Segmented Latching Mechanism for Panel Security and Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing latching mechanisms for moveable panels, such as doors and windows, lack durability, burglar-proof security, and fire resistance, and often require significant space while providing weak latching and poor isolation.
Innovation Solution
A latching mechanism featuring two aligned latches that extend along the entire lateral side of the panel, moving parallel to each other to provide a sturdy, burglar-proof, and fire-resistant seal, with guiding means to facilitate operation and integration into the panel design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a single latch mechanism is used, then the device complexity is reduced, but the latching strength and reliability are insufficient
Solution Approach 1:
The latch mechanism is segmented into two separate latches (first latch and second latch) positioned at different locations on the panel. Each latch independently engages with the frame, distributing the latching force and providing redundant security. This segmentation resolves the contradiction by achieving stronger overall latching through multiple components rather than relying on a single complex mechanism.
2Reliability
If the latch length is increased to cover the entire lateral side, then the latching reliability and fire resistance are improved, but the space required and device complexity increase
Solution Approach 1:
Instead of using a single long latch extending across the entire lateral side, the invention distributes latching function across two shorter latches positioned vertically along the lateral side. This dimensional redistribution achieves comprehensive coverage and reliability while keeping each individual latch compact, thus reducing the overall volume occupied by the latching mechanism.
3Reliability
If the latches are made burglar-proof and durable, then the strength and reliability are improved, but the ease of operation and manufacturing difficulty are reduced
Solution Approach 1:
The burglar-proof functionality is achieved through segmentation into two separate latches rather than one complex heavy-duty latch. Each latch can be manufactured using standard, well-established processes, making production easier and more cost-effective while collectively providing superior security and durability compared to a single complex mechanism.

AI summary
An assembly comprising a moveable panel, for example a swinging door or window, and a latching mechanism (10) for latching the panel (1) to at least one nearby element (2) in case the panel (1) is in a first, particularly closed, position, the latching mechanism (10) being provided with at least one first latch (11) and with operating means (13) for moving the latch (11) out of a first lateral side of the panel (1) from a panel-releasing position to a panel-latching position and vice-versa, wherein the at least one first latch (11) is dimensioned such that it extends along substantially the entire first lateral side of the panel (1).
