Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate devices are used for ECG and PPG measurements, then each device can be optimized for its specific function, but synchronization complexity and device management burden increase
Solution Approach 1:
The patent combines ECG and PPG sensors into a single wearable patch device, integrating multiple sensing functions into one unit. This merging eliminates the need for complex synchronization algorithms between separate devices while maintaining the specialized functionality of each sensor type, directly resolving the contradiction between measurement reliability and synchronization complexity
2Adaptability or versatility
If multiple separate devices are worn for comprehensive monitoring, then more physiological parameters can be measured, but user convenience and compliance decrease
Solution Approach 1:
The wearable patch is designed as a multi-functional device that simultaneously performs ECG, PPG, and other physiological measurements. By integrating multiple sensing capabilities into a single universal device, the patent enables comprehensive health monitoring while significantly improving user convenience and compliance compared to wearing multiple separate devices
3Extent of automation
If separate devices operate independently, then each device can function autonomously, but data consistency and synchronization accuracy deteriorate
Solution Approach 1:
By merging ECG and PPG sensors into a single integrated device with a shared clock system, the patent eliminates data synchronization issues inherent in independent devices. The unified architecture ensures that all sensors operate under a common time reference, guaranteeing precise temporal alignment of data streams while maintaining automated operation
