Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a conventional separator design is used, then separation function is achieved, but device size becomes large
Solution Approach 1:
The separator is divided into multiple flow channels (first, second, third flow channels) with different flow rates, allowing each channel to handle specific particle size ranges efficiently. This segmentation enables compact design while maintaining high overall separation efficiency through specialized sub-channels.
Solution Approach 2:
The patent employs a rotating rotor that creates dynamic centrifugal forces to separate particles. The rotation speed can be adjusted to optimize separation for different particle sizes and densities, enabling efficient separation in a compact volume without sacrificing productivity.
2Productivity
If flow rate is increased to improve productivity, then separation efficiency decreases
Solution Approach 1:
The gas flow is divided into multiple channels with different flow rates. The first flow channel handles high flow rate for bulk gas movement, while the second and third flow channels handle lower flow rates for precise particle separation, allowing both high productivity and high separation precision simultaneously.
Solution Approach 2:
Different regions of the separator are assigned different flow rates based on local separation requirements. The patent specifies that the flow rate in each channel differs from others, creating optimal local conditions for separating particles of different sizes and densities at various stages of the separation process.
