Optical Module Unlocking Mechanism with Non-Force-Transmitting Crossbeam
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical modules face challenges with unlocking mechanisms, particularly due to deformation of handle crossbeams under force, leading to unlocking difficulties and non-compliance with Multi-Source Agreement (MSA) standards.
Innovation Solution
The optical module incorporates an unlocking mechanism with a handle and unlocker, where the unlocking surface and positioning hole are arranged on the same vertical surface, and the crossbeam structure does not transmit force between the handle and unlocker, ensuring reliable unlocking and compliance with MSA standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the crossbeam structure transmits force between the handle and unlocker, then the structure is simplified, but the crossbeam deforms under force leading to unlocking failures
Solution Approach 1:
The patent divides the force transmission path by separating the crossbeam from the force transmission function. The crossbeam is segmented into a non-force-transmitting structural element, while force is transmitted through dedicated transmission components like the unlocking surface and positioning hole arrangement, preventing deformation while maintaining structural simplicity.
Solution Approach 2:
The patent extracts the force transmission function from the crossbeam structure. The crossbeam retains only its structural support role, while force transmission is handled by separate components (unlocking surface, positioning hole, and their geometric arrangement), eliminating the deformation problem while preserving structural integrity.
2Adaptability or versatility
If the unlocking surface and positioning hole are arranged on different surfaces, then the handle structure is more flexible, but unlocking reliability decreases
Solution Approach 1:
The patent merges the unlocking surface and positioning hole onto the same vertical surface of the handle. This geometric merging ensures that force applied to the unlocking surface is directly aligned with the positioning hole, creating a reliable force transmission path that guarantees unlocking functionality while maintaining handle structural flexibility.
3Device complexity
If the crossbeam transmits force, then fewer components are needed, but MSA standards compliance is violated
Solution Approach 1:
The patent introduces an intermediary force transmission mechanism between the handle and unlocker. Instead of direct crossbeam force transmission, force is transmitted through the unlocking surface and positioning hole arrangement as intermediaries, which comply with MSA standards while achieving the same functional result with appropriate component configuration.

Function Achieved in This Case
This design guarantees reliable unlocking functionality and ensures that the optical module meets MSA standards, preventing deformation-induced unlocking issues and enhancing operational reliability.
Implementation Method 1
a return spring arranged in an accommodation cavity of the unlocker movement guiding structure, and the return spring connects the unlocker and the shell... the applied force drives the unlocker to slide and compress the return spring until locking on the positioning protrusion by an external device is unlocked during an unlocking process; and after the unlocking process, as the applied force is removed, the compressed return spring drives the unlocker to slide on the shell

AI summary
An optical module comprising: a shell having an unlocker movement guiding structure, a positioning protrusion and a first pivotable positioning member; and an unlocking mechanism connected to the shell and comprises a handle and an unlocker, the handle has a second pivotable positioning member and an unlocking surface, a return spring is arranged in an accommodation cavity of the unlocker movement guiding structure, one end of the unlocker is inserted into the accommodation cavity, and an opposite end contacts the unlocking surface, such that a force applied when the handle is rotated drives the unlocker to slide on the shell, which drives the unlocker to compress the return spring until locking on the positioning protrusion is unlocked, and as the applied force is removed, the return spring drives the unlocker to slide, which then drives the handle to rotate back.
