Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed power levels are applied to the ultrasonic transducer, then the device structure remains simple, but the energy delivery cannot adapt to real-time tissue conditions leading to inefficiency and potential tissue damage
Solution Approach 1:
The control circuit receives feedback signals from sensors that detect tissue properties and mechanical characteristics during ultrasonic operation. Based on this feedback, the control circuit dynamically adjusts the power level applied to the ultrasonic transducer, enabling real-time adaptation to varying tissue conditions while maintaining safe and effective energy delivery.
Solution Approach 2:
The system transitions from static fixed power levels to dynamic power adjustment. The control circuit continuously modifies the power level applied to the ultrasonic transducer based on real-time detection of tissue mechanical properties and operational conditions, allowing the device to adapt its energy delivery to match the specific requirements of different tissue types and surgical stages.
2Productivity
If higher power levels are applied to improve cutting and coagulation efficiency, then surgical productivity increases, but tissue damage and harmful effects increase
Solution Approach 1:
Sensors detect mechanical properties and operational parameters of the ultrasonic blade in real-time, providing feedback to the control circuit. The control circuit uses this information to precisely regulate power delivery, ensuring sufficient energy for effective cutting and coagulation while preventing excessive power application that could cause tissue damage or thermal injury.
Solution Approach 2:
The system dynamically changes the power level parameter applied to the ultrasonic transducer based on detected tissue properties and mechanical characteristics. By adjusting this critical parameter in real-time, the system optimizes the balance between achieving surgical efficiency through adequate energy delivery and minimizing tissue damage by preventing excessive energy application.
