Glued Glass Movable Panel Frame System for Torsion Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing framing systems for windows and doors impose structural limitations on glass dimension and weight due to the need for glass to be inserted or laid down, restricting the size and weight of movable panels for safety reasons.
Innovation Solution
A framing system where the glass is glued to the movable panel, becoming a structural component, allowing larger spans and increased weight capacity, while eliminating torsion and optimizing mechanical behavior and thermal, acoustic, and wind performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If glass is inserted or laid down inside a movable panel, then safety requirements are met, but the dimension and weight of the movable panel are limited
Solution Approach 1:
The patent merges the glass with the movable panel by structurally integrating them into a single composite unit. The glass is positioned within a recess of the panel and bonded using adhesive, creating a unified structure where the glass becomes an integral part of the movable panel rather than a separate inserted component. This merging allows the assembly to function as a single structural unit, enabling larger dimensions and greater weight capacity while maintaining safety.
Solution Approach 2:
The patent creates a composite structure combining glass and the movable panel material (typically aluminum or other metals) into a unified assembly. The glass is bonded to the panel using adhesive, forming a composite unit that leverages the strengths of both materials - the structural integrity of the panel and the transparency/strength of the glass - enabling larger spans and improved mechanical behavior.
2Ease of manufacture
If glass is inserted or laid down inside a movable panel, then assembly is simple, but torsion of the monolithic panel block occurs
Solution Approach 1:
The patent merges the glass with the movable panel through structural integration and adhesive bonding, creating a unified composite structure. This merging eliminates the separation between glass and panel that causes torsion, as the bonded interface creates a rigid connection that prevents relative movement and twisting of the panel block during operation.
3Length of moving object
If glass is glued to the movable panel, then larger spans are enabled, but the structural complexity increases
Solution Approach 1:
The patent merges the glass and panel into a unified composite structure through adhesive bonding, eliminating the need for separate retention mechanisms such as clips, gaskets, or mechanical fasteners. This merging simplifies the overall structure by reducing the number of discrete components while enabling larger spans, as the bonded joint provides sufficient structural continuity for extended dimensions.
Solution Approach 2:
The patent extracts and eliminates unnecessary intermediate components from traditional assembly schemes. Instead of using multiple separate elements (retention clips, gaskets, mechanical fasteners), the invention uses direct adhesive bonding to join the glass to the panel, removing extraneous parts and simplifying the structure while maintaining or enhancing structural performance.
4Quantity of substance
If traditional assembly scheme is used, then aluminium usage is higher, but the band size is larger
Solution Approach 1:
The patent extracts and removes excess aluminium from the profile structure by eliminating the need for thick retention features, clips, and mechanical fastening elements. The adhesive bonding system requires minimal aluminium infrastructure, allowing the profile dimensions to be reduced while maintaining structural integrity, thus reducing both material usage and external dimensions.

AI summary
The present invention consists of an improved framing system for doors or windows, fixed panels and modular composite spans, by means of which an exterior minimalist aspect can be executed. The present invention comprises at least one fixed rim (7) and at least one movable panel (8) in which the glass (4) is glued to the movable panel (8), instead of being merely laid down or inserted, thus being part of the structural component of the movable panel (8) and making it possible to manufacture larger spans, so that one can have, for example, larger swinging windows. The invention also comprises fixation chambers for fixing squares (1), located in the fixed rim (7); polyamide thermal cutting elements (2); ironmongery (5) and elements for mechanically retaining the glass (4) from the outside of the movable panel (8). This structural innovation, the gluing of the glass (4), has the additional advantage of eliminating the torsion of the monolithic panel block; it also optimises the system's mechanical behaviour and makes the functional performances more reliable by improving the functionality of the manoeuvring accessories, allowing an increase in the lifespan of the wearing accessories.
