Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optical fibers experience significant optical loss due to non-ideal cut surfaces, which are often caused by the deformation of the cut surface when using traditional cutting methods, where the cutting blade deeply cuts into the fiber.
Innovation Solution
A cutting device and method that utilize a resilient supporting piece with a cutting blade angled at a right angle to the optical fiber, applying tension and pressing the supporting piece in a direction perpendicular to the fiber's direction, allowing the cutting blade to make contact and rotate around the fiber's periphery, minimizing deep cutting and promoting a flat cut surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the cutting blade deeply cuts into the optical fiber, then the cutting force is sufficient to separate the fiber, but the cut surface deforms and deviates from an ideal plane surface
Solution Approach 1:
The resilient supporting piece is pre-configured to provide cushioning support to the cutting blade. When the blade contacts the optical fiber, the resilient supporting piece absorbs excess cutting force through elastic deformation, preventing the blade from deeply penetrating and deforming the cut surface while still allowing sufficient force for fiber separation.
Solution Approach 2:
The invention changes the mechanical parameter of the supporting structure from rigid to resilient. By using a resilient supporting piece with elastic properties, the system can dynamically adjust the cutting force applied by the blade, maintaining optimal cutting pressure without excessive penetration that would deform the cut surface.
2Ease of manufacture
If the cut surface is not an ideal plane surface perpendicular to the fiber direction, then the cutting process is simpler, but light scatters at the cut surface causing optical loss
Solution Approach 1:
The resilient supporting piece provides pre-configured cushioning that maintains consistent, controlled pressure on the cutting blade throughout the cutting process. This ensures the blade creates a clean, perpendicular cut surface without deviation, minimizing light scattering and optical loss while keeping the cutting process simple.
Solution Approach 2:
The invention replaces a rigid mechanical supporting system with a resilient elastic system. This substitution allows the cutting mechanism to automatically self-regulate the cutting force and maintain precise blade positioning, achieving ideal cut surfaces without complex control mechanisms.

AI summary
A cutting device for cutting an optical fiber running in a first direction includes a supporting piece having a free end and a fixed end and having resilience, a cutting blade supported by the supporting piece that comes into contact with the optical fiber to make a right angle with the optical fiber at a point of the contact, and a driving device. The driving device is configured to press the supporting piece in a second direction in a plane perpendicular to the first direction, with the second direction not intersecting with the first direction.
