Motorized Sliding Window Locking for Secure Ajar Ventilation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding window locking devices require manual operation and are not compatible with motorized drive systems, limiting their integration into home automation systems and preventing secure, half-open ventilation positions.
Innovation Solution
A sliding window system with a motorized drive device and dual locking mechanisms, allowing the sash to be locked in a half-open position electronically, using an electromechanical actuator, flexible element, and drive arm to coordinate the locking and unlocking processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electrical installations are integrated into sliding windows, then home automation functionality is improved, but device complexity increases
Solution Approach 1:
The electrical installation is divided into modular components: a power supply unit with rechargeable battery, separate motor units for driving different window elements, and independent control modules. Each motor unit can be independently replaced or programmed, allowing complex functionality to be achieved through simple, replaceable modules rather than a monolithic complex system.
Solution Approach 2:
The control unit is designed to be programmable and adaptable to perform multiple different functions. The same basic control hardware can be configured through software to implement various home automation scenarios, eliminating the need for separate dedicated hardware for each function and reducing overall system complexity.
2Use of energy by moving object
If a rechargeable battery is integrated into the sliding window, then energy autonomy is improved, but device complexity increases
Solution Approach 1:
The rechargeable battery system is designed to be recharged in place through connection to external power sources without requiring removal or replacement of the battery. The system automatically manages charging cycles and power distribution, eliminating the need for user intervention in power supply maintenance and reducing operational complexity.
3Adaptability or versatility
If the sliding window is equipped with multiple motors for different functions, then functionality is improved, but device complexity increases
Solution Approach 1:
The motor system is designed with programmable control that can dynamically assign different functions to different motor units based on operational requirements. The same physical motor configuration can be reprogrammed to perform different sequences of operations, allowing versatile functionality without adding permanent hardware complexity.

AI summary
A sliding window (2) comprises a fixed frame (4), an operable sash (3a, 3b), a first device (20) for locking in an ajar position, a motor drive device (5) for sliding the operable sash (3a) and a second device (21) for locking in a closed position. The drive device (5) comprises a drive arm (18), connected to the operable sash (3a) and to a flexible element (9) and engages with a movable arm of the first locking device. The movable arm holds the drive arm (18) between the ajar and closed positions, following passage beyond the ajar position, upon movement of the operable sash from an open position. A device for releasing the movable arm is activated following locking of the operable sash in the closed position.
