Roller Shutter Box with Embedded Lintel Anchoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for integrating roller shutter boxes into building walls above openings face challenges such as visibility, difficulty in fixing, and inadequate structural support, particularly due to the thinness of the roller shutter box walls which cannot withstand wind pressures effectively.
Innovation Solution
A roller shutter tunnel box with an inverted U-shaped section is designed to include a fixing reinforcement within its reservation, featuring an anchoring lug that is embedded in the concrete lintel during construction, providing a solid connection between the carpentry and masonry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the roller shutter box walls are made thin to facilitate handling and integration, then ease of manufacture and integration is improved, but structural strength and ability to withstand wind pressures deteriorates
Solution Approach 1:
The fixing reinforcement is segmented into multiple components: an anchoring lug for embedding in the lintel, a vertical bar portion within the reservation, and horizontal fixing arms extending toward the carpentry. This segmentation allows each part to perform its specific function optimally while keeping the overall box wall thin.
Solution Approach 2:
The fixing reinforcement utilizes the third dimension (depth/thickness of the box wall) by embedding the anchoring lug in the lintel above and extending the vertical bar through the reservation depth, thereby achieving strong fixation without increasing the external dimensions of the box.
2Strength
If fixing reinforcement elements are added to ensure solid fixation, then structural strength is improved, but device complexity and manufacturing difficulty increases
Solution Approach 1:
The fixing reinforcement integrates multiple functions into a single element: anchoring to the lintel via the lug, spanning the box wall thickness through the vertical bar, and providing fixation points for carpentry through horizontal arms. This merging reduces the number of separate components needed.
Solution Approach 2:
The fixing reinforcement serves multiple purposes simultaneously: it anchors the box to the building structure, provides structural support across the thin wall, and creates fixation points for the carpentry. This multi-functionality reduces the need for separate anchoring and fixing systems.
3Adaptability or versatility
If the roller shutter box extends towards the interior of the dwelling to accommodate the winding mechanism, then functionality is improved, but the box becomes visible and projects from the internal side deteriorating aesthetic appearance
Solution Approach 1:
The winding mechanism and roller shutter components are nested within the box structure, utilizing the space efficiently. The box is integrated into the wall thickness and the reservation, allowing the mechanism to be housed without excessive projection into the dwelling interior.
4Loss of energy
If the box is made of lightweight insulating materials to improve insulation performance, then thermal insulation is improved, but the material cannot constitute a support for solid fixing of the carpentry deteriorates
Solution Approach 1:
The fixing reinforcement acts as an intermediary element between the lightweight insulating box wall and the carpentry. It provides the necessary mechanical strength and fixation capability while the box wall itself maintains its insulating function with thin, lightweight materials.

AI summary
The box (1) has re-entrant (15) provided in an external side (12) of the box at a front wall (5) and/or rear wall (7) in thickness (14) of the front or rear wall and approximately and vertically extended. A fixing reinforcement (16) fixes joinery on masonry. The reinforcement is housed in the re-entrant. The re-entrant extends from a lower edge of the front or rear wall until an upper wall (9). The reinforcement comprises an anchoring tab (18) extended above the upper wall for being embedded in a lintel.
