Modular Accessory Box for Roller Shutters with Adjustable Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roller shutter installations with accessory boxes are not easily mountable or removable regardless of the configuration, particularly when installed in lintels or half-lintels, as they are not adaptable to different mounting setups and can obstruct protective canvases during movement.
Innovation Solution
A modular accessory box designed to fit directly onto the brackets supporting the roller shutter shaft, with adjustable length and alignment to accommodate various configurations, featuring a hollow cylindrical central portion and cheek components that can be fixed to the brackets or guidance flasks, allowing for easy assembly and disassembly, and incorporating features like alignment organs and guidance tulips to manage the protective canvas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the accessory box is fixed to the roller shutter box using existing methods (clipped onto internal walls or fixed to the roller shutter box), then the box can be securely mounted, but it cannot be easily disassembled or adapted to different configurations (lintel mounting, half-lintel mounting, etc.)
Solution Approach 1:
The accessory box is divided into a body portion and two separate fixing portions that can be independently positioned and attached to different support elements (brackets or guide flanges), allowing the box to be adapted to various mounting configurations while maintaining secure fixation
Solution Approach 2:
The fixing portions are designed to be compatible with multiple types of support elements (both brackets and guide flanges), enabling the same accessory box design to be used across different roller shutter configurations including lintel mounting, half-lintel mounting, and box mounting
2Reliability
If the accessory box is designed with fixed dimensions to fit specific configurations, then it can be securely mounted in that configuration, but it cannot be easily removed or installed in different configurations
Solution Approach 1:
The accessory box transitions from a static, fixed-dimension design to a dynamic configuration where the body portion can be positioned at different locations relative to the fixing portions, allowing easy adaptation to different mounting scenarios while maintaining secure fixation in each configuration
3Device complexity
If the box length is fixed, then the structure is simple, but the protective fabric may be blocked during movement in certain configurations
Solution Approach 1:
The box length parameter is made variable through the adjustable positioning of the body portion relative to the fixing portions, allowing the effective length to be optimized for different mounting configurations to prevent blocking of the protective fabric while maintaining overall structural simplicity

AI summary
This housing (50) is designed for a roller shutter installation (10) and is configured to house an accessory, in particular a protective screen. The housing (50) has an elongated shape along a main axis (A50) and comprises two opposite ends, each configured to be fixed respectively to a support element chosen from among a bracket (20) supporting a winding tube (26) of a protective screen of the roller shutter installation (10), or a guide flange of the protective screen.
