Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple physiological and environmental sensors are integrated into the in-ear wearable device, then the monitoring capability and data accuracy are improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent integrates multiple physiological sensors (accelerometer, gyroscope, pulse oximetry, temperature, ECG, EMG, EEG, GSR) and environmental sensors (barometer, gas sensor, radiation sensor) into a single in-ear wearable device housing, combining multiple measurement functions into one compact unit to improve comprehensive monitoring capability while managing device complexity
Solution Approach 2:
The in-ear wearable device is designed as a multi-functional platform that simultaneously performs physiological monitoring, environmental sensing, data processing, and wireless communication, allowing a single device to execute multiple functions that would otherwise require separate systems
2Loss of time
If real-time data transmission to centralized computer is implemented, then the situational awareness and response time are improved, but the energy consumption increases
Solution Approach 1:
The controller transmits physiological parameters and environmental conditions to the centralized computer periodically or at predetermined intervals, rather than continuously, which reduces energy consumption while still providing timely updates for situational awareness and rapid response when needed
Solution Approach 2:
The system implements a feedback loop where the controller receives sensor data, processes it locally, and transmits only relevant information to the centralized computer, which then provides feedback for monitoring and alert generation, optimizing energy usage by avoiding unnecessary continuous transmission
