Window Frame Nesting for Thermal Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing windows with traditional configurations have limited thermal and acoustic insulation performance due to exposed peripheral surfaces of the opening and sleeping chassis, which are prone to thermal exchanges and air infiltrations.
Innovation Solution
A window design featuring an opening frame, a sleeping frame, and cooperating glazing that forms a multilayer structure when closed, with the frames arranged behind the glazing to minimize exposed surfaces and enhance insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional window configuration with exposed peripheral surfaces is used, then manufacturing and assembly are simple, but thermal and acoustic insulation performance is limited
Solution Approach 1:
The opening frame is nested within the fixed frame when the window is closed, creating a multi-layer structure where the opening frame is positioned behind the glazing. This nesting arrangement reduces the exposed peripheral surfaces to minimal areas while maintaining simple manufacturing processes for each individual frame component.
Solution Approach 2:
The invention transitions from a traditional single-plane frame configuration to a multi-dimensional arrangement where frames are positioned at different depths relative to the glazing. The opening frame is placed behind the glazing plane while the fixed frame remains at the front, creating a depth dimension that reduces thermal bridges and exposed surfaces.
2Loss of energy
If profile thickness is increased to improve insulation, then thermal and acoustic performance improves, but manufacturing costs and installation complexity increase
Solution Approach 1:
Instead of increasing the thickness of individual profiles, the invention uses a nested arrangement where the opening frame is positioned within the depth of the fixed frame structure. This creates effective insulation without requiring excessively thick individual profiles, maintaining manufacturing simplicity and cost-effectiveness.
3Loss of energy
If opening frame is concealed within fixed frame, then exposed sensitive areas are reduced, but manufacturing complexity and production cost increase
Solution Approach 1:
The opening frame is concealed within the fixed frame by positioning it behind the glazing plane, creating a nested appearance where only minimal portions of the opening frame are exposed. This is achieved through straightforward assembly procedures rather than complex shaping operations, maintaining ease of manufacture while reducing thermal bridges.

AI summary
The invention concerns a window (100) comprising an opening frame (110), a fixed frame (120) and a glazing (130) interacting in a fixed manner with said opening frame (110), as well as means for moving the opening frame (110) with respect to the fixed frame (120) during opening/closing at the window (100). In addition, the opening frame (110) and the movement means are arranged between the glazing (130) and the fixed frame (120), so that the window (100) forms, when closed, a multilayer structure having: a height and a width substantially identical to the corresponding dimensions of the glazing (130), - a thickness at least equal to the sum of the respective thicknesses of the glazing (130), the opening frame (110) and the stationary frame (120).
