Electronic Device Latching Mechanism for Compact Self-Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing latching mechanisms for electronic devices are often large, expensive, and have reduced operability due to the lack of a simple locking and unlocking mechanism that does not require a pop-up spring, making them inefficient for compact designs.
Innovation Solution
A latching mechanism that includes a rotatable latch with a first engaging portion, a shaft support that moves between positions, a biasing portion to facilitate rotation, and a second engaging portion on the opposing unit, allowing for locking and unlocking through a combination of rotation and vertical movement, thereby eliminating the need for complex locking devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional latching mechanism with lock claw, latch, biasing device, and locking device is used, then the latch can be locked and unlocked, but the device becomes large-sized, expensive, and complex
Solution Approach 1:
The patent extracts and eliminates the locking device from the traditional latching mechanism. By removing this component, the invention simplifies the overall structure while maintaining the essential locking function through the biased latch that automatically engages with the lock claw, thereby reducing device complexity without compromising reliability
Solution Approach 2:
The latch is designed with a biasing device that provides automatic self-latching functionality. The biased latch automatically engages with the lock claw when the cover is closed, eliminating the need for a separate locking device to maintain the locked state, thus simplifying the mechanism while ensuring reliable locking
2Reliability
If a traditional latching mechanism with multiple components is used, then the latch can be locked securely, but the device size increases
Solution Approach 1:
The patent merges the locking and latching functions into a single integrated mechanism. The biased latch serves both as the locking element and the latching element, working in conjunction with the lock claw to provide secure locking without requiring separate locking and latching components, thereby reducing the overall volume of the mechanism
Solution Approach 2:
By removing the locking device from the traditional four-component mechanism, the patent reduces the number of parts and the overall volume occupied by the latching mechanism while maintaining secure locking through the simplified biased latch and lock claw arrangement
3Reliability
If a traditional latching mechanism is used, then the latch can be locked, but the operation becomes complex and less user-friendly
Solution Approach 1:
The biased latch provides automatic self-latching when the cover is closed, eliminating the need for users to manually engage locking mechanisms. The spring bias ensures the latch automatically engages with the lock claw, making the operation simple and intuitive while maintaining reliable locking
Solution Approach 2:
By removing the locking device that required manual operation to maintain the locked state, the patent simplifies user interaction to merely closing the cover, which automatically triggers the latching action through the biased latch, thereby improving ease of operation while preserving locking reliability

AI summary
A latching mechanism includes a latch provided to a first unit, provided with a first engaging portion at its tip, and is rotatable about a rotation shaft from a first rotation position to a second rotation position, a shaft support provided to the first unit, rotatably supporting the rotation shaft, and is movable between a first position and a second position, a biasing portion provided to the first unit, and biasing the shaft support in a direction from the first position to the second position, and a second engaging portion provided to a second unit, and is engageable with the first engaging portion. The first and second engaging portions engage when the second unit is closed with respect to the first unit, the shaft support lies at the second position, and the latch lies at the second rotation position.
