Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing triple glazed windows with channel-section glazing elements suffer from limited transparency and thickness, and there is a need for improved energy performance and simplified production/installation in glazing applications.
Innovation Solution
A glazing unit comprising first and second channel-section glazing elements with an inner glazing element positioned between them, where the inner element's edge portion is compressed to form a seal and enhance thermal insulation, using materials like polyvinyl chloride, silicone rubber, or fibre insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If traditional triple glazed windows with planar glass sheets are used, then structural simplicity is maintained, but energy performance and thermal insulation are insufficient
Solution Approach 1:
The glazing is divided into multiple functional layers: outer channel-section glazing element, inner glazing element, and inner channel-section glazing element. Each layer serves specific functions - the outer element provides structural integrity and weather resistance, the inner element provides thermal insulation, and the innermost element provides additional protection and aesthetics. This segmentation allows optimization of each layer for its specific purpose, improving overall energy performance while maintaining manageable complexity through modular design.
2Stability of the object's composition
If channel-section glazing elements with flanges are used, then structural stability is improved, but visible transparency is reduced due to the profiled configuration
Solution Approach 1:
The channel-section glazing elements feature flanges at specific locations (lateral edges) rather than throughout the entire structure. The flanges are positioned only where structural support and sealing are needed, while the central portions of the glazing elements maintain maximum transparency. This localized application of structural features allows the glazing to achieve stability where required without compromising optical performance in the viewing areas.
3Loss of energy
If thick facades with multiple U-sections are used, then thermal insulation is improved, but the overall thickness of the glazing unit increases
Solution Approach 1:
The inner glazing element is nested within the cavity formed by the outer and inner channel-section glazing elements. The flanges of the channel-section elements interlock and nest together, creating a compact multi-layer structure. This nesting arrangement allows multiple functional layers to be integrated within a reduced overall thickness compared to traditional separate insulation panels, achieving improved thermal insulation without proportionally increasing the glazing unit thickness.
4Loss of energy
If complex multi-component glazing systems are used, then energy performance is improved, but production and installation complexity increases
Solution Approach 1:
The channel-section glazing elements serve multiple functions simultaneously: they provide structural support, create sealing cavities, offer thermal insulation through the nested inner element, and maintain weather resistance. The flanges are designed to perform both structural connection and sealing functions. This multi-functionality reduces the need for separate components, simplifying both production and installation while maintaining high energy performance.

AI summary
Glazings including first and second channel-section glazing elements arranged to define a cavity in which an inner glazing element is located are described. An end of a first flange of the first channel-section glazing element is spaced apart from a web of the second channel-section glazing element by a first space. The inner glazing element includes a central portion, a first edge portion running along a first side of the central portion, and a second edge portion running along a second opposite side of the central portion. A first portion of the first edge portion is positioned in the first space and is compressed by the end of the first flange of the first channel-section glazing element being positioned relative to the web of the second channel-section glazing element to form the first space.
