Motorized Window Closure with Wireless Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window and door closures require manual effort for final locking and are not visually appealing, with a need for improved ease of operation and aesthetics.
Innovation Solution
A motorized closure system with a wireless signal transmission unit that automatically moves the closure element into a blocking position upon activation, eliminating the need for manual handling and incorporating a pawl mechanism for secure locking and unlocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a manual handle mechanism is used for final locking, then the locking function is reliable, but the ease of operation deteriorates and visual appeal is reduced
Solution Approach 1:
The patent replaces the manual mechanical handle system with an electric motor (28) that automatically actuates the closure element (15) into the blocking position. This substitution eliminates the need for manual operation while maintaining reliable locking, directly resolving the contradiction between operational ease and locking reliability.
2Reliability
If a manual handle mechanism is used for final locking, then the locking function is reliable, but the visual appeal deteriorates
Solution Approach 1:
By replacing the visible manual handle with an integrated electric motor (28) and automated closure element (15), the invention achieves clean, handle-free aesthetics while maintaining reliable locking through the motor-driven blocking mechanism.
3Reliability
If multiple closures are operated independently, then each closure functions reliably, but the productivity deteriorates due to manual operation of each
Solution Approach 1:
The patent implements a central control unit (43) that can simultaneously control multiple electric motors (28) across different closures, enabling synchronized operation. This multi-functional control system maintains individual closure reliability while dramatically improving overall productivity by allowing batch operation of multiple closures.
4Ease of operation
If the closure element is automatically moved into blocking position, then the ease of operation is improved, but the device complexity increases due to motor integration
Solution Approach 1:
The electric motor (28) is integrated into the existing closure mechanism, serving dual functions: it acts as both the actuation mechanism for moving the closure element (15) and as part of the overall locking system. This multi-functional integration improves ease of operation while minimizing the increase in device complexity by reusing existing structural elements.

AI summary
A window or door lock comprises a base body and a locking element mounted on the base body. This locking element defines a receptacle for a bolt and is movable between a release position and a locking position. When the lock is installed, the locking element is automatically moved from the release position towards the locking position by a closing movement of the sash. It can be locked to the base body in at least one interlocking position between the release and locking positions, preventing movement of the locking element towards the release position while allowing movement towards the locking position. A motor mounted on the base body is designed to actuate the locking element in the interlocking position upon activation, causing it to move into the locking position.
