Shape Memory Alloy Artificial Bait for Natural Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fishing lures fail to accurately emulate the natural movements of insects and animals on the water's surface, such as bugs struggling, worms, frogs, or snakes, leading to unnatural presentations and reduced effectiveness in attracting fish.
Innovation Solution
The use of shape memory alloys (SMA) combined with motors, voice coils, and super capacitors to create realistic movements in artificial baits, allowing for the replication of natural motions like struggling insects or animals through controlled wing, tail, and body part movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traditional lures are pulled or jigged by the line to create motion, then the lure moves forward rapidly, but the motion becomes unnatural and creates harmful ripples on the water surface
Solution Approach 1:
The patent replaces the traditional mechanical line-pulling system with an internal actuation system using shape memory alloys (SMAs). The SMAs are heated electrically to change shape and move lure components internally, eliminating the need for external line manipulation. This substitution removes the harmful ripples caused by line contact while maintaining natural-looking motion.
Solution Approach 2:
The invention extracts the motion-generating function from the fishing line and relocates it inside the lure housing. By placing SMAs and heating elements within the lure, the system generates motion independently without requiring external line manipulation, thereby eliminating the harmful ripples and unnatural movement patterns.
2Device complexity
If traditional lures use simple mechanical structures, then the device complexity is low, but the ability to emulate natural movements of various creatures is limited
Solution Approach 1:
The patent implements a universal motion control system where a single SMA-based actuation mechanism can produce multiple different movement patterns. By controlling which SMAs are activated and how they are heated, the same lure can emulate the movements of insects, frogs, worms, or other creatures, providing multi-functionality without requiring separate mechanical systems for each creature type.
Solution Approach 2:
The invention uses dynamically controllable SMAs that can be heated to different temperatures and activated in different sequences to create varied movement patterns. This dynamic control allows the lure to adapt its motion characteristics in real-time, emulating different creatures and movement styles without changing the physical structure.
3Reliability
If shape memory alloys are used to create realistic movements, then the presentation to fish becomes more natural, but the power consumption increases
Solution Approach 1:
The patent employs periodic heating cycles of the SMAs rather than continuous heating. The SMAs are heated to trigger shape changes, then allowed to cool and return to their original shape, creating rhythmic movements that mimic natural creature behavior. This periodic action significantly reduces average power consumption compared to continuous operation.
Solution Approach 2:
The invention utilizes the phase transition properties of shape memory alloys, which change shape in response to temperature changes. By exploiting this inherent material property, the system achieves realistic movements through passive shape recovery after heating, rather than requiring continuous energy input to maintain the deformed state, thereby reducing overall power consumption.
