Solution Overview
Problem
Existing filling elements for doors, windows, and facades face challenges in mitigating deflection due to temperature stresses, which are not fully addressed by previous solutions that incorporate elastic compensation layers.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single elastic compensation layer is used to connect cover layers to the core, then mobility of the outer cover layer is improved, but dimensional stability against temperature stresses is insufficient
Solution Approach 1:
The core is divided into multiple separate insulating layers (first insulating layer and second insulating layer) instead of using a single solid core. These layers are spaced apart and connected by elastic compensation elements, creating a segmented structure that allows differential movement while maintaining overall stability.
Solution Approach 2:
Elastic compensation elements are introduced as intermediary components between the insulating layers and cover layers. These elements act as mediators that absorb thermal expansion forces and allow relative movement, resolving the conflict between mobility and stability.
2Device complexity
If the core is made as a single solid piece, then structural simplicity is maintained, but temperature stresses cause deflection and bending
Solution Approach 1:
The solid core is segmented into multiple separate insulating layers with gaps between them. This segmentation allows each layer to expand and contract independently in response to temperature changes, preventing the bending and deflection that occurs in solid cores while not significantly increasing structural complexity.
Solution Approach 2:
The insulating layers are designed with flexible connections through elastic compensation elements, creating a structure that can flex and adapt to thermal expansion. This flexible design allows the core to accommodate temperature stresses without maintaining rigid structural simplicity.
3Ease of operation
If elastic compensation layers are added to improve mobility, then cover layer movement is enhanced, but the forces from temperature differences are not fully reduced
Solution Approach 1:
By segmenting the core into multiple insulating layers spaced apart from each other, the thermal mass and thermal gradients are reduced. This segmentation allows heat to pass through more easily and reduces the temperature differential across the core, thereby reducing the thermal expansion forces while maintaining the mobility benefits of elastic compensation elements.
Solution Approach 2:
The compensation system is extended from a single-layer approach to a multi-layer spatial arrangement. The elastic compensation elements are distributed across multiple layers and positions (including corner regions), creating a three-dimensional compensation network that more effectively counteracts thermal forces from all directions while maintaining cover layer mobility.
