Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical fiber cutters have complex mechanisms due to the need for rotating blade members, which complicates the wiring and increases the risk of mechanical failure and operational complexity.
Innovation Solution
An optical fiber cutter design where the blade member is rotatably fixed to a base, allowing power transmission only when the blade member moving base reaches a predetermined position, and featuring a manual operation rotating member for user-driven rotation, simplifying the mechanism and reducing wiring complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the blade member is rotated by a motor-driven cam mechanism, then the blade member can be rotated to change the contact portion, but the mechanism becomes complicated and wiring length increases
Solution Approach 1:
The invention extracts the rotation function from the complex motor-driven cam mechanism and implements it through a simple rotating member that can be manually operated. The blade member is rotatably supported by a rotating member, allowing the contact portion to be changed by simple rotation without requiring complex driving mechanisms.
Solution Approach 2:
The blade member is designed to be rotatable on its own through the rotating member, enabling self-service rotation without external motor-driven cam mechanisms. The operator can directly rotate the blade member to change the contact portion, eliminating the need for complex automated rotation systems.
2Adaptability or versatility
If the blade member is rotated by a motor-driven cam mechanism, then the blade member can be rotated to change the contact portion, but the wiring connected to the motor must be lengthened
Solution Approach 1:
The invention removes the motor-driven cam mechanism and its associated wiring from the system. Instead, the blade member is rotated manually through a rotating member, eliminating the need for extended wiring to reach the moving blade member.
Solution Approach 2:
The blade member rotation is achieved through manual operation of the rotating member, which serves itself without requiring external motor power and wiring. This self-service approach eliminates wiring length issues entirely.
3Ease of operation
If power transmission is always engaged between the rotating member and blade member, then rotation is automatic, but mechanical stress on the driving source increases
Solution Approach 1:
The power transmission mechanism is designed to be dynamic, automatically engaging and disengaging based on the operational state. The clutch mechanism engages power transmission when the blade member needs rotation and disengages when not needed, reducing mechanical stress on the driving source while maintaining ease of operation.
Solution Approach 2:
The system incorporates feedback through the clutch mechanism that responds to operational conditions. When the blade member reaches a predetermined position or operational requirements are met, the clutch automatically disengages, reducing mechanical stress. This feedback-based control allows automatic rotation when needed while minimizing unnecessary mechanical load.
4Extent of automation
If only motor-driven rotation is provided, then automation is high, but reliability decreases when motor fails
Solution Approach 1:
The system provides dual rotation modes - automatic motor-driven rotation and manual rotation - changing the operational parameter based on needs. When the motor fails, the system can switch to manual rotation through the rotating member, maintaining operational reliability while preserving automatic rotation capability for normal operation.
Solution Approach 2:
The system prepares for motor failure by providing a manual rotation backup mechanism beforehand. The rotating member and clutch mechanism are designed to allow manual operation, cushioning against the reliability risk of motor failure and ensuring continuous operation capability.

AI summary
An optical fiber cutter includes a base that includes a pair of clamps, a blade member moving base that includes a disk-shaped blade member and is configured to move the blade member and bring an outer circumferential edge of the blade member into contact with a surface of the optical fiber, and a pressing that press-bends a scratched portion of the optical fiber to cut the optical fiber. The blade member is rotatably fixed to the blade member moving base to change a position of the outer circumferential edge to be in contact with the optical fiber. The base further includes a rotating member that is rotatably fixed to the base and configured to rotate to transmit power to rotate the blade member, and power transmission between the blade member and the rotating member is releasable.
