Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aquaculture methods face challenges in efficiently guiding and managing aquatic organisms, particularly in fish farming, due to the need for manual intervention, which is labor-intensive and risky, and often results in suboptimal productivity due to weather conditions and accessibility issues.
Innovation Solution
A system utilizing electrode units in water to generate electric and magnetic fields, allowing for the stimulation and guidance of aquatic organisms without direct contact, enabling automated movement and positioning of fish through controlled electric pulses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual work is performed to guide and manage aquatic organisms, then direct control over fish movement is achieved, but labor intensity and risk increase significantly
Solution Approach 1:
The patent replaces manual mechanical operations with an electrical stimulation system. Electrode units generate electric fields that stimulate aquatic organisms to move voluntarily, eliminating the need for physical handling by workers. This substitution of mechanical/manual systems with electrical fields directly resolves the contradiction by maintaining control capability while eliminating labor intensity and associated risks.
Solution Approach 2:
The system enables aquatic organisms to move themselves in response to electrical stimulation, rather than being physically moved by human workers. The organisms' own movement mechanisms are utilized through voluntary response to electric fields, reducing the need for external mechanical intervention and improving labor efficiency while maintaining operational control.
2Ease of operation
If workers access fish preserves by ship to perform tasks, then direct intervention is possible, but safety risks and operational limitations increase
Solution Approach 1:
The patent replaces the mechanical system of ship-based worker access with an electrical field-based remote control system. Electrode units deployed in the water can be controlled from shore or nearby vessels, eliminating the need for workers to physically access fish preserves in harsh marine environments. This resolves the contradiction by maintaining direct intervention capability through remote electrical control while eliminating safety risks associated with ship-based operations.
3Ease of operation
If fish are physically handled for movement and management, then direct control is achieved, but fish quality and welfare deteriorate
Solution Approach 1:
The patent replaces mechanical physical handling with electrical field stimulation. Instead of using nets, hands, or other mechanical means to move and manage fish, the system uses electric fields to induce voluntary movement in the aquatic organisms. This eliminates physical contact that causes stress, injury, or quality deterioration, while maintaining effective control capability through the organisms' natural response to electrical stimulation.
4Device complexity
If electric fences are used to guide aquatic organisms, then physical barriers are eliminated, but the ability to guide organisms voluntarily is insufficient
Solution Approach 1:
The patent changes the fundamental parameter of interaction from passive physical barrier (electric fence) to active controlled stimulation (electrode units with controllable electric fields). By adjusting voltage, current, pulse duration, and electrode configuration, the system can guide organisms voluntarily through controlled stimulation rather than forcing them through physical barriers. This resolves the contradiction by eliminating complex physical barriers while achieving effective voluntary guidance through parameter-controlled electrical fields.
