Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual handling of carbon monoxide is used for hemoglobin determination, then the device complexity is reduced, but the measurement precision deteriorates due to inaccuracies in determining the administered carbon monoxide amount
Solution Approach 1:
The patent replaces manual mechanical handling of carbon monoxide with an automated electronic control system. The control unit automatically determines the administered carbon monoxide amount based on sensor measurements (pressure, temperature, volume), eliminating manual estimation errors and improving measurement precision while maintaining reasonable device complexity through integration.
Solution Approach 2:
The patent implements a feedback system where sensors continuously monitor the carbon monoxide reservoir parameters (pressure, temperature, volume) and provide real-time data to the control unit. This feedback loop enables automatic adjustment and precise determination of the administered carbon monoxide amount, resolving the contradiction between simplicity and precision.
2Ease of operation
If manual handling of carbon monoxide is used, then the ease of operation is improved, but the reliability deteriorates due to potential waste and exposure risks
Solution Approach 1:
The system performs self-monitoring and self-regulation of carbon monoxide administration. The sensors and control unit automatically track and control the carbon monoxide amount, ensuring safe operation and preventing waste or exposure risks without requiring constant manual intervention, thus maintaining ease of operation while improving reliability.
Solution Approach 2:
The patent replaces unreliable manual handling with an automated electronic control system that precisely manages carbon monoxide administration, eliminating human error and safety risks while maintaining user-friendly operation through automated processes.
3Measurement precision
If precise control over carbon monoxide administration is implemented with sensors and control systems, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The control unit serves multiple functions: it processes sensor data from pressure, temperature, and volume sensors; calculates the administered carbon monoxide amount; controls the breathing mixture generation; and monitors safety parameters. This multi-functionality reduces the need for separate dedicated components, improving measurement precision while limiting the increase in device complexity.
4Ease of operation
If manual handling of carbon monoxide is used, then the ease of operation is maintained, but the loss of substance increases due to potential waste of carbon monoxide
Solution Approach 1:
The feedback system continuously monitors the carbon monoxide reservoir parameters and provides real-time information to the control unit, enabling precise control of carbon monoxide administration. This prevents both waste from over-administration and insufficient dosing, reducing substance loss while maintaining ease of operation through automated management.
Solution Approach 2:
The system automatically tracks and regulates carbon monoxide usage, ensuring optimal utilization and preventing waste. The self-monitoring and self-regulation capabilities reduce substance loss without requiring additional manual effort from the operator.
