Frame-Like Crossing Moulded Body With Functional Insert Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Service level crossings in non-public areas, such as factory premises or station connections, require a molded body for track crossing devices that can integrate additional functions like water drainage, moisture evaporation, and information display, while maintaining structural integrity and ease of maintenance access.
Innovation Solution
A molded body for track crossing devices is designed with a frame-like base body made of elastic material, featuring a base body opening for insert elements that can be securely fixed, allowing for thin insert elements and supporting structures that facilitate water drainage, information display, and maintenance access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a solid base body is used without openings, then structural strength is improved, but additional functions (drainage, evaporation, information display) cannot be integrated
Solution Approach 1:
The base body is segmented by introducing openings that completely penetrate from the upper side to the underside, dividing the solid structure into regions that allow functional insert elements while maintaining overall structural integrity through the frame-like design
Solution Approach 2:
The base body with openings is designed to accommodate multiple types of insert elements that can provide different functions (drainage, evaporation, information display), making the track crossing device versatile and adaptable to various operational requirements
2Length of moving object
If the base body support surface is positioned close to the top, then thin insert elements can be used, but support stability may be compromised
Solution Approach 1:
The base body support surface is positioned at a specific location (distance less than 50% of base body height from the top) to provide optimal support for thin insert elements, creating a localized support zone that balances insert element thickness requirements with support stability
Solution Approach 2:
The base body is designed with a predetermined support surface position and frame-like structure that pre-establishes stable support conditions for insert elements, ensuring stability is built into the design rather than added later
3Adaptability or versatility
If openings are added to the base body, then functional versatility is improved, but structural integrity deteriorates
Solution Approach 1:
The base body is designed as a frame-like structure with openings that segment the solid material while maintaining the overall structural framework, allowing functional insert elements to be integrated without compromising the base body's structural integrity
Solution Approach 2:
The track crossing device combines the base body made of elastic material with insert elements made of different materials (metal, plastic, composite), creating a composite structure that leverages the strengths of each material for both structural integrity and functional versatility

AI summary
A molded body for a level crossing device comprises a base body (24) constructed of elastic material, with a base body underside (42) to be positioned facing a track system and a base body upper side (40) arranged at a distance in a base body vertical direction (H) from the base body underside (42) and to be positioned facing away from a track system, wherein the base body (24) is designed in a frame-like manner and surrounds at least one base body opening (38) that completely penetrates the base body (24) from the base body upper side (40) to the base body underside (42), wherein at least one insert element (28) is received in the at least one base body opening (38) and is fixed to the base body (24) against detachment from the base body (24).wherein a base body support surface is provided on the base body (24) offset in the vertical direction (H) of the base body towards the bottom (42) for supporting an insert element support edge (50) provided on the at least one insert element (28), wherein a distance (A) of the base body support surface to the base body top (40) is less than 50% of a maximum distance (D) between the base body top (40) and the base body bottom (42) in the vertical direction (H) of the base body and/or a thickness (d) of the insert element support edge (50) in the vertical direction (H) of the base body is less than 50% of the maximum distance (D) between the base body top (40) and the base body bottom (42) in the vertical direction (H).
