Solution Overview
Problem
Portable electronic devices face challenges in managing power consumption effectively, as fixed global time settings for backlighting do not adapt to the specific needs of active applications, leading to inefficient power usage and potential reduction in battery life.
Innovation Solution
A resource management module dynamically sets full-power and reduced-power mode timers based on application-specific requirements, adjusting power modes in response to application initiation, switching, and user inputs to optimize power usage without compromising user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fixed global time settings are used for backlighting, then device complexity is reduced and ease of operation is improved, but power consumption efficiency deteriorates and battery life is reduced
Solution Approach 1:
The patent implements dynamic power mode timers that automatically adjust backlighting duration based on the characteristics of active applications. Instead of fixed global settings, the system dynamically selects between short-duration and long-duration power modes depending on whether the active application is likely to generate user input, thereby optimizing power consumption while maintaining user experience.
Solution Approach 2:
The system incorporates feedback mechanisms by monitoring which applications are active and using this information to adjust power mode settings. The resource management module continuously evaluates application characteristics and modifies backlighting timer settings accordingly, creating a closed-loop system that adapts to actual device usage patterns.
2Device complexity
If fixed global time settings are used for backlighting, then device complexity is reduced, but power consumption efficiency deteriorates
Solution Approach 1:
The patent segments the power management system into distinct application profiles, each with predetermined power mode characteristics. By categorizing applications into groups with similar input patterns, the system can apply appropriate power settings without requiring complex real-time analysis of every application's behavior, thus balancing simplicity with efficiency.
Solution Approach 2:
The system changes key parameters (backlighting timer duration) based on application type. By pre-defining power mode parameters for different application categories, the system achieves efficient power management through parameter selection rather than complex calculation, maintaining relative simplicity while improving energy efficiency.
3Use of energy by moving object
If power modes are reduced to save energy, then power consumption efficiency is improved, but user experience deteriorates
Solution Approach 1:
The system dynamically adjusts power mode settings based on the active application's characteristics. By selecting appropriate timer durations from predefined profiles, the system ensures that backlighting remains on long enough for applications requiring user interaction while reducing power consumption for applications unlikely to generate input, thus maintaining user experience while improving energy efficiency.
4Use of energy by moving object
If application-specific power requirements are implemented, then power consumption efficiency is improved, but device complexity increases
Solution Approach 1:
The patent divides applications into segmented categories with predetermined power mode profiles. This segmentation approach allows the system to implement application-specific power management by simply identifying which category the active application belongs to, rather than requiring complex individual analysis of each application's power needs.
Solution Approach 2:
The system implements application-specific power management by changing power mode parameters based on application category. Pre-defined power profiles for different application types enable the system to adjust settings efficiently without requiring complex real-time computation, thus improving power efficiency while limiting the increase in device complexity.

AI summary
An electronic device includes a compute system configured to concurrently execute a primary application and one or more secondary applications, one or more subsystems configured to operate in a full-power mode and one or more reduced-power modes, and a resource management module including one or more power mode timers. The resource management module sets a full-power mode timer based on an application-specific full-power requirement for the primary application executing on the electronic device, and instructs the one or more subsystems to operate in full-power mode for a duration of the full-power mode timer. Responsive to an indication of an input to the electronic device, the indication including an input-specific full-power requirement, the resource management module increases the duration of the full-power mode timer based on the duration of the application-specific full-power requirement for the primary application.
