Window Tilting Drive Coupling for Manual Rotation and Automatic Tilt
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tilt drive devices for windows and doors lack flexibility in operation, requiring separate mechanisms for manual and automatic tilting, and often fail to maintain a secure coupling connection during various positions, limiting user convenience and functionality.
Innovation Solution
A self-contained, motorized tilt drive device with a coupling mechanism that maintains a secure connection during tilting and allows manual operation by decoupling for rotation, featuring a separating element to disconnect during specific movements and a locking device to prevent unauthorized operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a tilt drive device with motorized drive and coupling mechanism is implemented, then operational flexibility and automation are improved, but device complexity increases
Solution Approach 1:
The patent combines the motorized drive unit, coupling mechanism with free passage, and separating element into a single integrated tilt drive device. This merging of functions into one compact unit provides multiple operating modes (manual and automatic tilting, manual closing) while managing complexity through unified design rather than separate mechanisms.
Solution Approach 2:
The tilt drive device is designed to perform multiple functions: it enables automatic tilting when coupled to the sash locking mechanism, manual tilting when decoupled, and manual closing of the sash. This multi-functionality achieves operational flexibility without requiring entirely separate systems for each operation type.
2Ease of operation
If a coupling mechanism with free passage is used to allow manual rotation, then ease of operation is improved, but reliability of coupling connection deteriorates
Solution Approach 1:
The coupling mechanism dynamically adapts its state based on operating mode. During automatic tilting, the coupling is engaged and rigid for reliable force transmission. During manual rotation, the coupling is decoupled allowing free passage. This dynamic switching maintains reliability when needed while enabling ease of operation when required.
Solution Approach 2:
The sash locking mechanism serves as an intermediary element between the tilt drive device and the sash. The coupling mechanism interacts with the sash locking mechanism to establish or release the coupling connection, providing a controlled interface that ensures reliable connection during automatic operation while allowing easy decoupling for manual operation.
3Reliability
If the tilt drive device is permanently coupled to the sash, then reliability is improved, but ease of operation deteriorates due to inability to manually rotate
Solution Approach 1:
The coupling mechanism is segmented into engageable and disengageable states. The free passage feature creates a segmented operational path where the coupling connection can be established for automatic tilting or opened for manual rotation. This segmentation allows the system to provide reliable coupling when needed while maintaining manual operability when required.
4Ease of operation
If a separating element is added to disconnect during specific movements, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The separating element is extracted as a distinct functional component within the coupling mechanism. It can be independently actuated to disconnect the coupling connection between the tilt drive device and the sash locking mechanism. This extraction allows manual operation capability to be added without requiring complete redesign of the entire drive system.

AI summary
The invention relates to a tilting drive device (14) for a wing (3) of a window (1) or the like, which can be rotated and tilted about bearing axes (5, 6) and has a rotating and tilting fitting (7) with a manual actuator (10) and a wing lock (12) which can be actuated therewith, the tilting drive device (14) having a dedicated drive (21) and a dedicated extension device (26) which can be connected or is connected to the wing (3), in particular to the wing lock (12). The tilting drive device (14) has a means (16) for coupling to the wing (3), said coupling means producing a coupled connection between the wing (3) and the tilting drive device (14) when the wing (3) is tilted about one bearing axis (5) by means of the tilting drive device (14) or by means of the manual actuator (10). The coupling means (16) has a release mechanism (18) which decouples the wing (3) from the tilting drive device (14) to rotate the wing (3) about the other bearing axis (6). The coupling means (16) can also produce a coupled connection between the wing (3) and the tilting drive device (14) when the wing (3) is in a locked closed position.
