Computer System Booting Method with Dynamic Transmission Specification Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In conventional computer systems, signal attenuation between the mainboard and graphics card often results in no display, requiring complex user interventions such as changing connection methods or modifying BIOS settings, which are difficult to perform when the display is failing.
Innovation Solution
A booting method that includes a transmission interface connected to the graphics card, a power key, and a trigger element, where the system detects the trigger element's activation and lowers the transmission specification to restart the computer, simplifying the debugging process by allowing users to display the graphics card normally.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the transmission specification is lowered to resolve signal attenuation, then the display stability is improved, but the transmission speed deteriorates
Solution Approach 1:
The transmission specification is made dynamically adjustable based on detection results. The system automatically switches between different transmission specifications (e.g., PCIe 3.0, 2.0, 1.0) depending on whether signal attenuation is detected, allowing the transmission interface to adapt its performance characteristics to current connection conditions rather than being fixed at a single high-speed mode
Solution Approach 2:
The transmission specification parameter is changed from a fixed high-speed setting to a variable setting that can be adjusted between different speed levels. When signal attenuation is detected, the system changes the transmission specification parameter to a lower level, thereby improving signal stability while accepting reduced transmission speed
2Reliability
If the user enters BIOS to modify graphics card settings, then the display issue is resolved, but the operation complexity increases
Solution Approach 1:
The system performs automatic detection and adjustment of transmission specifications without requiring user intervention. The mainboard automatically detects signal attenuation issues and adjusts the transmission specification accordingly, eliminating the need for users to manually enter BIOS and modify settings
Solution Approach 2:
The system implements a feedback mechanism where the transmission interface monitors signal quality during the booting procedure, and based on this feedback, automatically adjusts the transmission specification. This closed-loop control allows the system to self-correct display issues without user involvement
3Reliability
If the connection interface is made more stable, then signal attenuation is reduced, but the device complexity increases
Solution Approach 1:
The system performs preliminary detection of signal attenuation during the booting procedure before the operating system fully loads. By detecting and adjusting transmission specifications early in the boot process, the system prevents display issues from occurring in the first place, rather than requiring complex troubleshooting procedures later
