Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single control block processes video for multiple display types, then device complexity is reduced, but image quality consistency across different displays deteriorates
Solution Approach 1:
The video processing system is divided into a main control block and a sub control block. The main control block performs first processing for the first display device, while the sub control block performs second processing for the second display device. This segmentation allows each control block to be optimized for its specific display type, ensuring image quality consistency across different display technologies without requiring a single complex control block to handle all displays.
2Reliability
If redundant control blocks are implemented for failover capability, then system reliability improves, but device complexity increases
Solution Approach 1:
The sub control block is designed with multi-functionality: it can process video independently for the second display device, and also take over video processing for the first display device when the main control block fails. This universal design provides failover capability and continuous operation without requiring separate dedicated backup systems, thereby improving reliability while controlling device complexity.
3Manufacturing precision
If independent processing paths are created for different displays, then image quality consistency improves, but component count increases
Solution Approach 1:
The video processing paths for different display devices are merged at the transmission stage. The main control block transmits processed video to the first display device, while the sub control block transmits its processed video to the second display device. This merging approach allows independent processing optimization for each display type while sharing the overall system architecture and transmission infrastructure, thereby maintaining image quality consistency without excessively increasing component count.
4Manufacturing precision
If video processing is optimized for specific display types, then image quality improves, but adaptability to different displays deteriorates
Solution Approach 1:
The sub control block acts as an intermediary that receives the original video signal and performs second processing specifically optimized for the second display device. This intermediary approach allows the system to maintain specialized processing paths for different display types while still providing adaptability, as the sub control block can handle video for its designated display and the main control block can take over if needed, ensuring both image quality optimization and system versatility.
