Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional fluid separation devices are used, then separation function is achieved, but device complexity and manufacturing cost increase
Solution Approach 1:
The device is divided into multiple compartments (first compartment, second compartment, third compartment, fourth compartment) that can be manufactured separately and then assembled together. Each compartment performs a specific function in the separation process, allowing for simplified individual manufacturing while achieving complex overall functionality through modular assembly.
Solution Approach 2:
The compartments are designed to be nested or interconnected in a compact arrangement where the second compartment is communicated with the first, the third with the second, and the fourth with the third. This nesting approach reduces the overall device footprint and simplifies the manufacturing process by integrating multiple functions into a compact structure.
2Ease of manufacture
If conventional fluid separation devices are used, then separation function is achieved, but manufacturing cost increases due to micromaching technology
Solution Approach 1:
The invention replaces complex micromaching technology with a mechanical rotation system. By rotating the second compartment about a reference axis, the device utilizes centrifugal and Coriolis forces to achieve fluid separation without requiring precision micromachined channels. This substitution dramatically reduces manufacturing costs while maintaining separation effectiveness.
Solution Approach 2:
The invention changes the separation mechanism from static micromachined channels to dynamic force fields generated by rotation. By controlling rotational speed and direction, the device can adjust separation parameters to achieve effective separation of different fluid components without requiring complex precision manufacturing.
3Productivity
If rotation is used for separation, then separation efficiency improves, but operation complexity increases
Solution Approach 1:
The device employs periodic rotation of the second compartment about the reference axis. By rotating in a first direction to achieve separation, then stopping and rotating in a second direction for component transmission, the system creates periodic action that simplifies operation while maintaining high separation efficiency. The periodic nature allows for automated control and reduces operational complexity.

AI summary
An analytical system includes a working fluid, a uniform dividing unit and a separating unit. The working fluid includes a first component and a second component with different characteristics. The uniform dividing unit is utilized to uniformly divide the working fluid and relatively rotated with respect to a reference axis. Under a capillarity force as well as the result of Coriolis force and siphon force, the first component can be separated from the second component by the separating unit.
