Solution Overview

Problem

Conventional electro-fishing devices struggle to create a strong and localized electrical field in environments with thick vegetation or obstructions, leading to insufficient stunning of small aquatic or semi-aquatic creatures and inefficient energy use.

Innovation Solution

An electroshock wand with a fixed, shorter distance between anode and cathode members at the electroshock end, creating a stronger, more localized electrical field that requires less energy and is consistent, allowing for effective stunning of targeted organisms at a distance from the operator.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If conventional electro-fishing devices use a large distance between anode and cathode, then the electrical field covers a larger area, but the field strength is insufficient and energy consumption increases

Engineering Contradiction:

Improvecoverage areaVSAvoidfield strength

Core Design Contradiction:

Area of stationary objectVSStrength

Solution Approach 1:

The patent applies local quality by concentrating the electrical field between closely spaced anode and cathode members at the electroshock end, creating a high-strength localized field for effective stunning, while the overall device maintains operational coverage through the extended wand structure

Inventive Principle:

Principle #3Local quality

2Power

If conventional devices use large anode-cathode distance, then more energy is required to create the field, but this leads to faster battery depletion and shorter runtime

Engineering Contradiction:

Improvefield generation capabilityVSAvoidenergy consumption

Core Design Contradiction:

PowerVSUse of energy by moving object

Solution Approach 1:

The patent changes the critical parameter of anode-cathode distance from large to short (fixed at 0.5 to 2 inches), which fundamentally alters the electrical field characteristics to require less energy while maintaining effective field strength for stunning aquatic creatures

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If conventional devices are used in thick vegetation or obstructions, then the electrical field is weakened and dispersed, but this results in insufficient stunning of small aquatic creatures

Engineering Contradiction:

Improveenvironmental adaptabilityVSAvoidstunning effectiveness

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The closely spaced anode and cathode members create a highly concentrated electrical field that maintains its strength through vegetation and obstructions, ensuring reliable stunning effectiveness in challenging environmental conditions where conventional devices fail

Inventive Principle:

Principle #3Local quality

4Ease of operation

If conventional devices are used, then energy must be constantly adjusted to compensate for varying distances, but this increases operational complexity and reduces consistency

Engineering Contradiction:

Improveoperational simplicityVSAvoidfield consistency

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The anode and cathode members are pre-positioned at a fixed short distance apart during manufacturing, eliminating the need for operational adjustments and ensuring consistent electrical field delivery without requiring user intervention or complex controls

Inventive Principle:

AI summary

An electroshock wand for safely and humanely stunning and capturing aquatic creatures is provided. The electroshock wand has a body, an anode member, and a cathode member. The anode and cathode members are attached at or near the electroshock end of the body, with the anode and cathode members being axially spaced from one another. The anode and cathode members create an intense and localized electrical field between one another that momentarily stuns a target organism. The target organism, once stunned may then be collected. This device offers a nonlethal method of capturing invasive species and removing them from specific environments.
