Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high-resolution camera video is used for remote state monitoring, then monitoring quality and detail visibility are improved, but bandwidth load and communication requirements increase significantly
Solution Approach 1:
The patent divides the monitoring system into two processing paths: full-resolution video processing for detailed analysis and downsampled video processing for general monitoring. This segmentation allows the system to maintain high monitoring quality when needed while reducing bandwidth load during normal operations by processing lower-resolution video streams.
Solution Approach 2:
The patent applies different quality levels to different monitoring scenarios by dynamically adjusting video resolution based on monitoring needs. High-resolution processing is applied locally to specific regions or events of interest, while other areas use lower resolution, thereby optimizing the balance between monitoring quality and bandwidth consumption.
2Loss of information
If high-resolution object images are stored, then detail information is preserved, but storage device load increases
Solution Approach 1:
The patent segments stored video data into different resolution levels and formats. Full-resolution frames are stored selectively for important events, while regular monitoring data is stored in downsampled format. This segmentation strategy preserves necessary detail information while significantly reducing overall storage device load.
Solution Approach 2:
Different storage quality levels are applied to different portions of the video data based on their importance. Critical events and regions of interest maintain high detail information, while routine monitoring data uses compressed lower-resolution storage, optimizing the balance between information preservation and storage efficiency.
3Area of stationary object
If a single monitoring camera covers a wide area, then monitoring coverage is improved, but video resolution and detail quality decrease
Solution Approach 1:
The patent segments the wide monitoring area into multiple virtual zones or regions of interest. Each zone can be independently processed at appropriate resolution levels, allowing the system to maintain wide coverage while preserving detail quality in specific areas by applying selective resolution processing to different segments of the monitoring field.
4Extent of automation
If the photographer sets the gaze area in advance, then automated monitoring is improved, but observer flexibility and dynamic adjustment capability are lost
Solution Approach 1:
The patent implements a dynamic gaze area setting mechanism where the observation region can be adjusted in real-time based on monitoring needs. The system transitions from static pre-configured gaze areas to dynamic, observer-controlled gaze areas that can adapt to changing monitoring requirements, thereby improving both automation and flexibility.
Solution Approach 2:
The patent incorporates feedback mechanisms that allow observers to monitor the current gaze area settings and adjust them based on real-time monitoring conditions. This feedback loop enables the system to maintain automated operation while responding adaptively to changing situations, balancing automation with observer flexibility.

AI summary
An automatic display system for a gaze area has a video input unit, an object detection unit and a gaze area setting unit that sets an area containing a part or the whole of the object detected by the object detection unit, or a predetermined area in the entire video as the gaze area. A control signal corresponding to the set gaze area information is received, and a gaze area acquisition unit acquires the gaze area from the entire video according to the control signal. A video output unit outputs a video of the acquired gaze area. The video input unit, a control signal receiving unit, and the gaze area acquisition unit are disposed in the input terminal; the gaze area setting unit and the video output unit are disposed in the output terminal; and information is transmitted between the input terminal and the output terminal by wireless communication.
