Segmented Fishing Lure With Restricted Swing for Natural Action
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fishing lures are limited in their ability to attract fish by generating bubbles or sounds and do not effectively mimic natural fish movements to adapt to different fishing conditions, such as tide and current.
Innovation Solution
A lure design featuring a first body with a shaft and a second body that swings relative to the first body within a restricted range, using a restricting structure to create varied attractive actions by altering light reflection and vibration frequency, and incorporating multiple bodies to enhance movement complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the second body is allowed to rotate fully (360°) around the shaft, then the lure can generate continuous movement, but it cannot create the phase difference and varied attractive actions needed to attract different types of fish
Solution Approach 1:
The lure body is divided into a first body and a second body that can swing independently relative to each other around the shaft. This segmentation allows the second body to move in a phase different from the first body, creating varied attractive actions without requiring a complex control system.
Solution Approach 2:
The second body is designed to swing dynamically within a restricted angle range rather than rotating fully. The restricting structure (protrusion and recess) provides dynamic constraint that allows movement within desired limits while preventing over-rotation, enabling natural-looking fish movement patterns.
2Adaptability or versatility
If the lure simply floats on water, then it is easy to manufacture and operate, but it cannot effectively blend with currents or mimic natural fish movements to attract predatory fish
Solution Approach 1:
The lure incorporates a dynamic swinging mechanism where the second body swings relative to the first body within a restricted angle. This creates natural movement patterns that mimic real fish behavior in currents, allowing the lure to blend with water flow while maintaining operational simplicity.
Solution Approach 2:
The swinging second body generates mechanical vibrations and movements that replicate natural fish behavior in current. This vibration and movement pattern makes the lure more attractive to predatory fish while maintaining ease of operation through passive water-driven motion.
3Adaptability or versatility
If conventional lures generate only bubbles or sounds, then the structure is simple, but they cannot provide varied attractive actions suitable for different fish types
Solution Approach 1:
The lure structure is segmented into multiple bodies (first body and second body) that can move independently. This segmentation enables varied attractive actions including light reflection changes, vibration frequency variations, and bubble generation, providing versatility for different fish types without excessive complexity.
Solution Approach 2:
Different parts of the lure have specialized functions: the first body provides stable mounting and basic buoyancy, while the second body provides dynamic movement and attraction. This local quality differentiation enables varied attractive actions while keeping each component relatively simple in design.
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 lure achieves enhanced fish attraction by mimicking natural fish movements, blending with currents, and generating bubbles and sounds, providing a variety of attractive actions suitable for different fish types.
Implementation Method 1
a second body (10B) that is supported around the shaft (20) so as to be able to swing, and a restricting structure (30) that is provided on at least one of the second body (10B) and the shaft (20) and restricts a swing angle of the second body (10B)
Implementation Method 2
Conventional lures, such as those shown in Japanese Laid Open Patent Application No. Hei 9 (1997)-266737 and 2011-87533), are limited to generating bubbles or sounds in water in order to attract fish.
Implementation Method 3
Conventional lures, such as those shown in Japanese Laid Open Patent Application No. Hei 9 (1997)-266737 and 2011-87533), are limited to generating bubbles or sounds in water in order to attract fish.
Implementation Method 4
The second body that is separate from the first body swings in a phase different from that of the first body, causing the second body to move differently from the first body
Implementation Method 5
when the lure is subjected to swash, waves, or the tide, the first body moves differently than the second body in an efficient manner. As a result, it is possible to move the lure so as to blend with the current

AI summary
A lure includes a head body, a swinging shaft, a truck body and a restricting structure. The swinging shaft extends from the head body toward a tail side. The trunk body is supported around the swinging shaft so as to be capable of swinging. The restricting structure is provided on the trunk body and the swinging shaft. The restricting structure restricts the swing angle of the trunk body. The swinging shaft is fixed to the head body.
