Optical Fiber Adapter Movable Door for Dust and IR Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optical fiber adapters lack dust-proof structures, and existing dust caps are inconvenient to manage, while high-intensity infrared light beams from optical fibers can cause vision damage if not properly shielded.
Innovation Solution
An optical fiber adapter with a movable door that opens and closes in response to connector plugging and unplugging, featuring a movable door structure with latches and a torsion spring for automatic opening and closing, and includes dust caps for unused ports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a movable door structure is added to the adapter, then dust protection and safety are improved, but device complexity increases
Solution Approach 1:
The patent applies a movable door structure that dynamically opens and closes based on connector insertion and removal. The door is coupled to the connector through a linkage mechanism, allowing it to automatically respond to connector movements. This dynamic behavior provides dust protection when the door is closed and enables access when the connector is inserted, resolving the contradiction between protection and usability.
Solution Approach 2:
The movable door system operates autonomously by coupling the door's movement to the connector's insertion and removal actions. When the connector is inserted, the door automatically opens; when the connector is removed, the door automatically closes. This self-service mechanism eliminates the need for separate manual operations to open/close the door, maintaining protection while simplifying user interaction.
2Object-affected harmful factors
If a movable door structure is added to the adapter, then safety against infrared light is improved, but device complexity increases
Solution Approach 1:
The movable door provides dynamic protection against high-intensity infrared light beams by closing automatically when the connector is removed. The door's movement is synchronized with connector insertion/removal, ensuring the port remains covered when not in use and opens only when needed. This dynamic shielding prevents accidental exposure to harmful infrared radiation without requiring additional complex safety mechanisms.
Solution Approach 2:
The door system performs safety protection autonomously by responding to connector status changes. When the connector is inserted, the door opens to allow signal transmission; when removed, it automatically closes to block infrared light. This self-service safety feature eliminates the need for separate safety mechanisms or user actions, reducing overall device complexity while maintaining protection.
3Reliability
If dust caps are used to cover unused ports, then dust protection is improved, but ease of operation deteriorates
Solution Approach 1:
The patent replaces static dust caps with a dynamic movable door that automatically responds to connector insertion and removal. The door is coupled to the connector through a linkage mechanism, allowing it to open when the connector is inserted and close when removed. This dynamic behavior eliminates the need for manual dust cap installation and removal, improving ease of operation while maintaining dust protection.
Solution Approach 2:
The movable door system performs dust protection autonomously by responding to connector status changes. When the connector is inserted, the door automatically opens to allow access; when removed, it automatically closes to prevent dust ingress. This self-service mechanism eliminates the need for separate dust cap operations, significantly improving manageability while maintaining protection.
