Net Repair Fastening for Fish Farm Hole and Rift Patching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for repairing holes and rifts in fish farm nets are time-consuming, prone to oversight, and can cause damage to the nets and fish, with limited cost-effectiveness and efficiency.
Innovation Solution
A device comprising a main part and a release part connected by an activation element, with grip-hooks that secure to the net to prevent movement and a locking mechanism for easy deployment and removal using a ROV or diver, ensuring minimal stress on the net and fish.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If visual inspection with divers or ROVs is used to detect holes and rifts in nets, then detection capability is provided, but the method is time-consuming and causes prolonged response times
Solution Approach 1:
The patent integrates detection and repair functions into a single device that can be deployed immediately upon suspicion of damage. The device includes inspection components that can preliminarily assess net integrity before full repair deployment, reducing the need for separate inspection phases and accelerating response time while maintaining detection capability
2Ease of manufacture
If traditional repair methods are used to fix holes and rifts in nets, then repair function is provided, but the methods cause damage to the nets and fish
Solution Approach 1:
The patent employs flexible repair elements and thin film patches that conform to the net structure without requiring rigid fixtures or aggressive fastening methods. These flexible components repair holes and rifts while minimizing stress concentration and preventing damage to surrounding net material and nearby fish
Solution Approach 2:
The device uses intermediary repair elements that mediate between the damaged net areas and the surrounding healthy net structure. These intermediary components distribute loads and stresses evenly, preventing further damage propagation while maintaining net integrity and protecting fish from harm
3Duration of action of stationary object
If permanent repair solutions are deployed in nets, then durability is improved, but the device complexity and cost increase
Solution Approach 1:
The patent divides the repair system into modular segments that can be independently deployed and configured. Each segment contains standardized repair components that can be assembled in various configurations depending on the specific damage pattern, providing durable repair without requiring complex integrated systems for each repair scenario
Solution Approach 2:
The device incorporates universal repair components that can address multiple types of damage (holes, rifts, frayed edges) with a single standardized system. These multi-functional elements provide durable repair across different damage scenarios while reducing overall device complexity by eliminating the need for specialized components for each damage type
