Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If health monitoring systems use external monitoring centers for data analysis, then measurement precision can be improved, but loss of time increases due to delayed interventions
Solution Approach 1:
The patent extracts the data analysis function from external monitoring centers and embeds it directly into the wearable device's processor. This allows the system to perform real-time analysis of ECG and other physiological data locally, eliminating the time delay associated with external transmission and analysis while maintaining high detection accuracy through integrated algorithms.
Solution Approach 2:
The wearable system performs self-diagnosis and self-alerting through its integrated processor that automatically analyzes collected health data and issues alerts without requiring external professional intervention. The system serves itself by containing both sensing and analysis capabilities within the same device, enabling immediate response to detected hazards.
2Productivity
If sensors are integrated into garments for continuous monitoring, then productivity is improved by allowing normal daily activities, but measurement precision may deteriorate due to motion and displacement
Solution Approach 1:
The patent employs dynamic signal processing techniques that adapt to the user's motion state. The processor continuously adjusts filtering and analysis parameters based on detected movement levels, allowing accurate ECG measurement during both rest and activity. The system dynamically distinguishes between artifact signals from motion and actual cardiac events, maintaining precision throughout daily activities.
Solution Approach 2:
The garment integrates multiple sensors at specific strategic locations on the body to optimize signal quality in different regions. By placing electrodes and sensors at anatomically appropriate positions and using localized signal processing for each sensor group, the system maintains high measurement precision across various body positions and motion states while enabling continuous wear.
3Measurement precision
If multiple electrodes are used for clinical level ECG detection, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple ECG leads and sensor functions into a single integrated garment system. The processing unit consolidates data from multiple electrodes and sensors, performing combined analysis that achieves clinical-level diagnostic accuracy while presenting a unified, simplified user interface and single wearable device structure.
Solution Approach 2:
The wearable system incorporates multiple electrodes and sensors that serve multiple functions: ECG monitoring, arrhythmia detection, ischemia identification, and general physiological parameter measurement. This multi-functionality allows the same hardware configuration to achieve high measurement precision across various cardiac conditions without proportionally increasing device complexity.
