Pane Module Border Element for Window Glazing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional window glazing methods require numerous parts and can cause destructive strains on panes, leading to breakage and sealing failures, while gluing technologies face challenges with adhesion failure, environmental sensitivity, and lack of standardized design criteria, limiting their widespread adoption.
Innovation Solution
A method involving a border element that provides continuous support to the pane by attaching it to the window frame using screws or moulding, eliminating the need for glazing clips and adhesive, and allowing for improved load distribution and insulation properties without the use of glue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional glazing profiles with screws and clips are used to secure the pane, then the pane can be firmly attached to the frame, but the discontinuous support causes destructive strains on the pane leading to breakage and sealing failures
Solution Approach 1:
The invention merges the border element with the pane assembly to create an integrated unit. The border element is attached to the pane edges and extends to form a continuous support structure that integrates with the frame, eliminating the need for separate clips and screws that cause discontinuous support and stress concentration points.
Solution Approach 2:
The border element is pre-attached to the pane edges before installation into the frame. This preliminary attachment creates a continuous support system that distributes loads evenly across the entire pane perimeter, preventing the destructive strains that occur with post-installation mechanical fastening methods.
2Strength
If glazing clips and multiple parts are used for conventional glazing, then the pane can be secured to the frame, but the large number of different parts increases device complexity and potential failure points
Solution Approach 1:
The invention combines multiple separate components (border element, clips, screws, sealings) into a single integrated border element structure. This border element is attached to the pane edges and extends to form a continuous support that integrates with the frame, reducing the assembly to essentially one main component instead of multiple separate parts.
Solution Approach 2:
The border element serves multiple functions simultaneously: it provides mechanical support, creates sealing, enables frame attachment, and distributes loads. This multi-functionality eliminates the need for separate dedicated components for each function, thereby reducing overall device complexity.
3Reliability
If adhesive is used to attach the pane to the frame, then continuous support is achieved, but the glued connection is sensitive to environment and preparation conditions requiring special training and control systems
Solution Approach 1:
The invention replaces the chemical bonding mechanism of adhesives with a mechanical attachment system. The border element is mechanically attached to the pane edges and frame, providing continuous support through physical connection rather than chemical adhesion, thereby eliminating sensitivity to environmental conditions and surface preparation requirements.
Solution Approach 2:
The border element structure is designed to self-align and self-support during installation. The continuous support is achieved through the inherent geometry and attachment mechanism of the border element itself, without requiring external control systems, climate control, or specially trained personnel to ensure proper adhesive application.

AI summary
The pane module comprises a pane element composed by glass sheets (31, 35) and provided with a border element (37, 38) by moulding. The border element is adhered to the pane element during the moulding process and at least partially encases the border of at least one sheet element.
