Fishing Reel Stopper Mechanism with Biasing Hook and Collar
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fishing reel stopper mechanisms cause damage to fishing lines by subjecting them to sudden loads, twisting, and abrasion when locking and releasing, making it difficult to accurately control line length and prevent deformation.
Innovation Solution
A fishing reel with a movable hook and collar mechanism on the spool's outer surface, biased in the opposite direction of line release, which moves integrally with the fishing line to absorb load and prevent contact with the spool's surface, using a cylindrical tube and semicircular engagement part to retain the line without scratching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional stopper member is used to lock the fishing line, then the fishing line can be stopped at a desired position, but the fishing line is subjected to sudden load causing it to stretch, twist and degrade
Solution Approach 1:
The patent introduces a cushioning member (elastic body) between the stopper member and the fishing line that absorbs sudden loads before they reach the line. This cushioning element deforms elastically when the line is stopped, preventing shock transmission and line damage while maintaining accurate positioning capability
Solution Approach 2:
The cushioning member acts as an intermediary element between the rigid stopper mechanism and the fishing line. It mediates the interaction by providing a compliant interface that protects the line from direct contact with hard surfaces and sudden force application
2Ease of operation
If the fishing line is repeatedly released and locked by the stopper mechanism, then the line length can be controlled, but the fishing line is repeatedly pressurized and rubbed causing it to be twisted, scratched or deformed
Solution Approach 1:
The cushioning member is positioned to prevent direct contact between the fishing line and the hard spool surface or stopper edges during repeated locking operations. It absorbs rubbing forces and prevents abrasion that would occur with direct surface contact
Solution Approach 2:
The cushioning member is made of an elastic material that forms a flexible protective layer between the line and rigid components. This flexible element conforms to the line's movement while protecting it from mechanical damage during repeated operations
3Strength
If the locking part is formed of hard resin or metal for strength, then the stopper mechanism can lock the line firmly, but the fishing line contacts the locking part and spool edge causing it to be nipped and damaged
Solution Approach 1:
The cushioning member is introduced as an intermediary between the hard locking part and the fishing line. It allows the locking mechanism to maintain its strength and firm locking capability while preventing direct contact between the hard surfaces and the line, thereby eliminating nipping and contact damage
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents damage to the fishing line by distributing the load gently and reducing abrasion, allowing for precise control of line length and depth adjustment without line deformation.
Implementation Method 1
a biasing part configured to bias the hook and the collar in a direction opposite to a direction of releasing the fishing line... the hook and the collar are moved integrally with the fishing line in the direction of releasing the fishing line under a biasing force produced by the biasing part

AI summary
An object is to provide a fishing reel including a stopper mechanism (21) that prevents damage on a fishing line (15) and permits releasing a desired length of fishing line. In accordance with one aspect, a fishing reel has a hook (22a) and a collar (23) integrally provided on a spool (7) and configured to lock a fishing line therebetween. When the fishing line is released to the locked point, the hook (22a) and the collar (23) are moved integrally with the fishing line in the direction of releasing the fishing line, while receiving a biasing force that lowers the moving speed. In this movement, the fishing line does not contact the spool (7) and receives a relieved load.
