Mobile Device Battery Conservation via Link Termination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile wireless devices experience shortened battery life due to periodic high power radio signal transmission while maintaining connections to wireless networks, even when not in use, leading to significant energy drain.
Innovation Solution
Implementing a system that selectively terminates and re-establishes the communication link with a wireless network based on specified intervals, user actions, or network usage patterns to minimize unnecessary power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the device maintains a continuous communication link with the wireless network, then network availability and responsiveness are improved, but battery life deteriorates due to periodic high power radio signal transmission
Solution Approach 1:
The system implements periodic monitoring of network usage patterns and application states, transitioning the communication link between active and terminated states at regular intervals based on detected usage conditions. This periodic evaluation allows the device to maintain network connectivity only when necessary, reducing energy consumption while preserving network availability during actual usage periods.
Solution Approach 2:
The communication link state is dynamically adjusted based on real-time detection of application network requirements and user interaction patterns. The system transitions from a static continuous connection model to a dynamic state where the link is actively maintained only when applications indicate network needs, otherwise terminated to conserve battery power.
2Use of energy by moving object
If the communication link is terminated to conserve battery power, then energy consumption is reduced, but network responsiveness and user experience deteriorate
Solution Approach 1:
The system performs preliminary detection of application network requirements before actually needing network communication. By monitoring application states and user interactions in advance, the system re-establishes the communication link proactively before network operations are required, ensuring seamless user experience without noticeable delays.
Solution Approach 2:
The system continuously monitors application network usage patterns and user interaction feedback to dynamically adjust link termination and re-establishment timing. This feedback mechanism ensures that link state changes are optimized based on actual usage patterns, preventing both unnecessary power consumption and degradation of user experience.
3Reliability
If the device re-establishes the communication link frequently, then network availability is maintained, but energy consumption increases due to repeated link establishment
Solution Approach 1:
The system employs intelligent detection mechanisms that allow applications to self-report their network requirements. By leveraging application-level information about network needs, the system avoids frequent link re-establishment by maintaining connectivity only when applications actually require network access, thereby reducing energy drain from repeated link establishment while preserving network availability when needed.

AI summary
The battery life of a mobile device operating in a wireless network environment is extended by terminating network communication activities after a specified period of time. Network communication activities may be restored when any one of a specified number of user actions are detected.
