Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport devices for rail vehicles struggle to navigate curves at high speeds without derailing, especially when transporting vehicles with different track gauges, due to increased wheelbase and approach angles that restrict cornering ability and increase the risk of derailment.
Innovation Solution
The transport device features longitudinal support elements with recesses and wheel receiving elements that allow for adjustable wheel positioning, providing play in the X-direction to accommodate various wheel sizes and gauges, ensuring secure fit and rotation, and includes a frame design with U-shaped recesses and spring elements for enhanced stability and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the wheelbase is increased to support multiple axles for transporting rail vehicles, then the load-bearing capacity is improved, but the ability to negotiate curves deteriorates
Solution Approach 1:
The transport device employs a dynamic suspension system with spring elements (element 20) that allow the longitudinal support elements to move relative to the frame. This dynamic capability enables the wheelbase to adapt during curve negotiation, reducing the effective wheelbase angle and improving cornering ability while maintaining the extended wheelbase structure for load-bearing capacity.
2Stability of the object's composition
If the wheelbase is increased to support multiple axles, then the stability is improved, but the approach angle increases which reduces cornering ability
Solution Approach 1:
The suspension system with spring elements enables the longitudinal support elements to dynamically adjust their position, reducing the approach angle during curve negotiation while maintaining the stable extended wheelbase structure for transporting rail vehicles.
Solution Approach 2:
The invention changes the geometric parameters of the transport device by allowing the longitudinal support elements to shift position relative to the frame, effectively reducing the approach angle and wheelbase angle during cornering operations while maintaining the extended wheelbase configuration.
3Device complexity
If the transport device is designed with fixed wheel positioning, then the structural simplicity is maintained, but the adaptability to different track widths deteriorates
Solution Approach 1:
The longitudinal support elements are designed to move longitudinally within the frame structure, allowing dynamic adjustment of the wheel positioning to accommodate different track widths while maintaining a relatively simple overall structural design.
Solution Approach 2:
The transport device is designed with universal adaptability to handle different rail vehicle gauges by allowing the longitudinal support elements to adjust their position, enabling a single device design to serve multiple track width requirements.
4Manufacturing precision
If the transport device uses a rigid frame structure, then the manufacturing precision is improved, but the flexibility to accommodate wheel movement deteriorates
Solution Approach 1:
The invention introduces controlled dynamic elements (spring suspension) into the rigid frame structure, allowing the longitudinal support elements to move relative to the frame while the frame itself maintains high manufacturing precision and structural integrity.
