Adapter Strip Leverage Mechanism for Roller Shutter Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roller shutter box systems face challenges in maintaining stability and preventing twisting or displacement, especially under load conditions, due to inadequate connection mechanisms between the roller shutter box and the frame.
Innovation Solution
A symmetric adapter strip design that allows the roller shutter box to be plug-connected to the frame using a static part with an insertion section directed towards the room, providing a favorable leverage effect and additional stabilization through a temporary pivot axis, and featuring a stop formation to prevent slipping or removal of the insertion section.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a structural component is used to increase stability, then connection stability is improved, but device complexity increases
Solution Approach 1:
The adapter strip combines multiple functions into a single component: it provides structural support, enables plug-in connection of the roller shutter box to the frame, and incorporates a rear grip for securing the structural component. This merging reduces the number of separate parts needed while maintaining connection stability.
Solution Approach 2:
The adapter strip serves multiple purposes: it acts as a structural support element, a connection interface for the roller shutter box base part, and a mounting structure for the structural component. This multi-functionality improves stability without proportionally increasing device complexity.
2Ease of operation
If the adapter strip is designed symmetrically, then ease of installation is improved, but manufacturing precision requirements increase
Solution Approach 1:
While the adapter strip has overall symmetric characteristics for ease of installation in two positions, it incorporates asymmetric features such as the stop formation positioned at a specific distance from the rear grip, and the insertion section with specific geometric constraints. These controlled asymmetric elements provide precise positioning while maintaining installation flexibility.
3Reliability
If the insertion section is secured with a stop formation, then reliability is improved, but device complexity increases
Solution Approach 1:
The stop formation is integrated directly into the adapter strip as a single continuous piece, combining the structural support function with the stopping function. This eliminates the need for separate stopping mechanisms while improving reliability by preventing dislodging of the structural component.
4Stability of the object's composition
If multiple structural components are arranged alternately, then frame stability is improved, but device complexity increases
Solution Approach 1:
The connection system is divided into modular segments: the adapter strip with rear grip, the structural component with insertion section, and the roller shutter box base part. This segmentation allows for alternating arrangement of components along the frame length, improving frame stability while keeping each individual component relatively simple.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances the stability of the roller shutter box system by maintaining the insertion rear grip under load conditions, preventing twisting of the frame, and ensuring secure attachment through a combination of leverage and pivot mechanisms, thus providing effective load distribution and prevention of transverse displacement.
Implementation Method 1
a favorable leverage effect occurs in such a case, preventing the insertion of the static component and adapter strip from disengaging
Implementation Method 2
the insertion section of the static component can be pivoted into the adapter strip by pivoting it about a pivot axis extending longitudinally along the adapter strip

AI summary
The invention relates to a roller shutter box (1) mounted on a frame (2), namely a window or door frame, in a building with a building wall (32), with a room side (R) and an outside side (A), wherein an adapter strip (9) is arranged between a bottom part (6) of the roller shutter box (1) and the top of the frame (2) and the frame (2) is connected to the building wall (32) by means of a structural part (26) passing through the roller shutter box (1), wherein the structural part (26) further has an insertion section (34) for plugging into the adapter strip (9) by means of a (first) rear grip (12) formed on the adapter strip (9).The invention also relates to an adapter strip (9) for connecting a frame (2), namely a window or door frame, in a building with a room side (R) and an outside side (A), wherein the adapter strip (9) has rear grips (12, 13) facing each other in a cross-section (2) with respect to its openings (14). To advantageously improve both a roller shutter box and an adapter strip, it is proposed with regard to the roller shutter box (1) that the insertion section (45) is oriented towards the room side and the rear grip (12) is open towards the outside side (A). An advantageous adapter strip is characterized by a stop projection (20) formed between the rear grips (12, 13).
