Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional sensors are used to detect life presence, then the system is simple and inexpensive, but the detection reliability is insufficient especially through materials and walls
Solution Approach 1:
The patent combines multiple sensor types (UWB radar sensor, temperature sensor, CO2 sensor) into an integrated monitoring system. The UWB radar sensor specifically detects life presence through materials and walls by measuring microwave signal reflections from breathing and heartbeat movements, while the temperature and CO2 sensors monitor environmental hazards. This multi-sensor integration resolves the contradiction by achieving high detection reliability through complementary sensor functions while maintaining reasonable system complexity through unified design.
Solution Approach 2:
The UWB radar sensor acts as an intermediary that detects life presence indirectly by measuring subtle movements (breathing and heartbeat) through microwave signal reflections, rather than requiring direct contact or line-of-sight detection. This intermediary approach enables reliable detection through materials and walls without requiring complex sensor arrays, thus resolving the contradiction between detection reliability and system complexity.
2Reliability
If the system continuously monitors environmental conditions, then the safety coverage is improved, but the energy consumption increases
Solution Approach 1:
The system implements periodic monitoring of environmental conditions (temperature, CO2 levels) and life presence detection through the UWB radar sensor. Rather than continuous high-power operation, the sensors periodically sample the environment and trigger alerts only when hazardous conditions are detected or life presence is confirmed absent. This periodic action maintains safety coverage while significantly reducing overall energy consumption compared to continuous monitoring.
Solution Approach 2:
The UWB radar sensor enables the system to self-monitor life presence and environmental conditions autonomously without requiring constant human intervention or high-power active scanning. The sensor passively detects breathing and heartbeat movements through reflected microwave signals, allowing the system to maintain reliable safety monitoring with minimal energy expenditure.
3Adaptability or versatility
If air conditioning systems are used to filter air, then the system is simple and already present, but the toxic gas filtration capability is insufficient
Solution Approach 1:
The CO2 sensor acts as an intermediary that specifically detects toxic gas levels and environmental hazards, complementing the air conditioning system's general air circulation function. The sensor provides reliable toxic gas detection capability that the air conditioning system lacks, enabling the system to adapt to safety monitoring requirements without replacing existing air conditioning infrastructure.
Solution Approach 2:
The monitoring system integrates multiple functions: life presence detection through UWB radar, temperature monitoring, CO2/toxic gas detection, and emergency alerting. This multi-functional system resolves the contradiction by providing specialized toxic gas detection capability while leveraging the existing air conditioning system's air circulation function, achieving both adaptability and reliability.
