Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If multiple depth plane images and zoom control information are transmitted separately in a multi-focus display system, then the processing speed and transmission rate can be improved, but the accuracy and correctness of data transmission deteriorate due to timing errors and processing delays
Solution Approach 1:
The patent merges multiple depth plane images and their corresponding zoom control information into a single integrated data stream for transmission. This combining approach ensures that all data elements arrive simultaneously and maintain their temporal relationships, eliminating timing errors that occur when data is transmitted separately. The merged transmission preserves both processing efficiency and data accuracy.
Solution Approach 2:
The system performs preliminary merging and encoding of depth plane images with zoom control information before transmission. By preparing the integrated data structure in advance, the system ensures that all components are ready for simultaneous transmission, preventing timing mismatches and ensuring accurate reconstruction at the receiving end.
2Device complexity
If the transmission bandwidth is limited, then the device complexity is reduced, but the image smoothness and correctness deteriorate due to data loss and transmission errors
Solution Approach 1:
The patent segments the merged image data into distinct depth plane images and zoom control information components during the decoding process. This segmentation allows the receiver to separately process and apply each component with appropriate error handling, maintaining image correctness even when transmission bandwidth is limited. The segmented approach enables targeted error correction without requiring complex overall system redesign.
3Productivity
If the image generation unit processes data at high speed, then the productivity is improved, but the transmission timing accuracy deteriorates, causing abnormal display content
Solution Approach 1:
By merging all depth plane images and zoom control information into a single transmission unit, the system eliminates timing synchronization issues that arise from high-speed separate processing. The merged structure ensures that regardless of processing speed, all data elements maintain their relative temporal positions, preventing display abnormalities caused by timing mismatches.
