Glass Railing Holder Wedge Profile for Stable Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glass railing holding arrangements face challenges in achieving stable and accurate vertical fixation of glass panels, with limitations in stability and adjustability, often requiring specialized support profiles and narrow foot areas for fixation.
Innovation Solution
The solution involves separate wedge profile parts with simple, non-cambered fixing wedges and a foot fixation mechanism using a wedge block guided on the wedge profile part, allowing for a stable and defined mounting of the glass pane within a U-shaped support profile, which can be of any construction, such as welded steel, and includes features like undercut guide grooves and corrugated surfaces for enhanced stability and assembly aids like spacers for centering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wedge fixing arrangement is used to hold the glass pane, then the glass pane can be secured in the support profile, but the vertical fixation accuracy and stability are insufficient
Solution Approach 1:
The wedge profile part is divided into separate functional elements: contact legs for positioning, fixing wedges for clamping, and a wedge block for vertical adjustment. This segmentation allows each element to be optimized independently for its specific function, improving both stability and precision.
Solution Approach 2:
The wedge fixing arrangement is designed to be self-aligning and self-adjusting. The wedge block can move vertically within the wedge profile part to automatically compensate for tolerance variations in the glass pane, achieving accurate vertical fixation without additional adjustment mechanisms.
2Reliability
If a specialized support profile with actuating screws is used, then the glass railing can be held, but the system becomes complex and cannot be universally applied to different support profile constructions
Solution Approach 1:
The wedge fixing arrangement is extracted from the support profile itself and implemented as a separate, independent component. This allows the support profile to remain simple and universal (U-shaped cross-section), while the removable wedge profile parts provide the necessary fixing functionality for any glass pane thickness or material.
Solution Approach 2:
The wedge profile part is designed as a universal component that can be applied to any U-shaped support profile regardless of the specific construction material (steel, aluminum, etc.). The same wedge profile part works with different glass pane thicknesses and can be installed on various building parts (balconies, stairs, terraces).
3Ease of manufacture
If the glass pane is held only at its base area with two wedge blocks, then the fixation is simple, but the stability and load distribution are insufficient
Solution Approach 1:
The fixing system transitions from holding the glass pane only at the base (one dimension/level) to distributing fixation forces along the entire lower edge zone (two dimensions). The wedge profile part engages with both inner and outer edge zones, creating a distributed fixation system that improves stability while maintaining simplicity.
4Reliability
If corrugated contact surfaces and cambered wedge surfaces are used, then the holding force and resistance to loosening are improved, but the manufacturing complexity increases
Solution Approach 1:
The wedge profile part uses standardized corrugation parameters (ridge spacing, depth) and camber radii that are optimized for maximum holding force. These parameters are selected during design to achieve the required mechanical performance while remaining compatible with standard manufacturing processes for extruded or formed profiles.

Function Achieved in This Case
This configuration ensures a permanently stable and accurately aligned glass panel mounting, allowing for angle correction and tolerance compensation, with improved holding force and resistance to loosening, while enabling flexible and sealed support of the glass pane.
Implementation Method 1
The mutually facing contact surfaces of the guide groove and the guide web are provided with intermeshing teeth to block the relative displacement of wedge profile part and wedge block
Implementation Method 2
The mutually facing contact surfaces of the guide groove and the guide web are provided with intermeshing teeth to block the relative displacement of wedge profile part and wedge block in their clamped position
