Fishing Nets TRIZ Cases
- Foldable Landing Net With Pivoting Support And Locking Pin
Pivoting net support parts lock via an elongate pin to resolve the contradiction between large capture area and transport complexity.
- Waterline Hatch Fish Transport Well
Separated shaft and vertical well minimize fish loss during hauling.
- Flasher Fish Attractor Parallel Blade Drag Reduction
Parallel blades on radial arms reduce drag while maintaining attractive motion for fish.
- Aquaculture Mortality Trap for Spar Buoy Fish Pens
Mortality trap on spar buoy captures sinking fish using a sloped transverse panel and one-way gate mechanism.
- Bendable Pet Waste Scooper with Corrugated Handle
A selectively bendable gripping tool uses a hollow corrugated extension to adjust jaw angle for sanitary waste collection.
- Copper Recovery from Waste Fishing Nets via Alkaline Washing and Electrolysis
Alkaline washing extracts copper compounds from waste fishing nets, enabling electrolytic recovery of pure metal while reducing disposal costs.
- UV-Reflective Fishing Lure Coating for Deep Water Attraction
A vinyl plastisol lure body reflects ultraviolet light to attract game fish at depths beyond three meters.
