Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple separate detection devices are used to measure different physiological parameters (breath, heartbeat, temperature, humidity, pressure, chemical composition), then measurement precision and reliability are improved, but device complexity and manufacturing costs increase significantly
Solution Approach 1:
The patent combines multiple detection functions (breath detection, heartbeat detection, temperature sensing, humidity sensing, pressure sensing, and chemical composition sensing) into a single integrated detection device. The transmitter module and receiver module share common circuitry, and multiple sensor types are integrated into one system, thereby reducing device complexity and manufacturing costs while maintaining measurement precision for all physiological parameters
Solution Approach 2:
The detection device is designed with multi-functionality to perform various physiological measurements simultaneously. The system can detect breath patterns, heartbeat signals, temperature, humidity, pressure, and chemical composition using a unified platform, eliminating the need for multiple separate devices and reducing overall system complexity
2Reliability
If multiple separate detection devices are deployed to monitor different physiological parameters, then detection reliability is improved, but manufacturing costs and ease of manufacture deteriorate
Solution Approach 1:
By merging multiple detection functions into a single device, the patent reduces manufacturing costs associated with producing, stocking, and deploying multiple separate devices. The integrated design allows for standardized manufacturing processes and reduces the overall bill of materials, while maintaining reliable detection across all physiological parameters through coordinated sensor operation
3Ease of operation
If traditional detection methods are used for physiological parameters, then ease of operation is maintained, but productivity and analysis efficiency deteriorate due to separate processing of multiple parameters
Solution Approach 1:
The computing module consolidates the processing of all physiological parameters (breath, heartbeat, temperature, humidity, pressure, chemical composition) into a single integrated processing unit. This unified approach improves productivity by enabling simultaneous analysis of all parameters rather than requiring separate processing steps, while maintaining ease of operation through a single device interface

AI summary
A detection device for detecting an object with a sensor includes a transmitter module, a receiver module, a processing module, and a computing module. The transmitter module transmits an RF (Radio Frequency) signal to the object. The receiver module receives a reflective signal from the object. The reflective signal includes a feature signal and a sense signal. The processing module converts the reflective signal into an integrated digital signal. The computing module determines the integrated digital signal into first digital information and second digital information. The first digital information corresponds to the feature signal. The second digital information corresponds to the sense signal.
