Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fish heading machines are costly and inefficient in positioning the fish to remove the head without losing usable meat, as they require complex form-fitting and coupling mechanisms.
Innovation Solution
A method and device using a displaceable pressure part to gently push the fish's head towards its body, leveraging the fish's smooth surface and fins to position it correctly for heading, with a four-bar chain control system for precise movement and minimal space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If complex form-fitting and coupling mechanisms are used to position the fish, then positioning precision is improved, but device complexity and cost increase
Solution Approach 1:
The fish's own anatomical features (smooth surface, fins, gills) are utilized to achieve positioning. The fish's body shape and surface properties enable it to be guided and positioned by simple mechanical elements without requiring complex form-fitting mechanisms. The fish essentially positions itself through its interaction with the simple guiding structures.
Solution Approach 2:
The invention extracts and utilizes the key functional properties of the fish (smooth surface, fins, gills) that enable positioning, while removing the need for complex positioning mechanisms. By focusing on these essential features, the system achieves effective positioning with minimal mechanical complexity.
2Manufacturing precision
If complex displacement mechanisms are used to position the fish, then positioning precision is improved, but ease of operation deteriorates
Solution Approach 1:
The fish's anatomical features (smooth surface, fins, gills) are harnessed to enable simple mechanical elements to effectively position the fish. The fish's own properties facilitate the positioning operation, making the system easy to operate while maintaining precision.
Solution Approach 2:
The invention replaces complex, expensive positioning mechanisms with simple, inexpensive mechanical elements. These simple elements are sufficient for the task and can be easily replaced or adjusted, improving ease of operation while maintaining positioning precision.
3Volume of moving object
If vertical displacement of pressure part is used, then space requirement is reduced, but positioning speed may be limited
Solution Approach 1:
The pressure part is designed to be movable in both vertical and horizontal directions, allowing it to dynamically adapt to the fish's position and movements. This dynamic capability enables the system to maintain compact dimensions while achieving rapid positioning by following the fish's natural movements.
Solution Approach 2:
The pressure part utilizes both vertical and horizontal displacement dimensions to position the fish. By operating in multiple dimensions, the system achieves efficient positioning within a compact space, as the horizontal movement allows rapid adjustment without requiring large vertical travel distances.

AI summary
A method and device for positioning a fish is presented. In an exemplary method, a fish is positioned in relation to a cutting plane. Pressure is applied to a rising area of the fish's head via a pressure part such that the fish is displaced in the direction of the fish's body, thereby positioning the fish for heading. Thereafter, the fish is headed. In another embodiment, an exemplary device for positioning a fish in a heading machine comprises a pressure part having a pressure surface configured to be lowered onto to a surface area of the fish that is rising relative to the substrate on which the fish is placed. The pressure surface is configured to slide against the rising area of the fish. Under a force of the pressure surface of the pressure part being lowered onto the rising area of the fish, the fish is displaced and positioned for heading.
