Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial and residential buildings face significant energy losses and occupant discomfort due to inefficient windows, making full window replacement costly and often uneconomical, and existing weatherization methods fail to effectively address these issues.
Innovation Solution
An insulating panel assembly is introduced that fits within a window jamb, featuring a frame with a compressible seal and barriers to minimize conductive and radiant energy losses, reducing airflow and creating an insulating chamber to enhance energy efficiency and occupant comfort without the need for full window replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If full window replacement is implemented, then energy efficiency and occupant comfort are improved, but installation cost and complexity increase significantly
Solution Approach 1:
The invention divides the window treatment into separate components: an interior insulating glass assembly that can be installed independently within the existing window jamb, without replacing the entire window unit. This segmentation allows the insulating assembly to be added to existing windows, reducing energy loss while avoiding the complexity of full window replacement
Solution Approach 2:
The interior insulating glass assembly is nested within the existing window jamb structure. The frame of the insulating assembly fits inside the jamb, creating a nested configuration that provides insulation without requiring removal of the original window, thereby reducing installation complexity while improving energy efficiency
2Ease of manufacture
If traditional weatherization methods (caulking and weatherstripping) are used, then installation cost is reduced, but energy loss reduction is insufficient
Solution Approach 1:
The interior insulating glass assembly uses a composite structure combining glass panels, insulating frames, and sealing materials. This composite design provides superior insulation performance compared to simple caulking or weatherstripping, while remaining more cost-effective than full window replacement by utilizing affordable insulating materials in a structured assembly
3Object-affected harmful factors
If the frame is sealed to prevent air passage, then air infiltration is reduced, but condensation risk increases due to trapped moisture
Solution Approach 1:
The frame is designed with modified parameters including specific porosity characteristics and ventilation features that allow controlled air exchange. This prevents complete sealing, thereby reducing air infiltration while avoiding moisture trapping that would lead to condensation. The frame's structural parameters are optimized to balance sealing and ventilation needs
Applied Scientific Principles
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 significantly reduces energy consumption and improves occupant comfort by minimizing air infiltration and exfiltration rates, achieving energy savings comparable to high-performance replacement windows while being more cost-effective and aesthetically appealing.
Implementation Method 1
a compressible seal extending outwardly from an external perimeter surface of the frame. In an installed condition, the frame bears the compressible seal against the jamb
Implementation Method 2
The frame is configured to fit within the jamb, and the frame has an external perimeter, an internal perimeter, and at least one frame portion defining at least one cavity extending along its length. The cavity is located between the internal perimeter of the frame and the external perimeter of the frame and is enclosed to prevent the passage of air

AI summary
An airflow reduction system includes an insulating panel assembly for sealing a window within a jamb. The insulating panel assembly has a frame configured to fit within the jamb and a glazing panel in the frame coated with a low-emissivity or solar control coating or film. The frame may include one or more cavities extending along its length. The assembly may also include a blind stop and/or a trim stop installed on either side of the frame within the jamb. A compressible seal around the external perimeter of the frame bears against the jamb to form a first barrier impeding the flow of air, and the blind stop or the trim stop forms a second barrier impeding the flow of air. Also disclosed is a mounting assembly including an insulating panel assembly and at least one bracket and a method of installing the same.
