Pivoting Roller Shutter Bracket for Insulated Box Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly and maintenance of roller shutter systems are complicated due to the difficulty in accessing the roller shutter tube within thermally insulated and airtight roller shutter boxes, which are increasingly common in energy-efficient homes, posing safety risks and requiring degradation of thermal performance or refinishment of the wall.
Innovation Solution
A bracket system comprising a flange and a fitting with a pivot mechanism, allowing the roller shutter tube to be easily assembled and disassembled while ensuring safety, with a tilting angle limited by guide means to prevent mishandling and accidents, and a pre-assembled mounting sub-assembly for time-saving installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the roller shutter box is made airtight and thermally insulated, then energy performance is improved, but access for assembly and maintenance becomes difficult
Solution Approach 1:
The support structure is divided into two separate parts: a fitting fixed to the box and a flange for positioning the tube. These parts can be assembled and disassembled independently through the lower slot without opening the box, enabling maintenance while preserving the box's airtight and insulated structure
Solution Approach 2:
The support assembly (flange and fitting) is extracted as a separate assembly unit that can be installed and removed through the lower slot. This allows the roller shutter tube to be accessed and maintained without compromising the thermal performance of the box
2Volume of moving object
If the roller shutter box is integrated into the wall structure, then space is optimized, but access for maintenance requires degradation of thermal performance or refinishment
Solution Approach 1:
The support components are extracted as removable elements that can be accessed through the lower slot. This enables maintenance of the roller shutter tube without needing to open the box or refinish the wall, preserving both the integrated structure and thermal performance
3Reliability
If the support structure is made stable and secure, then safety is improved, but assembly and disassembly becomes more complex
Solution Approach 1:
The flange is designed to pivot relative to the fitting during assembly, allowing it to be inserted through the lower slot in a tilted position and then rotated into its final position. This dynamic assembly process simplifies installation while maintaining structural stability through the fixed fitting and secured flange
4Ease of operation
If the transverse dimension of the positioning bracket is reduced, then ease of passage through slot is improved, but stability during assembly may be compromised
Solution Approach 1:
The positioning bracket is designed with a compact transverse dimension to pass through the lower slot, and incorporates a pivoting mechanism that allows it to be inserted in a reduced profile and then rotated into its stable operational position, achieving both compactness and stability

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates safe and efficient assembly and disassembly of roller shutter systems without compromising thermal performance, reducing the risk of accidents, and allowing for easy maintenance without opening the roller shutter box.
Implementation Method 1
The flange is pivotally mounted on the fitting along an axis of rotation orthogonal to the first and second plates, and movable in pivoting around the axis of rotation, between a mounting position, in which a tilting angle defined between the first longitudinal axis of the flange and the second longitudinal axis of the fitting has a first value, and a position of use in which the angle of tilt has a second value different from the first value
Implementation Method 2
The guide means comprise an oblong slot, arranged in an arc of a circle centered on the first pin hole

AI summary
A positioning bracket (26) for a roller shutter winding tube (20) within a roller shutter box (14) comprises a flange formed in a first plate and defining a first longitudinal axis, and a fitting formed in a second plate defining a second longitudinal axis. The flange is pivotally mounted on the fitting along an axis of rotation orthogonal to the first and second plates, and is movable by pivoting about the axis of rotation between a mounting position, in which a defined tilting angle between the first longitudinal axis of the flange and the second longitudinal axis of the fitting has a first value, and an operating position in which the tilting angle has a second value different from the first value.
