Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual regulation of oxygen flow is used, then the system is simple to operate, but the reliability of oxygen delivery is poor and inappropriate oxygen levels may cause irreversible organ damage
Solution Approach 1:
The system automatically monitors patient parameters (SpO2, heart rate, respiratory rate) and self-adjusts oxygen flow rates without requiring continuous manual intervention. The microprocessor-controlled pump autonomously regulates gas delivery based on real-time physiological data, eliminating the need for constant nursing supervision while maintaining reliable oxygen delivery.
Solution Approach 2:
The system implements closed-loop feedback by continuously monitoring patient physiological parameters and using this information to automatically adjust oxygen therapy. The microprocessor receives real-time data from sensors, compares current status against target ranges, and dynamically modifies pump output to maintain optimal oxygen saturation levels.
2Productivity
If manual supervision of multiple patients is performed, then the system requires minimal automation, but the time consumption increases and nursing staff are overwhelmed
Solution Approach 1:
The oxygen therapy system performs self-monitoring and self-regulation of multiple patients simultaneously, freeing nursing staff from routine supervision tasks. The automated system handles continuous parameter monitoring, alarm management, and therapy adjustment for each patient independently, dramatically improving nursing productivity.
Solution Approach 2:
The system is designed to universally monitor and control oxygen therapy for multiple patients with different clinical conditions through a single integrated platform. The microprocessor-controlled pump can be configured for various patient types and automatically adapts its monitoring and control algorithms to each individual's needs.
3Measurement precision
If general alarm ranges are used for all patients, then the alarm system is simple to configure, but the measurement precision for individual patient needs deteriorates
Solution Approach 1:
The system implements patient-specific alarm thresholds and target saturation ranges tailored to each individual's clinical condition, age, and pathology. Instead of using universal alarm settings, the microprocessor configures customized monitoring parameters for each patient, ensuring precise and relevant alerts that reflect individual physiological needs.
Solution Approach 2:
The alarm system dynamically adjusts monitoring parameters and alert thresholds based on each patient's specific clinical condition and real-time physiological status. The system adapts target saturation ranges and alarm limits according to the patient's age, diagnosis, and current state, providing dynamic rather than static monitoring parameters.
4Reliability
If excessive oxygen is administered, then the oxygen saturation level is high, but harmful effects occur such as retinopathy of prematurity
Solution Approach 1:
The system uses real-time feedback from SpO2 sensors to automatically adjust oxygen delivery, preventing both hypoxia and hyperoxia. The microprocessor continuously monitors saturation levels and modulates pump output to maintain oxygen within a safe target range, avoiding the harmful effects of excessive oxygen administration while preventing inadequate oxygenation.
Solution Approach 2:
The system dynamically changes oxygen flow rate parameters based on real-time physiological feedback to maintain optimal saturation levels. By continuously adjusting the concentration and flow of administered oxygen according to measured SpO2 values, the system prevents parameter extremes that could cause harmful effects like retinopathy of prematurity.

AI summary
The Intelligent Automatic Oxygen Therapy System provides a device that allows the automatic and intelligent dosage of the percentage of an oxygen/air gas mixture and the flow delivered to each patient through non-invasive oxygen therapy procedures, based on the analysis of several measured variables that confirm the SpO2 value before taking any action. This device allows to measure biomedical signs with the main object of monitoring the oxygen saturation (SpO2), confirming its value with the analysis of the mentioned signs according to their concordance and interrelationship with each other. The equipment through artificial intelligence detects events that can occur due to the movement or for misplaced sensors. It also keeps and analyzes the records of the patient, evaluates the alarms in an intelligent way by correlating all acquired data; with this analysis the equipment can automatically and reliably provide the oxygen/air mixture adequate for each patient, with five operation modes. It activates the processed and valid alarms in an intelligent way and informs in a timely manner to the personal staff about possible found pathologies.
