Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fiber adapters require manual management of dustproof caps, causing inconvenience during use and potentially affecting performance due to dust exposure and laser safety concerns.
Innovation Solution
A fiber adapter design featuring a dustproof cover that can be locked in a horizontal position, unlocked during connector insertion, and automatically closed during removal, utilizing a rotary spring and inclined blocks for one-handed operation, ensuring dustproofing without affecting optical or mechanical performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If dustproof caps are directly inserted at two ends of a fiber adapter, then dustproof effect is achieved, but manual management is required causing inconvenience in use
Solution Approach 1:
The dustproof cap is merged with the fiber adapter body through a hinged connection, allowing the cap to remain attached during use while providing dustproof protection. This eliminates the need for separate management of dustproof caps while maintaining their protective function.
Solution Approach 2:
The dustproof cap is designed with a hinged structure that allows it to dynamically change between closed (dustproof) and open (access) positions. The cap can be automatically opened when a connector is inserted and automatically closed when the connector is removed, providing adaptive dustproof protection without manual intervention.
2Object-affected harmful factors
If dustproof caps are manually mounted, then dustproof effect is maintained, but separate management is required causing inconvenience
Solution Approach 1:
The dustproof cap is integrated with the fiber adapter body through a hinged connection mechanism, combining what were previously separate components (cap and adapter) into a single unified structure. This eliminates the need for separate management while maintaining dustproof functionality.
Solution Approach 2:
The dustproof cap automatically performs its function of protecting the adapter interior without requiring manual mounting or management. The hinged structure with spring mechanism allows the cap to self-open when a connector is inserted and self-close when the connector is removed, providing autonomous dustproof protection.
3Ease of operation
If a hinged dustproof cover is used, then one-handed operation is enabled, but the cover needs to be locked in horizontal position
Solution Approach 1:
The dustproof cap employs a hinged connection that enables dynamic movement between closed and open positions, facilitating one-handed operation. The cap can be easily opened by pushing with one hand when a connector is inserted and automatically closes when the connector is removed.
Solution Approach 2:
The spring mechanism provides automatic locking and unlocking functionality without requiring manual intervention. When the dustproof cap is opened, the spring stores energy and automatically locks the cap in the horizontal position. When the connector is removed, the spring automatically closes and locks the cap back in place, enabling self-service operation.

AI summary
A fiber adapter includes a dustproof cap (1), a first adapter body (2), and a second adapter body (5), where the fiber adapter further includes a dustproof cover (8), a rotary spring (7), and inclined blocks (7). The dustproof cover (8) is mounted at one end of the second adapter body (5) by using the rotary spring (7). The inclined block (6) is embedded into a bottom surface of the second adapter body (5) through a hole (5b) provided in the bottom surface of the second adapter body (5), and the inclined block (6) can vertically slide through the hole (5b). In embodiments of the present invention, components such as a dustproof cover, a rotary spring, and inclined blocks are added to an existing universal fiber adapter to form a novel fiber adapter. The novel fiber adapter is convenient in management while having a dustproof effect, and is more practical.
