Sliding Window Motor Drive Automatic Unlocking Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorized drive systems for sliding windows lack the ability to automatically unlock the opening relative to the frame after a manual movement from a locked ajar position, posing safety risks and hindering quick access or exit, especially in emergency situations.
Innovation Solution
A method and system that includes an electromechanical actuator with an electronic control unit and counting device, which automatically starts the electric motor to unlock the first locking device after manual movement to the locked ajar position, allowing for automatic deactivation of the locking mechanism without external command, enabling safe and quick opening or closing of the window.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the first locking device maintains the opening in the locked ajar position after manual movement, then the window provides secure ventilation positioning, but the window cannot be quickly opened or closed in emergency situations
Solution Approach 1:
The control unit automatically detects manual movement of the opening and triggers the electromechanical actuator to unlock the first locking device and move the opening to a desired position without requiring external intervention. The system serves itself by monitoring its own state and initiating appropriate actions.
Solution Approach 2:
The counting device continuously monitors the position of the opening relative to the frame, preparing the control unit with advance information about manual movement. This preliminary detection enables the system to respond immediately when the opening is moved from the locked ajar position.
2Extent of automation
If the electromechanical actuator requires external command to unlock, then the system maintains precise control, but the system cannot respond automatically to manual movement
Solution Approach 1:
The counting device provides continuous feedback about the opening position to the control unit. When the control unit detects that the opening has been manually moved from the locked ajar position, it automatically triggers the electromechanical actuator to unlock and reposition the opening, creating a closed-loop automatic control system.
Solution Approach 2:
The control unit performs multiple functions: it monitors the opening position via the counting device, detects manual movements, decides when unlocking is needed, and commands the electromechanical actuator. This multi-functionality reduces the need for separate dedicated components for each function.
3Ease of operation
If the window remains locked in the ajar position, then security is maintained, but user safety and convenience are compromised in emergency situations
Solution Approach 1:
The locking system transitions from a static locked state to a dynamic responsive state. The control unit continuously monitors opening position and automatically adjusts the locking state based on detected manual movements, making the security system adaptive rather than fixed.
Solution Approach 2:
The system preemptively unlocks the first locking device when it detects manual movement, preventing the harmful situation where the window remains locked during emergencies. By anticipating the user's need to open or close the window quickly, the system eliminates the security risk before it becomes a problem.

AI summary
A method for controlling the operation of a motorized drive device for a sliding window for a building includes a first movement step (E10) of an opening relative to a fixed frame from an open position to a locked half-open position, implemented manually, without electrically activating an electric motor of an electromechanical actuator, and a determination step (E30) of the manual movement and the attainment of the locked half-open position, by means of a counting device.Following the determination of the manual movement and the attainment of the locked half-open position, the method includes an automatic start-up step (E50) of the electric motor of the electromechanical actuator by means of an electronic control unit, so as to unlock a first locking device by movement of the opening relative to the fixed frame, implemented by the electrical activation of the electric motor.
