Inertially-Activated Pivotable Hook Fishing Lure with Tone Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fishing lures are ineffective in attracting fish due to their reliance on visual and high-frequency sound stimuli, which are muted in murky water, and fail to produce lower frequency sound waves that fish are also attracted to.
Innovation Solution
A fishing lure with a mechanically-actuated tone generation device that produces lower frequency tones, optionally combined with higher frequency tones, using a striker and springs to create sound waves, and an inertially-activated pivotable hook system for enhanced attraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fishing lures use visual and high-frequency sound stimuli, then they can attract fish in clear water, but they are ineffective in murky water where such stimuli are muted
Solution Approach 1:
The patent changes the frequency parameter of sound waves from high-frequency to lower-frequency range (approximately 20-200 Hz) to overcome the muting effect of murky water. Lower frequency sound waves penetrate murky water more effectively and are detected by fish lateral lines, resolving the contradiction between visual/high-frequency sound attraction and murky water interference.
Solution Approach 2:
The patent replaces visual and high-frequency acoustic stimulation with mechanically-generated lower-frequency sound waves that physically vibrate through the water medium. This mechanical substitution allows fish to detect the lure through their lateral line system, which is sensitive to low-frequency vibrations, thereby overcoming the limitations of visual and high-frequency sound methods in murky conditions.
2Reliability
If fishing lures produce only high frequency tones, then they can generate audible sound, but they fail to produce lower frequency sound waves that fish are also attracted to
Solution Approach 1:
The patent expands the frequency parameter range from exclusively high-frequency to include lower-frequency sound waves (approximately 20-200 Hz). By using mechanical actuation methods such as oscillating weights or vibrating elements, the system generates lower frequency tones that resonate with fish lateral line sensitivity, thereby increasing adaptability to different fish species and environmental conditions.
Solution Approach 2:
The patent makes the sound generation system multi-functional by producing both high-frequency and lower-frequency tones simultaneously or alternately. This allows the lure to appeal to different fish species with different frequency preferences and to adapt to various water conditions, enhancing overall versatility and effectiveness.
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 attracts fish by producing audible sound waves in murky water and increases the chances of hooking with the pivotable hook system, improving fish attraction and catch rates.
Implementation Method 1
a tone generation device which produces one or more lower frequency tones alone... the tone generation device includes a tone generator (e.g., one or more springs, or tension elements arranged to vibrate upon actuation) and a striker that periodically strikes the tone generator and actuates the tone generation device
Implementation Method 2
fish have a nerve system that is stimulated or activated by their lateral line response signals. The fish senses and picks up sound waves and high and low frequency vibrations by their lateral line... water provides an excellent medium for the transmission of sound waves
Implementation Method 3
an inertially-activated pivotable hook system having a pivotable hook assembly... the pivotable hook system further comprises a biasing element arranged to bias the pivotable hook assembly towards the retracted position
