Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to design a charging system for terminal devices that efficiently manages the charging of batteries with different capacities, preventing overcharging of smaller capacity batteries while minimizing the installation space and complexity, as larger capacity batteries increase the volume and installation difficulty.
Innovation Solution
A charging system comprising a first battery with a larger capacity, a second battery with a smaller capacity, a charging component, and a control component that uses voltameters and processors to detect the electric quantity of both batteries and control a switch device to disconnect or connect the second battery from the charging component based on preset thresholds, ensuring safe and efficient charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a large-capacity battery is used to improve terminal device endurance, then the battery capacity increases, but the battery volume increases and installation difficulty increases
Solution Approach 1:
The patent divides the battery system into multiple battery packs with different capacities (first battery pack with larger capacity, second battery pack with smaller capacity). This segmentation allows the system to achieve high total capacity while keeping individual pack volumes manageable for easier installation and better space utilization within the terminal device.
2Quantity of substance
If a large-capacity battery is used to improve terminal device endurance, then the battery capacity increases, but the installation difficulty increases
Solution Approach 1:
By segmenting the battery into multiple packs, the system reduces individual pack size and weight, making them easier to handle, install, and replace. The modular design simplifies the installation process and reduces the technical difficulty compared to installing a single large-capacity battery.
Solution Approach 2:
The patent implements dynamic control of the battery system through a control circuit that monitors electric quantities and automatically switches between different battery packs based on charging status and capacity requirements. This dynamic management optimizes the balance between capacity utilization and installation complexity.
3Quantity of substance
If multiple batteries with different capacities are used, then the total capacity requirement is met, but the charging management complexity increases
Solution Approach 1:
The control circuit continuously monitors the electric quantity of each battery pack through feedback mechanisms and automatically adjusts the charging configuration. When the second battery pack reaches full charge, the system automatically switches to charge only the first battery pack, eliminating the need for manual intervention and reducing operational complexity despite the multi-battery configuration.
Solution Approach 2:
The control circuit acts as an intermediary that manages the complexity of charging multiple batteries with different capacities. It handles the switching logic, monitoring, and coordination between batteries, isolating the user from the complexity while enabling efficient multi-battery management.

AI summary
A charging system includes: a first battery, a second battery, a charging component, and a control component. A capacity of the second battery is smaller than that of the first battery. The second battery includes a cell and a switch device connected to the cell. The charging component is connected to the first battery and connected to the second battery via the switch device, and configured to output a charging current to the first battery and the second battery. The control component is connected with the first battery and the second battery, and configured to detect electric quantity of the first battery and the second battery during a charging process and control the switch device to turn on or turn off based on the electric quantity.
