Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the object detection system is always switched on to improve detection accuracy through repeated measurements, then detection accuracy is improved, but battery discharge occurs due to high operating current
Solution Approach 1:
The patent implements dynamic control of sensor operation modes based on real-time environmental conditions. The controller switches between active detection mode (high accuracy, high power consumption) and standby mode (low accuracy, low power consumption) according to temperature and illuminance thresholds, resolving the contradiction between continuous high-accuracy detection and battery conservation
Solution Approach 2:
The system changes operational parameters (sensor activation state, detection frequency) based on environmental parameters (temperature, illuminance). By adjusting these parameters dynamically rather than maintaining fixed high-performance settings, the system achieves adequate detection accuracy while reducing energy consumption during unfavorable conditions
2Reliability
If the sensor operates continuously under fixed absolute conditions to ensure detection reliability, then detection reliability is improved, but system efficiency degrades due to unnecessary operations
Solution Approach 1:
The patent transitions from static fixed-threshold control to dynamic adaptive control. The sensor operation conditions are adjusted in real-time based on environmental feedback, allowing the system to maintain reliable detection when conditions favor detection while improving efficiency by reducing operations when environmental conditions are unfavorable
Solution Approach 2:
The system incorporates environmental feedback loops where temperature and illuminance sensors continuously monitor conditions and feed this information to the controller. This feedback mechanism enables the system to adapt sensor operation and alarm conditions dynamically, improving both reliability and efficiency by making detection efforts contingent on favorable environmental conditions
3Ease of operation
If the alarm operates under the same preset conditions for all situations to simplify control logic, then control simplicity is maintained, but alarm efficiency degrades in less dangerous or very dangerous situations
Solution Approach 1:
The patent applies different alarm conditions and sensor operation parameters to different environmental conditions and risk levels. Instead of uniform control, the system tailors alarm behavior (activation thresholds, duration, intensity) to the specific situation, improving alarm efficiency while maintaining manageable control through automated environmental assessment
Solution Approach 2:
The alarm system transitions from static uniform response to dynamic differentiated response. Alarm conditions are adjusted based on environmental conditions and determined risk levels, allowing the system to provide appropriate alarm intensity and activation criteria for less dangerous, normal, and very dangerous situations
