Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power consumption adjustment methods in computing devices fail to balance power consumption effectively, leading to unbalanced use of electric power resources due to limited impact of output power consumption detection on the device's power supply system.
Innovation Solution
A power consumption adjustment method that determines the power consumption state of a power supply system and load state of components based on monitoring parameters, adjusting power consumption by detecting both primary and secondary power supplies to balance electric power resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If power consumption is adjusted by detecting output power consumption of power supply module only, then the detection is simple, but the impact on power supply system is limited and power consumption cannot be balanced effectively
Solution Approach 1:
The power supply detection is segmented into two independent parts: primary power supply detection (via power supply module output power) and secondary power supply detection (via component input power). This segmentation allows comprehensive power consumption monitoring while maintaining modular detection architecture, resolving the contradiction between detection completeness and system complexity.
Solution Approach 2:
The detection system uses a nested structure where the primary power supply detection is embedded within the overall power management system, and secondary power supply detection is nested within the component monitoring layer. This nested architecture enables multi-level power consumption analysis without proportionally increasing system complexity.
2Loss of energy
If power consumption adjustment is based on limited output power consumption detection, then the control strategy is simple, but the power consumption balancing effect is poor
Solution Approach 1:
The system implements dual-loop feedback control: primary feedback from power supply module output power and secondary feedback from component input power. This multi-source feedback mechanism enables more accurate power consumption assessment and more effective adjustment control, resolving the contradiction between control simplicity and adjustment effectiveness.
Solution Approach 2:
The system monitors and adjusts multiple power-related parameters simultaneously (output power, input power, voltage, current) to achieve comprehensive power consumption balancing. By changing and monitoring multiple parameters rather than relying on a single parameter, the system achieves better power resource balance and adjustment effectiveness.
3Measurement precision
If only single power supply detection is used, then the monitoring process is simple, but the power consumption state cannot be comprehensively determined
Solution Approach 1:
The detection process is divided into two independent detection stages: primary detection of power supply module output and secondary detection of component input. This segmentation enables comprehensive power state measurement while keeping each detection stage relatively simple and manageable.
Solution Approach 2:
The detection system is designed with multi-functionality to handle both primary power supply monitoring and secondary component power monitoring through a unified detection framework. This universal detection approach enables comprehensive measurement without requiring entirely separate detection systems, thus not significantly increasing detection difficulty.
