Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single camera is used to monitor a wide area, then device complexity is reduced, but measurement precision of intrusion detection deteriorates
Solution Approach 1:
The monitoring area is divided into multiple sensing zones using multiple sensing devices, each covering a specific direction. This segmentation allows a single camera to focus on detected intrusions with higher precision while the overall wide area coverage is maintained through coordinated sensing zones.
Solution Approach 2:
Multiple sensing devices act as intermediaries between the single camera and the wide monitoring area. These sensors detect intrusions in their respective zones and trigger the camera to capture images only when intrusions are detected, enabling precise detection without requiring the camera to continuously scan the entire area.
2Reliability
If multiple sensing devices are deployed to cover wide areas, then detection capability is improved, but device complexity increases
Solution Approach 1:
Each sensing device is designed to perform multiple functions: detecting intrusions, determining its own spatial position, and identifying its sensing direction. This multi-functionality reduces the need for separate components and simplifies the overall system architecture while maintaining reliable detection capability across wide areas.
Solution Approach 2:
The system implements feedback mechanisms where sensing devices provide detection signals to the image processing device, which then controls the camera based on the sensed intrusion data. This feedback loop enables coordinated operation of multiple sensing devices with a single camera, managing system complexity through intelligent control.
3Area of stationary object
If the camera continuously captures images of the entire monitoring area, then detection coverage is improved, but image storage efficiency deteriorates
Solution Approach 1:
Sensing devices perform preliminary detection of intrusions before the camera captures images. By pre-identifying intrusions in specific sensing zones, the system avoids capturing unnecessary images of normal areas, thereby improving storage efficiency while maintaining comprehensive monitoring coverage through the coordinated sensing network.
Solution Approach 2:
Instead of continuously capturing the entire monitoring area, the camera performs partial action by capturing only the specific zones where intrusions are detected by the sensing devices. This selective imaging approach maintains adequate detection coverage while significantly reducing the volume of stored images.

AI summary
The present invention relates to a monitoring system using an auto-lift, a camera, and a sensing device capable of controlling, on the basis of a detection signal detected by the sensing device installed in a monitoring area, a capturing direction of the camera in a direction toward the sensing device that has output the detection signal, capturing intrusion or approach of an object to be sensed, and facilitating maintenance and repair of the camera. To achieve the above objective, the monitoring system using an auto-lift, a camera, and a sensing device includes a plurality of sensing devices configured to set a predetermined area as a sensing area, sense an object approaching within the sensing area, and output a detection signal of the sensed object, a capturing device having a camera that is lifted or lowered in response to a lifting/lowering control signal, a central control unit configured to receive the detection signal from the sensing device, adjust a capturing direction of the capturing device to capture the sensing area of the sensing device that has transmitted the detection signal, and store and manage an image captured by the capturing device, and an alert device configured to generate an alert sound or alert light in response to an alert signal output from the central control unit.
