Angled Screw Glass Holder for Constant Frame Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glazing systems for fixed windows, particularly in passive houses, face issues with maintaining tightness over time due to shrinkage in wooden parts and loss of contact pressure, leading to potential leaks.
Innovation Solution
A method for attaching a glass pane to a frame using a glass holder that exerts a constant contact pressure via a screw guide with an angled entry and a two-part sliding body mechanism, ensuring reliable fixation and tightness, and allowing for easy installation from the inside without damaging the glass pane.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If wooden parts are used in the frame structure, then the frame provides good structural support and aesthetics, but shrinkage occurs over time causing loss of contact pressure and tightness
Solution Approach 1:
A compression element (spring or elastomeric member) is introduced as an intermediary between the glass holder and the frame. This mediator maintains constant contact pressure on the glass stop even when the wooden frame shrinks, transferring the fastening force through the compression element to ensure continuous tightness without requiring the wooden frame itself to maintain constant pressure.
2Reliability
If glass panes are fastened from the outside of the building, then proper fixation can be achieved, but scaffolding is required which increases cost and complexity
Solution Approach 1:
The fastening operation is inverted from outside-to-inside to inside-to-outside. The glass holder is attached to the inner surface of the frame, and the fastening element (screw or clip) is inserted and secured from the interior side of the building. This allows installation without external scaffolding while maintaining secure fixation of the glass pane.
3Reliability
If conventional glazing methods are used, then glass panes can be installed, but the assembly process is complex and time-consuming
Solution Approach 1:
The glass holder is pre-assembled with the glass pane and the compression element before installation. The holder is designed as a pre-fabricated unit that includes the fastening mechanism and sealing components. This preliminary assembly reduces on-site installation steps and time while ensuring proper configuration for reliable glazing.

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 reliable, long-lasting, and cost-effective mechanical fixation of glass panes, ensuring tightness and eliminating the need for external installation, thus preventing leaks and simplifying the assembly process.
Implementation Method 1
each sliding body part having a sliding surface designed as an inclined plane, which slide on one another and one sliding body part is provided in the glass holder body and the other sliding body part is designed as a screw guide

AI summary
The invention relates to a method for fastening or fixing a glass pane (2) or a sheet-like structure in a frame (3), in particular for fixed glazing units. The frame (3) has an outer glass stop (4) with a smaller clear width than the glass pane (2), on which stop the glass pane (2) is placed, if appropriate via a seal (19). After placing the glass pane (2) on the glass stop (4), there is arranged at least one glass holder (1) which lies on the surface of the frame (3) and bears by way of a pressing face (5) against the glass pane (2) at the edge region of the latter. This glass holder (1) has a bore (6) which is provided at an angle (a) to the glass plane and is intended for a screw (7), wherein the fastening of the glass pane (2) is effected via the glass holder (1) and a contact pressure on the outer glass stop (4) is produced by the screw (7) which is provided in the glass holder (1), is guided obliquely via the bore (6) and is screwed into the frame (3).
