Concealed Coupling Device for Manual Emergency Window Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic window and door systems with a single axis of rotation fail to allow manual emergency opening when the automatic drive fails, especially when the sash is in a closed position, and visible coupling mechanisms detract from the aesthetic appearance.
Innovation Solution
A concealed coupling device is designed to be decoupled from outside the frame without damaging it, using a gap between the window and sash frames, and can be actuated wirelessly or manually with a tool, featuring a sliding bolt mechanism for secure and non-destructive emergency opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the coupling device is arranged completely concealed in the closed state, then the visual appearance is improved, but the accessibility for manual uncoupling deteriorates
Solution Approach 1:
A coupling pin serves as an intermediary element that extends through the profile frame to provide external access to the concealed coupling device. The pin can be manually operated from outside the frame to uncouple the drive mechanism, while the coupling device itself remains hidden within the frame structure when closed.
2Ease of operation
If the coupling pin is made massive for easy manual operation, then the ease of operation is improved, but the visual appearance deteriorates
Solution Approach 1:
The coupling mechanism is segmented into multiple components: a massive coupling pin for manual operation, a coupling device with movable component for mechanical engagement, and a profile frame structure. This segmentation allows the pin to be operated easily while remaining visually acceptable when not in use.
3Shape
If the drive is arranged completely covered from outside, then the visual appearance is improved, but the accessibility for repair and replacement deteriorates
Solution Approach 1:
The coupling device is designed to be extractable from the profile frame through the gap between frame and sash frame. This allows the coupling device to be removed and replaced from outside the closed frame structure, providing easy access for repair and replacement while maintaining concealed arrangement during normal operation.

AI summary
The window or door unit has a wing with a window sash (2), where the wing is movable in particular tiltable or pivotable relative to a window frame (1). An automatic drive (3) opens and closes a window, and has a detachable coupling device for coupling the drive with the sash or the window frame. The coupling device is completely arranged in the movable sash, the fixed window frame or between the sash and the window frame. The coupling device is designed in such a manner that it is decoupled from a position outside of the sash or the window frame.
