Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation of medical imaging device is used, then operator can control imaging parameters, but operation complexity and surgical time increase
Solution Approach 1:
The system enables self-service operation by automatically controlling the medical imaging device based on navigation data. The computer determines operating parameters (scan range, gantry tilt, tube voltage) autonomously without requiring manual intervention from the operator, thus simplifying operation and reducing surgical time simultaneously
Solution Approach 2:
The system performs preliminary actions by pre-determining the imaging parameters based on the planned surgical procedure and navigation data. The computer calculates and sets the scan range, gantry tilt angle, and tube voltage before actual imaging begins, eliminating the need for time-consuming manual adjustments during surgery
2Productivity
If automatic control is implemented, then surgical time is reduced, but control precision may be compromised
Solution Approach 1:
The system uses feedback from the navigation system to continuously monitor and adjust imaging parameters. The computer receives real-time position data from the navigation system and automatically adjusts the medical imaging device parameters to maintain precise alignment with the planned surgical trajectory, ensuring both speed and accuracy
Solution Approach 2:
The system replaces manual mechanical adjustment with automated computer control. The computer calculates optimal imaging parameters based on navigation data and automatically controls the device, substituting human operator precision with algorithmic precision that maintains high accuracy while enabling faster operation
3Reliability
If multiple imaging scans are performed, then surgical target identification is improved, but radiation exposure increases
Solution Approach 1:
The system optimizes radiation parameters by dynamically adjusting tube voltage and scan range based on the specific surgical requirements and real-time navigation data. The computer determines the minimum necessary scan parameters to achieve reliable target identification, reducing radiation exposure while maintaining diagnostic quality
Solution Approach 2:
The system applies partial action by performing only the necessary imaging scans required for the specific surgical procedure. The computer analyzes navigation data to determine the precise scan range and timing, avoiding unnecessary scans and reducing cumulative radiation exposure while ensuring adequate target identification
