Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of microcontrollers and devices is increased to support multiple functions, then the functionality and versatility of the image display device is improved, but the processing time and communication time between units increases
Solution Approach 1:
The patent applies preliminary action by pre-storing timing information for video signals from multiple input terminals in advance. When a signal input change is detected, the main microcomputer can immediately retrieve and use the pre-stored timing information without waiting for sub-microcomputers to provide it in real-time, significantly reducing processing time while maintaining support for multiple input functions
Solution Approach 2:
The patent extracts the timing information retrieval function from the real-time communication process between main and sub-microcomputers. By storing timing information in advance and extracting only the necessary data when needed, the system reduces communication overhead and processing time while maintaining full functionality
2Adaptability or versatility
If the number of microcontrollers and devices is increased to support multiple functions, then the versatility of the image display device is improved, but the communication time between units increases
Solution Approach 1:
Timing information is prepared and stored in advance in the system memory before it is needed. This preliminary action eliminates the need for time-consuming real-time communication between main and sub-microcomputers when signal inputs change, reducing communication time while maintaining support for multiple input functions
Solution Approach 2:
The system creates and stores copies of timing information for different video signals in advance. When a signal input changes, the main microcomputer can immediately access the copied timing information without requiring real-time data transmission, significantly reducing communication overhead
3Adaptability or versatility
If sub-microcomputers are configured to process video signals from multiple input terminals, then the functionality is improved, but the startup process time increases due to signal presence determination and terminal switching
Solution Approach 1:
The system performs preliminary detection and stores timing information for video signals from all input terminals during the startup phase. This allows the main microcomputer to immediately access timing information when signal inputs change, eliminating the need for time-consuming signal presence determination and terminal switching operations
Solution Approach 2:
The patent segments the startup process into two phases: a preliminary phase where timing information is detected and stored for all input terminals, and an operational phase where the main microcomputer quickly retrieves pre-stored information. This segmentation reduces the perceived startup time during normal operation by preparing data in advance
