Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems for attaching glass panels to substructures in skylights, window walls, and greenhouses are heavy, expensive, complex, and aesthetically undesirable, lacking design flexibility.
Innovation Solution
A system that mounts glass panels directly onto structural elements, eliminating the need for aluminum substructures, using a blocking with flashing and elastic gaskets to secure the panels, reducing weight, cost, and complexity while allowing for a slim line architectural appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If an aluminum intermediate substructure is used to support glass panels, then the system provides structural support and stability, but the weight, cost, and complexity increase significantly
Solution Approach 1:
The patent removes the intermediate aluminum substructure from the conventional system, attaching glass panels directly to the steel structural elements. This extraction eliminates the unnecessary aluminum framing while maintaining structural support through direct attachment mechanisms including blocking, flashing, and gasket systems that connect glass directly to the load-bearing steel structure.
Solution Approach 2:
The patent merges the functions of multiple separate components (aluminum substructure, blocking, flashing, gaskets) into a streamlined direct-attachment system. The blocking, flashing, and gasket assembly work together as an integrated system that provides both structural support and weather sealing in a single configuration, eliminating the need for separate aluminum framing.
2Strength
If an aluminum intermediate substructure is used to support glass panels, then the system provides structural support, but the aesthetic appearance deteriorates due to visible framing
Solution Approach 1:
The patent removes the visually prominent aluminum framing from the exterior appearance by attaching glass panels directly to the structural elements. This extraction of the intermediate substructure allows for sleek, minimalistic architectural lines where the glass panels appear to be directly supported by the building structure, creating a cleaner aesthetic.
3Strength
If an aluminum intermediate substructure is used to support glass panels, then the system provides structural support, but the device complexity increases
Solution Approach 1:
The patent simplifies the system by removing the complex aluminum intermediate substructure and its associated connection details. The direct-attachment system uses a more straightforward sequence of components (blocking attached to structure, flashing over blocking, gaskets on flashing, glass on gaskets) that reduces the number of connection points and assembly steps compared to conventional aluminum framing systems.
4Device complexity
If glass panels are mounted directly onto structural elements, then weight, cost, and complexity are reduced, but the reliability of water infiltration prevention must be maintained
Solution Approach 1:
The patent incorporates flashing that extends beyond the blocking to create an overlapping weather barrier system before the glass panels are installed. The flashing is positioned to direct water away from the blocking-glass interface, and the gaskets are pre-positioned on the flashing to ensure proper sealing. This preliminary arrangement of protective elements ensures water infiltration prevention is built into the system design rather than added as an afterthought.
Solution Approach 2:
The patent uses elastic gaskets positioned between the flashing and glass panels to provide a compliant sealing layer that accommodates thermal expansion, contraction, and settlement movements. These gaskets act as a cushioning element that maintains the weather seal under varying environmental conditions, preventing water infiltration paths that could develop through rigid connections.

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 reduces weight, cost, and complexity while enhancing aesthetics and design flexibility by allowing direct attachment of glass panels to structural elements, creating a thermally-broken glazing system that prevents water infiltration.
Implementation Method 1
A first elastic flange gasket covers an outer edge of the first flange... A first glazing cap extending along a length of the blocking and having a first elastic cap gasket for contacting the outer main surface of the first glass panel
Implementation Method 2
a blocking extending along a length of a structural element, the blocking attached to a first portion of a surface of the structural element
Implementation Method 3
A flashing covers the blocking, the flashing having a first flange extending outward from a lower edge of the blocking proximal the first portion of the surface of the structural element, to contact a second portion of the surface of the structural element not in contact with the blocking
Data Source
AI summary
A system and method is provided for attaching glass panels to a substructure. Embodiments include a blocking extending along a length of a structural element and attached to a first portion of a surface of the structural element. Flashing covers the blocking, and has a flange extending outward from a lower edge of the blocking to contact a second portion of the surface of the structural element. An elastic flange gasket covers an outer edge of the flange and contacts an inner main surface of a glass panel. A glazing cap extends along the blocking, having an elastic cap gasket for contacting the outer main surface of the glass panel. The glazing cap extends over and attaches to the blocking for retaining the glass panel between the flange gasket and the cap gasket, and for sealing the glass panel, the flange gasket, and the cap gasket.
