Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional charging devices face power overload issues when multiple mobile electronic devices are charged simultaneously, leading to delayed charging completion due to the limited power distribution system, especially in environments like schools where multiple devices are used for digital teaching.
Innovation Solution
A smart charging device with multiple modules such as power detection, abnormal detection, periodic alternating charging, and over-charging protection modules that allocate charging time and manage power distribution across multiple regions, allowing for efficient charging even when the total power required exceeds the device's maximal supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If multiple mobile electronic devices are charged simultaneously, then the charging power requirement increases, but the power distribution system becomes overloaded
Solution Approach 1:
The patent implements periodic alternating charging by dividing charging regions into groups and alternately supplying power to different groups in time-division manner. This allows the charging device to serve multiple devices simultaneously across different time periods, effectively increasing the average charging power capacity without exceeding the instantaneous power supply limit, thereby resolving the contradiction between charging power demand and power distribution system capacity.
2Reliability
If charging regions are supplied with power by turns region by region, then power overload is prevented, but charging completion period is delayed
Solution Approach 1:
The patent segments the charging regions into multiple groups and implements parallel charging within each group during their respective time slots. By organizing charging regions into structured groups and enabling simultaneous charging operations across different groups in a time-division multiplexing scheme, the system prevents power overload while significantly reducing total charging completion time compared to sequential region-by-region charging.
Solution Approach 2:
The system employs periodic alternating charging cycles where different groups of charging regions are activated in sequence. This periodic operation allows multiple devices to be charged in parallel across different time periods, preventing instantaneous power overload while minimizing overall charging time through efficient time utilization.
3Power
If the total power required by mobile electronic devices exceeds the maximal power supply, then charging demand is met, but power overload occurs
Solution Approach 1:
The patent incorporates a power detection module that continuously monitors the real-time power consumption of connected devices and compares it against the maximal power supply capacity. This feedback mechanism enables the control unit to dynamically adjust charging allocation, activate or deactivate specific charging regions, and implement periodic alternating charging schemes that ensure total power demand can be satisfied over time without causing instantaneous power overload, thus resolving the contradiction between meeting charging demand and preventing harmful power overload.
