Micromanipulator Control Switching for Precise Cell Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing micromanipulator control systems are inflexible and inconvenient, particularly when manipulating biological cells, as they require repeated joystick movements and can cause mechanical stress, making precise control over small distances challenging.
Innovation Solution
The operating apparatus allows for intuitive, single-handed control by automatically switching between proportional and dynamic control modes based on the user's input, using a movable element like a joystick or fingertip within defined input zones, enabling precise and efficient movement of tools in micromanipulation tasks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If repeated joystick movements are used to move the tool over large distances, then the tool can be positioned close to the cell, but mechanical stress on the operating apparatus increases and the operation becomes inconvenient
Solution Approach 1:
The patent implements dynamic control mode where the tool moves at a speed proportional to the distance between the tool and cell, automatically adjusting the movement behavior based on real-time position. This eliminates the need for repeated manual joystick movements and reduces mechanical stress on the operating apparatus.
2Measurement precision
If proportional control is used for fine positioning close to the cell, then precise control is achieved, but the control process becomes time-consuming and inefficient
Solution Approach 1:
The system automatically switches to dynamic control mode when the tool is close to the cell, where the movement speed is proportional to the remaining distance. This maintains positioning precision while dramatically reducing the time required compared to manual proportional control operations.
Solution Approach 2:
The control system automatically determines when to switch between control modes based on the distance between tool and cell, eliminating the need for manual mode switching and reducing operator intervention time.
3Adaptability or versatility
If manual switching between control modes is implemented, then flexibility is provided, but the operation becomes more complex and less intuitive
Solution Approach 1:
The control system automatically selects and switches between proportional and dynamic control modes based on the real-time distance between the tool and cell, providing flexible adaptability without requiring manual intervention. This makes the complex multi-mode control intuitive and effortless for the operator.
