Two-Way Latch Mechanism for Convertible Panel Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional latch mechanisms for portable computers are complex, occupy valuable mechanical space, and lack the capability for two-way latching, which is essential for convertible computers that can rotate 180 degrees and function in multiple modes.
Innovation Solution
A two-way latch mechanism featuring a pivotally disposed hook inside the host that engages with different holes on the panel at various positions, an actuating component with sliding pushing portions, resilient components for recovery force, and a magnetic component for stable operation, allowing dual directional locking and secure constraining of the panel relative to the host.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional latch mechanism with link and pin is used, then the monitor and host can be latched, but the device complexity increases and mechanical space is occupied
Solution Approach 1:
The patent combines the movable component and fixing component into a single integrated latch mechanism. The hook structure integrates both the movable element (hook body) and fixing element (engagement surfaces) into one component, eliminating the need for separate link and pin components while maintaining the latching function.
Solution Approach 2:
The latch mechanism is designed to perform multiple functions: it can latch the panel to the host in the closed position, and also latch them when the panel is rotated 180 degrees. The hook structure with its engaging surfaces can engage with different positions on the panel, providing universal latching capability for both notebook and tablet modes.
2Reliability
If conventional latch mechanism components are disposed on the host, then the latching function is achieved, but the mechanical space in the host is occupied
Solution Approach 1:
The latch mechanism components are nested within the existing structural spaces of the host and panel. The hook is disposed inside the host structure, utilizing the available internal volume without requiring additional external space. The engaging surfaces are integrated into the panel's existing structure, allowing the latch mechanism to fit within the boundaries of the display assembly.
3Adaptability or versatility
If the panel can rotate 180 degrees for convertible modes, then the adaptability increases, but the conventional latch mechanism cannot provide two-way latching
Solution Approach 1:
The latch mechanism employs asymmetric engaging surfaces on the hook structure. The first engaging surface is positioned to engage with the panel in the closed position, while the second engaging surface is positioned to engage with the panel when rotated 180 degrees. This asymmetric design allows the same hook structure to provide reliable latching in both orientations without requiring separate latching mechanisms.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The mechanism provides secure dual directional locking, constrains relative movement, and maintains operational convenience by allowing the panel to cover the host in two opposite directions, enhancing usability in convertible computer modes.
Implementation Method 1
two resilient components respectively disposed on two ends of the actuating component and installed inside the panel for providing resilient recovering force to the actuating component
Implementation Method 2
a magnetic component disposed inside the host for sliding the protrusions on the constraining component between the sliding slot and the constraining slot on the positioning component

AI summary
A two-way latch mechanism includes a hook disposed inside a host for engaging with a first hole on a panel and for engaging with a second hole on the panel after the panel rotates relative to the host at 180 degrees. The two-way latch mechanism further includes an actuating component. Two pushing portions are respectively disposed on two sides of the actuating component. One of the pushing portions slides at a first direction for separating the hook from the first hole, and the other slides at the first direction for separating the hook from the second hole. The two-way latch mechanism further includes two elastic components for respectively providing elastic forces on the actuating component, so as to hold the actuating component at a predetermined position stably.
