Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high camera pixel counts and motion detection range are used, then measurement precision and detection capability are improved, but device complexity and cost increase
Solution Approach 1:
The system divides the surveillance function into two segments: a remote sensing device with high-resolution camera for precise measurement and detection, and a separate microcontroller-based motion detection system with lower resolution sensors for broad area monitoring. This segmentation allows each component to be optimized for its specific function, reducing overall system complexity while maintaining high measurement precision where needed.
2Reliability
If traditional remote monitoring hardware is used, then standalone operation is achieved, but power consumption increases
Solution Approach 1:
The system implements dynamic power management where the smartphone processor operates in low-power modes during standby and only activates fully when motion is detected by the microcontroller. The microcontroller continuously monitors for motion events at minimal power consumption, then dynamically wakes the higher-power smartphone processor to handle image processing and data transmission only when needed, achieving standalone operation with significantly reduced average power consumption.
3Area of stationary object
If multiple cameras are deployed to cover large areas, then detection coverage is improved, but device quantity and installation complexity increase
Solution Approach 1:
The remote sensing device is designed as a universal platform that can detect motion, capture high-resolution images, and transmit data across large areas. By combining a high-resolution camera with a wide-field motion detection sensor and implementing intelligent image processing that only captures frames when motion is detected in the periphery, a single device can effectively cover areas that would traditionally require multiple cameras, reducing installation complexity while maintaining comprehensive coverage.
