Optical Connector Cleaning Tool Axial Rotation Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical connector cleaning tools are cumbersome, difficult to operate, and lack effective downsizing, with existing solutions requiring alignment and motor-driven mechanisms that complicate the design and increase size.
Innovation Solution
A compact optical connector cleaning tool that simplifies operation by using a feeding mechanism with a head member that rotates axially through relative movement with the insertion part, allowing easy insertion into a connector housing hole and rotation in successive actions, featuring guide openings to prevent the cleaning body from falling off and ensuring reliable cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a motor-driven rotary mechanism is used to rotate the cleaning pin, then the cleaning function is achieved, but the device size becomes large and operation becomes complex
Solution Approach 1:
The patent extracts the motor from the system entirely, replacing it with a manual operation mechanism. The cleaning pin is rotated by hand through a simple rotary operation, eliminating the need for motors, batteries, or complex drive mechanisms while maintaining the cleaning function.
Solution Approach 2:
The cleaning tool is designed to be self-operating without external power sources. The user's manual rotation of the head member directly drives the cleaning pin, making the system self-sufficient and eliminating complex mechanical transmission components.
2Ease of operation
If a motor-driven rotary mechanism is used to rotate the cleaning pin, then the cleaning function is achieved, but the overall device size becomes large
Solution Approach 1:
The motor and associated power supply components are completely removed from the device. The head member is rotated manually by the user, reducing the device to essential components only: the body, insertion part, cleaning pin, and guide openings.
Solution Approach 2:
The device uses the user's manual input directly to operate the cleaning mechanism without intermediate power conversion components, minimizing the device volume to only what is necessary for the cleaning function.
3Device complexity
If the cleaning body is allowed to move freely on the pressing face, then the mechanism is simple, but the cleaning body may fall off and cleaning reliability decreases
Solution Approach 1:
The pressing face is designed with localized guide openings at specific positions to guide and constrain the cleaning body. These openings are strategically placed to prevent the cleaning body from falling off while maintaining a simple overall mechanism without complex retention systems.

AI summary
An optical connector cleaning tool which wipes to clean a joining end face of an optical connector by a feeding movement of a cleaning body. It includes a tool body which incorporates a feeding mechanism that supplies and takes up the cleaning body, and an insertion part which inserts into a connector housing hole of a positioning housing for connectors. The insertion part has a head member on which is formed a pressing face that presses the cleaning body against the joining end face within the connector housing hole, and is capable of moving in a direction of extension or contraction relative to the tool body.Movement of the tool body in an insertion direction relative to the insertion part in a state where the cleaning body is in contact with the joining end face causes the head member to axially rotate while the state of contact is maintained.
