Charging System with Mobile Terminal Control Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charging systems for mobile terminals with base batteries suffer from low charging efficiency and a high risk of over-discharge, particularly when the base battery is used to charge both the mobile terminal and itself simultaneously.
Innovation Solution
A charging system with a mobile terminal control module that manages charging by disconnecting the base battery from the charger once the mobile terminal is fully charged, and a dual-channel selection switch that dynamically selects between USB and AC charging based on voltage thresholds to prevent over-discharge and optimize charging efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If the base battery charges both the mobile terminal and itself simultaneously, then the charging process can continue without interruption, but the charging efficiency becomes very low and the charging time becomes too long
Solution Approach 1:
The charging process is segmented into distinct phases: first charging the mobile terminal, then charging the base battery. The dual-channel selection switch separates the charging paths, allowing the system to sequentially serve different charging needs rather than attempting simultaneous charging of both devices, thereby improving overall charging efficiency.
Solution Approach 2:
The system performs preliminary action by prioritizing the mobile terminal charging first. The control module detects when the mobile terminal is fully charged before initiating base battery charging, ensuring that the more urgent charging need is satisfied first, then the base battery is charged in the subsequent phase.
2Adaptability or versatility
If the base uses base battery to charge mobile terminal, then charging can occur without base charger, but the base battery is prone to over-discharge phenomenon
Solution Approach 1:
The control module implements feedback by continuously monitoring the base battery voltage through the dual-channel selection switch. When the voltage drops below the threshold, the system automatically switches charging sources or stops discharge, preventing over-discharge while maintaining the flexibility to charge the mobile terminal using the base battery when needed.
Solution Approach 2:
The dual-channel selection switch acts as an intermediary between the base battery and the mobile terminal. It intelligently manages the power flow, selecting appropriate charging sources (base charger or base battery) and protecting the base battery from over-discharge by preventing direct connection when voltage is insufficient.
3Loss of time
If the base charger charges both mobile terminal and base battery at the same time, then charging time is reduced, but the charging efficiency becomes very low
Solution Approach 1:
The system dynamically adjusts the charging configuration based on real-time conditions. The dual-channel selection switch enables the base charger to charge the mobile terminal with high efficiency when needed, while sequentially charging the base battery afterward, optimizing the balance between charging time and charging efficiency rather than using a fixed simultaneous charging mode.
