Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If motion detector is used to detect movements, then movement detection capability is improved, but false alarms increase due to inability to differentiate relevant and irrelevant objects
Solution Approach 1:
The patent combines motion detector technology with program-technical motion detection and object classification capabilities. The evaluation module integrates multiple detection methods and classifies detected objects to distinguish between relevant and irrelevant movements, thereby maintaining high detection capability while reducing false alarms from irrelevant objects like animals or plants.
Solution Approach 2:
The system implements feedback through the evaluation module which continuously analyzes detected movements, classifies objects, and adjusts system responses accordingly. This feedback mechanism allows the camera device to learn from detection patterns and improve its ability to differentiate between relevant and irrelevant movements over time.
2Reliability
If camera operates continuously to capture image data, then surveillance coverage is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic action by activating the camera only when motion is detected by either the motion detector or program-technical motion detection, rather than operating continuously. This intermittent operation mode maintains effective surveillance coverage while significantly reducing power consumption during periods without detected movement.
Solution Approach 2:
The system performs preliminary action through the motion detection stage before activating the camera. The motion detector and program-technical detection serve as preliminary filters that prepare the system for camera activation only when necessary, optimizing the balance between surveillance coverage and energy usage.
3Illumination intensity
If lighting is activated continuously for effective surveillance, then image quality is improved, but energy consumption increases
Solution Approach 1:
The lighting system operates periodically based on motion detection events rather than continuously. When motion is detected, the lighting activates to provide adequate illumination for image capture, then deactivates when no movement is present, maintaining image quality during critical moments while minimizing overall energy consumption.
Solution Approach 2:
The lighting system exhibits dynamic behavior by adjusting its operational state based on real-time motion detection conditions. The lighting intensity and duration are dynamically controlled to provide sufficient illumination only when and where needed, optimizing the trade-off between image quality and energy consumption.
4Reliability
If both motion detector and program-technical motion detection are used, then detection reliability is improved, but device complexity increases
Solution Approach 1:
The patent merges motion detector technology with program-technical motion detection algorithms into an integrated evaluation module. This combination leverages the strengths of both approaches - the real-time responsiveness of hardware motion detectors and the analytical capabilities of software-based detection - to achieve enhanced detection reliability while managing system complexity through unified architecture.
