Rotatable Fin Fishing Lure with U-Shaped Pivot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing artificial fishing lures lack effective movement simulation of a fish in water, particularly during ice fishing or still fishing, as their lateral fins are fixed and do not mimic the natural swimming motion of a fish.
Innovation Solution
A fishing lure with a streamlined elongated body and movable lateral fins, utilizing a U-shaped member with a base and parallel fins that rotate up and down, simulating a fish's movement by limiting their range of motion within a cavity, allowing for forward motion when submerged and raised.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If lateral fins are made fixed on the lure body, then the structure is simple and stable, but the lure cannot simulate natural fish swimming motion
Solution Approach 1:
The patent transforms the fixed lateral fins into movable fins that can rotate up and down relative to the lure body. The fins are mounted on a pivot axis and can move through a limited range of motion, allowing them to simulate natural fish swimming movements while maintaining structural stability through the pivot mechanism and limiting lugs.
2Ease of manufacture
If lateral fins are made movable to simulate fish motion, then the lure attracts fish better, but the structure becomes more complex
Solution Approach 1:
The patent divides the fin assembly into separate components: the fin itself, the pivot axis, the lugs for limiting motion, and the cavity for receiving the U-shaped member. This segmentation allows each component to be manufactured independently and assembled together, reducing overall structural complexity while enabling realistic fish-like movement simulation.
3Ease of manufacture
If fins are allowed to move freely, then the swimming motion is more natural, but the fins cannot maintain proper orientation and position
Solution Approach 1:
The patent implements a dynamically constrained fin system where the fins can move within a predetermined range of motion defined by upper and lower limits. The cavity structure with its first and second portions, along with the lugs, provides dynamic constraints that allow natural swimming motion while maintaining proper fin orientation and position throughout the movement cycle.
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 effectively simulates a swimming fish, attracting fish with its natural motion, increasing the chances of catching, and is designed for use in both ice fishing and open water conditions.
Implementation Method 1
the two parallel fins importing forward motion to the lure by the trailing edge moving upward relative to the leading edge when the lure is lowered in the water and moving downward relative to the leading edge when the lure is raised in the water

AI summary
An artificial fishing lure has a stream-lined elongated body generally simulating a fish. The body has a cavity therein to receive a U-shaped member that is oriented to have two substantially parallel fins extending rearward outside of the body. The U-shaped member has a base and tab extending therefrom. The cavity is shaped to limit movement of the U-shaped member in an up and down rotational motion relative to the body. The body is formed from an upper body and a lower body. The U-shaped member is inserted into the cavity and the upper body and lower body are then affixed to one another. A method of constructing the lure is described.
