Buoyant Fish Tail Fin for Stable, Realistic Lure Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fishing lures, particularly larger ones, face issues with unrealistic fish-like movement, excessive wiggle or oscillation, and high water resistance, which can fatigue the fishing line and rod, and require heavy weights to stabilize the hook, leading to increased drag and weight on the fisherman.
Innovation Solution
A fish tail fin connectable to a trailing hook, designed with buoyancy and a stabilizing shape to provide a realistic swimming motion, reducing oscillation and drag, and allowing for larger hooks and lighter equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a skirt is attached to or dragged behind a lure body, then the lure can replicate life-like swimming movements, but the skirt exhibits excessive wiggle or oscillation when dragged through water
Solution Approach 1:
The patent uses a flexible skirt made of thin film material that can move naturally in water to replicate fish-like swimming motions. The flexibility of the thin film allows it to undulate and wiggle in a realistic manner while still providing stable hook positioning through proper attachment design.
2Stability of the object's composition
If weight is added to the lure, skirt, or trailing hook to resolve excessive wiggle or oscillation, then the hook stability improves, but the drag and weight on the fishing line and fisherman increases
Solution Approach 1:
The patent employs a buoyant body that provides upward buoyant force to counterbalance the downward weight of the hook and skirt assembly. This counterweight principle allows the hook to maintain stable positioning without requiring additional stabilizing weights, as the buoyant body naturally offsets the gravitational pull on the trailing components.
3Reliability
If the hook is made bigger to increase fishing effectiveness, then the hooking probability improves, but the excessive wiggle or oscillation and rotation problems worsen
Solution Approach 1:
The patent introduces a buoyant body as an intermediary element between the lure and the hook. This intermediary component stabilizes the hook's orientation and reduces excessive wagging through its buoyant properties, allowing larger hooks to be used effectively without the stability problems that would otherwise accompany increased hook size.
4Shape
If jointed fishing lures are used to replicate natural S-shaped swimming action, then the swimming movement realism improves, but the design complexity and size increase
Solution Approach 1:
The patent uses a flexible skirt attached to the lure body that naturally undulates and wiggles in water to create realistic fish-like swimming motions. This flexible film approach achieves complex natural movements without requiring multiple jointed segments, thereby reducing structural complexity while maintaining movement realism.
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 fish tail fin stabilizes the hook, reduces drag, and enables more realistic fish-like movement, enabling the use of larger hooks and lighter fishing gear, while maintaining hook stability and reducing fatigue.
Implementation Method 1
the fish tail fin is configured to have a buoyancy to counter a weight of the hook
Implementation Method 2
reducing the drag and weight on the fishing line and on the fisherman
