Roller Shutter Box Closure Device With Flexible Sealing Stoppers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closure devices for winding mechanism boxes in rolling shutters face sealing issues due to inadequate opening configurations and lack of effective sealing mechanisms, leading to potential fluid penetration and installation complexities.
Innovation Solution
A closure device with side walls featuring at least two openings, where one opening is obstructed by a flexible stopper to ensure sealed closure, allowing for adjustable passage of tools and control members, and optionally including internal openings for additional sealing, using flexible plastic materials to maintain aesthetic and functional integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple openings are pre-drilled in side walls to cover most installation configurations, then adaptability is improved, but sealing performance deteriorates due to unused openings creating leakage paths
Solution Approach 1:
Multiple openings are pre-drilled in the side walls during manufacturing to accommodate different installation configurations. The stoppers are pre-installed in these openings to maintain sealing. During installation, the appropriate stopper is removed based on the specific configuration needed, ensuring both adaptability and sealing performance are maintained.
Solution Approach 2:
Each opening is equipped with an individual removable stopper that can be selectively removed or retained based on the specific installation requirements. This allows local modification of the sealing property at each opening location while maintaining sealing at other openings, resolving the contradiction between adaptability and sealing performance.
2Reliability
If openings are not pre-drilled and are instead drilled during installation, then sealing performance is improved, but device complexity increases due to installation complications
Solution Approach 1:
The openings are pre-drilled at the factory with precise positioning and appropriate sealing provisions. This preliminary action eliminates the need for on-site drilling operations, reducing installation complexity while maintaining sealing integrity through the pre-installed stoppers that can be selectively removed.
3Device complexity
If a single opening is pre-drilled, then device complexity is reduced, but adaptability deteriorates as the opening may not be located in the right place for all installations
Solution Approach 1:
Multiple openings are provided in the side walls, each capable of serving as the operational opening for different installation configurations. This multi-functional design allows the closure device to adapt to various installation scenarios while maintaining a simple overall structure, resolving the contradiction between simplicity and adaptability.
4Shape
If cleanliness covers are used to conceal openings, then aesthetic appearance is improved, but sealing performance deteriorates as covers do not prevent fluid penetration
Solution Approach 1:
The stoppers are made of flexible material that can be compressed or deformed to create a tight seal when installed in the openings. This material property change enables the stoppers to provide both aesthetic coverage (like cleanliness covers) and effective sealing (preventing fluid penetration), resolving the contradiction between appearance and sealing performance.
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 provides excellent sealing performance, reducing fluid penetration and simplifying installation by ensuring tight closure of openings, while allowing for adjustable access as needed, thus enhancing the overall sealing and aesthetic closure of the box.
Implementation Method 1
at least one of these two openings being obstructed by a stopper capable of ensuring the sealed closure of this obstructed opening

AI summary
The device has a flange (2) for closing a box in one of ends of the box and comprising external vertical side walls (21, 23) and external horizontal side walls (22, 24) oriented perpendicular to a main closing wall (20). External openings (210, 211, 220, 221) are formed on one of the vertical side walls and one of the horizontal side walls, respectively. Dismountable and repositionable caps (3-5) block three of the external openings so as to assure sealed closing of the external openings, where the caps are made of flexible polyethylene.
