Rail Carriage Coupling Fixing Device Direct Longitudinal Beam Mount
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rail vehicle car body designs require numerous and heavy power transmission elements to manage coupling forces, which occupy significant space and complicate installation, especially when space is limited beneath the car body.
Innovation Solution
The car body design features a coupling fastening device connected directly to longitudinal beams on either side, allowing for direct force transmission and reducing the need for additional support elements, thereby minimizing the number and mass of power transmission elements required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If traditional coupling mounting devices are used with multiple support elements, then coupling forces can be transmitted, but the number and mass of power transmission elements increase, occupying significant space and complicating installation
Solution Approach 1:
The patent combines multiple support elements into a single integrated support structure that connects the coupling mounting device to the longitudinal beams. This merging reduces the number of separate power transmission elements while maintaining the ability to transmit coupling forces effectively, thereby reducing device complexity and freeing up space beneath the car body floor
Solution Approach 2:
The integrated support structure serves multiple functions simultaneously: it provides structural support, transmits coupling forces, and creates space for other components. This multi-functionality reduces the need for additional dedicated support elements, simplifying the overall device while maintaining force transmission capability
2Force
If traditional coupling mounting devices are used with multiple support elements, then coupling forces can be transmitted, but the mass of power transmission elements increases
Solution Approach 1:
By merging multiple support elements into a single integrated structure, the total mass of power transmission elements is reduced. The integrated design eliminates redundant materials and connections while maintaining the structural integrity needed for coupling force transmission
3Force
If traditional coupling mounting devices are used, then coupling forces can be transmitted, but significant space is occupied beneath the car body floor
Solution Approach 1:
The integration of support elements into a compact single structure significantly reduces the volume occupied beneath the car body floor. This space reduction allows for better routing of cables, hydraulic lines, and positioning of other components in the available space
4Force
If traditional coupling mounting devices are used with multiple support elements, then coupling forces can be transmitted, but installation becomes more complicated
Solution Approach 1:
The integrated support structure can be manufactured as a single component or pre-assembled unit, significantly simplifying the installation process compared to installing multiple separate support elements. This merging reduces the number of assembly steps and potential error sources during installation
