Adaptable Power-Budget System for Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices face challenges in managing battery usage effectively, leading to premature shutdowns due to power drainage from internet and graphic-rich applications, which limits their functionality and critical operations.
Innovation Solution
Implementing an adaptable power-budget system that classifies processes using a ring hierarchy, selectively providing power from a primary and secondary battery based on process priority, with the secondary battery used only when necessary, and updating the classification template based on usage patterns and user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If users limit power usage by limiting 3G or 4G communications, disabling background synchronization processes, and reducing screen brightness, then battery life is extended, but the full use and functionality of the mobile device is limited
Solution Approach 1:
The patent segments the battery into two separate batteries: a first battery for powering critical processes and a second battery for powering non-critical processes. This segmentation allows the device to maintain full functionality by enabling both critical and non-critical processes to run simultaneously on different power sources, while extending overall battery life by managing power consumption across multiple independent sources.
2Adaptability or versatility
If internet or graphic rich applications are used, then device functionality and user experience are enhanced, but battery is drained more quickly causing device shutdown
Solution Approach 1:
The patent applies local quality by assigning different power sources to different types of processes based on their criticality. Critical processes (telephony, messaging, basic communications) are powered by the first battery with longer duration, while non-critical processes (internet applications, graphic-rich applications, background synchronization) are powered by the second battery. This allows intensive applications to function fully without compromising the battery life needed for critical operations.
3Device complexity
If a single battery powers all processes, then device complexity is minimized, but power management flexibility is reduced leading to premature shutdowns
Solution Approach 1:
The patent implements dynamic power management through a power management component that continuously monitors process criticality and battery status, dynamically assigning processes to appropriate batteries. The system can adaptively switch between batteries based on real-time conditions, process requirements, and battery charge levels, providing flexible and reliable power management that responds to changing operational demands.
