Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fish positioning devices in automated fish processing suffer from low throughput due to mechanical stress and limited service life, as they require the displacement element to return to its starting position before repositioning, leading to increased wear and reduced processing efficiency.
Innovation Solution
A positioning device with a sliding element and holder that pivots about an axis and is movable in two degrees of freedom, utilizing magnetic restoring means to exert a controlled force for precise positioning and reduce mechanical stress, eliminating the need for spring elements and enhancing maintenance-free operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a mechanical displacement element with crank arm and connecting rod is used to position fish bodies, then the fish bodies can be positioned in the desired position, but the displacement element must return to its starting position after each positioning cycle, reducing throughput and increasing mechanical wear
Solution Approach 1:
The patent replaces the mechanical crank arm and connecting rod system with a magnetic field-based positioning system. The magnetic restoring means generates a magnetic field that automatically restores the sliding element to its rest position without mechanical contact, eliminating the need for the displacement element to return to starting position through mechanical means, thereby increasing throughput while maintaining positioning precision
Solution Approach 2:
The patent introduces a magnetic field as an intermediary between the sliding element and the rest position. The magnetic restoring means creates a magnetic field that acts on the sliding element to guide it back to the rest position, serving as a non-contact mediator that eliminates mechanical wear and reduces positioning cycle time
2Measurement precision
If a mechanical displacement element with crank arm and connecting rod is used to position fish bodies, then the fish bodies can be positioned in the desired position, but the mechanical components are heavily loaded due to change in direction, reducing service life
Solution Approach 1:
The patent replaces the mechanical crank arm and connecting rod system with a magnetic field-based positioning system. The magnetic restoring means generates a magnetic field that automatically restores the sliding element to its rest position without mechanical contact, eliminating the need for the displacement element to return to starting position through mechanical means, thereby increasing throughput while maintaining positioning precision
Solution Approach 2:
The patent employs magnetic restoring means that gradually guide the sliding element back to the rest position through magnetic field forces, cushioning the return motion before mechanical contact occurs. This prevents sudden mechanical impacts and reduces wear on components, extending service life while maintaining positioning accuracy
3Ease of operation
If spring elements are used as restoring means for the sliding element, then the sliding element can be restored to rest position, but the spring elements require frequent cleaning and maintenance to meet hygiene standards
Solution Approach 1:
The patent replaces mechanical spring elements with a magnetic field-based restoring system. The magnetic restoring means generates a magnetic field that acts on the sliding element to restore it to the rest position without physical contact. This eliminates the need for spring elements that would require cleaning and maintenance, meeting hygiene standards while maintaining the restoring function
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution achieves precise positioning with reduced mechanical stress, minimizing wear and increasing the device's service life while preventing fish injuries, thereby enhancing throughput and maintaining hygiene standards.
Implementation Method 1
The magnetic restoring means are set up in such a way that when the body of the fish is displaced they exert a restoring force acting in the direction of displacement on the sliding element
Implementation Method 2
The magnetic restoring means allow the sliding element to be deflected in the sliding position by a pivoting movement relative to the sliding element receptacle
