Optical Parts TRIZ Cases
- Polysiloxane with Hydroxyl Side Chains for Ophthalmic Devices
Replacing ether bonds with stable hydroxyl groups eliminates degradation in phosphate buffer solutions while maintaining oxygen permeability.
- Multi-Focal Lens System Fluid Transfer Mechanism
A two-lens optical system changes focal length by transferring fluid between internal cavities within each lens element.
- Multi-layer Dielectric Spectral Filter for Circadian Light
Alternating high and low refractive index layers in a dielectric filter transmit 98-100% of 455-560 nm light while blocking other spectra.
- TTL Loupes Declination Angle via Carrier Lens Segmentation
Segmenting carrier lenses with holes allows ocular devices to extend below the bottom edge, increasing declination angle and reducing neck strain.
- Corneal-Scleral Orthokeratology Lens Centering
A corneal-scleral orthokeratology lens transfers centering responsibility to the limbal-scleral region using asymmetric blends.
- Configurable Grid Vision Correction via Magnetic Nanoparticles
A configurable grid alters light paths using magnetically sensitive nanoparticles to correct visual acuity directly on electronic displays.
- Phosphorylcholine-Coated Contact Lens Boronic Acid Attachment
Boronic acid linkages attach phosphorylcholine coatings to hydrogel lenses, eliminating organic solvents and reducing dimensional variations.
- Progressive Ophthalmic Lens Aberration Control
Segmented lens surfaces minimize optical aberrations and root mean square deviation to enhance visual acuity in distance vision.
- Hybrid Mineral-Organic Electrochromic Lens Structure
A hybrid mineral-organic electrochromic lens structure integrates a glass substrate with an organic polymer shell to form the optical device.
- Guest-Host Liquid Crystal Filter with Retarder
A guest-host liquid crystal filter uses a half-wave retarder to rotate polarization states between two crossed devices.
