Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current switching power modules in electronic devices, such as tablet computers, often struggle to meet the power demands of high-power loads, leading to repeated battery charging and reduced battery life when the device is nearly fully charged.
Innovation Solution
A power supply method and device that utilize two charging assemblies to supply power to loads and a battery, dynamically adjusting the power supply based on current conditions to balance load distribution and prevent battery discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a single switching power module is used to supply power to loads, then the device structure is simple, but the power supply capacity is insufficient for high-power loads
Solution Approach 1:
The power supply system is divided into a first charging assembly and a second charging assembly, each capable of independently supplying power to loads and/or charging the battery. This segmentation allows the system to handle high-power loads more effectively by distributing the power supply task across multiple modules, thereby increasing overall power supply capacity without requiring a single complex high-power module.
2Power
If the battery is used to supplement power for high-power loads when the device is nearly fully charged, then the power supply capacity is sufficient, but the battery undergoes repeated charging and discharging which reduces battery life
Solution Approach 1:
The control module continuously monitors the charging state of the battery and the power consumption of loads, dynamically adjusting the power supply configuration. When the battery is nearly fully charged, the system detects this state and switches to a configuration where the second charging assembly directly powers high-power loads, preventing the battery from undergoing repeated charging cycles and thereby extending battery life.
Solution Approach 2:
The system dynamically switches between different power supply configurations based on real-time conditions. It can transition from battery supplementation mode to direct power supply mode from the second charging assembly when the battery is fully charged, and vice versa. This dynamic adaptation ensures sufficient power supply capacity while protecting battery health by avoiding unnecessary charge-discharge cycles.
3Power
If the first charging assembly supplies power to both the first load assembly and the battery, then the power distribution is efficient, but the power supply capacity for multiple high-power loads is insufficient
Solution Approach 1:
The power distribution system is segmented into two independent charging assemblies, each capable of handling power supply tasks. The first charging assembly manages the first load assembly and battery charging, while the second charging assembly is dedicated to supplying power to high-power loads. This segmentation increases the total power supply capacity and allows independent optimization of each charging path.
Solution Approach 2:
Each charging assembly is designed with multi-functionality: the first charging assembly can both power the first load assembly and charge the battery, while the second charging assembly can power the second load assembly and also charge the battery. This universal design provides flexibility in power distribution and enables the system to handle various power supply scenarios with increased capacity.

AI summary
A power supply method includes determining that an electronic device is connected to an external power supply, configuring a first supply power of a first charging assembly, of the electronic device, that is configured to supply power to a first load assembly and a battery, and a second supply power of a second charging assembly, of the electronic device, that is configured to supply power to a second load assembly and the battery, in response to power being supplied to the first load assembly and the second load assembly, obtaining a first supply current of the first charging assembly to the battery and a second supply current of the second charging assembly to the battery, and in response to determining that the first supply current and the second supply current meet a condition, adjusting the first supply power and the second supply power.
