Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluorine-containing resin compositions used in plastic optical fibers (POFs) face challenges in reducing environmental impact and impurity intrusion during processing, with conventional solvents having high global warming potential and allowing significant elution of process materials.
Innovation Solution
A fluorine-containing resin composition using perfluoroalkene as the solvent, which has a lower global warming potential and does not elute process materials, combined with a fluorine-containing polymer structure that enhances solubility and filterability, reducing impurity intrusion and environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional solvents are used in fluorine-containing resin compositions, then the resin can be dissolved and processed, but the global warming potential increases and process materials elute into the composition
Solution Approach 1:
The patent changes the chemical parameters of the solvent from conventional fluorinated solvents to perfluoroalkenes, which have different molecular structures and properties. This parameter change results in lower environmental impact and reduced elution of process materials while maintaining the ability to dissolve fluorine-containing resins for optical fiber manufacturing
Solution Approach 2:
The perfluoroalkene solvent is designed to be used in a controlled manufacturing process where it can be easily removed or replaced after serving its purpose of dissolving the resin and enabling filtration, rather than remaining as a permanent component in the final optical fiber product
2Manufacturing precision
If filtration is performed to remove foreign matter from fluorine-containing resin, then optical quality improves, but process materials may be lost or contaminated
Solution Approach 1:
The perfluoroalkene solvent acts as an intermediary that enables effective filtration by dissolving the fluorine-containing resin and keeping it in solution during the filtration process. This allows foreign matter to be removed while the resin remains dissolved and can be recovered after filtration, minimizing material loss
Solution Approach 2:
The patent utilizes the specific solubility parameters of perfluoroalkenes to maintain resin in solution during filtration, changing the physical state and flow properties of the resin to enable effective separation of impurities while preventing resin deposition or loss in the filtration system
