Context-Aware Device Power Control for Battery Preservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power management systems in marine vessels and similar applications often inappropriately shut down devices based on battery state or voltage thresholds, leading to inconvenience and potential device malfunction, as they do not consider the operational context of the devices.
Innovation Solution
A control system that determines which devices are consuming power, identifies candidate devices for power reduction, and uses a power control model to pair devices that consume power in related patterns, only reducing power when complementary devices are in a non-power consuming state, ensuring that devices are only shut down when not in use or not needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If existing power management systems shut down devices based on battery state or voltage thresholds, then power consumption is reduced, but device operational context is not considered leading to inappropriate shutdowns
Solution Approach 1:
The system continuously monitors the operational state of multiple devices and uses this feedback to dynamically adjust power management decisions. The control system determines which devices are currently consuming power and uses this real-time information to make intelligent decisions about which candidate devices can be safely shut down without affecting the operational reliability of the system.
Solution Approach 2:
The power management system automatically identifies candidate devices for shutdown by analyzing the power consumption patterns and operational states of all devices. The system serves itself by making autonomous decisions about power allocation without requiring manual intervention, thereby reducing power consumption while maintaining device reliability through context-aware control.
2Loss of energy
If existing power management systems shut down devices based on voltage thresholds, then battery preservation is improved, but user convenience deteriorates due to unnecessary shutdowns
Solution Approach 1:
The system performs preliminary analysis of device power consumption patterns and operational contexts before making shutdown decisions. By determining which devices are currently consuming power and identifying candidate devices in advance, the system ensures that only appropriate devices are shut down, thereby preserving battery life without compromising user convenience or causing unnecessary disruptions.
Solution Approach 2:
The system dynamically changes the power management parameters based on the operational state of devices. Instead of using fixed voltage thresholds, the control system adjusts power allocation decisions based on real-time parameters such as device power consumption status, operational context, and battery state, thereby optimizing both battery preservation and user convenience.
3Device complexity
If simple threshold-based control is used, then system complexity is reduced, but intelligence and adaptability of power management deteriorates
Solution Approach 1:
The power management system segments the control process into distinct functional modules: determining which devices are consuming power, identifying candidate devices for shutdown, and executing control decisions. This segmentation maintains system complexity at a manageable level while enabling intelligent and adaptable power management through structured analysis of device operational contexts.
Solution Approach 2:
The system implements dynamic power management by continuously adapting control decisions based on the operational state of devices. The control system dynamically determines which devices are consuming power and adjusts candidate device selection accordingly, thereby achieving high intelligence and adaptability without requiring overly complex system architecture.

AI summary
A method for automatically reducing the power consumed by devices from a power source having a limited amount of power. The method includes determining with a control system which of the devices is consuming the power. The method further includes identifying a candidate device among the devices to tentatively control to reduce the power consumed by the candidate device. The method further includes accessing a power control model, where the power control model includes pairings of the candidate device with complementary devices among the devices, and where the devices in each of the pairings consume the power in a related pattern. The method further includes controlling the candidate device to reduce the power consumed thereby only when each of the complementary devices in each of the pairings in the power control model are determined to be in a non-power consuming state.
