Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In emerging market regions with minimally developed electrical utility infrastructures, residents face challenges in recharging multiple mobile communication devices due to limited and unreliable electricity supply, making it difficult to charge devices simultaneously.
Innovation Solution
A device and system that allow multiple mobile communication devices to be charged based on priority, where the device with the highest priority receives charge first, and devices can communicate wirelessly to determine and set their charging order, enabling partial charging of lower-priority devices to allow minimal operation before fully charging higher-priority devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple devices are connected to a single electrical outlet for charging, then the ability to charge multiple devices is improved, but the charging efficiency and priority management deteriorate
Solution Approach 1:
The patent segments the charging process by dividing devices into different priority groups (first priority, second priority, third priority). Each priority group receives charging current in a segmented manner based on their priority level, allowing the system to handle multiple devices simultaneously while maintaining charging efficiency through structured current distribution.
Solution Approach 2:
The patent implements dynamic current distribution where the charging current is dynamically adjusted based on device priority and charging status. The system dynamically determines which devices receive current at different times and at what rates, optimizing charging efficiency while accommodating multiple devices connected to a single outlet.
2Ease of operation
If devices are charged simultaneously without priority management, then charging accessibility is improved, but the reliability of critical device charging deteriorates
Solution Approach 1:
The patent applies preliminary action by determining device priorities and establishing charging sequences before actual charging begins. Devices are pre-categorized into priority groups, and the system pre-determines the charging schedule, ensuring that critical devices are guaranteed charging access while maintaining ease of operation for all connected devices.
Solution Approach 2:
The patent implements feedback mechanisms where devices communicate their charging status and priority requirements to the charging system. The system continuously monitors charging progress and adjusts current distribution based on feedback from devices, ensuring reliable charging for critical devices while maintaining accessibility for all connected devices.
3Use of energy by moving object
If limited electrical resources are shared among multiple devices, then resource utilization is improved, but the charging speed and time for individual devices deteriorate
Solution Approach 1:
The patent implements periodic action by cycling through different priority groups in a structured sequence. The charging system periodically switches between charging different priority groups, with each group receiving dedicated charging current during its designated time period. This periodic approach optimizes resource utilization while minimizing total charging time through efficient time-multiplexed current distribution.

AI summary
Disclosed are a device, system and method for multiple mobile communication devices that may be charged according to their relative priority and/or for multiple mobile communication devices that may be charged to a minimum level. The devices may be connected in any order physically, but based upon their relative charging priority the device with the highest priority may receive a charge first. The device with second highest priority may receive a charge second. Their relative priority may be communicated between the devices by wireless communication. In one embodiment, one or more devices may receive a minimum charge to allow operation, before the devices with the highest priorities are fully charged. In regions where electrical utility infrastructures are minimally developed users may share electrical facilities to recharge a plurality of mobile communication devices so that the devices with the highest priority of the grouped devices are fully charged first.
