Multi-floor Net Aquafarming System for Shellfish Cultivation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional seawater-based shellfish cultivation faces challenges in controlling water flow, temperature, sunlight exposure, salinity, and pollution, leading to low survival and harvest rates due to inadequate nutrient supply and bacterial contamination, while indoor aquafarming systems struggle with water purity and labor-intensive maintenance.
Innovation Solution
An indoor aquafarming system featuring a multi-floor net assembly with a stainless steel or reinforced plastic cultivating barrel, LED lighting for optimal daylight simulation, and a nutrient-recycling mechanism with deflectors and spoiler flaps to evenly distribute nutrients, allowing for efficient water reuse and easy harvesting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional seawater-based cultivation is used, then the shellfish can access natural nutrients, but the water flow and environmental conditions cannot be controlled leading to low survival rate
Solution Approach 1:
The cultivation system is divided into multiple independent floor nets within a controlled tank structure, allowing each layer to be managed separately while maintaining overall environmental control through the enclosed system
Solution Approach 2:
A controlled indoor tank system serves as an intermediary between natural seawater and the shellfish, providing regulated water flow, temperature, and nutrient delivery while protecting from harmful environmental variations
2Ease of operation
If indoor aquafarming box is used, then environmental control is improved, but water purity deteriorates due to contamination from food remnants and excrements requiring frequent manual water changing
Solution Approach 1:
The system implements continuous water circulation and filtration through pumps and filtering devices that constantly remove contaminants and maintain water purity without requiring manual intervention
Solution Approach 2:
The aquafarming system performs self-maintenance through automated filtration and water circulation mechanisms that continuously cleanse the water, eliminating the need for frequent manual water changing
3Productivity
If single-floor net assembly is used, then the system is simple to operate, but the cultivating area is limited reducing productivity
Solution Approach 1:
The system transitions from a single-plane cultivation to multi-layer vertical stacking of floor nets,充分利用 three-dimensional space within the tank to dramatically increase cultivating area without expanding the horizontal footprint
4Productivity
If multi-floor net assembly is used, then cultivating area is increased, but harvesting becomes more difficult requiring more labor
Solution Approach 1:
The floor nets are designed with flexibility and mobility, allowing them to be adjusted, removed, or reconfigured easily, which facilitates harvesting operations across multiple layers without excessive labor

AI summary
An aquafarming system is provided that includes a cultivating barrel with a multi-floor net assembly for the cultivation of shellfish creatures or the like. In the aquafarming system, the use of the multi-floor net assembly allows an increased cultivating area such that the quantity of the shellfish creatures being cultivated can be increased to thereby increase the productivity. At the harvest time, the multi-floor net assembly can be lifted up so as to be separated from the cultivating barrel such that the cultivated shellfish creatures can be easily and conveniently collected to reduced labor time and cost.
