Lines TRIZ Cases

Segmented buoyant members adjust water displacement via removable sections, resolving line damage from sharp saw cuts in hollow stems.

A programmable bobber uses a servo motor and armature to move fishing bait in vertical and horizontal directions.

A trotline canister uses a guide slot to sequentially engage swivels and prevent line entanglement during deployment.

Adjustable thumbscrew tightens ring grippers on fishing line to prevent tangling while maintaining consistent release force during kite fishing.

Braided synthetic polymer sheath surrounds a metal wire helix core to create flexible rig tubing for fishing lines.

A fishing line threading apparatus guides the line through a hook aperture using an integrated needle and seating chamber.

A knotless line attachment apparatus uses a compression spring to bias a collet, securing line ends through mechanical press fit.

A fishing lift accessory with outwardly extending wings secures to the leader line and elevates the rig above underwater debris.

A buoyant PVC foam card body integrates a pivoting swivel disc to simplify knot formation for anglers.

Segmented weights resolve retrieval entanglement by using near-neutral buoyancy to lift rigs above bottom obstructions.

Threaded male-female bases trap fishing lines to secure lures, eliminating knot-tying difficulties for users with limited dexterity.

A sensor-driven angling device pivots an arm to capture a fishing line automatically.

Optimized molecular weight and processing resolve the contradiction between mechanical strength and biodegradability in fishing nets.

A planar trolling device uses a line channel to enable independent control of fishing lure speed separate from watercraft movement.

A fishing protector device collects catch inside a tank via an opening mechanism and line guiding system.

Segmented rotating anchor wires reduce retrieval force by deflecting under tension, eliminating complex manufacturing processes for reusable designs.

Magnetic coupling components attach and detach fishing accessories quickly, preventing line damage while maintaining secure retention.

Angled connector with central groove secures fishing lines via friction, eliminating crimping tools while maintaining knot strength.

Segmenting the latch into a fixed dock and moving traveller resolves manual operation challenges at distant outrigger spars.

A cross-shaped spreader bar holds dodgers separately from the fishing line to maintain lure proximity.

A cylindrical knot tying apparatus uses a rotating channel to secure flexible lines and simplify the manual dexterity required for knot formation.

Through-holes in a spherical feed basket replace complex folding brackets, reducing device complexity while maintaining anchoring reliability.

Rotating swivel rings let outrigger line guides adjust their radial angle, reducing rigging line wear during vessel rocking motions.

A leader line spooling device winds and unwinds fishing line to change depth.

A variable displacement fishing device uses a spring mechanism to move bait into the fish's mouth, resolving tension issues that prevent secure hooking.

Worm gears provide torque to stabilize outriggers against wave forces, preventing uncontrolled rotation during high-speed operation.

A helical coil and expandable clamp join fishing line ends without manual knotting.

Spring-loaded shield arm deflects debris upwardly while the breakaway connector releases under force to prevent line damage.

A fishing line clip uses a friction grip clamp and oversized plug to secure lines on rods.

A winch-style inline fishing teaser reel integrates a two-handled drive for rapid retrieval of heavy dredges.

A monofilament leader uses a tapered intermediate section to balance casting weight with natural drift.

Circular tubular sleeves rotate freely around the main line to prevent separation under radial loads while reducing friction and abrasion.

A feeder connector uses elastic material to cushion hook loads while allowing quick reel line attachment.

Segmented stem guides enable damage-free cartridge replacement while cuttable buoyant members adjust floatation to counter tackle weight.

A magnetic slip bobber system locks onto a fishing line using an aperture magnet and line-stop to set the desired depth.

Radially offset cavity blocks swivel movement to stop leg breakage during casting.

A planer board uses a multi-point line guide system to flip onto its side for faster retrieval.

Movable fastening elements secure fishing lines in grooves, eliminating time-consuming knot tying and cutting for rapid attachment.
