Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a generic system for driving 8k4k liquid crystal displays is not available, then processing high-resolution video signals becomes challenging and complex, but developing such a system would enable effective processing of high-resolution signals
Solution Approach 1:
The patent divides the high-resolution image data into multiple sub-images or blocks that can be processed independently and in parallel. This segmentation approach reduces the complexity of processing the entire 8k4k image at once while maintaining the ability to achieve high-resolution output through recombination of processed sub-images
Solution Approach 2:
The patent employs a multi-level processing architecture where lower-resolution processing stages are nested within higher-resolution stages. The system first processes images at reduced resolutions, then progressively refines them to achieve the final 8k4k output, creating a nested processing structure that manages complexity effectively
2Ease of manufacture
If image data is processed without division, then processing is simpler, but display quality in border areas deteriorates
Solution Approach 1:
The patent divides the image into multiple sub-images or blocks and processes each segment independently with specific attention to border regions. This segmentation allows for specialized border processing techniques to be applied at segment boundaries, improving overall display quality while keeping individual segment processing relatively simple
Solution Approach 2:
The patent applies different processing techniques to different regions of the image, particularly enhancing border areas of subdivided segments. By focusing computational resources on border regions where quality degradation occurs, the system improves local quality without significantly increasing overall processing complexity
3Productivity
If RGB pixels are converted directly to YUV without interpolation, then processing is faster, but color accuracy deteriorates
Solution Approach 1:
The patent performs preliminary interpolation of missing RGB values before the RGB to YUV conversion process. By pre-calculating and filling in missing color information in the RGB domain, the subsequent conversion to YUV maintains better color accuracy without requiring complex interpolation during the conversion itself, thus preserving processing speed
4Manufacturing precision
If full-frame intermediate buffers are used, then image quality is maintained, but memory requirements increase
Solution Approach 1:
The patent uses segmented buffers corresponding to divided image blocks rather than full-frame intermediate buffers. Each buffer stores only the processed data for its corresponding image segment, dramatically reducing total memory requirements while maintaining image quality through proper reconstruction of the full image from processed segments
Solution Approach 2:
The patent processes and buffers only the necessary portions of the image at any given time rather than maintaining full-frame buffers for all intermediate stages. This partial processing approach maintains sufficient image quality for the intended application while significantly reducing memory consumption by avoiding redundant full-frame buffer allocations
