Lines TRIZ Cases

A concealed latching hook nested inside a coil keeps fishing lines and leaders from snagging, cutting, or accidentally opening the snap.

Water-driven angled boards create predictable lateral force to keep multiple trolling lines separated despite boat or current direction changes.

A winding dial and ratcheting lock secure fishing line without knots, enabling quick lure changes and tool-free release.

A monolithic connector with a helical securing feature speeds leader changes while reducing knot tying and connector complexity.

A split fishing line fixture lets a UAV drop the hooked line while tracking fish, preventing the aircraft from being pulled into the sea.

A split bobber and snap-on bead let anglers attach or remove terminal tackle without cutting the fishing line, improving reuse and convenience.

A reciprocating line clip adds jerking motion and variable lure speed to downrigger trolling while allowing easy retrieval and less entanglement.

An inline float and bead-tensioned side leader stabilize the rig, cut drag and twisting, and reduce snagging across fishing methods.

Pseudorandom 30-50 kHz pings and fish-triggered activation deter larger toothed whales while limiting battery load and marine noise.

Two injection-molded stem parts and a compressible spring let one fishing bobber switch between fixed and slip modes.

A preloaded spring releases an immediate pull when a fish takes the hook, reducing delayed, skill-dependent manual striking.

A flexible wall with lugs and a zipper contains unspooled fly line, reducing tangles while allowing bucket disassembly for transport.

Multiple resistance points secure the lure against detachment while a retaining loop preserves natural movement.

A pivotable clevis and slotted opening accommodate angular variation, reducing strain, wear, corrosion, and damage in outrigger mounts.

This case integrates horizontal and vertical outrigger pivots, spline-based actuation, and handle-operated locking in a compact mount.

An internal male-female friction lock enables quick float adjustment while reducing line distortion and simplifying fishing-line attachment.

A pressure-sensing planer board remotely releases the fishing line after a strike, reducing tangles and simplifying retrieval.

Rim voids disrupt water flow to prevent over-rotation, ensuring consistent wobbling motion across various bait styles and weights.

A programmable electronic jigging device uses a microcontroller and servo motor to drive precise fishing rod movements.

A mechanical connector joins fishing lines using a cinch mechanism that eliminates time-consuming knot tying while preserving line strength.

A hook line attachment device uses a rotating proximal portion and spacer to secure lines without knots.

Intermediary shield extracts line from turbulent wake zone, maintaining lure stability and preventing debris entanglement at high speeds.

Segmented shaft and dynamic slide members enable versatile knot tying while preventing line damage from kinking.

A lure strike indicator assembly uses a sliding coupler and fastener to secure the indicator relative to the fishing line.

An ice fishing apparatus converts wind energy into automated jigging motion using an air foil and spring mechanism, eliminating manual operation.

A twist clip uses a rotating clamp head and core pin to securely retain fishing lines.

A strike indicator attachment tool cinches securing sleeves over fishing lines to position yarn indicators without damaging the leader.

A tip-up cover with a transparent lid lets anglers adjust lines without removal, while an aerator prevents ice holes from freezing shut.

Angular scale device measures fishing line orientation relative to the horizon, replacing trial-and-error dive charting with trigonometric precision.

Tapered anterior section produces laminar flow while flared posterior generates turbulence for lure presentation.

An asymmetric container design resolves the contradiction between ease of filling and secure closure by using a large main part as a scoop.

Segmented slots accommodate varying hook sizes while extraction of spring clips prevents saltwater corrosion and line crimping during knot formation.

A programmable trolley assembly adjusts draw ratios within heated media to produce tapered fishing lines with minimal transitional distances.

Pivotable base supports fishing rod butt while user stands on device to distribute weight and reduce abdominal strain.

A dual tripping system with independent force adjustment prevents premature release while a deformable sleeve minimizes line contact to reduce breakage.

A planer board integrates single and dual release actuators to manage gripping and guiding assemblies for fishing line attachment.

A drone fishing system uses a tether line management system with load cells and altimeters to maintain constant tension on multiple lines.

Threaded connector halves replace manual knot tying to resolve accessibility issues for anglers with limited dexterity.

Dynamic rudder plate adjusts to boat turbulence, maintaining structural integrity while deploying lures outside the wake.

Rotating secondary coupling components obstruct gaps to secure accessories, preventing line kinking during adjustment.

Segmented stem guides with intermediary springs prevent fishing line damage from sharp edges while enabling quick cartridge replacement.
