Roller Shutter Box Mounting Mechanism with External Lever Clamp
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roller shutter boxes are difficult to install and maintain, as they require removing insulation and disrupting the sealing between the window frame and the outer wall to access and remove anchors, making maintenance or replacement of the roller shutter impossible without compromising insulation and sealing.
Innovation Solution
A mounting mechanism with a clamp and lever system that allows the roller shutter box to be securely fastened to a mounting frame without opening the box, using a clamp that engages with an undercut section and is accessible from outside, enabling easy installation and maintenance while maintaining insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional anchors are used in roller shutter boxes, then the box can be securely fastened to the window frame, but the anchors block access to the roller shutter for maintenance or replacement
Solution Approach 1:
The mounting mechanism is divided into separate components: a clamp that engages with the box and an actuating member that operates independently. This segmentation allows the fastening function to be separated from the access path, enabling roller shutter maintenance without removing anchors.
Solution Approach 2:
The clamp acts as an intermediary element between the box and the mounting frame. It provides the secure fastening function while being operable through the side opening, thus mediating between the need for secure attachment and the need for maintenance access.
2Ease of manufacture
If the roller shutter box is opened to access anchors for installation, then the anchors can be fastened to the window frame, but the insulation and sealing are disrupted
Solution Approach 1:
The box is pre-configured with a side opening that provides access to the mounting mechanism components. This preliminary action allows anchor installation to be performed without opening the box walls, thereby preserving insulation and sealing integrity.
Solution Approach 2:
The actuating member is extracted or extended through the side opening of the box, allowing operation of the clamp from the exterior. This extraction enables anchor installation without compromising the box's insulation and sealing properties.
3Stability of the object's composition
If multiple anchors are installed in the roller shutter box, then the box stability is improved, but the complexity of the mounting mechanism increases
Solution Approach 1:
The clamp and actuating member mechanism serves multiple functions: it fastens the box to the mounting frame, provides stable anchoring, and enables easy operation through the side opening. This multi-functionality reduces the need for additional complex components while maintaining box stability.
