Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cooling system monitors fluid flow and temperature without real-time comparison, then system complexity is reduced, but reliability of temperature monitoring deteriorates due to inability to detect phase drift
Solution Approach 1:
The system continuously compares inflow fluid temperature with outflow fluid temperature to provide real-time feedback on cooling system performance. This feedback mechanism enables detection of phase drift and cooling malfunctions, improving temperature monitoring reliability through active monitoring and comparison of temperature parameters across the cooling circuit.
2Object-affected harmful factors
If laser energy output is not adjusted based on cooling system status, then device operation is simplified, but harmful effects increase due to hyperthermia of non-diseased tissue
Solution Approach 1:
The system automatically adjusts laser energy output based on real-time cooling system status by comparing inflow and outflow temperature parameters. When phase drift or cooling malfunction is detected, the system provides feedback to control the laser energy delivery, thereby preventing hyperthermia of non-diseased tissue through automated, condition-based laser parameter adjustment.
3Reliability
If real-time comparison of inflow and outflow parameters is implemented, then detection of phase drift and malfunctions is improved, but loss of time increases due to additional monitoring and processing
Solution Approach 1:
The system implements continuous real-time comparison of inflow and outflow temperature parameters throughout the laser ablation procedure. This continuous monitoring enables immediate detection of phase drift and cooling malfunctions without interruption to the ablation process, maintaining useful action continuity while providing constant reliability feedback.
