Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the microwave generator uses fixed operating thresholds, then the system is simple to operate, but it cannot adapt to different device types and changing user needs
Solution Approach 1:
The system performs preliminary device identification by measuring resistance values before operation begins. The device ID reader measures the resistance of the connected microwave instrument, and the generator controller compares this measured resistance with stored resistance value indicators to identify the device type in advance, allowing the system to automatically configure appropriate operating thresholds before the ablation procedure starts
Solution Approach 2:
The microwave generator automatically configures its operating parameters by reading the device ID from the connected instrument. The system self-determines the appropriate operating thresholds by comparing the measured resistance with stored indicators and automatically selecting the corresponding configuration, eliminating the need for manual setup and reducing system complexity while improving adaptability
2Adaptability or versatility
If the microwave generator manually configures operating parameters, then the system is easy to understand, but it cannot keep up with latest technologies and changing needs
Solution Approach 1:
The system performs preliminary device identification by measuring resistance values before operation begins. The device ID reader measures the resistance of the connected microwave instrument, and the generator controller compares this measured resistance with stored resistance value indicators to identify the device type in advance, allowing the system to automatically configure appropriate operating thresholds before the ablation procedure starts
Solution Approach 2:
The system uses feedback from the measured resistance value to automatically determine the device type and configure appropriate operating parameters. The device ID reader provides feedback about the connected device's electrical characteristics, and the generator controller uses this feedback to automatically select and apply the correct operating configuration, eliminating manual setup time
3Reliability
If the microwave generator uses generic operating thresholds, then the system is simple to manufacture, but it cannot ensure safety for all device types
Solution Approach 1:
The system performs preliminary device identification by measuring resistance values before operation begins. The device ID reader measures the resistance of the connected microwave instrument, and the generator controller compares this measured resistance with stored resistance value indicators to identify the device type in advance, allowing the system to automatically configure appropriate operating thresholds before the ablation procedure starts
Solution Approach 2:
The system applies different operating thresholds tailored to each specific device type. By measuring the resistance and identifying the device type, the generator controller selects device-specific operating parameters including maximum power settings, maximum treatment time, and maximum device temperature thresholds, ensuring each device operates within its safe limits rather than using universal generic thresholds
4Adaptability or versatility
If the microwave generator measures device resistance, then it can identify device type, but it requires additional monitoring hardware
Solution Approach 1:
The device ID reader serves multiple functions: it measures the resistance of the connected microwave instrument to identify device type, and this same measurement capability is used to verify device compatibility and ensure safe operation. By making the resistance measurement function multi-purpose, the system avoids adding separate dedicated hardware for each function, thereby reducing overall hardware complexity while maintaining device identification capability
