Horizontal Swingable Tail-Fin Fishing Lure Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fishing lures tend to jump out of the water when reeled in quickly, making it difficult to mimic the movement of fleeing fish and thus reducing the likelihood of attracting carnivorous fish like black bass.
Innovation Solution
A fishing lure design featuring a horizontally positioned tail-fin member that is freely swingable within a predetermined angle range, providing resistance to prevent the lure from jumping out of the water and creating a more realistic swimming motion, along with a link mechanism allowing the head and tail parts to swing freely, enhancing the lure's movement and attractiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the tail-fin member is provided in the up-down direction, then the fishing lure can be reeled up quickly, but the fishing lure jumps out of the water making it detectable by fish
Solution Approach 1:
The tail-fin member is repositioned from a vertical (up-down) orientation to a horizontal orientation relative to the fish-shaped body. This dimensional change allows the tail-fin to generate resistance in the horizontal plane, preventing the lure from jumping out of the water during fast reeling, while maintaining the ability to be reeled up quickly.
2Device complexity
If the tail-fin member is fixed rigidly, then the structure is simple, but the lure cannot create realistic swimming motion
Solution Approach 1:
The tail-fin member is designed to be freely swingable relative to the fish-shaped body within a predetermined angle range, transforming it from a static rigid component to a dynamic element. This allows the tail-fin to naturally oscillate and create realistic swimming motions that attract fish, while the swingable connection maintains structural simplicity.
3Force
If the tail-fin member extends far backward, then the resistance is increased preventing jumping, but the lure creates excessive drag
Solution Approach 1:
The tail-fin member is designed with optimized dimensions and an inclined configuration extending downward toward the rear. This parameter optimization provides sufficient horizontal resistance to prevent jumping out of water while minimizing excessive drag during reeling, achieving a balance between resistance force and energy loss.
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
The design effectively prevents the lure from jumping out of the water during rapid reeling, creating a convincing fleeing fish motion that attracts carnivorous fish, while minimizing user fatigue and allowing for two types of lure movements.
Implementation Method 1
the resistance of the tail-fin member prevents the fish-shaped body from jumping out of the water even when the user quickly moves the fishing lure by reeling up quickly
Implementation Method 2
The tail-fin member is attached so as to be freely swingable within a predetermined angle range relative to the fish-shaped body about a first axis extending in a front-rear direction
Implementation Method 3
a regulation part is preferably provided to at least one side of the attaching part, the regulation part regulating the swing movement of the tail-fin member about the first axis by abutting the rear end of the fish-shaped body

AI summary
A fishing lure includes a fish-shaped body in a shape of fish and a tail-fin member provided to a rear end of the fish-shaped body. An eye member to which a fishing line is tied is provided to a front end of the fish-shaped body. A lip member is provided at a front part of the fish-shaped body. The tail-fin member is horizontally provided to the fish-shaped body. It is preferable that the tail-fin member be attached to a rear end of the fish-shaped body so as to be freely swingable within a predetermined angle range about an axis extending in a front-rear direction.
