Solution Overview
Problem
In microparticle fractionation technologies, optimizing the timing and magnitude of suction force is crucial for improving fractionation performance, as current methods often result in inefficient recovery of target microparticles due to non-optimized suction conditions, leading to increased worker hours and potential contamination between samples.

Engineering Contradiction Analysis
1Productivity
If suction force is applied to recover target microparticles from the main flow path, then microparticle recovery efficiency is improved, but non-target particles and sample liquid may be incorrectly sucked in, reducing fractionation purity
Solution Approach 1:
The system performs preliminary detection of microparticle presence and identity before applying suction force. The detection unit identifies target microparticles in advance, and the control unit determines optimal suction timing based on this preliminary information, ensuring only target particles are recovered while avoiding contamination with non-target particles
Solution Approach 2:
The system uses feedback from the detection unit to dynamically control the suction force application. The control unit receives real-time information about microparticle presence and adjusts suction timing and magnitude based on detected particle characteristics, optimizing both recovery efficiency and purity through closed-loop control
2Manufacturing precision
If suction timing is delayed to allow target microparticle identification, then fractionation accuracy is improved, but processing time increases, reducing productivity
Solution Approach 1:
The detection unit continuously monitors the main flow path in advance to identify target microparticles before they reach the suction point. This preliminary detection allows the control unit to prepare and execute suction at the optimal moment without delaying particle recovery, maintaining both accuracy and speed
Solution Approach 2:
The system replaces manual timing and suction control with an automated detection and control system. The detection unit and control unit work together to automatically determine optimal suction timing based on real-time particle detection, eliminating the need for manual intervention and significantly improving processing speed while maintaining high accuracy
3Productivity
If strong suction force is applied to ensure complete microparticle recovery, then recovery completeness is improved, but liquid flow disturbance increases, causing contamination and reducing operational reliability
Solution Approach 1:
The system dynamically adjusts the suction force parameter based on detected microparticle characteristics and flow conditions. The control unit modulates suction magnitude to achieve complete particle recovery while maintaining stable liquid flow, preventing excessive disturbance that would cause contamination or operational instability
Solution Approach 2:
The suction force is applied locally and selectively at the position where target microparticles are detected, rather than applying uniform strong suction throughout the flow path. This localized application ensures complete recovery of target particles while minimizing disturbance to the overall liquid flow and maintaining operational stability

AI summary
To provide a technology of optimizing a suction condition of a microparticle. The present technology provides an optimizing method of a suction condition of a microparticle including: a particle number counting step of detecting a time point when a microparticle passes through a predetermined position on a main flow path through which liquid containing the microparticle flows, sucking the microparticle from the main flow path to a microparticle suction flow path by the microparticle suction flow path with a predetermined suction force, and counting the number of microparticles sucked into the microparticle suction flow path; and a step of determining an elapsed time from passage through the predetermined position with which the suction by the microparticle suction flow path should be performed on the basis of a time from the time point when the microparticle passes through the predetermined position on the main flow path until the suction is performed and the number of counted microparticles.
