Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual operation of vacuum pumps is used, then device complexity is reduced, but vacuum control precision deteriorates and tissue damage increases
Solution Approach 1:
The patent implements a feedback mechanism where a sensor continuously monitors the vacuum level and provides real-time information to a control circuit. The control circuit adjusts the pump operation based on this feedback to maintain the desired vacuum level, thereby achieving precise control without excessive complexity.
Solution Approach 2:
The vacuum pump system is designed to automatically regulate its own operation through the sensor and control circuit integration. The system self-adjusts vacuum levels without requiring manual intervention, reducing the operational burden on the user while maintaining precision.
2Object-affected harmful factors
If continuous vacuum monitoring is implemented, then tissue damage is reduced, but device complexity increases
Solution Approach 1:
A sensor continuously monitors vacuum levels and provides real-time feedback to the control circuit, which automatically adjusts pump operation to prevent excessive vacuum that could cause tissue damage. This closed-loop system ensures safe operation while managing complexity through automation.
Solution Approach 2:
The patent replaces manual mechanical control with an automated electronic control system that uses sensors and control circuits to regulate vacuum levels, eliminating the need for operator judgment and reducing the risk of tissue damage through precise, continuous monitoring.
3Measurement precision
If automated vacuum control is used, then vacuum precision is improved, but ease of operation deteriorates
Solution Approach 1:
The vacuum pump system automatically regulates its own operation through integrated sensors and control circuits, eliminating the need for manual adjustment. The system self-adjusts vacuum levels based on real-time monitoring, making it as easy to use as simply attaching the device to the tissue.
Solution Approach 2:
The feedback mechanism allows the system to automatically maintain optimal vacuum levels without user intervention. The sensor continuously monitors conditions and the control circuit makes real-time adjustments, freeing the operator from complex manual control while maintaining precision.

AI summary
In various embodiments of the invention, an electro-vacuum pump can be used either as a stand alone unit to create, monitor and control a vacuum or to maintain, assist or as a back up for a hand operated pump in a variety of surgical procedures. The vacuum pump is controlled by a processor and is automatically activated when the vacuum is below a pre-selected parameter or a parameter selected on the fly by the surgeon. Visual or audio feedback is used to allow the surgeon increased control of the vacuum device while carrying out the surgical procedure.
