Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical fiber holding devices face challenges in applying consistent tension to optical fibers during cutting, as they require precise torque wrench adjustments to avoid damaging the fibers, and the operability is low due to the need for screwing and unscrewing the holders.
Innovation Solution
An optical fiber holding device with a holder comprising a base and a lid that are openable and closable, equipped with an elastic body, a drive unit, and a pusher that generates a pressing force to automatically sandwich the optical fiber, eliminating the need for precise torque wrench adjustments and improving operability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base and lid are tightly fixed using a screw, then the optical fiber is protected from slipping, but the optical fiber is destroyed due to excessive pressing force
Solution Approach 1:
The patent changes the parameter of pressing force from a fixed high value (screw fixation) to a controlled low value (elastic body deformation). The elastic body deforms under a predetermined small pressing force to fix the optical fiber, preventing both slipping and fiber damage. This parameter change resolves the contradiction by finding an optimal pressing force that ensures fixation reliability without causing fiber damage.
Solution Approach 2:
The elastic body acts as an intermediary between the lid and the optical fiber. Instead of directly pressing the optical fiber with high force, the elastic body mediates the force transmission, providing a cushioning effect that maintains appropriate pressing force for fixation while preventing excessive force from damaging the fiber.
2Object-affected harmful factors
If a torque wrench is used to fix the base and lid with high accuracy, then the optical fiber is protected from damage, but the operability is reduced due to the complexity of precise adjustment and screwing/unscrewing operations
Solution Approach 1:
The elastic body provides self-regulating pressing force through its deformation characteristics. The system automatically maintains the appropriate pressing force without requiring external torque wrench adjustment or complex operational procedures. This self-service mechanism eliminates the need for skilled operation while protecting the optical fiber from damage.
Solution Approach 2:
The patent replaces the complex mechanical screw fixation system requiring torque wrenches with a simpler elastic body deformation mechanism. This substitution eliminates the need for precise mechanical adjustment and skilled operation, significantly improving operability while maintaining fiber protection.
3Object-affected harmful factors
If the base and lid are not tightly fixed, then the optical fiber is protected from damage, but the optical fiber slips between the base and lid when pulled, preventing required tension from being applied
Solution Approach 1:
The patent optimizes the pressing force parameter to a predetermined low value that is sufficient to prevent fiber slipping during tensioning operations but low enough to avoid fiber damage. This parameter optimization resolves the contradiction by finding the optimal point where fixation reliability is achieved without causing harmful effects.

AI summary
An optical fiber holding device of the invention includes a holder that includes a base and a lid which are openable and closable, sandwiches an optical fiber when the base and the lid are in a closed state, and thereby holds the optical fiber. The holder includes: an elastic body; a drive unit configured to generate driving power; and a pusher. The pusher is configured to generate a pressing force based on the driving power generated by the drive unit and press the lid by the pressing force via the elastic body. The lid and the base are configured to sandwich and hold the optical fiber based on the pressing force transmitted through the elastic body when the lid is pressed by the pusher via the elastic body.
