Optical Fiber Blade Rotation Angle for Wear Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing optical fiber cutter's blade member position changes only by one tooth rotation, leading to uneven contact with the optical fiber, resulting in reduced blade life.
Innovation Solution
An optical fiber cleaving apparatus that rotates the blade member by a predetermined angle not divisible by 360 degrees, ensuring non-overlapping contact points with the optical fiber, thereby extending the blade's lifespan.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the blade member is rotated by an angle corresponding to one tooth of the rotating body, then the position of the blade member changes, but the blade life is reduced due to uneven contact with the optical fiber
Solution Approach 1:
The patent applies asymmetry by using a rotation angle that does not evenly divide 360 degrees (e.g., 17 degrees instead of 15 or 20 degrees). This asymmetric rotation ensures that the blade member contacts different portions of the optical fiber in each rotation, distributing wear more evenly across the blade surface and extending blade life while maintaining operational effectiveness
2Device complexity
If the blade member contacts the optical fiber at the same position repeatedly, then the operation is simple, but the blade wears out quickly
Solution Approach 1:
The patent changes the rotation angle parameter from a conventional value that divides 360 degrees evenly to a non-dividing value (such as 17 degrees). This parameter change ensures that the blade member progressively contacts different segments of the optical fiber, distributing mechanical stress and wear across the entire blade surface, thereby extending blade life without complicating the rotation control mechanism

AI summary
An optical fiber cleaving apparatus for cutting an optical fiber includes a blade member configured to damage the optical fiber, and a rotation mechanism configured to rotate the blade member by a predetermined angle each time the blade member damages the optical fiber. The predetermined angle is a numerical value that is not capable of dividing 360.
