Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If video data from CCTV systems is analyzed using complicated algorithms to detect abnormal situations, then measurement precision of risk detection is improved, but device complexity increases and response speed decreases
Solution Approach 1:
The system segments the risk detection function into multiple components: sensors detect specific physical parameters (motion, sound, light), CCTV captures visual data, and each component processes only its designated data type. This division eliminates the need for complex holistic video analysis algorithms while maintaining detection accuracy through coordinated multi-source monitoring.
Solution Approach 2:
The patent introduces communication modules and control modules as intermediaries between sensors/CCTV and the central processing system. These intermediaries perform preliminary data filtering and formatting, reducing the complexity of algorithms required at the central analysis stage while preserving detection precision through structured data transmission.
2Measurement precision
If complicated algorithms are used for abnormal situation analysis, then measurement precision is improved, but response speed deteriorates
Solution Approach 1:
Sensors perform preliminary detection of risk indicators (motion detection, sound level monitoring, light changes) before full analysis is required. This preliminary action filters out normal situations early in the process, allowing the system to respond quickly to genuine anomalies without requiring complex algorithms for every observed event.
Solution Approach 2:
The detection process is segmented into rapid sensor-based screening and slower detailed analysis. Sensors provide immediate detection of potential risks, enabling fast response to urgent situations while more complex video analysis is performed separately for verification and documentation purposes.
3Measurement precision
If position ID information is managed and integrated with sensor data, then position determination accuracy is improved, but device complexity increases
Solution Approach 1:
The control module serves multiple functions: it manages position ID information, coordinates sensor operations, processes detection data, and controls lighting responses. This multi-functionality consolidates what would otherwise require separate complex systems into a single integrated unit, improving position determination accuracy without proportionally increasing overall system complexity.
