Fishing TRIZ Cases
- Crab Pot Tunnel Gate With Trigger Bars to Prevent Egress
Pivoting trigger bars and a flat tunnel floor let crabs enter more easily while restricting escape from the pot.
- Ropeless Fishing Gear Buoyancy Release for Reliable Trap Retrieval
A piston-based buoyancy changer replaces fuse-dependent release, improving trap retrieval reliability while removing ropes that entangle marine life.
- Spear Fishing Hand Strap for One-Handed Loading and Aiming
A muzzle-mounted hand strap secures the spear without locks or triggers, improving one-handed underwater control, range, and accuracy.
- Acoustic Shark Repellent With Removable Orca-Sound Mounting
Simulated orca hunting sounds and a removable mount let this underwater repellent deter sharks on surfboards, kayaks, or wearable gear.
- Lobster Trap Drawstring Mesh for Faster Catch Unloading
A drawstring mesh opening speeds lobster trap unloading, using elastic release and gravity-guided discharge to cut handling time.
- Scallop Trap Gateway with Movable Arms for Selective Entry
A sloped passageway and independently movable arms help scallops slide into traps while limiting entry by larger crustaceans.
- Urchin Culling Mechanism with Real-Time Seafloor Monitoring
A buoy-linked underwater mechanism attracts and culls sea urchins while computer vision tracks density and biodiversity continuously.
- River-Bottom Intercepting Net with Lead-Core Anchoring for Reversing Currents
This case uses segmented lead-core ropes and anti-escape net portions to stabilize interception under reversing river currents.
- Crab Trap Marine Counter with Radio Beacon
A marine counter detects crab entries and triggers a floatable beacon to surface.
- Aquatic Animal Trap with Feeding Tray for Predator Removal
A flexible tube connects an aquatic animal trap to an open feeding tray, allowing harmful species to walk toward natural predators.
- Detachable Spearfishing Barb With Pivoting Retention
Segmented barb pivots on impact to protect the shaft while tethering fish for reliable retention.
- Automated Bait Fish Trap with Light Lure and Capacity Alert
An automated bait fish trap replaces manual wading with a light lure and capacity indicator, eliminating labor risks while ensuring efficient capture.
- Deep-Sea Suction Sampler With Pressure Compensation And Semiconductor Cooling
Semiconductor refrigeration maintains in situ temperature while pressure compensation preserves depth pressure, preventing larval death during collection.
- Extendable Fish Pot with Buoyant Frame for Deck Space
Floating elements extend the frame structure when submerged, resolving the conflict between high fishing capacity and limited deck storage space.
- Multi-Branch Net Box Trap for Efficient Fish Catching
Symmetric multi-branch design eliminates stiffening structures, reducing fish injury and installation labor while maintaining high catch rates.
- Collapsible Fish Trap with Acoustic Masking
A collapsible fish trap uses acoustic masking to evade whale predation while maintaining structural integrity for small-vessel fishing operations.
- Aquatic Trap Nested Stacking Tapered Frame Design
Tapered aquatic trap frames allow nested stacking, reducing deployment trips and labor intensity.
