Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for suctioning intracellular substances are inefficient due to the need for manual visualization of the suction tip, resulting in low positional precision and reduced ability to process multiple cells effectively.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual visualization of the suction tip is used, then the system is simple to operate, but the positional precision is low and processing efficiency is reduced
Solution Approach 1:
The patent replaces manual visual observation with an optical detection system that uses a microscope and camera to automatically detect the position of the suction tip front end. This substitution of mechanical/visual methods with optical detection systems enables precise automated positioning while maintaining operational simplicity through computer control.
Solution Approach 2:
The patent introduces an optical intermediary system (microscope and camera) that acts as a mediator between the suction tip and the control system. This intermediary captures optical images of the suction tip position and transmits this information to the computer, enabling precise positioning without direct manual visualization.
2Productivity
If manual cell-by-cell analysis is performed, then each cell can be carefully examined, but the processing speed is slow and productivity is low
Solution Approach 1:
The system enables self-service operation where the computer automatically controls the suction section positioning based on detection section feedback. The operator simply needs to initiate the process, and the system autonomously performs the repetitive tasks of positioning and suction, dramatically improving productivity while reducing manual time investment.
Solution Approach 2:
The patent implements a feedback control loop where the detection section continuously monitors the suction tip position and provides this information to the computer, which then adjusts the conveyance section to maintain precise positioning. This real-time feedback enables fast, accurate automated operation across multiple cells.
3Manufacturing precision
If the suction tip position is controlled manually, then the system is easier to operate, but the precision in guiding the tip to specific cells is insufficient
Solution Approach 1:
The patent replaces manual mechanical positioning with computer-controlled automated positioning. The computer receives detection information about the suction tip position and automatically controls the conveyance section to achieve precise positioning, eliminating the need for manual operation while dramatically improving precision.
Solution Approach 2:
The optical detection system serves as an intermediary that provides precise positional information to the computer control system. This intermediary enables the computer to accurately determine and adjust the suction tip position, achieving high precision without requiring manual skill or effort.
