Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for separating live food organisms from unhatched cysts and empty cyst shells in aquaculture are time-consuming and often cause damage to the organisms.
Innovation Solution
A method involving cysts with a catalyst on their surface, incubated in a liquid medium, where the catalyst reacts with a gas-producing reagent to generate bubbles, causing unhatched cysts and shells to surface, allowing for efficient separation from live food organisms using a filtration system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional separation techniques are used to separate live food organisms from unhatched cysts and empty cyst shells, then separation is achieved, but the process is time-consuming and causes damage to the live food organisms
Solution Approach 1:
The patent applies preliminary action by coating the cysts with a catalyst before incubation. This pre-preparation enables the cysts to react with gas-producing reagents later, creating bubbles that attach to unhatched cysts and empty shells, causing them to surface for easy separation. The live food organisms, being smaller and without catalyst coating, remain in the liquid phase and are not damaged during separation.
Solution Approach 2:
The patent uses gas-producing reagents as an intermediary substance. When these reagents react with the catalyst on the cyst surfaces, they generate bubbles that act as a mediator to attach to unhatched cysts and empty shells. This intermediary mechanism enables selective buoyancy and separation without direct mechanical contact that could damage the live food organisms.
2Loss of time
If conventional separation techniques are used, then separation is achieved, but the process is time-consuming
Solution Approach 1:
By pre-coating cysts with catalyst during the incubation phase, the separation process is dramatically accelerated. When gas-producing reagents are added, bubbles immediately form on unhatched cysts and empty shells, causing rapid surfacing and separation. This eliminates time-consuming manual or mechanical separation steps, significantly reducing loss of time and improving production efficiency.
Solution Approach 2:
The patent replaces mechanical separation systems with a chemical-biological mechanism. Instead of using time-consuming mechanical filtration, centrifugation, or manual sorting, the invention uses catalytic reactions with gas-producing reagents to create buoyancy differences. This substitution of mechanical methods with chemical-biological processes dramatically reduces separation time and improves productivity.
