Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roller shutter boxes are not easily adjustable to match the width of the roller shutter curtain, leading to misalignment due to assembly errors and a bulky design.
Innovation Solution
A variably adjustable roller shutter box composed of profile parts forming a tube-like device with a prismatic front cover featuring grooves and tongues for secure alignment and connection, allowing for individual width adjustment and a compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If roller shutter boxes are constructed with traditional end caps and profiles, then assembly is straightforward, but adjustment to match different curtain widths is difficult and misalignment occurs
Solution Approach 1:
The roller shutter box is divided into modular profile sections that can be selectively assembled. Each profile section has standardized connection interfaces (grooves and tongues) allowing different combinations to achieve various widths. This segmentation enables easy adaptation to different curtain widths without requiring complex adjustment mechanisms.
Solution Approach 2:
The connection system uses detachable grooves and tongues that allow dynamic reconfiguration of the roller shutter box width. The grooves in one profile section engage with tongues in adjacent sections, creating a flexible assembly that can be adjusted by adding or removing profile sections to match different curtain widths.
2Manufacturing precision
If roller shutter boxes use traditional connection methods between end caps and profiles, then manufacturing is simple, but alignment precision and secure connection are insufficient
Solution Approach 1:
The connection interface uses asymmetric grooves and tongues where the groove geometry and tongue shape are specifically designed to mate precisely. The asymmetric design ensures proper alignment during assembly while maintaining manufacturing simplicity through standardized profile extrusions.
Solution Approach 2:
The grooves and tongues act as intermediary connection elements between profile sections and end caps. These intermediaries provide precise alignment surfaces that guide components into correct positions during assembly, ensuring high alignment precision without complex manufacturing processes.
3Adaptability or versatility
If roller shutter boxes are designed with fixed width, then manufacturing is easier, but adaptability to different window sizes is limited
Solution Approach 1:
The roller shutter box is constructed from multiple standardized profile sections that can be assembled in different quantities and configurations. This segmentation allows the same basic profile design to be used across different window sizes, maintaining manufacturing efficiency while achieving adaptability through modular assembly.
Solution Approach 2:
The profile sections are designed with universal connection interfaces (grooves and tongues) that can accommodate various assembly configurations. The same profile design serves multiple functions and can be used for different width requirements, eliminating the need for multiple specialized components and maintaining high manufacturing productivity.

AI summary
A roller shutter box (1) with several profile parts (2, 3, 4, 5) which are connected to form a tubular device (6) and at least one end cap (7) which closes off the tubular device (6) laterally, is characterized in that the end cap (7) is essentially prismatic and has a base surface (8) and a lateral surface (9), while the lateral surface (9) of the end cap (7) has essentially the same contour as the interior of the tubular device (6). The tubular device (6) has at least two grooves (10) and/or tongues (11) extending along its inner surface, while the end cap (7) has corresponding grooves (10) and/or tongues (11) on its lateral surface (9).
