Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single set of parallel metallic plates is used for droplet deflection, then the device structure is simple, but the droplet can only be deflected at limited angles
Solution Approach 1:
The droplet deflector is divided into multiple independent sets of parallel metallic plates, each set capable of deflecting droplets at different angles. This segmentation allows the system to achieve multi-angle deflection capability while maintaining the simplicity of individual plate sets.
Solution Approach 2:
Multiple sets of parallel metallic plates are arranged in different spatial orientations and positions along the flow stream. By adding the spatial dimension of plate arrangement, the system can deflect droplets at multiple angles without increasing the complexity of individual plate structures.
2Measurement precision
If multiple sets of parallel metallic plates are used to deflect droplets at various angles, then the sorting precision is improved, but the device complexity increases
Solution Approach 1:
Each set of parallel metallic plates functions as an independent deflection unit with a specific deflection angle. This segmentation enables precise control over droplet trajectories for different particle types, improving sorting precision while keeping each unit structurally simple.
Solution Approach 2:
The system can dynamically select which set of parallel metallic plates to activate based on the sorting requirements. This dynamic operation allows the device to achieve high sorting precision for different particle types without requiring all plate sets to be active simultaneously, thereby managing device complexity.
3Force
If the parallel metallic plates are spaced closely together, then the deflection force is concentrated, but the droplet deflection distance is limited
Solution Approach 1:
Multiple sets of parallel metallic plates are arranged both closely together (to concentrate deflection force) and at different positions along the flow stream (to extend deflection distance). This spatial arrangement in multiple dimensions allows the system to achieve both concentrated force and extended deflection range.
Solution Approach 2:
The multiple sets of parallel metallic plates are positioned sequentially along the flow stream, creating a continuous deflection action. As droplets pass through each set, they receive cumulative deflection, extending the overall deflection distance while maintaining concentrated force at each stage.
4Length of moving object
If the parallel metallic plates are spaced apart by large distances, then the droplet deflection distance increases, but the deflection force is reduced
Solution Approach 1:
The deflection process is segmented into multiple stages, with each set of parallel metallic plates providing a concentrated deflection force at its specific location. This segmentation allows the system to maintain high deflection force at each stage while achieving large overall deflection distance through the cumulative effect of multiple stages.
Solution Approach 2:
Multiple sets of parallel metallic plates are arranged in different spatial positions along the flow stream. This spatial distribution allows the system to apply concentrated deflection forces at multiple points, achieving both sufficient deflection force and extended deflection distance simultaneously.
