Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If high-speed rotation is implemented to increase shaking intensity, then the shaking effectiveness is improved, but the positioning accuracy deteriorates
Solution Approach 1:
The patent employs a Hall sensor to detect the position of the motion platform and feeds this information back to the control system. The control system compares the actual position with the preset position and adjusts the servo motor accordingly, enabling accurate positioning even during high-speed operation and immediate stopping.
2Productivity
If high-speed shaking operation is performed, then the oxygenation and nutrient transfer are improved, but the stopping precision deteriorates
Solution Approach 1:
The Hall sensor continuously monitors the position of the motion platform and provides feedback to the control system. When stopping is required, the control system uses this real-time position information to precisely control the servo motor, ensuring the platform stops exactly at the preset position regardless of the operating speed.
3Loss of time
If immediate stopping is implemented to enable quick repositioning, then the operational flexibility is improved, but the positioning accuracy deteriorates
Solution Approach 1:
The control system uses real-time feedback from the Hall sensor to monitor the motion platform's position during rapid deceleration. This enables the system to make precise adjustments even during immediate stopping operations, ensuring the platform reaches the correct position without sacrificing accuracy despite the quick response time.
