Screen Housing Truss for Wind Load Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing housing structures for screen devices in door or window openings are insufficiently adapted to absorb loads transferred between the frame and the wall, and previous solutions, such as coupling elements between the top and bottom profiles, are difficult to attach and do not adequately absorb bending forces in a horizontal plane.
Innovation Solution
A housing structure with a detachable upright wall and rotatable coupling elements that include first and second fastening flanges, allowing for the transfer of loads between the frame and the wall while maintaining ventilation, and a truss configuration that is rigidly connected to the wall element to absorb flexure and bending forces effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If coupling elements are fitted between the top profile and the bottom profile to absorb loads, then load transfer capability is improved, but the complexity of attachment increases
Solution Approach 1:
The coupling element is divided into two functional parts: a first coupling part integrated into the housing structure and a second coupling part integrated into the frame. This segmentation allows each part to be optimally designed for its specific function while simplifying the overall attachment process through modular integration.
Solution Approach 2:
The coupling elements are merged with the housing structure and frame through integration, creating a unified load-transfer system. The first coupling part is combined with the housing structure's top and bottom profiles, while the second coupling part is combined with the frame, eliminating separate attachment components and reducing complexity.
2Strength
If the housing structure is made rigid to absorb bending forces, then structural strength is improved, but adaptability for different installation conditions deteriorates
Solution Approach 1:
The housing structure is segmented into a rigid load-bearing framework (profiles and coupling elements) and a detachable functional component (upright wall). This allows the structural framework to maintain rigidity for bending force resistance while the detachable upright wall provides installation adaptability through easy removal and reconfiguration.
Solution Approach 2:
The upright wall is designed with detachable connections to the top and bottom profiles, transforming it from a fixed to a dynamic component. This allows the housing structure to adapt to different installation conditions by enabling easy assembly, disassembly, and reconfiguration, while the integrated coupling elements maintain structural rigidity for load bearing.

AI summary
The present invention relates to a strong housing structure for a screen device (1) for fitting in a door or window opening in a wall, comprising a bottom profile (2) and a top profile (3) having a space in between for a screen roller (4) and next thereto and at least partly in a zone above the frame (25), within the width of the frame (25), an upright wall (6 ,7) which is rigidly and detachably connected to these profiles (2, 3), and is provided with one or more openings (38) and is substantially configured as a truss (7) next to these openings (38) for transferring loads between the frame (25) and the wall.
