Interior Gate Latch Bar with Wire Connector for Covert Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gate latching systems fail to prevent sag and wear, leading to misalignment and degradation, allow undesired entry due to visible unlatching mechanisms, and do not support covert, one-handed operation for added security and ease of use.
Innovation Solution
A gate latching system with a latch bar mounted to the interior side of the gate, an operator lever, and a stiff wire connector, combined with a self-closing gate spring and decorative hatchway cover to conceal the operation, preventing inward gate opening and enabling single-handed operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional latch mechanism is used, then the gate can be secured, but the unlatching mechanism is visible enabling undesired entry
Solution Approach 1:
The latch mechanism is extracted from the visible exterior surface and relocated to the interior side of the gate. The operator lever remains accessible from the outside, but the actual latching components are hidden inside the gate structure, preventing visibility of the unlatching mechanism while maintaining security function.
Solution Approach 2:
An interior mounting surface on the gate serves as an intermediary structure to host the latch mechanism. This intermediate structure allows the latch to be positioned inside the gate while still enabling external operation through the operator lever, creating a separation between the operational interface and the latching mechanism.
2Ease of operation
If the latch mechanism is mounted on the exterior, then it is accessible, but it causes wear and tear on the gate leading to misalignment
Solution Approach 1:
The latch mechanism is extracted from the exterior mounting location and relocated to the interior side of the gate. This removes the wear and tear problem from the gate surface while maintaining operational accessibility through the operator lever that can be actuated from the outside.
Solution Approach 2:
Instead of mounting the latch on the exterior as in traditional designs, the invention inverts the mounting location to the interior side of the gate. This reversal of the conventional approach eliminates the wear and misalignment issues while preserving the ease of operation through external lever actuation.
3Ease of manufacture
If a simple latch is used, then it is easy to manufacture, but it cannot prevent the gate from opening in an inward direction beyond hinge strength
Solution Approach 1:
The latch bar is merged with the operator lever to form a single integrated component. This combination allows the latch to provide both latching function and inward opening prevention through its interaction with the stationary post, while maintaining relative simplicity in manufacture.
Solution Approach 2:
The gate opening prevention function is segmented into two components: the latch bar that engages with the stationary post to block inward opening, and the operator lever that provides the actuating mechanism. This segmentation allows each component to be optimized for its specific function while working together to provide comprehensive gate control.
