Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information handling systems lack an efficient method for coordinated power management across multiple devices associated with the same user, leading to suboptimal battery usage and user experience during transitions between devices.
Innovation Solution
A power management system that detects and links multiple information handling systems via a communication network, allowing for power state messaging and adaptive power control based on context changes, such as proximity and usage patterns, to optimize power consumption across all connected devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If power control is implemented in each device independently, then each device can manage its own power consumption, but coordinated power management across multiple devices is not achieved leading to suboptimal battery usage
Solution Approach 1:
The patent merges power management functions across multiple independent devices by establishing a communication network that links them. The power management module in each device communicates with other devices to coordinate power states, effectively combining previously separate power control systems into a unified multi-device power management framework.
Solution Approach 2:
The power management module is designed with multi-functionality to handle both independent device power control and coordinated multi-device power management. It can detect context changes locally and also communicate with other devices to receive and send power states, adapting its behavior based on whether it's operating in standalone or coordinated mode.
2Device complexity
If devices operate independently without communication, then device complexity is reduced, but user experience during transitions between devices deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where devices continuously monitor their own context changes (such as proximity changes, usage states) and communicate these to other devices in the network. Other devices receive this feedback and adjust their power states accordingly, creating a closed-loop system that improves user experience during transitions without requiring major architectural changes to individual devices.
3Loss of energy
If power states are not synchronized across devices, then communication overhead is minimized, but battery usage optimization is reduced
Solution Approach 1:
The system performs preliminary actions by establishing the communication network and power management links between devices before actual power optimization is needed. Context changes are detected and communicated proactively, allowing receiving devices to prepare for upcoming power state transitions. This preliminary coordination reduces the need for frequent real-time communication during actual power management operations.

AI summary
A system, method, and computer-readable medium are disclosed for performing a power management operation for a plurality of information handling systems associated with the same user. With the power management operation, a plurality of information handling systems are detected and linked together using a communication network/path to enable power control among the plurality of information handling systems. Additionally, in certain embodiments, the power management operations allow power messages be to communicated among the plurality of information handling system. In various embodiments, a power state of each system is checked and if there is a change in system context or power state in one of the communicating systems, a message is generated and provided to other linked systems. The receiving systems can now change their respective power state based on the message received.
