Reels TRIZ Cases

A lever member switches between main and secondary drag modes, resolving fine-tuned control issues in live bait fishing.

A resilient gripping member adhered to a recessed base absorbs rod vibrations, reducing hand strain during extended fishing sessions.

A roller clutch uses a protrusion portion to regulate movement and resist spring bias.

A double bearing reel embeds the opening mechanism operation member within a cover plate side surface opening to maintain a smooth grip.

A bail flip mechanism uses a switch member with two slopes to move a moving member across a dead center for smooth bail arm return.

A spool brake unit analog-controls coil current via tension feedback to stabilize braking force on dual-bearing reels.

A fishing line clip uses a bulged portion to guide and retain lines on the spool.

A fishing reel shaft bearing with an adjustment portion moves the drive shaft axially to align gears.

A fishing reel uses an arcuate magnet to apply dynamic braking force that slows the spool, preventing line tangling and backlash.

Segmented cam features allow complex interface geometries while enabling easy cover removal by rotating the lock member independently.

Dynamic braking force adjustment prevents line backlash during deceleration while maintaining casting distance by adapting to varying spool speeds.

Segmented circumferential grooves with O-rings prevent magnetic fluid entry into one-way clutch while maintaining inner ring strength.

A motor operationally coupled to a fishing reel executes programmed motion profiles to drive the spool.

Relocating the drag mechanism to the rotor eliminates line twisting while maintaining instant engagement and precise pressure adjustment.

A fishing reel clutch mechanism uses a fixing plate to retain the handle shaft and guide kick members for reliable operation.

Segmented pinion shaft with intermediary support prevents friction-induced noise and casting distance loss during clutch-off operations.

A control case uses recess-projection fitting portions to align through holes in the upper case and cover member for accurate switch operation.

A dual-bearing reel uses a tapered lid outer surface to guide fishing line away from the structure.

A removable vinyl or metal cover seals the fishing reel end to hide surface scratches and maintain aesthetic integrity.

Engaging protrusions on the cover member prevent friction disk rotation while maintaining uniform gaps that reduce water ingress and fluctuating drag force.

Front-mounted clutch detection sensors reduce rear-end protrusion and improve casting balance.

A braking device adjusts spool rotation force via a control unit that monitors battery levels to maintain reliable operation.

Segmented cover openings and nested heat releasing members dissipate motor heat while preventing user contact and line entanglement.

Nested rotary members inside the handle prevent accidental changes while maintaining clear visibility of line specifications.

Elastic member between collar and nut accommodates misalignment, reducing frictional forces on the pinion gear.

Segmented knot hiding sections extract protruding knots from the winding path, eliminating casting interference and simplifying line connection for beginners.

Protrusions on the reel unit guard engage restriction portions on the chassis or lid member to prevent downward displacement and wobbling.

An intermediate member mediates screw fixation within a spinning reel body, preventing rear exposure of fasteners while maintaining structural integrity.

Segmented guard portions detach independently from the rotor body to resolve the contradiction between boundary protection and repair complexity.

A resin collar member stabilizes spool shaft sliding through controlled thermal expansion.

A magnetic braking device for fishing reels uses a reduction mechanism to apply force.

A dual-bearing reel uses a flat radial operating lever to adjust braking force on the outer ring.

Protrusion-aperture interfaces enable complete base extraction from the seed tube, eliminating trapped moisture and reducing mold contamination risks.

Segmented clamp and stopper components simplify setup and improve adaptability across various fishing reel types.

A fishing reel seal member uses a rigid shape-retaining portion to hold its form while an elastomeric layer provides waterproofing.

An enlarged gear housing opening paired with a gap filling portion enables easy gear maintenance while preserving seal integrity.

A dual-bearing reel uses a tubular pinion gear with outer and inner perimeter support to reduce structural flexing.

Nesting the support shaft inside the U-shaped spring reduces installation space, allowing balanced screw hole placement and improved body strength.
