Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automatic tracking technology is used to control the camera to track a specific object, then object tracking smoothness is improved, but image quality deteriorates during streaming
Solution Approach 1:
The patent applies dynamics by making the camera control parameters adjustable based on streaming status. The control apparatus dynamically changes pan/tilt driving speeds and zoom values according to whether the camera is in streaming mode or non-streaming mode, allowing optimal performance for each operational state without compromising the other
Solution Approach 2:
The patent changes control parameters (pan driving speed, tilt driving speed, zoom value) based on streaming status. During streaming, lower pan/tilt speeds are used to maintain image quality, while during non-streaming, higher speeds enable smoother tracking. The zoom value is also adjusted according to streaming status to optimize both tracking performance and image quality
2Manufacturing precision
If pan and tilt driving speeds are limited during streaming to prevent image quality deterioration, then image quality is maintained, but object tracking responsiveness deteriorates
Solution Approach 1:
The system dynamically adjusts pan and tilt driving speeds based on streaming status. During streaming, reduced speeds maintain image quality while still enabling tracking. During non-streaming periods, the system restores higher speeds to ensure responsive and smooth object tracking, resolving the contradiction between image quality and tracking responsiveness
Solution Approach 2:
The patent implements periodic adjustment of control parameters based on the streaming schedule. The control apparatus alternates between streaming-mode parameters (lower speeds for quality) and non-streaming-mode parameters (higher speeds for responsiveness), matching the periodic nature of streaming operations
3Measurement precision
If zoom value is increased during non-streaming to improve object tracking, then tracking precision is improved, but image quality deteriorates
Solution Approach 1:
The zoom value is dynamically adjusted based on streaming status. During non-streaming, higher zoom values improve tracking precision by providing a closer view of the tracked object. During streaming, the zoom value is reduced to maintain broader context and higher overall image quality, eliminating the need to choose between tracking precision and image quality
