Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple video cameras and intelligent video capturing means are used to improve video quality and coverage, then the video production quality and event coverage are improved, but the system complexity and hardware costs increase
Solution Approach 1:
The system divides the video capture task into two segments: an overview camera capturing the entire target field and additional cameras capturing specific subareas. This segmentation allows the system to achieve comprehensive coverage without requiring a complex array of cameras, as each camera has a focused, simplified function.
Solution Approach 2:
The overview camera serves as an intermediary that captures interest level information about the entire field. This intermediary device enables the system to determine which subareas require additional camera coverage, thereby reducing the total number of cameras needed while maintaining high production quality.
2Adaptability or versatility
If multiple video cameras are deployed to cover different sections of events, then the event coverage and viewing experience are improved, but the hardware costs and system complexity increase significantly
Solution Approach 1:
The system segments the field of view into a main overview area and multiple subareas. The overview camera provides comprehensive coverage of the entire field, while additional cameras are strategically positioned to capture only the most interesting subareas, thereby achieving versatile event coverage with minimal hardware.
Solution Approach 2:
The overview camera automatically identifies interesting events and subareas through image processing algorithms. This self-service capability eliminates the need for manual camera operation and selection, allowing the system to achieve comprehensive event coverage autonomously with fewer cameras.
3Manufacturing precision
If skilled professionals operate multiple video cameras for synchronized recording, then the video production quality is improved, but the operational complexity and cost increase
Solution Approach 1:
The system employs automated image processing algorithms that analyze the overview video recording to identify interesting events and automatically select corresponding video contents from additional cameras. This self-service automation eliminates the need for skilled professionals to manually operate multiple cameras and achieve synchronization, greatly simplifying operation while maintaining high production quality.
Solution Approach 2:
The patent replaces the mechanical system of manual camera operation and synchronization with an automated computational system. Image processing algorithms and automated selection mechanisms substitute for human operators, achieving precise video synchronization without requiring skilled professionals.
4Loss of information
If extensive camera coverage is provided to capture all event details, then no event details are overlooked, but the bandwidth usage and system complexity increase
Solution Approach 1:
The system extracts only the most relevant video contents from the overview recording and additional camera feeds based on automatically determined interest levels. By taking out and transmitting only these selected high-interest segments, the system preserves all important event details while significantly reducing bandwidth consumption compared to transmitting all camera feeds simultaneously.
Solution Approach 2:
The system dynamically changes the parameter of video content selection based on interest levels. Video contents are selected and transmitted only when their associated interest level exceeds a threshold, thereby preserving critical event details while optimizing bandwidth usage by excluding low-interest segments.
