Power Management System Grayscale Icon Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of portable devices face frustration due to limited battery duration, leading to loss of productivity and hindered technology adoption, as current power management systems fail to effectively inform users about power-consuming applications and conserve battery life.
Innovation Solution
A power management system that provides visual cues by modifying icons of high-power consumption applications to grayscale when battery power falls below a threshold, allowing users to prioritize remaining power usage by distinguishing between power-intensive and less intensive applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the device provides full functionality and access to all applications, then user productivity and experience are maintained, but battery power is depleted rapidly
Solution Approach 1:
The system continuously monitors battery power levels and provides real-time feedback to the user through visual indicators on application icons. When power falls below a threshold, high-power application icons are displayed in grayscale while low-power application icons remain in color, enabling users to make informed decisions about which applications to use to conserve battery life while maintaining productivity.
2Duration of action of moving object
If the device disables high-power applications to conserve battery, then battery duration is extended, but user access to necessary features is restricted
Solution Approach 1:
Instead of globally disabling applications or uniformly restricting all features, the system applies selective visual indicators only to high-power consuming applications. Each application icon is individually assessed and displayed in grayscale if it consumes excessive power, while low-power applications remain accessible in color. This localized approach preserves user access to necessary features while guiding power conservation decisions.
3Loss of information
If the device provides detailed power consumption information to users, then users can make informed power conservation decisions, but the system complexity increases
Solution Approach 1:
The system uses color as a visual indicator to communicate power consumption information. High-power application icons are displayed in grayscale while low-power application icons remain in color. This intuitive color-based coding system conveys complex power consumption data in a simple, easily understandable visual format that requires minimal system complexity to implement and interpret.

AI summary
An electronic device includes at least one memory unit, a plurality of applications residing on at least one of the memory units, a display screen and a portable power supply. The electronic device also includes a power management module, which has a power monitor for monitoring an amount of remaining power available from the portable power supply. A processor is operatively associated with the memory units, display screen and portable power supply. The processor is configured to indicate to a user that one or more predetermined ones of the applications should not be used in order to conserve power when the remaining power falls below the first threshold level.
