Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional separation methods are used for Euphausia superba shells, then the separation process is simple, but the separation is incomplete and the separation effect is poor
Solution Approach 1:
The device segments the separation process into multiple functional zones: a stirring zone with rotating blades for initial shell detachment, a screening zone with mesh screens for separation, and a washing zone with spray nozzles for cleaning. This segmentation allows each zone to perform its specific function optimally, achieving complete separation while maintaining manageable device complexity through modular design
Solution Approach 2:
The device employs a nested structure where the screening cylinder with mesh screens is positioned inside the main processing chamber, and the stirring blades are arranged concentrically within the screening zone. This nesting allows multiple separation mechanisms to occupy overlapping spatial zones, improving separation completeness without proportionally increasing the device's external dimensions
2Productivity
If simple stirring is used during separation, then the device structure is simple, but the separation efficiency is low
Solution Approach 1:
The stirring mechanism transitions from static to dynamic operation with multiple rotating blades that can rotate at different speeds and directions. The screening cylinder also rotates to enhance the separation effect. This dynamic operation significantly improves separation efficiency by creating multiple motion patterns that prevent shells and shrimp bodies from settling in fixed positions, while the modular rotating components keep the overall device complexity manageable
Solution Approach 2:
The stirring blades operate in periodic cycles of rotation and reversal, creating alternating flow patterns that continuously redistribute the shrimp and shell mixture. This periodic action prevents dead zones and ensures thorough separation over time, improving productivity while using a relatively simple reciprocating mechanical mechanism
3Manufacturing precision
If no cleaning is performed during separation, then the process is simple, but the separation effect is not improved
Solution Approach 1:
The device incorporates a hydraulic cleaning system with spray nozzles that喷射 water onto the shrimp and shells during the separation process. This water spray helps detach remaining shell fragments and cleans the screening surfaces, improving separation effectiveness. The hydraulic system is integrated into the existing device structure, adding cleaning functionality without substantially increasing overall complexity
