Engineering Contradiction Analysis
1Productivity
If CPU core clock and power density are increased to perform complex calculations, then calculation efficiency is improved, but instantaneous power consumption exceeds power supply bearing capability
Solution Approach 1:
The patent implements dynamic frequency adjustment of the CPU based on real-time power consumption monitoring. The power control module continuously monitors system power consumption and dynamically adjusts the CPU frequency to match the power supply unit's bearing capability, transforming the static CPU frequency into a dynamic parameter that adapts to power conditions.
Solution Approach 2:
The patent establishes a feedback control loop where the power control module monitors system power consumption and feeds this information back to adjust CPU frequency. The power supply unit's protection mechanism status and current power consumption levels are continuously fed back to the power control module, which then adjusts CPU operations accordingly to prevent power overload.
2Productivity
If CPU power consumption is increased to improve processing capability, then system performance is improved, but power supply protection mechanism is triggered causing system shutdown
Solution Approach 1:
The patent implements preliminary power management by detecting the power supply unit's rated power through the power connector before full system operation. The power control module pre-configures appropriate CPU frequency limits based on the detected rated power, preventing power overload conditions before they occur rather than reacting after shutdowns happen.
Solution Approach 2:
The patent changes the operating parameters of the CPU by adjusting its frequency based on the power supply unit's rated power and current system power consumption. This parameter adjustment ensures the CPU operates within safe power limits while maximizing performance, transforming the fixed CPU frequency into a variable parameter optimized for power conditions.
