Engineering Contradiction Analysis
1Reliability
If regulated voltage outputs are optimized for maximum power configurations, then power requirements are met for wide range of configurations, but voltage precision and efficiency deteriorate for lower power configurations
Solution Approach 1:
The patent implements dynamic adjustment of voltage regulator output points based on detected system configuration and power requirements. The system transitions from static voltage optimization for maximum power to dynamic optimization that adapts to actual power needs, thereby maintaining voltage precision across varying configurations while ensuring power requirements are met.
Solution Approach 2:
The system changes the operating parameters of voltage regulators by adjusting output voltage points based on detected configuration. Instead of using fixed voltage settings, the system modifies regulator parameters dynamically to match actual power requirements, resolving the contradiction between meeting power requirements and maintaining voltage precision.
2Stability of the object's composition
If voltage regulators are adjusted for maximum power configurations, then power stability is ensured, but energy efficiency deteriorates in lower power configurations
Solution Approach 1:
The system dynamically adjusts voltage regulator settings based on detected configuration and power requirements. By transitioning from static maximum-power optimization to dynamic adaptation, the system maintains power stability through active monitoring and adjustment while improving energy efficiency by avoiding excessive voltage output in lower power configurations.
Solution Approach 2:
The system performs self-adjustment by detecting its own configuration and automatically modifying voltage regulator output points. This self-service capability enables the system to optimize energy efficiency while maintaining power stability without external intervention, adapting to actual power needs in real-time.
3Device complexity
If fixed target voltage points are used, then system simplicity is maintained, but adaptability to different configurations deteriorates
Solution Approach 1:
The patent introduces dynamic adjustment capability to voltage regulators, transitioning from fixed target voltage points to dynamically determined output points. The system detects configuration and calculates appropriate voltage settings, thereby achieving configuration adaptability while maintaining relative simplicity through automated control logic.
Solution Approach 2:
The system implements feedback by detecting actual configuration and power requirements, then using this information to adjust voltage regulator output points. This feedback mechanism enables adaptability to different configurations while maintaining system simplicity through closed-loop control that automatically compensates for configuration variations.

AI summary
A device includes a plurality of voltage regulators, and a test module. Each of the voltage regulators are configured to provide a regulated voltage to one of a plurality of subsystems. The test module is in communication with the voltage regulators, and is configured to perform a subsystem component inventory for each of the subsystems at a start of a power-on self-test of the device, to determine a configuration of the device. The test module is also configured to capture first voltage data for the subsystems during an idle operation, to capture second voltage data for the subsystems during a stressed operation, and to set a voltage set point for each of the regulated voltages provided by one of the voltage regulators based on the subsystem component inventory, a power requirement table, or the first and second voltage data.
