Optical Fiber Holder With Elastic Mediator for Tension Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical fiber holding devices face challenges in applying consistent tension to optical fibers during cutting, as tight fixation can damage the fiber, while loose fixation leads to slipping and inadequate tension, requiring precise torque wrench operation and low operability.
Innovation Solution
An optical fiber holding device with openable and closable holders, incorporating an elastic body, a drive unit, and a pusher to apply pressing force, allowing automatic closure and preventing fiber damage, along with a controller to determine optimal drive unit control based on fiber type and detection sensors for precise tension application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base and lid are tightly fixed using a screw, then the optical fiber is securely held, but the optical fiber is destroyed
Solution Approach 1:
The patent introduces an elastic body as an intermediary between the lid and the optical fiber. The elastic body deforms elastically under compression, providing a cushioning effect that prevents direct transmission of excessive force to the optical fiber. This mediator allows the lid to be tightly fixed while protecting the fiber from damage through elastic deformation rather than rigid contact.
2Object-affected harmful factors
If the degree of fixation is low, then the optical fiber is protected from damage, but the optical fiber slips between the base and lid, and required tension cannot be applied
Solution Approach 1:
The elastic body serves as a mediator that transmits force while accommodating deformation. It provides sufficient frictional force to prevent slipping when the optical fiber is inserted, while still allowing the lid to be fixed with enough force to maintain proper tension during cutting operations.
3Measurement precision
If a torque wrench with high accuracy is used to fix the base and lid, then the fixation precision is improved, but the operability is reduced due to the need for precise operation and screw release after cutting
Solution Approach 1:
The elastic body provides self-regulating force through its elastic properties. When the lid is closed, the elastic body automatically compresses and exerts a consistent restoring force that maintains proper fixation without requiring precise torque control. This self-service mechanism eliminates the need for torque wrenches and complex adjustment procedures, significantly improving operability while maintaining fixation precision.

Implementation Method 1
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

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.
