Track Transition Drainage Mould With Integrated Flow Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing track crossing devices struggle with the uncontrolled drainage of water accumulating in track groove recesses, leading to inefficiencies and potential waterlogging issues.
Innovation Solution
A drainage molded body with orthogonal track groove recesses and drainage channels that direct water to drainage openings, featuring a constant gradient and V-shaped channel base to facilitate efficient water flow, along with a diverting element to align with drainage pipes, ensuring uniform drainage even with misalignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If track groove recesses are provided in rail contact end regions to prevent contact with wheel rims, then wheel rim contact is prevented, but water accumulates in the groove recesses causing uncontrolled water flow and potential waterlogging
Solution Approach 1:
The drainage channel extracts water from the groove recess and transports it to a discharge location away from the track system. By separating the water removal function from the groove structure, the harmful water accumulation effect is eliminated while preserving the wheel rim protection function of the groove.
Solution Approach 2:
The drainage channel acts as an intermediary element between the groove recess (where water accumulates) and the external environment. This mediator provides a controlled pathway for water to leave the groove system, preventing uncontrolled drainage while maintaining the groove's primary function.
2Reliability
If drainage channels are added to direct water flow, then water drainage is improved, but device complexity increases
Solution Approach 1:
The drainage channel is merged with the track transition device body, forming an integrated structure. The channel is formed as part of the molded body rather than being a separate component, which reduces overall device complexity while maintaining effective water drainage functionality.
Solution Approach 2:
The track transition device is designed with multi-functionality: it provides wheel rim protection through groove recesses, structural support through the molded body, and water drainage through integrated channels. By combining multiple functions into a single device, the need for separate drainage components is eliminated.
3Productivity
If drainage openings are positioned to align with drainage pipes, then drainage efficiency is maximized, but installation precision requirements increase
Solution Approach 1:
The drainage opening extends in the vertical direction (third dimension) rather than only in the horizontal plane. This vertical extension creates a larger target area for alignment with the drainage pipe, reducing the precision requirements for installation while maintaining drainage efficiency.
Solution Approach 2:
The drainage opening has non-uniform geometry with different dimensions in different directions. By optimizing the opening shape (extending vertically), the design compensates for potential misalignment in horizontal positioning, allowing efficient drainage even with moderate installation variations.

AI summary
A drainage molded body for a track crossing device comprises two track end regions arranged at a distance from each other in a transverse direction of the molded body, wherein at least one, preferably each, track end region provides a groove recess (46, 48) extending substantially in a longitudinal direction of the molded body orthogonal to the transverse direction of the molded body, further comprising at least one drainage channel (52) extending from the at least one groove recess (46, 48) to at least one drainage opening (54).
