Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fish ensilation systems face challenges in efficiently processing large quantities of fish during emergency slaughtering, as they lack sufficient grinding and storage capacity, leading to issues with viscosity, stickiness, and the risk of infection, and require additional water and ensiling liquid, which increases costs and environmental impact.
Innovation Solution
A float for ensilation with closed compartments, a grinder inlet, and a dosing device for ensiling liquid, combined with a rough stirring propeller to prevent bone deposition and ensure thorough mixing, allowing for efficient grinding, storage, and acidification of fish mass, enhancing capacity and hygiene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If water is added to reduce stickiness of ground fish mass, then pumpability is improved, but processing costs and environmental impact increase
Solution Approach 1:
The patent applies preliminary action by dosing ensiling liquid to the ground fish mass during the grinding process itself, rather than adding water after grinding. This timing allows the ensiling liquid to be incorporated at the optimal moment, achieving proper consistency without requiring additional water that would later need evaporation or disposal.
Solution Approach 2:
The patent changes the parameter of liquid addition timing and type. Instead of adding water after grinding, it doses ensiling liquid during grinding, which simultaneously achieves the desired consistency and initiates the ensiling process. This parameter change eliminates the need for subsequent water evaporation and reduces overall liquid requirements.
2Ease of operation
If water is added to improve pumpability, then flow properties are improved, but additional ensiling liquid and base are required, increasing costs
Solution Approach 1:
The dosing device adds the correct amount of ensiling liquid during grinding, performing the liquid addition action in advance. This preliminary dosing ensures proper flow properties are achieved immediately, eliminating the need for subsequent water additions and the associated extra ensiling liquid and neutralization base.
Solution Approach 2:
The system uses the ensiling liquid itself to achieve proper flow properties, rather than using water as a separate step. The ensiling liquid serves dual purposes: it provides the necessary consistency for pumping and initiates the ensiling process, making the system self-sufficient and eliminating additional material requirements.
3Ease of operation
If water is added without sufficient mixing, then viscosity is reduced, but fermentation risk increases in insufficiently ensiled parts
Solution Approach 1:
The dosing device performs preliminary action by adding ensiling liquid during grinding, ensuring the liquid is distributed throughout the mass before pumping begins. This timing ensures proper mixing occurs during the grinding process itself, eliminating pockets of insufficiently ensiled material that could ferment.
Solution Approach 2:
The patent merges the mixing action with the grinding process. The grinder simultaneously performs size reduction and mixing functions, while the dosing device adds liquid during this combined operation. This merging ensures uniform distribution of ensiling liquid throughout the ground mass, preventing fermentation risks.
4Volume of stationary object
If existing ensiling tank capacity is used, then storage is maintained, but emergency slaughtering capacity is insufficient
Solution Approach 1:
The patent applies dynamics by making the ensiling system mobile through the floating platform. Instead of a fixed tank with limited capacity, the system can be positioned at different locations around the fish farm, effectively increasing the available processing capacity for emergency slaughtering while maintaining adequate storage volume.
Solution Approach 2:
The system segments the ensiling function from the fixed farm infrastructure by using a separate floating platform. This segmentation allows the ensiling capacity to be independently scaled and positioned, enabling emergency slaughtering operations without being constrained by the fixed tank capacity of the main farm facility.
5Ease of operation
If fixed feeding float is used, then feeding function is provided, but mobility for emergency response is lost
Solution Approach 1:
The floating platform performs multiple functions: it can conduct regular feeding operations when positioned at the fish farm, and it can be moved to different locations for emergency slaughtering and disease outbreak response. This multi-functionality provides both feeding capability and mobility, resolving the contradiction between fixed operation and adaptability.
Solution Approach 2:
The system transitions from a fixed feeding float to a dynamic floating platform that can change position as needed. The platform maintains its feeding function while gaining the ability to move to different locations, providing both operational ease and adaptability for emergency responses throughout the fish farm area.
