Fishing Nets TRIZ Cases
- Directional Acoustic Emitters for Trawl Fish Guidance
Directional acoustic emitters emit angled sound to startle fish, creating virtual barriers that prevent escape from the towing trajectory.
- Lead-free Cu-Zn Alloy for Aquaculture Wire
A lead-free copper-zinc alloy composition enhances machinability and corrosion resistance for aquaculture wire production.
- Marine Specimen Capture System Using Induced Flow
Induced flow from thruster assemblies pulls marine specimens into capture inlets, preventing physical trauma during live retrieval.
- Telescopic Net Closure with Frictional Draw Stem
A telescopic net assembly uses a frictional draw stem to retract the handle and close the netting.
- Corkline Stacker Arm Integrated with Net Crane
A corkline stacker arm mounts directly on a net crane vertical arm to move in tandem with the net layer roller.
