Rail Vehicle Floor C-Rail Insulation Sliding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rail vehicle floor construction methods face challenges in efficiently assembling and disassembling insulation layers on C-rails, often requiring fixed attachment methods that complicate manufacturing and installation processes.
Innovation Solution
The insulation layer is positively connected to the C-rail, allowing for sliding displacement and easy removal, with a form-fitting design that fills the C-cavity and extends beyond the C-legs for enhanced thermal insulation, using materials like open-cell or closed-cell integral foam, and avoiding load dissipation through the insulation layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the insulation layer is separately fixed in or on the C-rail by adhesive bonding, then the insulation layer is securely attached, but the assembly and disassembly processes become complicated and time-consuming
Solution Approach 1:
The patent replaces adhesive bonding (chemical connection) with a mechanical connection system consisting of a connection element with connection arms that engage with the C-rail. This mechanical system allows for easy assembly and disassembly while maintaining secure attachment, directly resolving the contradiction between attachment security and assembly complexity.
2Reliability
If the insulation layer is completely filled in the C-cavity and extends beyond the C-legs, then thermal insulation is enhanced, but the insulation layer becomes difficult to install and remove
Solution Approach 1:
The patent divides the insulation layer into two functional parts: a first section that fits within the C-cavity for thermal insulation, and a second section that extends beyond the C-legs and is connected to the connection element for installation/removal operations. This segmentation allows the insulation layer to provide enhanced insulation while remaining installable and removable through the connection mechanism.
Solution Approach 2:
The connection element acts as an intermediary between the insulation layer and the C-rail. It provides the mechanical engagement means that enable easy installation and removal of the insulation layer, even when the insulation layer is completely filled in the C-cavity and extends beyond the C-legs.
3Reliability
If adhesive bonding is used to fix the insulation layer, then the insulation layer is securely attached, but manufacturing technology and assembly processes become more complex
Solution Approach 1:
The patent replaces the complex adhesive bonding process with a simple mechanical connection system. The connection element with its connection arms provides a straightforward mechanical engagement with the C-rail, eliminating the need for adhesives and simplifying both the fixing mechanism and the overall assembly process.

AI summary
The invention relates to a floor or wall structure of a rail vehicle, comprising a support (1), wherein an upwardly open C-rail (2) is formed on the support (1) in its operational state, wherein the C-rail (2) is further connected to an insulating layer (9) providing thermal insulation, and, with respect to a cross-section, the insulating layer (9), in the case of an integral, material-seam design, both fills the C-cavity (7) and extends upwards beyond the C-legs (3, 4). To make the floor or wall structure particularly advantageous from a manufacturing perspective, it is proposed that the insulating layer (9) be connected to the C-rail (2) only by a positive fit, bearing on the C-legs (3, 4), and that the insulating layer (9) can be installed and/or removed by sliding it longitudinally along the C-rail (2).
