Spectales/Goggles TRIZ Cases
- Curved Rotary Turning Insert for Low-Wear Freeform Machining
A continuously varying cutting-edge radius spreads load, cuts wear, and supports faster freeform turning on existing lathes.
- Ophthalmic Lens Laser Alignment for Automated Optical Feature Formation
Optical fiducial alignment automates laser formation of myopia-control lens features, improving precision and manufacturing throughput.
- Spectacle Lens Laser Marking on Low-Reflectance AR Coatings
Selecting the lower-reflectance AR-coated lens surface at 355 nm enables precise laser marking while limiting damage to underlying layers.
- Eyewear Frame Energy Dispersion Structure for Lens Retention
An overmolded impact-dispersing groove lets rigid eyewear frames flex under impact, absorb energy, and keep the lens in place.
- Slotted Eyeglass Screw With Friction Insert Against Loosening
A slotted screw with a neoprene or polypropene insert adds frictional drag to stop eyeglass lens screws from backing out.
- Dual-Receptacle Cutting Insert Holder for Longer Edge Life
Intersecting insert receptacles let one diamond cutting insert be repositioned to use a fresh edge area while maintaining tip height and micrometer precision.
- Ophthalmic Lens Edging Using Shared Frame Data and Local Corrections
A two-table frame database combines shared eyewear outline data with local corrections to improve lens edging accuracy and reduce setup effort.
- Composite Button Assembly for Watertight Overmolded Housings
A preformed button insert with a flexible membrane improves adhesion, simplifies molding on complex housings, and maintains a watertight seal.
- Spectacle Lens Hole Drilling Aligned to Pantoscopic Angle
A processor sets drilling angle from pantoscopic angle and lens position, enabling precise spectacle lens holes with simpler setup.
- Tool Drive Unit With Oscillating Transverse Motion Near Rotation Axis
Superposed transverse oscillation lets the cutting edge machine near the rotation axis without pin formation, surface damage, or slow small-radius cutting.
- Rotating Shaft Mechanism With Hollow Circuit Passage for Wearables
A hollow shaft region routes external circuits through the hinge, reducing damage risk while improving wearable reliability and appearance.
- Rimless Eyeglass Lens Mounting With a Shared Threaded Bore
A shared threaded bore in the lens and mounting protrusion enables flush rimless eyeglass assembly without custom-cut fasteners.
- Composite Button Membrane Assembly for Watertight Housing Sealing
A preformed membrane on a rigid frame is overmolded into the housing to improve adhesion compatibility, sealing, and tooling simplicity.
