Solution Overview
Problem
Current centrifuges are limited in their ability to efficiently separate fluids with varying masses and densities across multiple axes, which restricts their effectiveness in achieving precise separation and mixing of particles.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a traditional single-axis centrifuge is used, then the structure is simple, but the separation precision for particles with varying masses and densities is insufficient
Solution Approach 1:
The patent transitions from single-axis rotation to multi-axis (three-axis) rotation, adding dimensional complexity to the centrifugal separation process. This enables particles to be separated based on their mass distribution across multiple planes simultaneously, achieving precise separation of particles with varying masses and densities that cannot be accomplished with traditional single-axis centrifuges.
Solution Approach 2:
The multi-axis centrifuge system can perform multiple functions: separation along different axes, mixing of particles, and formation of distinct particle rings. By integrating these functions into a single apparatus with independently operable motors for each axis, the system achieves high separation precision without requiring multiple separate devices.
2Measurement precision
If multiple separate centrifuges are used to separate particles across different planes, then the separation precision improves, but the device complexity and space requirements increase
Solution Approach 1:
The patent combines multiple centrifugal separation functions into a single multi-axis centrifuge apparatus. By integrating three independent rotation axes within one device, it achieves the separation precision that would otherwise require multiple separate centrifuges, while reducing space requirements and overall system complexity.
Solution Approach 2:
The single multi-axis centrifuge performs multiple separation functions simultaneously across different planes and axes. The independently operable motors allow each axis to be controlled separately, enabling the device to handle diverse separation requirements that would traditionally require multiple specialized centrifuges.
3Productivity
If a multi-axis centrifuge system is implemented, then the separation and mixing efficiency improves, but the control complexity increases
Solution Approach 1:
The system employs dynamically controllable rotation speeds for each of the three independent axes. The independently operable motors allow real-time adjustment of rotational velocities to optimize separation and mixing processes, enabling high productivity through adaptive control rather than fixed operational parameters.
Solution Approach 2:
The control system is segmented into independent motor controllers for each rotation axis. This modular control approach allows each axis to be controlled and optimized independently, reducing the overall control complexity compared to a coupled system, while still achieving high separation efficiency through coordinated multi-axis operation.

This approach allows for precise separation and mixing of particles by adjusting rotational velocities and axes, resulting in effective separation of heavier and lighter mass particles across multiple planes, enhancing the efficiency of fluid separation and mixing processes.

Implementation Method 2
The centrifuge works using the sedimentation principle, where centripetal acceleration causes denser substances and particles that are held within the spinning container, to move outward in the radial direction. At the same time, objects that are less dense are displaced and forced toward the axis of spin
