Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile computing devices used in service applications, such as on-demand transportation services, face challenges in managing battery life efficiently, particularly when receiving continuous and intensive network communications, leading to rapid energy consumption and reduced operational time.
Innovation Solution
A service application on the mobile device dynamically adjusts display modes based on battery state, switching to low-energy modes when battery levels are low and switching back to regular modes for time-limited network events to conserve energy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the mobile device uses regular display mode continuously, then the display quality and user experience are maintained, but the battery life is reduced due to high energy consumption
Solution Approach 1:
The display mode is dynamically adjusted based on real-time detection of time-limited network events. The system transitions between low-energy display mode (for extended battery life) and regular display mode (for event notifications), making the display behavior adaptive rather than static. This resolves the contradiction by allowing the system to optimize energy consumption during normal operation while maintaining display quality when needed.
Solution Approach 2:
The patent changes the display parameter (brightness, refresh rate, or display activation) based on the operational context. By detecting time-limited network events and adjusting display parameters accordingly, the system reduces energy consumption during non-event periods while ensuring adequate display performance during event notifications, thus balancing battery life and energy consumption requirements.
2Loss of energy
If the mobile device switches to low-energy display mode, then energy consumption is reduced and battery life is extended, but the display visibility for time-sensitive information may be insufficient
Solution Approach 1:
The system continuously monitors network communications for time-limited events and uses this feedback to determine when to switch from low-energy display mode to regular display mode. This feedback mechanism ensures that energy-saving mode does not compromise information visibility, as the system activates full display performance precisely when time-sensitive information needs to be communicated to the user.
Solution Approach 2:
The display system operates in periodic cycles, alternating between low-energy mode during extended periods and regular mode during brief event notification windows. This periodic action allows the system to minimize energy consumption during non-urgent periods while ensuring adequate information visibility during time-limited events, effectively resolving the contradiction between energy savings and information delivery.
3Measurement precision
If the mobile device continuously monitors network events, then time-sensitive information is captured accurately, but energy consumption increases
Solution Approach 1:
Instead of continuous full-monitoring mode, the system uses partial monitoring by detecting time-limited network events only when necessary. The event detection mechanism activates or intensifies when time-limited events are anticipated or detected, while maintaining reduced monitoring during stable periods. This partial action approach maintains sufficient event detection accuracy while significantly reducing overall energy consumption compared to continuous full monitoring.

AI summary
A service application operates on a mobile computing device of a user to determine a battery state. Based on the determined battery state, a first display mode is implemented in which a display output is configured to reduce energy. When the first display mode is implemented, the service application can respond to a time-limited network event by automatically switching to a regular display mode for a time interval during which content of the time-limited network event is displayed. The service application can automatically switch back to the low-energy display after a duration that coincides or is based on the time interval.
