Building Closure Device with Integrated Motor and Obstacle Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closing and concealment devices for buildings, such as garage doors and rolling shutters, are bulky and aesthetically unpleasing due to the need for large motorized systems and winding tubes, and lack effective obstacle detection and stopping mechanisms.
Innovation Solution
A compact closure or concealment device with motorized drive means integrated within a final portion, featuring a detection system for obstacle detection and control mechanisms to stop the device upon contact, allowing for reduced size and improved aesthetics, and incorporating articulation means for stacking slats inside a roller shutter box.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If motorized drive means are located externally (on ceiling or walls), then the device can be operated effectively, but the installation requires considerable space and additional structures that increase complexity and cost
Solution Approach 1:
The patent combines the motorized drive means with the final section of the closing device by providing a cavity in the final section that receives the motorized drive means. This integration eliminates the need for separate external mounting structures on ceilings or walls, reducing installation complexity while maintaining operational effectiveness.
2Ease of operation
If winding tube and slats are used for roller shutter, then the curtain can be wound and unwound effectively, but the assembly requires a large roller shutter box that protrudes from the building and detracts from aesthetics
Solution Approach 1:
The patent merges the winding tube assembly with the final section by providing a cavity in the final section that receives the winding tube. This integration allows the roller shutter box to be compact and flush with the building facade, eliminating protrusions that would detract from aesthetic appearance while maintaining the curtain winding function.
3Reliability
If detection system with blocking means is added to detect obstacles, then safety is improved, but the device complexity increases
Solution Approach 1:
The patent combines the detection system with the final section by housing the blocking means and actuating means within the cavity of the final section. This integration provides obstacle detection capability for safety while minimizing additional complexity through space-efficient design.
