Power Management System Dynamic Element Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face power management challenges due to limited battery life and high thermal profiles from significant power draws, leading to reduced operational time and safety issues, even when powered by non-depletable sources.
Innovation Solution
A power management system that dynamically controls power-consuming elements based on prioritization and power draw limits, using a power management module and monitor to adjust operational parameters, such as turning off or reducing functions, to maintain power usage within predetermined limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If power-consuming elements operate at high power levels, then processing performance and functionality are improved, but battery life is reduced and thermal profiles increase
Solution Approach 1:
The system dynamically adjusts the operational state of power-consuming elements based on real-time power draw monitoring. The power management module continuously monitors power consumption and dynamically transitions elements between operational states (e.g., active, idle, sleep) to optimize the balance between performance and battery life, rather than using fixed power levels.
Solution Approach 2:
The system changes operational parameters of power-consuming elements (such as clock speed, voltage, or operational mode) based on monitored power draw conditions. When power draw approaches predetermined limits, the system modifies these parameters to reduce power consumption while maintaining acceptable performance levels.
2Productivity
If power-consuming elements operate at high power levels, then processing performance is improved, but thermal profiles and safety risks increase
Solution Approach 1:
The system dynamically responds to thermal conditions by continuously monitoring power draw and adjusting element operational states in real-time. When power draw (and thus thermal generation) approaches predetermined safety limits, the system dynamically transitions elements to lower-power states to maintain safe thermal profiles.
Solution Approach 2:
The power management module implements a feedback mechanism where power draw is continuously monitored and compared against predetermined limits. When limits are approached, the system provides feedback to adjust element operational states, creating a closed-loop control system that maintains safe thermal conditions.
3Duration of action of moving object
If power draw limits are enforced to extend battery life, then operational time is extended, but available functionality is reduced
Solution Approach 1:
The system dynamically manages the operational states of power-consuming elements based on real-time power draw conditions. Rather than permanently disabling elements, the system transitions them between active, idle, and sleep states, allowing functionality to be restored when power conditions permit, thus balancing operational time extension with functionality preservation.

AI summary
A power management system comprises a power management module configured to determine a power draw limit for operating an electronic device by a power source, the power management module configured to control use of power-consuming elements of the electronic device based on a prioritization of the power-consuming elements to limit a power draw by the electronic device from the power source to the power draw limit.
