Modular Window Locking Mechanism for Flexible Sash Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window and door systems with central locks are complex, expensive, and limited in operating options, particularly when requiring both rotational and tilting movements for ventilation, and often compromise on visual design due to the presence of a central locking mechanism.
Innovation Solution
A window or door system equipped with modular individual closures, each with independent actuating sections that can be coupled for synchronous operation via a common operating element, allowing for various movement paths such as rotation, tilting, or sliding without the need for a complex tilting mechanism, and featuring magnetic coupling for intuitive operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a central locking system is used to secure multiple fixing points simultaneously, then the locking mechanism is simplified and can be operated with a single actuation, but the device complexity increases due to the need for a central actuation section and connecting rod arrangement
Solution Approach 1:
The locking system is divided into multiple independent modular individual closures, each responsible for a specific fixing point. Each closure has its own actuating section that can be operated independently or coupled with others, eliminating the need for a complex central actuation mechanism while maintaining the ability to secure multiple points simultaneously.
2Productivity
If a central locking system with connecting rod arrangement is implemented, then all locking pins can be engaged or disengaged simultaneously, but the manufacturing cost increases
Solution Approach 1:
Instead of manufacturing one complex central locking system, the patent uses multiple simple modular individual closures that can be manufactured separately and assembled independently. This segmentation reduces manufacturing complexity and cost while maintaining the capability to engage all locking points simultaneously through coupling of the modular units.
3Adaptability or versatility
If a tilting mechanism is added to enable ventilation, then the operating versatility is improved, but the device complexity and cost increase significantly
Solution Approach 1:
The system provides dynamic versatility by allowing different combinations of modular individual closures to be actuated simultaneously. By selectively coupling and actuating different modules, the sash can achieve various movement paths including rotation, tilting, and sliding without requiring a dedicated mechanical tilting mechanism, thus maintaining simplicity while enhancing adaptability.
4Adaptability or versatility
If modular individual closures with independent actuating sections are used, then the operating versatility and flexibility are improved, but the device complexity increases due to multiple independent components
Solution Approach 1:
The modular individual closures can be coupled together through their actuating sections to function as a unified system. This merging allows multiple components to operate cooperatively, achieving complex movement paths and operational versatility while presenting a simplified interface to the user, effectively combining the benefits of modularity with system integration.

AI summary
A window or door comprises a frame and a sash movable relative to the frame, the sash being fixable to the frame by a locking mechanism with multiple fixing points. The locking mechanism includes several modular individual locks for selectively moving the sash along one of several different movement paths, each lock being assigned to one of the multiple fixing points. Each modular individual lock has independent actuation sections by means of which the sash can be released from its respective fixing point.
