Freight Wagon Height Compensation Interface for Load Weight Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current freight wagons face limitations in utilizing the full potential of the railway gauge due to variations in load weight and wheel wear, leading to inconsistent and suboptimal height adjustments, which restrict the ability to transport loads efficiently within the gauge constraints.
Innovation Solution
Incorporating height compensation interfaces between the end railway assemblies and the connecting structure, allowing for adjustable height settings based on load weight and wagon condition to maintain a constant or near-constant distance from the ground, thereby optimizing the use of the railway gauge's lower limit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the wagon's suspension and structure are designed for the heaviest loads to achieve maximum lower level clearance, then the lower clearance limit is optimized for heavy loads, but lighter loads result in higher than necessary clearance levels reducing available height
Solution Approach 1:
The patent applies the dynamics principle by making the connecting structure's lower level adjustable rather than fixed. The height compensation interface allows the structure to dynamically adapt its position based on load weight, enabling the wagon to maintain optimal clearance levels whether carrying heavy or light loads. This resolves the contradiction by transforming a static design into a dynamic one that responds to varying conditions.
Solution Approach 2:
The patent implements parameter changes by modifying the height parameter of the connecting structure's lower level. The height compensation interface enables adjustment of this critical parameter according to the load weight, allowing the wagon to optimize its clearance level for each specific loading condition. This directly addresses the contradiction by making the clearance level a variable parameter rather than a fixed design value.
2Volume of moving object
If the wagon maintains a constant low lower level for all loads, then maximum upward clearance is available within the gauge, but the wagon cannot accommodate variations in load weight and suspension deformation
Solution Approach 1:
The patent applies feedback by using the load weight information to adjust the lower level position. The height compensation interface responds to the actual loading conditions and adjusts the connecting structure's position accordingly, creating a feedback loop that maintains reliability of the lower level position while allowing the upper space to be maximized. This resolves the contradiction by introducing active adjustment based on real-time conditions.
Solution Approach 2:
The patent makes the lower level position dynamic rather than fixed. The height compensation interface enables the connecting structure to adjust its position based on load conditions, allowing the system to maintain reliability (consistent optimal positioning) while maximizing available upper space. This dynamic adjustment capability resolves the contradiction between constant low level and accommodation of variations.
3Volume of moving object
If the railway wheel radius is reduced due to wear and reprofiling, then the wagon's height is lowered, but the lower level may fall below the permissible limit of the railway gauge
Solution Approach 1:
The patent applies preliminary action by adjusting the lower level position in advance to compensate for expected wheel wear and reprofiling. The height compensation interface allows pre-adjustment of the connecting structure's position, ensuring that even when wheel radius decreases, the lower level remains within permissible gauge limits. This resolves the contradiction by proactively compensating for future changes.
Solution Approach 2:
The patent makes the lower level position adaptable to wheel condition changes. The height compensation interface enables adjustment of the connecting structure to maintain compliance with gauge limits regardless of wheel radius variations. This dynamic adjustment capability resolves the contradiction between maximizing usable volume and maintaining precision compliance with gauge limits.

AI summary
The invention relates to a transport wagon (1) for transporting at least one load which includes a linking structure (2) and two end rolling rail assemblies (3) and (4) on which the latter rests, characterised by having at least one interface (32) for adjusting the height of the lowest portion of the wagon between the end assemblies (3) and (4), mainly according to the weight of the load to be transported and the condition of the wagon, in order to obtain for each load an almost-constant low level of the low portion that exists between the end assemblies and, in particular, the lowest acceptable level according to the rail gauge. The invention is useful for manufacturers of wagons for general freight transport as well as for intermodal transport, for example rail/road.
