Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices, such as wearable devices for extended reality experiences, face power management challenges due to limited battery capacity and space, leading to reduced runtimes and interruptions during user activities, as they often require manual charging via outlets or docks, disrupting the user experience.
Innovation Solution
A system for managing power distribution among electronic devices based on predefined policies, which monitors state data including power conditions, location, activity levels, and user preferences to wirelessly transfer power from one device to another, optimizing power usage and extending runtime without interrupting user activities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If battery capacity is increased to extend runtime, then device runtime is improved, but device volume and weight increase
Solution Approach 1:
The patent combines multiple electronic devices into a wireless power distribution system where devices share power resources. The head-mounted device can wirelessly receive power from accompanying devices, effectively merging power capacities across devices to extend runtime without increasing individual device volume.
Solution Approach 2:
Accompanying devices serve multiple functions: they act as both computing devices for extended reality processing and as wireless power sources. This multi-functionality allows the system to extend runtime without adding dedicated power storage components to the head-mounted device.
2Duration of action of moving object
If manual charging is implemented via power outlet or charging dock, then device power is replenished, but user activity is interrupted
Solution Approach 1:
The system implements automatic wireless power transfer where the head-mounted device autonomously receives power from accompanying devices based on real-time power condition monitoring. The power management component automatically determines when and from which device to charge, eliminating the need for manual user intervention and maintaining activity continuity.
Solution Approach 2:
The wireless power distribution system enables continuous power replenishment during user activities without interruption. The system continuously monitors power conditions and maintains power transfer operations in the background, ensuring uninterrupted extended reality experiences while keeping devices charged.
3Ease of operation
If wireless power transfer is implemented between devices, then charging convenience is improved, but system complexity increases
Solution Approach 1:
The patent divides the power management functionality into separate components: power condition monitoring is handled by individual devices, while the head-mounted device's power management component makes centralized charging decisions. This segmentation distributes system complexity across multiple simple components rather than concentrating it in one complex unit.

Data Source
AI summary
A system for managing power distribution among devices based on one or more applicable power policies. The system can receive state data, including power condition data representing power conditions associated with a plurality of devices including a first device. The system can determine, based on the power condition data, a second device to wirelessly provide power to the first device. The system can generate a power distribution command configured to cause wireless power transmission from the second device to the first device and send the power distribution command to at least one of the first device or the second device to initiate wireless power transmission from the second device to the first device.
