Roller Shutter Box End Profile for Wall Plaster Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing roller shutter box assembly and adjustment process in wall recesses is labor-intensive, requiring significant material and time to achieve a flush finish with the wall plaster, and lacks a secure and precise connection mechanism.
Innovation Solution
A roller shutter box design featuring a horizontal plate-shaped end profile with a locking profile attached to a parallel aluminum profile in the inner wall, allowing flexible adaptation to wall thickness and a clean plaster connection, eliminating the need for a corner protection rail and ensuring a secure hold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional roller shutter box assembly method is used, then the box can be installed in the wall recess, but the assembly and adjustment work is labor-intensive and time-consuming
Solution Approach 1:
The end profile is pre-assembled with the roller shutter box during manufacturing, including the locking profile and connection elements. This preliminary preparation eliminates the need for complex on-site assembly operations, allowing installers to simply attach the pre-assembled unit to the wall recess, thereby reducing labor intensity and installation time while maintaining ease of operation
Solution Approach 2:
The roller shutter box assembly is divided into modular components: the base body, the end profile with locking mechanism, and the plaster connection elements. This segmentation allows each component to be independently manufactured and prepared, then quickly assembled on-site through simple connection operations, significantly improving assembly productivity without increasing operational complexity
2Adaptability or versatility
If the roller shutter box is designed to fit various wall thicknesses, then flexibility is improved, but the device complexity increases
Solution Approach 1:
The end profile is designed as a detachable component that can be adjusted in length and position along the inner wall. The locking profile mechanism allows the end profile to be positioned at different depths corresponding to different wall thicknesses, providing adaptability without requiring multiple fixed-depth box designs, thus avoiding increased device complexity
Solution Approach 2:
The design allows modification of the end profile length parameter to match different wall thicknesses. By changing this single parameter rather than redesigning the entire box structure, the system achieves versatility across various wall thicknesses while maintaining simple, standardized box geometry, thereby avoiding complexity increases
3Reliability
If a secure connection mechanism is implemented, then the hold of the end profile is improved, but the device complexity increases
Solution Approach 1:
The locking profile acts as an intermediary element between the end profile and the roller shutter box body. This simple protruding structure provides secure mechanical interlocking through a snap-in or friction-fit connection, ensuring reliable holding without requiring complex fasteners, screws, or multi-component connection mechanisms, thus maintaining device simplicity while achieving high connection security

AI summary
The invention relates to a roller shutter box with a base body in profile form made of stable plastic foam with a U-shaped, downwardly open cross-section, wherein the downwardly open interior of the base body, which receives the roller shutter winding, is bounded on the side facing the building by a downwardly projecting inner wall, wherein a horizontal, plate-shaped end profile is attached to the underside of the inner wall, the width of which is adapted to the width of the inner wall and the plaster, and wherein a plaster connection profile sits on the end of the end profile facing the building, parallel to the longitudinal extent of the base body.
