Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If separate devices are used for monitoring cardiac conditions and blood oxygen saturation levels, then device complexity is reduced, but monitoring comprehensiveness deteriorates
Solution Approach 1:
The patent combines multiple monitoring functions (cardiac rhythm monitoring via ECG electrodes and blood oxygen saturation monitoring via pulse oximetry sensor) into a single wearable medical device. The support structure integrates both the monitoring component for cardiac activity and the oxygenation sensor, allowing simultaneous comprehensive monitoring of multiple vital signs without requiring separate devices.
2Measurement precision
If active user intervention is required for measurements, then measurement precision can be ensured, but ease of operation deteriorates
Solution Approach 1:
The wearable medical device performs automatic continuous monitoring of cardiac and oxygenation parameters without requiring active user intervention. The monitoring component continuously captures ECG signals and the oxygenation sensor continuously measures blood oxygen saturation levels, with the processor automatically analyzing the data. This enables passive measurement while maintaining precision through continuous automated sensing.
3Reliability
If continuous monitoring is implemented, then reliability of health monitoring is improved, but use of energy deteriorates
Solution Approach 1:
The device implements continuous monitoring of cardiac and oxygenation parameters through continuously operating sensors and processing. The monitoring component continuously records ECG data and the oxygenation sensor continuously measures SpO2 levels, providing uninterrupted health monitoring data that enhances reliability for detecting arrhythmias and oxygenation changes.
