Fish Extractor With Segmented Cutting And Movable Wings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fish processing systems often cause damage to the gonads or the fish structure during processing, leading to downgraded fish products and increased labor costs, especially when dealing with variations in fish size, shape, and firmness, and the strong connection between the viscera and the fish body.
Innovation Solution
A fish processing system that includes an extractor positioned below the backbone and above the gullet, with cutting members to sever the kidney and peritoneum membranes, and movable wing members to gather and separate the viscera without significant damage, allowing for precise control and adjustment during the gutting operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional gutting machines are used to remove viscera, then the viscera can be removed from the fish, but the gonads or fish structure are damaged during processing
Solution Approach 1:
The extractor is divided into distinct functional segments: a leading tip for insertion, cutting members for severing membranes, and wing members for gathering viscera. This segmentation allows each part to perform its specific function with precision, minimizing damage to the gonads while efficiently removing viscera.
Solution Approach 2:
The cutting members are positioned to cut the kidney and peritoneum membranes before the viscera are fully exposed. This preliminary action separates the membranes from the belly walls, preventing them from being pulled or ripped away and exposing the belly meat to damage.
Solution Approach 3:
The extractor acts as an intermediary tool between the processing machine and the fish viscera. It provides a controlled interface that allows for the removal of viscera while protecting the gonads through its designed structure and positioning.
2Stability of the object's composition
If the gullet is not cut free from the body, then the fish structure remains intact, but the viscera do not separate from the fish and the roe or milt is damaged
Solution Approach 1:
The extractor applies localized cutting action at specific locations where the gullet connects to the collar and where the viscera attach to the gullet. This localized approach allows the gullet to be severed from the collar while maintaining the integrity of the rest of the fish structure, and enables viscera separation without damaging the gonads.
3Productivity
If known processing systems are used, then fish can be processed, but they cannot effectively adjust to variations in fish size, shape and firmness
Solution Approach 1:
The extractor and wing members are designed with movable components that can dynamically adjust their position and configuration. The wing members can move between open and closed configurations, and the extractor can be repositioned to accommodate different fish sizes, shapes, and firmness levels, allowing the system to adapt to variations while maintaining processing efficiency.

AI summary
Methods and systems for processing fish are provided which enable cutting of the fish and removal of the viscera without damage to either the viscera or the remaining fish product. The systems may include a gutting device to severe a gullet of the fish from the fish body and to gather and remove the viscera without significant damage to the viscera or the remaining fish product. Extractors for severing the connection between the gullet and the fish with one or more underlying cutting members are also provided to assist in removal of the viscera.
