Rotating Wedge Clamp for Uniform Railing Plate Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamping devices for railing plates, particularly in all-glass railings, face challenges in providing a flat structure with few components, easy assembly and operation, and controlled clamping force distribution without internal tensioning elements, while also requiring minimal space and allowing one-sided actuation for efficient fixing.
Innovation Solution
A clamping device with two interacting clamping parts that rotate relative to each other, utilizing wedge surfaces to increase the effective clamping width and generate clamping force, featuring a twisting mechanism and a tool attachment for easy operation, and an anti-twist device for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If internal tensioning screws are used to expand clamping wedge elements, then clamping force can be controlled and applied, but the device becomes complex and requires wide clamping wedges or special adaptations
Solution Approach 1:
The invention extracts and eliminates the internal tensioning screws and expansion mechanism from the clamping device. Instead of using internal clamping elements, the patent employs a simple clamping wedge that is driven directly into the clamping gap between the railing panel and support surface, achieving high clamping force without complex internal structures.
Solution Approach 2:
The invention inverts the traditional approach by using a wedge that is driven from the outside into the clamping gap, rather than using internal screws to expand wedges from within. This external drive-in approach simplifies the structure while maintaining effective clamping force application.
2Adaptability or versatility
If clamping wedges are made wide or specially adapted to accommodate internal clamping elements, then internal tensioning can be achieved, but the device requires more space and becomes less adaptable
Solution Approach 1:
By removing the internal tensioning elements, the patent enables the use of narrow clamping wedges that can be driven into tight clamping gaps without requiring additional space for internal mechanisms, thereby improving adaptability to various installation conditions.
3Force
If multiple individual elements are used in clamping wedge systems with internal clamping means, then clamping force can be distributed, but the number of components increases and assembly becomes more complex
Solution Approach 1:
The invention merges the clamping wedge and the force application mechanism into a single integrated component. The clamping wedge itself serves as both the structural element and the force-applying element, eliminating the need for separate tensioning screws, nuts, and other internal clamping components.
Solution Approach 2:
While reducing the number of components, the patent maintains effective force distribution through the wedge geometry itself, which naturally distributes clamping force along its contact surfaces with the railing panel and support structure.
4Area of stationary object
If drive-in wedge systems are used to minimize space requirements, then narrow clamping gaps can be accommodated, but internal tensioning elements require accessibility from outside
Solution Approach 1:
By eliminating internal tensioning elements entirely, the patent resolves the accessibility conflict. The clamping wedge is driven into the gap using a simple tool applied to the wedge's drive end, with no subsequent accessibility requirements for internal components, as the wedge self-locks through its wedge geometry.
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
The solution provides a compact, easy-to-assemble clamping device that effectively distributes clamping force along the railing plate, ensuring reliable fixation with minimal components and no internal tensioning elements, allowing one-sided operation and secure clamping without complex structures.
Implementation Method 1
At least one of the two clamping parts has one or more wedge surfaces pointing towards the other clamping part, on which the other clamping part slides when rotated.
Implementation Method 2
the interacting first and second wedge surfaces are directly opposite one another in the assembly orientation and either are in contact with one another or stand or come into contact with each other by twisting in the direction of clamp orientation

AI summary
The invention relates to a clamping device for the clamping fixation of railing panels in a railing panel receptacle. Without the need for internal clamping elements, a clamping device that is easy to mount and can be uniformly metered along the railing panel is provided by rotating the clamping elements of the device relative to each other when the clamping device is positioned within the clamping gap to generate the clamping force.
