Power Management System for Battery Duration Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices powered by depletable power sources, such as batteries, face limitations in providing power for extended periods, necessitating a solution to manage power consumption effectively to extend usage time.
Innovation Solution
A power management system that dynamically controls power-consuming elements based on user-defined prioritization and estimated battery duration, adjusting operational parameters to ensure the device operates for a desired time by turning off or reducing low and medium priority functions before high priority ones, using a power management module and power monitor to analyze and adjust power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the device operates all power-consuming functions simultaneously, then functionality and user experience are improved, but battery duration deteriorates
Solution Approach 1:
The patent segments power-consuming functions into different priority levels (high, medium, low) and controls them independently based on battery status. The power management module divides the application set into priority groups and selectively activates or suspends applications based on available battery duration, thus maintaining essential functionality while extending battery life.
Solution Approach 2:
The system dynamically adjusts the operational state of applications based on real-time battery duration estimates. When battery duration is sufficient, more applications run simultaneously; when battery duration is limited, the system dynamically suspends lower-priority applications. This dynamic adaptation allows the device to optimize between functionality and battery duration based on current power availability.
2Duration of action of moving object
If the device suspends low-priority applications to extend battery life, then battery duration is improved, but user convenience deteriorates
Solution Approach 1:
The power management module continuously monitors battery status and provides feedback to both the system and user. It estimates battery duration based on current power consumption and notifies users when battery duration is limited. The system also allows users to view which applications are suspended and provides options to resume them, creating a feedback loop that maintains user awareness and control.
Solution Approach 2:
The system automatically manages application suspension and resumption without requiring direct user intervention. When battery duration is limited, the power management module autonomously identifies and suspends low-priority applications. Users can later resume applications by swiping up from the bottom of the screen or through notification shade, allowing the system to handle power management tasks automatically while preserving user access when needed.
