Stepped Wall Insulation for Window Frame Heat Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window frame insulation methods fail to effectively prevent heat loss around window frames due to gaps in insulation coverage and increased manufacturing costs and construction time, particularly when installing heat transfer cutoff members between window frames and concrete walls.
Innovation Solution
A method involving forming a stepped portion in the wall to accommodate insulation materials, where the insulation is installed on the inner side and sheathing material on the outer side, ensuring comprehensive insulation coverage and reducing heat transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a heat transfer cutoff member is installed between the window frame and concrete wall, then heat loss is reduced, but manufacturing costs increase and construction time is extended
Solution Approach 1:
The patent removes the heat transfer cutoff member from the construction system and replaces it with a stepped portion formed directly in the concrete wall. This extraction eliminates the need for separate insulation components while maintaining the heat loss reduction function through the stepped geometry that allows insulation material to extend closer to the window frame.
Solution Approach 2:
The patent combines the wall structure and insulation accommodation into a single integrated stepped portion. The stepped portion is formed as part of the concrete wall casting process, merging the structural wall function with the insulation support function, thereby eliminating separate insulation components and reducing construction complexity.
2Loss of energy
If a heat transfer cutoff member is installed between the window frame and wall surface, then insulation performance is improved, but manufacturing costs increase
Solution Approach 1:
The patent extracts the heat transfer cutoff member from the system and replaces it with a geometric feature (stepped portion) formed during concrete wall construction. This eliminates the need to manufacture and install separate insulation components, reducing manufacturing costs while maintaining insulation performance.
Solution Approach 2:
The stepped portion is formed during the concrete wall casting process before the insulation material is installed. This preliminary action integrates the insulation accommodation structure into the wall construction itself, eliminating subsequent insulation component manufacturing and installation steps.
3Loss of energy
If exterior insulation material is installed on the outer side of the wall, then heat loss is prevented, but the insulation material cannot cover the edge of the opening where the window frame is installed
Solution Approach 1:
The patent creates a stepped portion that extends in the depth dimension (from the wall outer surface toward the interior). This dimensional change allows the insulation material to be positioned closer to the window frame by utilizing the stepped geometry, thereby increasing the insulation coverage area around the window opening without compromising the exterior insulation layer.
