Flush-Mounted Vehicle Window Clamping for Easy Pane Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle window arrangements with clamping systems, particularly those using keder elements, often protrude outward, compromising the aesthetic flush fit between the window pane and the vehicle body, and are difficult to replace without complex screw connections or adhesive removal.
Innovation Solution
A vehicle window arrangement featuring a recessed clamping system with a keder element that is fully or partially inserted into a clamping profile, ensuring both components remain within the vehicle's outer contour, allowing for a flush fit and easy replacement without screws or adhesives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a clamping system with keder element is used to secure the window pane, then the window pane can be firmly fixed and easily replaced, but the clamping system protrudes outward and compromises the aesthetic flush fit between the window pane and the vehicle body
Solution Approach 1:
The keder element is inserted into the clamping profile, with the keder element being nested within the clamping profile structure. This nesting arrangement ensures that the securing mechanism is hidden within the overall clamping system boundary, allowing the outer surface of the clamping profile to remain flush with the vehicle body while the keder element provides the necessary securing function internally.
2Ease of operation
If the clamping profile is widened to accommodate the window pane, then the window pane can be inserted, but the pane can easily slip out without additional securing
Solution Approach 1:
The clamping profile is pre-designed with a widenable receiving gap that can be opened to accommodate the window pane during installation. After the pane is inserted, the receiving gap is closed and locked by the keder element, which is inserted into the clamping profile to prevent the pane from slipping out. This preliminary design of the widenable gap facilitates easy insertion while the subsequent locking action ensures secure retention.
3Reliability
If screws or adhesive are used to fasten the window, then the window is securely fixed, but replacement becomes complex and time-consuming
Solution Approach 1:
The clamping system is designed as a segmented, modular structure consisting of a clamping profile and a separate keder element. The keder element can be independently inserted into the clamping profile to secure the window pane. This segmentation allows the window to be securely fixed during installation while enabling easy replacement by simply removing the keder element, without requiring complex screw connections or adhesive removal processes.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables an aesthetically pleasing, easily replaceable window arrangement with a flush fit between the window pane and the vehicle body, eliminating outward protrusions and simplifying the installation process.
Implementation Method 1
The clamping profile is positioned between the window pane and the vehicle body and can be widened to accommodate the window pane
Implementation Method 2
a keder element can be inserted into the clamping profile after the pane has been inserted, thus securing and rigidifying it

AI summary
The invention relates, among other things, to a vehicle window arrangement for a rail or commercial vehicle, comprising a window pane which is arranged with an outer surface substantially flush with an outer surface of the car body of the rail or commercial vehicle surrounding it, wherein the window pane is fixed to the car body by means of a clamping system consisting of a clamping profile, in particular made of rubber, and at least one keder element which can be inserted at least partially into the clamping profile, characterized in that a circumferential auxiliary frame cooperating with the clamping system is attached to the window pane, which is arranged at a distance from the outer surface of the window pane, in particular projecting beyond the edge of the window pane, wherein neither the clamping profile nor the at least one keder element inserted into the clamping profile project outwards beyond the outer surface of the window pane.
