Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thermal insulation arrangements between the frame and sash of doors or windows require precise dimensional accuracy to prevent improper closure, leading to reduced insulation properties and potential friction, especially when the sash is rotated.
Innovation Solution
A profile arrangement with angled gaps between insulating elements, oriented obliquely to the longitudinal direction of the insulating webs, to minimize heat transfer and prevent contact during rotation, featuring detachable attachment and variable gap designs for enhanced thermal insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the insulating bodies are arranged with a gap of 0-2 mm between them, then manufacturing precision requirements are reduced, but thermal insulation properties deteriorate
Solution Approach 1:
The gap between the insulating bodies is designed to be asymmetric in its distribution pattern, with the gap running diagonally rather than uniformly. This asymmetric arrangement allows the gap to maintain insulation effectiveness while being more tolerant of manufacturing variations, as the thermal path is disrupted in a way that doesn't require precise gap uniformity.
Solution Approach 2:
The gap is oriented diagonally across the insulating bodies rather than parallel to their main surfaces, introducing a dimensional orientation that improves insulation performance. This diagonal arrangement creates a more effective thermal break while allowing for greater manufacturing flexibility compared to a uniform parallel gap arrangement.
2Ease of operation
If the insulating bars are offset between outer and inner half-shells, then assembly ease is improved, but thermal insulation properties deteriorate
Solution Approach 1:
The insulating bodies are segmented into multiple sections along their length, with each section capable of being assembled independently. This segmentation allows the insulating bars to be offset between half-shells during assembly while maintaining continuous insulation coverage through the segmented structure, preventing thermal bridging even with the offsets.
3Reliability
If the gap between insulating bodies is reduced to prevent friction during sash turning, then wear is reduced, but thermal insulation properties deteriorate
Solution Approach 1:
The gap is arranged diagonally rather than uniformly, creating an asymmetric configuration that prevents the insulating bodies from making contact during sash turning operations. This asymmetric diagonal gap ensures that the turning movement does not close the gap completely, preventing friction and wear while maintaining adequate thermal insulation performance.

Function Achieved in This Case
The angled gap design improves thermal insulation by reducing heat transfer through convection and wear, while allowing for easy installation and replacement of insulating bodies, maintaining effective insulation even with sash rotation.
Implementation Method 1
The angled gap between the insulation elements further prevents heat transfer, particularly through convection
Implementation Method 2
a first insulating body which is attached to the at least one insulating bar of the window frame; a second insulating body which is attached to the at least one insulating bar of the window frame, wherein the insulating bodies face each other when the window or door is closed and the first insulating body and the second insulating body have a gap between them
