Latch Mechanism Inverting Rotation to Release Meshing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing latch mechanisms require a region for rotating the moving unit to release meshing, which is not always feasible in all configurations, especially when a moving force is transmitted to the moving unit by operating an operation unit.
Innovation Solution
A latch mechanism design that includes an operation unit, a connection unit extending in one direction with one end connected to the operation unit, a restriction unit to move the other end of the connection unit to one side, and a moving unit that moves from a first position to a second position as the connection unit moves, allowing meshing and release without rotating the moving unit.

Engineering Contradiction Analysis
1Reliability
If the moving unit rotates to release meshing with the meshing unit, then the meshing can be released, but a region for rotating the moving unit is required which increases device complexity and is not always feasible in all configurations
Solution Approach 1:
Instead of rotating the moving unit to release meshing, the invention inverts the approach by keeping the moving unit stationary and rotating the meshing unit. This inversion eliminates the need for additional rotation space while achieving the same meshing release function. The connection unit transmits force to rotate the meshing unit relative to the moving unit, thereby releasing the meshing engagement without requiring the moving unit to rotate.
Solution Approach 2:
The invention introduces a connection unit as an intermediary element between the operation unit and the moving unit. This connection unit transmits the operational force to rotate the meshing unit rather than the moving unit itself. By using this intermediary mechanism, the system achieves meshing release without requiring the moving unit to rotate, thus reducing space requirements and simplifying the overall device configuration.
2Ease of operation
If the moving unit rotates to release meshing, then the latch mechanism functions, but the configuration is not suitable when moving force is transmitted through an operation unit
Solution Approach 1:
The connection unit serves as an intermediary that adapts the force transmission from the operation unit to the meshing unit. This intermediary mechanism allows the system to maintain good operability through the operation unit while avoiding the need for the moving unit to rotate, thereby improving configuration compatibility across different application scenarios.
Solution Approach 2:
By inverting which component rotates (meshing unit instead of moving unit), the system achieves better operability compatibility with force transmission through an operation unit. This inversion allows the moving unit to remain stationary while still achieving effective latch release through the rotated meshing unit.
3Device complexity
If the moving unit is kept stationary to avoid rotation space, then device complexity is reduced, but a method to release meshing without rotation is needed
Solution Approach 1:
The invention directly addresses this challenge by inverting the rotation approach: instead of rotating the moving unit, the meshing unit is rotated relative to the stationary moving unit. This inversion maintains space efficiency while providing a reliable meshing release mechanism through the rotational movement of the meshing unit alone.
Solution Approach 2:
The connection unit acts as an intermediary that enables the meshing release function without requiring the moving unit to rotate. It transmits the operational force to rotate the meshing unit, thereby maintaining both space efficiency and reliable meshing release capability.
