Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous sensing and analysis of light beams is performed to maintain image quality and monitor subjects, then monitoring effectiveness is improved, but power consumption increases
Solution Approach 1:
The sensing assembly performs periodic sensing operations at predetermined intervals rather than continuous sensing. The processing circuit determines whether to perform sensing operations based on time intervals, enabling the system to balance monitoring effectiveness with power consumption by activating the sensing assembly only when necessary
Solution Approach 2:
The processing circuit autonomously determines whether sensing operations should be performed by evaluating multiple factors including time intervals, motion detection results, and abnormality indicators. This self-service mechanism eliminates the need for continuous external control signals, reducing power consumption while maintaining effective monitoring
2Reliability
If sensing assembly operates continuously to capture images and detect abnormalities, then monitoring reliability is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts the operating state of the sensing assembly based on real-time conditions. The processing circuit changes the operation mode between active sensing and standby states according to detected motion, time intervals, and abnormality indicators, optimizing the balance between monitoring reliability and energy consumption
Solution Approach 2:
The system changes operational parameters including the time interval between sensing operations, the state of the sensing assembly (active/standby), and the frequency of processing operations. These parameter changes are dynamically adjusted based on environmental conditions, motion detection results, and monitoring requirements to optimize both reliability and energy efficiency
3Measurement precision
If motion detection and abnormality identification are performed continuously, then detection accuracy is improved, but processing time and power consumption increase
Solution Approach 1:
The processing circuit uses feedback from motion detection results, time interval analysis, and abnormality indicators to determine whether to perform sensing operations. This feedback mechanism enables the system to concentrate processing resources when abnormalities are detected while reducing processing activity during normal conditions, improving detection accuracy without requiring continuous processing
Solution Approach 2:
The system performs preliminary motion detection and time interval analysis before initiating full sensing and processing operations. This preliminary action allows the system to identify potential abnormalities early and prepare for detailed analysis only when necessary, reducing overall processing time while maintaining detection accuracy
