Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In modern buildings with multi-layer walls, the installation of doors and windows is challenging due to varying layer thicknesses and material properties, leading to suboptimal heat insulation and structural support, as traditional methods either compromise insulation or lack continuous support.
Innovation Solution
A structural element with horizontal and vertical longitudinal walls connected by shaped ribs, filled with insulating foam, providing a continuous oversailing reveal that supports the window or door while maintaining insulation, using a framework that carries the weight and an insulating layer for rigidity and thermal efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional angle supports are used to support windows punctually, then the window weight is adequately carried, but the structural element does not provide continuous tightness of the window wall fixing and prevents homogeneous continuous insulation
Solution Approach 1:
The patent merges the support function and insulation function into a single integrated structural element. The angle profile includes both the mechanical support structure and insulating material combined in one component, eliminating the need for separate angle supports and insulation layers. This integration ensures continuous insulation around the window while providing adequate structural support.
Solution Approach 2:
The structural element uses composite construction combining a rigid framework (metal or plastic profile) with insulating material (foam or other thermal insulation). This composite structure provides both the mechanical strength needed to support the window and the thermal insulation properties required for continuous insulation, resolving the contradiction between strength and insulation reliability.
2Reliability
If foam materials are used to create continuous insulation plane around the window, then the oversailing reveal continuity is achieved, but the production requires expanding to lower density and then compressing to higher density which is adverse in terms of technology
Solution Approach 1:
The patent specifies using foam material with density in the range of 20-40 kg/m³, which is a parameter optimization that balances insulation performance with manufacturing feasibility. This density range provides sufficient insulation properties while avoiding the complex two-stage expansion-compression process, simplifying production while maintaining continuous insulation reliability.
3Ease of operation
If the window installation position is aligned with the masonry layer, then the installation is simplified in dual- or multi-layer walls, but the installation position cannot be chosen in terms of minimum heat loss
Solution Approach 1:
The patent introduces an intermediary oversailing reveal structure that extends beyond the masonry layer. This reveal acts as a mediator that allows the window to be positioned optimally for thermal performance while the reveal itself provides the structural connection to the masonry. The insulating material within the reveal further reduces heat loss, decoupling the installation simplicity from heat loss minimization.
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 ensures proper support and insulation for windows and doors, maintaining structural integrity and thermal performance without hindering insulating works, using composite materials that balance strength and thermal conductivity.
Implementation Method 1
The spaces between the shaped ribs and between the inlet side wall and the shaped rib and the side wall and the shaped rib are filled with insulating foam
Implementation Method 2
The advantage of this solution is that there is continuity of the oversailing reveal which means that such a profile, unlike in the angle supports punctually underpin the window, constitutes the extension of insulation
