Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the trigger signal is transmitted through the host for decoding and processing, then the host can process the signal, but the response delay increases
Solution Approach 1:
The patent segments the signal processing path into two independent channels: a fast path that directly captures trigger signals from the input device to the display panel, and a normal path that routes signals through the host for non-time-critical operations. This segmentation allows delay-sensitive commands to bypass the host decoding process, reducing response delay while maintaining system functionality.
Solution Approach 2:
The control device acts as an intermediary between the input device and the display panel. It intercepts trigger signals from the input device, captures them through the signal capture unit, and directly transmits them to the display panel without requiring host processing. This intermediary role enables the system to reduce response delay for critical commands while the host continues to handle other processing tasks.
2Speed
If the control device captures and processes trigger signals directly, then the response time improves, but the device complexity increases
Solution Approach 1:
The patent merges the signal transmission function and signal capture function into a single control device. The connector unit handles signal transmission to the host, while the signal capture unit simultaneously captures trigger signals for direct processing. By combining these functions in one device, the patent achieves fast signal processing without requiring separate independent systems, thereby limiting the increase in overall device complexity.
Solution Approach 2:
The signal capture unit is configured to capture trigger signals in advance before they are processed by the host. This preliminary action allows the control device to prepare and transmit captured signals to the display panel immediately, improving signal processing speed. The capture operation is performed proactively, enabling the system to respond faster to user inputs without waiting for host processing to complete.
