Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric power control methods for electronic devices, such as portable computers, do not effectively manage power consumption based on the device's operational load, leading to unnecessary minimization of CPU performance.
Innovation Solution
An electric power control device and method that monitor power consumption, calculate moving averages, determine operational loads, and switch between restriction and restriction release modes to optimize power usage by imposing or releasing upper limits on source power or CPU frequency based on load zones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If power consumption is minimized based on battery information and supplied power, then power consumption is reduced, but CPU performance is not demonstrated adequately
Solution Approach 1:
The patent applies dynamics by making the power control system adaptive and responsive to real-time CPU load conditions. The control section dynamically switches between restriction mode and restriction release mode based on monitored power consumption and calculated moving averages, allowing the system to optimize between power savings and performance based on actual operational needs rather than static battery information alone.
Solution Approach 2:
The patent implements feedback by continuously monitoring power consumption, calculating moving averages, and using this information to determine CPU load states. The control section uses this feedback loop to adjust power restriction levels, ensuring that power consumption is minimized only when appropriate while maintaining CPU performance when needed based on actual load conditions.
2Use of energy by moving object
If upper limit of source power or CPU frequency is imposed based on battery information, then power consumption is reduced, but CPU performance is unnecessarily restricted
Solution Approach 1:
The system dynamically adjusts power restriction levels based on real-time CPU load monitoring. The control section switches between restriction mode and restriction release mode according to the determined load state, allowing the CPU to operate with full flexibility when load requires it while imposing restrictions only when power conservation is appropriate.
Solution Approach 2:
The patent changes the parameter of power restriction level based on CPU load state. By calculating moving averages of power consumption and comparing them against thresholds, the system adjusts the upper limit of source power or CPU frequency to match actual operational requirements, avoiding unnecessary restrictions.
3Productivity
If moving average calculation and load state determination are implemented, then optimal power control according to actual load is achieved, but device complexity increases
Solution Approach 1:
The patent applies self-service by implementing automated monitoring and control mechanisms that operate independently. The control section automatically monitors power consumption, calculates moving averages, determines load states, and adjusts power restriction levels without requiring manual intervention, thereby achieving optimal power control while managing complexity through automation.
Solution Approach 2:
The patent replaces complex mechanical or manual power control mechanisms with electronic monitoring and software-based control. By using a control section that processes electrical signals and executes control logic, the system achieves sophisticated power optimization without the complexity of mechanical adjustment mechanisms.

AI summary
An electric power control device includes: a power consumption monitoring section for monitoring electric power consumed by an electronic device; a moving average calculation section for calculating a moving average of the power consumption of the electronic device, based on the power consumption monitored by the power consumption monitoring section; a state-of-load determination section for determining state of the operational load on the electronic device, based on the moving average calculated by the moving average calculation section; and a control section configured to control the electronic device to operate either in a restriction mode in which an upper limit corresponding to state of load determined by the state-of-load determination section is imposed, or in a restriction release mode in which the upper limit is not imposed.
