Optical Module Latch Fitting De-latching Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional de-latching mechanisms for optical modules require a large angle of lift, which can lead to damage when attempting to remove the module from a socket, and lack versatility in de-latching operations.
Innovation Solution
A latch fitting with a tapered end, latch body, and latch tail that can rotate around a spindle, incorporating angled stand bars and a surface plate for de-latching, along with a pull-tab and sliding grooves to facilitate de-latching through a combination of sliding and rotating movements, allowing for multiple de-latching actions with a reduced rotation angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional de-latching mechanism uses a lever with a tapered end requiring large angle lifting, then the de-latching action can be performed, but the risk of damage to the tapered end, cage, or socket increases
Solution Approach 1:
The latch tail is divided into multiple segments: a first de-latching portion with tilted stand bars for sliding movement, and a second de-latching portion with a surface plate for rotation. This segmentation allows the de-latching function to be achieved through multiple independent motion paths, reducing the risk of damage while maintaining operational ease.
Solution Approach 2:
The latch fitting is designed to rotate around a spindle, transforming the static lever mechanism into a dynamic rotating system. The pull rod can drive the latch tail through sliding grooves in a rotating manner, converting the large-angle lifting motion into a controlled rotational sliding motion that reduces damage risk.
2Ease of operation
If the pull-tab is lifted at a large angle to rotate the lever, then de-latching can be achieved, but the operation becomes more complex and time-consuming
Solution Approach 1:
The de-latching process is divided into periodic actions: the pull rod first slides along the sliding grooves to drive the tilted stand bars, then rotates to engage the surface plate. This periodic sequence of sliding and rotating actions streamlines the de-latching process, making it faster and easier to perform.
3Adaptability or versatility
If a single de-latching method is used, then the mechanism is simple, but the adaptability to different de-latching needs is reduced
Solution Approach 1:
The latch tail incorporates multiple de-latching portions that can perform different functions: the tilted stand bars enable sliding de-latching, while the surface plate enables rotational de-latching. This multi-functionality design allows the same latch mechanism to adapt to different de-latching scenarios without increasing overall complexity.
