Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical fiber cutting devices face challenges in automatically returning the slider to its initial position after cutting, with complex magnetic configurations and room for simplification.
Innovation Solution
An optical fiber cutting device with a main body and a moving part having a blade portion, where the moving part is moved between two positions using a repulsive force generated by the interaction between a first magnet and a second magnet, with the second magnet positioned closer to the initial position, allowing for automatic return without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If multiple magnets are used to automatically return the slider to the initial position, then the automation is improved, but the device complexity increases
Solution Approach 1:
The patent extracts only the essential magnetic interaction needed for automation by using just two magnets (first magnet on main body, second magnet on slider) instead of multiple magnets. The second magnet is positioned closer to the initial position than the first magnet, creating a repulsive force that automatically returns the slider to its initial position after cutting, achieving automation with minimal magnetic components.
2Force
If the second magnet is positioned closer to the first position, then the repulsive force for automatic return is improved, but the risk of damage to the optical fiber increases
Solution Approach 1:
The patent applies local quality by positioning the second magnet at a specific location on the slider that is closer to the initial position than the first magnet on the main body. This localized positioning creates a concentrated repulsive force in the critical region near the initial position, ensuring strong automatic return force while maintaining safe distance from the optical fiber cutting area.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables a simple configuration for automatic return of the moving part to the initial position after cutting, reducing the risk of damage to the optical fiber and improving workability.
Implementation Method 1
the slider is moved in a direction of the third magnet by the repulsive force between the first magnet and the second magnet
Implementation Method 2
the slider is stopped at an initial position by the attractive force between the first magnet and the third magnet

AI summary
An optical fiber cutting device comprising: a main body having a positioning portion configured to position the optical fiber and a first magnet; and a moving part having a blade portion configured to put a scratch on the optical fiber and a second magnet, and attached to the main body to be movable between a first position and a second position, wherein the blade portion is capable of putting a scratch on the optical fiber while the moving part is moved from the first position to the second position, and wherein when the moving part is located at the second position, the second magnet is located at a position at which the respective same polarity sides of the second magnet and the first magnet face each other and which is closer to the first position than the first magnet.
