Transceiver Latch and Torsion Spring for Easier Cage Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional small form factor pluggable transceiver modules require inconvenient detaching processes, where the fiber must be removed before the handle is rotated to sink the wedging protrusion into the housing, making separation from the cage cumbersome.
Innovation Solution
A transceiver module design incorporating a housing, a latch, and a torsion spring with a positioning post and block, where the latch applies a pushing force to the torsion spring, allowing the wedging protrusion to move from a first to a second position, enabling easy separation by pulling the handle, enhancing movement reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the conventional detaching process is used where the fiber must be removed first and then the handle is rotated to sink the wedging protrusion, then the transceiver module can be separated from the cage, but the detaching process becomes inconvenient and cumbersome
Solution Approach 1:
The patent combines the fiber removal function and the latch release function into a single integrated operation. The groove structure on the handle allows the extraction tool to simultaneously engage both the fiber and the latch mechanism, enabling both actions to occur during one pulling motion rather than requiring separate steps.
Solution Approach 2:
The groove structure on the handle acts as an intermediary mechanism that mediates between the extraction tool and the internal components (fiber and latch). This groove allows the extraction tool to apply force that simultaneously pulls the fiber and actuates the latch release, simplifying the user's interaction with the complex internal mechanisms.
2Ease of operation
If the wedging protrusion is designed to sink into the housing by rotating the handle, then the transceiver module can be separated from the cage, but the movement reliability of the wedging protrusion is reduced
Solution Approach 1:
The torsion spring automatically resets the latch mechanism to its engaged position after the transceiver module is inserted. The spring stores energy during the release operation and automatically returns the wedging protrusion to its latching position, eliminating the need for manual resetting and ensuring reliable re-engagement without additional user actions.
Solution Approach 2:
The patent introduces dynamic elements including the torsion spring that provides elastic recovery and the movable latch that transitions between engaged and disengaged states. These dynamic components ensure reliable movement and resetting of the wedging protrusion, maintaining both operational ease and movement reliability.
3Reliability
If a latch mechanism with torsion spring is introduced to improve wedging protrusion reliability, then the movement reliability is improved, but the device complexity increases
Solution Approach 1:
The latch mechanism is segmented into distinct functional components: the wedging protrusion for engagement, the torsion spring for energy storage and automatic resetting, and the groove structure on the handle for controlled actuation. This segmentation allows each component to perform its specific function efficiently while maintaining overall system reliability without excessive complexity.
