Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If thermal and radar sensors are used to detect health conditions in real-time, then safety and responsiveness are improved, but device complexity increases
Solution Approach 1:
The patent combines thermal sensors and radar sensors into a hybrid sensing system. The thermal sensor captures thermal radiation from the human body to detect health conditions, while the radar sensor simultaneously measures motion and physiological parameters. By merging these two sensing modalities, the system achieves reliable real-time health monitoring through multiple complementary measurement mechanisms, resolving the contradiction between detection reliability and system complexity.
Solution Approach 2:
The hybrid sensing system is designed to perform multiple functions: thermal imaging for health condition detection, radar-based motion tracking, and physiological parameter measurement. This multi-functionality allows a single integrated system to address various health monitoring needs simultaneously, improving reliability without requiring separate dedicated systems for each function.
2Measurement precision
If multiple biometric features are monitored simultaneously, then hazard prediction accuracy is improved, but data processing complexity increases
Solution Approach 1:
The patent segments the complex data processing task into distinct modules: thermal signal processing extracts health condition information, radar signal processing extracts motion and physiological parameters, and a separate analysis module integrates these data streams to generate hazard predictions. This segmentation allows each module to specialize in specific processing tasks, improving overall prediction accuracy while managing complexity through modular architecture.
Solution Approach 2:
The system introduces an intermediary processing layer that receives raw signals from both thermal and radar sensors, performs initial feature extraction and filtering, then passes processed information to the hazard prediction algorithm. This intermediary layer simplifies the complexity by pre-processing and organizing multi-source data before final analysis, enabling accurate hazard prediction without overwhelming computational burden.

AI summary
Apparatuses and methods detect a health condition of a user that may be assessed from a thermal sensor signal and/or radar sensor signal. One or more resultant biometric vectors may be generated from biometric vectors based on the thermal and radar signals, where the resultant biometric vectors contain resultant information about one or more biometric features for a user. Hazard information about the user is obtained from the one or more resultant biometric vectors, where the hazard information is indicative of a health event for the user. Consequently, an appropriate action on behalf of the user may be performed to ameliorate the health condition. The one or more resultant biometric vectors may include additional biometric features and/or a time sequence of the resultant biometric vectors to enhance hazard prediction. Moreover, the apparatuses and methods may support the user in different settings including a home, business, or vehicle.
