually distinguished in mechanical displays
3Productivity
If automated coupling processes are implemented, then coupling efficiency improves, but the complexity of control technology increases
Solution Approach 1:
The system implements feedback by continuously monitoring the positions of the locking element and bolt holder through sensors, evaluating the coupling state, and using this information to control the coupling process. The feedback mechanism provides real-time status information enabling automated decision-making without requiring complex external control systems
Solution Approach 2:
The evaluation device performs multiple functions: detecting sensor signals, evaluating coupling state, determining intermediate positions, and controlling the coupling process. This multi-functionality consolidates control technology into a single universal device, reducing overall system complexity while maintaining high coupling efficiency
