Glass Making Apparatus TRIZ Cases
- Knotting Glass Fiber Roving Packages via Sequential Inner-Outer Fiber Connections
Sequential inner and outer fiber connections link glass fiber roving packages into continuous units for automated production.
- Optical Fiber Preform Core Rod D/d Ratio Increase
Stretched core rods enable direct soot overcladding, eliminating intermediate glass cylinders and reducing manufacturing costs by 15% to 30%.
- Capillary Array With Low Refractive Index Layer for Crosstalk Reduction
Low refractive index layers and absorption gaps eliminate crosstalk, boosting spatial resolution and coupling efficiency.
- Multi-core Optical Fiber Refractive Index Matching
A multi-core optical fiber design aligns effective refractive indices across cores to preserve measurement accuracy.
- Tapered Spot Size Converter for Optical Coupling Loss
An asymmetric tapered spot size converter reduces optical coupling loss by minimizing the full-width at half maximum of the far-field pattern.
- Flat-Cross-Section Glass Fiber Reduces Blade Abrasion
Flat-cross-section glass fibers with controlled irregular shape ratios and packing rates enhance chopped strand productivity.
- Optical Fiber Dopant Profiles for Brillouin Scattering Peak Separation
Stepwise dopant profiles in optical fiber cores enhance fundamental mode interaction with acoustic modes to increase Brillouin scattering peak intensity.
- Optical Fiber Cooling and Coating with CO2 Sealing
Carbon dioxide gas seals the cooling flow channel to prevent helium dilution, reducing manufacturing costs while maintaining consistent coating thickness.
- Digital Camera Measurement for Large Optical Preforms
A digital camera system measures large optical preform diameters through a lateral furnace opening, overcoming laser scanning limitations.
- Optical Fiber Preform with Alkali Metal and Oxygen Doping
Precise alkali metal and oxygen concentration control in silica-based cores lowers attenuation while shortening doping process time.
- Disposable Fiber Filter for Tailing Pond Remediation
Disposable fiber filters recycle contaminated fluids from tailing ponds by replacing complex maintenance with low-cost, single-use cartridges.
- Single-mode Optical Fiber with Depressed Claddings
Multiple depressed claddings in a single-mode optical fiber reduce attenuation and leakage losses, avoiding complex fluorine-doping processes.
- Ultra-low-loss optical fiber supercooling method
Rapidly cooling the fiber during drawing lowers fictive temperature to reduce Rayleigh scattering loss while maintaining high productivity.
- Covered Base Material Gripper for Porous Glass Preform Production
Clean air convection inside a protective cover shields the rotating base material gripper from hydrogen chloride corrosion, maintaining preform quality.
