Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window units lose significant heat due to inadequate insulation, and current solutions for adding insulating airspaces are often complex to install, difficult to ensure a quality fit, and may interfere with window operability.
Innovation Solution
A window glazing assembly that includes an attachment assembly, such as a peel-and-stick double-sided tape, and one or more glazing panels or layers, which can be easily attached to existing window units to create additional insulating airspaces without compromising the window's operability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If additional insulating airspaces are added to window units, then thermal insulating capabilities are improved, but device complexity increases
Solution Approach 1:
The window assembly is divided into separate functional layers: existing window pane, attachment assembly with adhesive, spacer assembly, and additional glazing layer. This segmentation allows each component to be optimized independently and simplifies installation by allowing sequential assembly of manageable parts rather than handling a complex integrated unit.
Solution Approach 2:
The invention creates a nested structure where the attachment assembly is applied to the existing window, the spacer assembly is attached to the attachment assembly, and the additional glazing layer is attached to the spacer assembly. This nested arrangement allows multiple insulating airspaces to be created within a compact configuration without significantly increasing overall device complexity.
2Loss of energy
If complex assemblies are used to create insulating airspaces, then thermal performance is improved, but ease of operation deteriorates
Solution Approach 1:
By segmenting the insulating assembly into thin, flexible layers that can be applied separately to the window surface, the invention maintains the window's ability to move and operate. The segmented approach allows the window pane itself to remain free-moving while the insulating layers are applied to the frame or sash portions that do not need to move.
Solution Approach 2:
The attachment assembly and glazing layers use flexible adhesive films and thin glazing materials that can accommodate the movement and operation of the window. These flexible thin films maintain thermal insulation while allowing the window to open, close, and operate as intended without restriction.
3Loss of energy
If traditional insulating assemblies are installed, then thermal insulation is improved, but ease of manufacture deteriorates
Solution Approach 1:
The attachment assembly is pre-coated with adhesive in a manufacturing setting, and the spacer assembly is pre-fabricated with attachment surfaces. This preliminary preparation allows installers to simply apply the pre-prepared components to the window without needing to mix adhesives, cut custom pieces, or perform complex assembly procedures on-site, dramatically simplifying installation.
Solution Approach 2:
The invention merges multiple functions into integrated components: the attachment assembly combines adhesive bonding with sealing functions, while the spacer assembly combines spacing functionality with attachment surfaces for the glazing layer. This merging reduces the number of separate components and steps required during installation, making the manufacturing and installation process easier.

AI summary
A window glazing assembly that can convert an existing or already-installed window, or be used to assemble new construction windows as a multi-pane or multi-glazed window unit, is provided herein. In particular, the glazing assembly includes an attachment assembly (e.g., peel-and-stick double-sided adhesive tape) and one or more glazing layers. Some embodiments further include a spacer assembly comprising a plurality of spacer bars that may be individually installed, e.g., one by one, around the perimeter of the window such as, to the window sash, window frame, or glass window pane, itself. The glazing layer(s) can then be secured or adhered to the spacer assembly, for example, around the perimeter thereof. Some embodiments may include additional or intermediate glazing layers, providing additional insulating airspaces and enhanced performance.
