Fish Attraction Device Using Cupped Paddle Impeller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fishing technologies face challenges in effectively attracting fish due to limitations in simulating natural feeding activities, particularly for novice fishermen, as existing lures and electronic devices may not convincingly mimic the sensory inputs that attract fish, leading to uncertainty in locating and catching fish.
Innovation Solution
A fish attraction apparatus featuring a motor-driven impeller with flat planar blades and cupped paddles that generates turbulence and cavitation in water, producing visual and audible effects simulating fish feeding activity, thereby attracting schooling fish like striped bass.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional lures are used to attract fish, then the device complexity remains low, but the effectiveness in simulating natural feeding activity is insufficient
Solution Approach 1:
The patent combines multiple attraction mechanisms into a single integrated device: mechanical impeller for water agitation, electronic speaker for sound emission, and LED lights for visual attraction. This merging of functions resolves the contradiction by achieving superior fish attraction effectiveness while consolidating complexity into one unified system rather than requiring multiple separate devices.
Solution Approach 2:
The fishing device performs multiple functions simultaneously: it agitates water to create visual disturbances, emits electronic sounds to attract fish, and provides illumination. This multi-functionality allows the single device to effectively attract fish through multiple sensory channels, resolving the limitation of traditional single-function lures without requiring multiple separate devices.
2Measurement precision
If electronic visualizers with sonar are used to locate fish, then the measurement precision of fish position improves, but the device cannot actively attract fish when the fisherman is immobile or out of range
Solution Approach 1:
The device acts as an intermediary between the fisherman and the fish. It extends the fisherman's reach by actively attracting fish to the device's location through mechanical and electronic means, allowing the fisherman to remain stationary or positioned outside traditional casting range while still effectively attracting and catching fish.
3Reliability
If electronic callers emitting simulated sounds are used, then the auditory attraction capability is enhanced, but the simulation may not be convincing enough to fool fish
Solution Approach 1:
The patent merges electronic sound emission with mechanical water agitation and visual LED illumination. This combination creates a multi-sensory attraction system where sounds are accompanied by actual water disturbances and light effects, making the simulation more convincing to fish by engaging multiple sensory channels simultaneously rather than relying on sound alone.
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 apparatus effectively attracts fish by creating rhythmic sound and visual effects that mimic feeding activity, increasing the chances of catching fish, particularly in conditions that correlate with typical feeding behaviors of targeted species.
Implementation Method 1
The cupped paddle may generate turbulence and cavitation upon alternatingly entering and exiting the body of water as the impeller is rotated by the motor
Implementation Method 2
The cupped paddle may generate turbulence and cavitation upon alternatingly entering and exiting the body of water as the impeller is rotated by the motor
Data Source
AI summary
An apparatus for attracting fish is disclosed. The apparatus has a motor with rotating driveshaft that defines a rotational axis substantially parallel to a surface of a body of water. A housing encloses the motor, and the driveshaft extends therefrom. There is an impeller with a hub axially aligned with and coupled to the driveshaft. The impeller has one or more flat planar blades, each defined by a trailing edge and a leading edge and extending radially from the hub in an orthogonal relationship to the rotational axis of the driveshaft without pitch. A proximate end of the blades is fixed to the hub an opposed distal end includes a cupped paddle projecting therefrom with a paddle leading surface and a paddle trailing surface. Turbulence and cavitation is generated by the impeller, and the visual and audible side effects thereof are simulative of fish feeding activity.
