Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If software is updated using traditional sequential transmission methods, then the system complexity remains low, but the update speed is slow
Solution Approach 1:
The patent divides the software file into multiple sub-files based on system resolution requirements. Each sub-file is transmitted separately through the display interface circuit, enabling parallel processing and significantly increasing the update speed while maintaining manageable system complexity through structured segmentation.
Solution Approach 2:
The patent utilizes the display interface circuit's parallel transmission capability to transfer data in a different dimensional space. By leveraging the display hardware's inherent parallel data bus, the system achieves faster software updates without requiring a completely new transmission architecture, thus improving speed with moderate complexity increase.
2Productivity
If files are divided into sub-files for parallel transmission, then the transmission speed increases, but the data processing complexity increases
Solution Approach 1:
The processing unit divides the original file into multiple sub-files based on system resolution. This segmentation enables parallel transmission through the display interface circuit, improving transmission efficiency. The segmentation is done in a way that maintains data integrity and simplifies reassembly at the receiving end.
Solution Approach 2:
The patent introduces identify data as an intermediary element between the file data and the transmission process. This identify data includes information about the file structure and resolution requirements, acting as a mediator that guides the segmentation and reassembly processes, thereby reducing the complexity of data handling while maintaining high transmission efficiency.
3Loss of time
If traditional sequential file transmission is used, then the system remains simple, but the update time is long
Solution Approach 1:
The processing unit performs preliminary actions by determining the file length and dividing it into sub-files before transmission begins. This preliminary processing enables the subsequent parallel transmission to proceed efficiently, significantly reducing update time. The display interface circuit is prepared in advance to receive and process the sub-files in parallel, minimizing overall transmission time.
Solution Approach 2:
The patent implements continuous parallel transmission of sub-files through the display interface circuit. Multiple sub-files are transmitted simultaneously in parallel, eliminating the sequential waiting time inherent in traditional methods. This continuous parallel processing maintains high transmission speed throughout the update process, significantly reducing the total update time while the system manages complexity through dedicated parallel transmission paths.
