Window Insulation Profile Assembly with Gap Tolerance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window and door profile arrangements require precise dimensional accuracy of insulating bodies to ensure proper closure and thermal insulation, which can be challenging to maintain and results in suboptimal performance if deviations occur.
Innovation Solution
A profile arrangement where the first and second insulating bodies have a defined gap between them, greater than zero but not exceeding 2 mm, allowing for effective thermal insulation without the need for tight tolerances, using poorly conducting materials like polyamide for the insulating strips and allowing for flexible configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If insulating bodies are arranged between the frame and casement to provide thermal insulation, then thermal insulation performance is improved, but dimensional accuracy and assembly precision must be very high to ensure proper closure
Solution Approach 1:
The patent introduces seal carriers with hose seals as intermediary elements between the insulating bodies and the closure system. These seal carriers compensate for dimensional deviations of the insulating bodies, allowing the insulating bodies to have lower manufacturing precision while still achieving proper closure and thermal insulation performance.
Solution Approach 2:
The patent changes the dimensional parameters of the closure system by introducing adjustable seal carriers that can accommodate variations in insulating body dimensions. This allows the system to function properly even when insulating bodies have deviations from nominal dimensions, effectively decoupling thermal insulation performance from strict dimensional accuracy requirements.
2Temperature
If insulating bodies are attached to opposing insulating bars, then thermal insulation is achieved, but the arrangement requires precise positioning and assembly
Solution Approach 1:
The seal carriers act as mediators between the insulating bodies and the frame/casement structure. They provide a tolerance-absorbing interface that simplifies assembly by compensating for positioning deviations, making the assembly process easier while maintaining effective thermal insulation.
Solution Approach 2:
The patent segments the closure system into modular components including insulating bodies, seal carriers, and hose seals. This segmentation allows each component to be manufactured and assembled independently with relaxed tolerances, while the overall system maintains its thermal insulation function through the coordinated arrangement of these segments.
3Ease of operation
If a gap is provided between sealing elements, then the blind frame and casement can close properly, but thermal insulation performance deteriorates due to air flow
Solution Approach 1:
The patent uses flexible hose seals mounted on seal carriers to bridge the gap between the blind frame and casement when closed. These flexible sealing elements can deform to fill the gap effectively, preventing air flow and maintaining thermal insulation performance while allowing the frame and casement to close properly.
Solution Approach 2:
The seal carriers with hose seals provide a dynamic sealing solution that adapts to the closing movement. The hose seals can deform and adjust their position during closure to maintain effective sealing, thereby preventing air flow and preserving thermal insulation while enabling proper closure functionality.
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
This solution provides enhanced thermal insulation by minimizing heat conduction through the insulating bodies while avoiding the need for precise dimensional accuracy, ensuring effective sealing and air flow prevention between inner and outer spaces.
Implementation Method 1
a first insulating body (21) and a second insulating body (22) in the area between the frame B and the casement F... which are preferably located in the planes of the insulating bars (11, 13), insulated. The shape of the insulating bodies (21, 22) can, as shown in the drawing, be semicircular in cross section, but can also be shaped differently. The thermal conductivity of the insulating body (21, 22) should be as small as possible
Implementation Method 2
a defined distance S is provided between the insulating bodies (21, 22), which is greater than zero but does not exceed a value of 2 mm. Despite the existing but small distance, a flow of air from an inner half-space H1 into an outer half-space H2 can be avoided.

AI summary
The profile arrangement has four profiles (1,2,3,4) which are connected with insulation webs (11,12,13,14) in a respective manner. An insulating body (21) is attached at the arrangement of the former and latter profiles and the insulation web. Another insulating body (22) is attached at the arrangement of the third and fourth profiles and the insulation web. The insulating bodies have a gap (S) between the bodies with closed window or door. An independent claim is included for a door frame and a window frame arrangement with an insulating body.
