Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing fish processing systems face challenges due to random fluctuations in fish size and weight, leading to inefficient processing as machines are not optimally adjusted for varying fish dimensions, requiring separate processing lines or presetting machines, which limits optimal processing to fish within a specific size or weight range.
Innovation Solution
A system comprising a fish slaughtering device with a counting device, a spiral conveyor tank, and a control unit that calculates fish quantity-related prediction variables, including average fish weight and size distribution, to estimate fish loading status and adjust processing machines accordingly, ensuring optimal processing and efficient fluid flow around the fish.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If fish are processed without size classification, then processing speed increases, but processing quality deteriorates because machines cannot be optimally adjusted for varying fish sizes
Solution Approach 1:
The system performs preliminary measurement of fish dimensions and weight before processing, using sensors to capture fish parameters. This advance information allows the control system to pre-adjust machine settings for each fish, ensuring optimal processing quality without requiring manual sorting or classification, thus maintaining high processing speed while improving manufacturing precision
Solution Approach 2:
The processing machines are equipped with dynamically adjustable parameters that can be modified in real-time based on measured fish characteristics. The control system continuously adapts machine settings (such as cutting depth, conveyor speed, or processing force) according to the specific size and weight of each fish, enabling optimal processing quality across varying fish dimensions without sacrificing productivity
2Manufacturing precision
If fish processing machines are preset to a specific size, then processing quality improves for that size range, but adaptability deteriorates for fish outside the range
Solution Approach 1:
The system replaces fixed preset settings with dynamically adjustable parameters that can be modified in real-time based on measured fish characteristics. Sensors detect fish dimensions and weight, and the control system automatically adjusts machine settings (such as cutting depth, conveyor speed, or processing force) for each fish, enabling optimal processing quality across varying fish dimensions without requiring manual reconfiguration
Solution Approach 2:
The system implements a feedback mechanism where sensors continuously measure fish parameters during processing, and this information is fed back to the control system which automatically adjusts machine settings. This closed-loop control ensures that processing parameters are continuously optimized based on actual fish characteristics, maintaining high processing quality while handling a wide range of fish sizes
3Manufacturing precision
If fish are divided between different processing lines, then processing quality improves for each line, but device complexity increases
Solution Approach 1:
The system employs a universal processing machine that can handle fish of various sizes through programmable and dynamically adjustable parameters. Instead of requiring multiple specialized processing lines, a single machine equipped with sensors and adaptive control can process different fish sizes by automatically adjusting its parameters, thereby reducing device complexity while maintaining processing quality
Solution Approach 2:
The system achieves the functionality of multiple processing lines by changing operational parameters (such as speed, force, temperature, or positioning) rather than requiring physically separate lines for different fish sizes. The control system modifies these parameters based on measured fish characteristics, allowing one machine to perform the work of multiple specialized machines, thus reducing overall system complexity
