Mobile Device Power Management via Communication Capability Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication devices often run out of power before they can be recharged, particularly for users who rely heavily on them, due to limitations in battery technology.
Innovation Solution
Multiple mobile communication devices and their communication provider interactively cooperate to manage power usage by having one device assume the communication capabilities of others, placing most devices in a reduced-power mode to conserve power, ensuring communication capabilities are retained for a longer period.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mobile device operates continuously at full power, then communication capability is maintained, but battery power is depleted quickly
Solution Approach 1:
The system segments the communication function across multiple mobile devices. Instead of one device operating continuously at full power, the communication capability is divided and shared among several devices. When one device enters reduced-power mode, another device assumes its communication responsibilities, ensuring continuous coverage while reducing overall energy consumption.
Solution Approach 2:
The system dynamically adjusts the power state of individual mobile devices based on real-time conditions. Devices can transition between full-power mode (when needed for communication) and reduced-power mode (when another device is handling communication). This dynamic switching optimizes energy usage while maintaining communication reliability.
2Use of energy by moving object
If multiple mobile devices share communication responsibilities, then overall power consumption is reduced, but system complexity increases
Solution Approach 1:
Mobile devices autonomously determine their own power state based on communication needs. Each device monitors whether communication is required and independently transitions between full-power and reduced-power modes without requiring complex centralized control, thereby reducing overall system complexity while achieving power savings.
Solution Approach 2:
The system uses feedback mechanisms where devices report their power state and communication needs to the network. The communication provider uses this feedback to coordinate power management across devices, allowing for simplified individual device logic while maintaining system-wide optimization.
3Use of energy by moving object
If a device enters reduced-power mode to conserve battery, then energy is preserved, but communication capability is lost
Solution Approach 1:
The system merges the communication capabilities of multiple mobile devices into a coordinated network. When one device enters reduced-power mode and loses communication capability, another device that remains in full-power mode assumes its communication responsibilities. This merging ensures that the collective communication capability of the group is maintained even as individual devices conserve power.

AI summary
Mobile communication devices, like smartphones, cooperatively interact with one another and with a communication provider, like a cellular telephone provider, to manage power usage by the mobile devices, where the communication capabilities of the devices are still retained. For example, for two mobile devices, the first device may be placed into a reduced-power mode, while the second device remains in a non-reduced-power mode. The second device at least partially assumes the communication capability of the first device so that the communication capability of the first device is retained.
