Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optical fibers may suffer surface damage or twisting due to misalignment of guide roller bodies during the manufacturing process, which can lead to defects in the fiber's shape and quality.
Innovation Solution
A guide roller mechanism with a position adjustment mechanism and an angle adjustment mechanism to accurately align the guide roller bodies, ensuring precise alignment and preventing twist by using a distance sensor to measure and adjust the attachment positions of multiple guide roller bodies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If guide roller bodies are used to guide the optical fiber, then the optical fiber can be guided through the manufacturing process, but misalignment of the guide roller bodies causes surface damage or twisting of the optical fiber
Solution Approach 1:
The invention adjusts the positional parameters (coordinates) and rotational parameters (angles) of multiple guide roller bodies to achieve precise alignment. By changing these parameters systematically, the guide rollers are positioned exactly where needed to guide the optical fiber without contact-induced damage or twisting
Solution Approach 2:
The invention replaces manual or rough mechanical alignment methods with an automated measurement and adjustment system. A measurement device detects the actual positions of guide roller bodies, and this information feeds into an adjustment mechanism that automatically corrects misalignments, substituting precision mechanical control for less accurate mechanical positioning
2Shape
If a swing roller is used to twist the optical fiber to achieve a circular shape, then the optical fiber shape can be improved, but the additional mechanism increases device complexity
Solution Approach 1:
The guide roller bodies serve multiple functions: they guide the optical fiber through the manufacturing process, maintain proper fiber orientation, prevent twisting, and ensure accurate positioning for subsequent processing steps. This multi-functionality eliminates the need for separate swing rollers or twist-correction mechanisms
Solution Approach 2:
The invention extracts the essential function of shape control from the complex swing roller mechanism and integrates it into the basic guide roller positioning system. By properly positioning the guide rollers, the optical fiber naturally maintains its desired shape without requiring additional active twisting mechanisms
