Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple small-sized display devices are used to stitch a large-sized image, then the cost is reduced and failure rate is lowered, but the video signal source does not have sufficient output terminals to drive the required amount of display devices
Solution Approach 1:
The video signal source is segmented into multiple independent output terminals, each capable of driving a separate display device. This allows the system to output video signals to multiple display devices simultaneously, enabling stitched display configurations without requiring a single complex high-capability output interface.
Solution Approach 2:
The video signal source is designed with multi-functional output capabilities, where a single device can drive multiple display devices through multiple output terminals. This universal output capability allows the same video signal source to adapt to various stitched display configurations using different numbers and arrangements of display devices.
2Reliability
If multiple small-sized display devices are used to stitch a large-sized image, then the cost is reduced and failure rate is lowered, but the transmission interface of the video signal source may not be compatible with some small-sized display devices
Solution Approach 1:
The video signal source incorporates multiple output terminals with different interface types (e.g., HDMI, DisplayPort, DVI) to ensure compatibility with various small-sized display devices. This multi-interface capability allows the system to adapt to different display devices without requiring separate video signal sources for each device type.
Solution Approach 2:
The video signal source can dynamically change its output parameters including interface type, resolution, and refresh rate to match the capabilities of connected display devices. This parameter adaptation ensures optimal compatibility and performance across different display device models and specifications.
3Adaptability or versatility
If a single large-resolution image is generated and then sliced into multiple sub-images, then the stitched image can be optimized according to display device positioning, but the processing complexity increases
Solution Approach 1:
The system performs preliminary actions by first determining the positioning and arrangement of display devices, then pre-calculating the optimal stitching parameters and image slicing configuration before actual image generation. This preliminary planning reduces processing complexity during real-time operation by establishing the slicing scheme in advance based on detected display device positions.
Solution Approach 2:
The system incorporates feedback mechanisms that detect the actual positioning of display devices and automatically adjust the image slicing and stitching parameters accordingly. This closed-loop control allows the system to optimize the stitched image based on real device positions while maintaining manageable processing complexity through automated adaptation.
