Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual configuration method is used, then users can control the configuration process, but the configuration process is time-consuming and labor-intensive
Solution Approach 1:
The system performs self-configuration by automatically detecting available CXL devices, calculating optimal connection paths, and configuring the host system without requiring manual user intervention. The configuration method autonomously completes the entire setup process based on computing configuration requirements.
Solution Approach 2:
The system pre-determines the target processor and CXL devices based on configuration requirements before actual configuration begins. By pre-calculating the shortest connection paths and identifying idle devices, the system prepares all necessary configuration parameters in advance, enabling rapid automated configuration.
2Manufacturing precision
If manual configuration method is used, then users can ensure accurate configuration, but technical expertise is required and configuration is labor-intensive
Solution Approach 1:
The patent replaces manual mechanical configuration operations with automated computational algorithms. The system uses path calculation algorithms and device detection mechanisms to automatically determine optimal configurations, substituting human expertise with computational intelligence that maintains accuracy while reducing complexity.
Solution Approach 2:
The system continuously detects the status of CXL devices and adjusts configuration decisions based on real-time feedback about device availability and connection status. This feedback mechanism ensures accurate configuration while simplifying the user's role to merely providing initial requirements.
3Productivity
If automated configuration method is implemented, then configuration efficiency is improved, but device selection and path determination complexity increases
Solution Approach 1:
The configuration process is segmented into distinct modular steps: device detection, path calculation, target device selection, and configuration execution. Each step handles a specific aspect of the complexity independently, making the overall automated system manageable and efficient while dividing the complex task into simpler sub-tasks.
