Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional resuscitation devices are used, then oxygen can be provided to patients, but the devices are bulky and complex to use, requiring multiple clinicians to operate
Solution Approach 1:
The device automatically controls the compression of the gas bag through an electronic motor driven by a microcontroller, eliminating the need for manual operation by clinicians. The system self-regulates the compression frequency and pressure based on programmed parameters, making it easy to use while reducing operational complexity.
Solution Approach 2:
The manual mechanical compression system is replaced with an electronic motor-driven compression mechanism. The microcontroller controls the motor to compress the gas bag at predetermined frequencies, substituting complex manual mechanical operations with automated electronic control.
2Reliability
If a clinician manually squeezes the gas bag, then oxygen can be delivered to the patient, but the oxygen delivery is inconsistent and may be inadequate or excessive
Solution Approach 1:
The device incorporates pressure sensors and flow meters that provide real-time feedback to the microcontroller about the oxygen delivery status. The system automatically adjusts compression parameters based on this feedback to maintain consistent and appropriate oxygen delivery, preventing both inadequate and excessive oxygenation.
Solution Approach 2:
The compression frequency and pressure are dynamically adjusted by the microcontroller based on real-time sensor data and programmed patient requirements. This dynamic control ensures consistent oxygen delivery tailored to individual patient needs, eliminating the inconsistency of manual operation.
3Reliability
If excessive oxygen is delivered to the patient, then the patient receives sufficient oxygenation, but gastric insufflation occurs causing harm
Solution Approach 1:
Pressure sensors monitor the pressure in the gas bag and the flow meter measures the actual oxygen flow to the patient. The microcontroller uses this feedback to prevent excessive compression that would cause gastric insufflation, while ensuring adequate oxygenation through precise control of compression parameters.
Solution Approach 2:
The device is programmed with safety limits and pressure thresholds before operation. The microcontroller prevents compression actions that would exceed safe pressure levels, providing beforehand protection against gastric insufflation while maintaining adequate oxygen delivery within safe parameters.
