Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If particles are fed in high concentration flow, then processing throughput is increased, but particle spacing becomes insufficient causing jamming in downstream devices
Solution Approach 1:
The device segments the particle flow into individual particles using a flow cell with controlled geometry. The flow cell divides the high-concentration input stream into separate flow paths, ensuring particles are spaced adequately as they travel through the device, thus preventing jamming while maintaining high throughput processing capability
Solution Approach 2:
The device performs preliminary particle spacing action within the flow cell before particles enter downstream processing devices. By controlling the flow dynamics and cell geometry, particles are pre-positioned with adequate spacing, eliminating the need for downstream adjustment and ensuring reliable operation of subsequent equipment
2Adaptability or versatility
If flow channel path or size changes, then device functionality is enhanced, but particles get jammed due to flow disruption
Solution Approach 1:
The device incorporates dynamic flow control mechanisms that adjust flow characteristics in response to particle presence. Flow rates and pressure gradients are modulated to maintain smooth particle passage through varying channel geometries, preventing jamming while allowing the device to adapt to different operational requirements
Solution Approach 2:
Sensors detect particle position and flow conditions in real-time, providing feedback to control systems. This feedback enables automatic adjustment of flow parameters to maintain continuous particle flow through changing channel configurations, preventing jamming while preserving enhanced device functionality
3Adaptability or versatility
If image processing is used to sort particles, then sorting capability is achieved, but processing time increases and efficiency decreases
Solution Approach 1:
The device performs preliminary particle positioning and spacing within the flow cell before particles reach the imaging and sorting stage. By pre-organizing particles with adequate spacing and predictable trajectories, the image processing system requires less computational time for analysis and sorting decisions, reducing overall processing time while maintaining sorting capability
