Battery Charging Icon Display Using Voltage-Based Stage Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable terminals do not effectively display the charging state or remaining capacity of their batteries, forcing users to wait without knowing how much longer the battery needs to recharge.
Innovation Solution
A method and apparatus that measure the charged voltage of a battery and sequentially display icons corresponding to charging stages, allowing users to check the charging state, capacity, and remaining capacity by determining the charging stage based on stored icon data and displaying these icons on a display unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional battery charging display methods are used, then the device structure remains simple, but the user cannot check charging state or remaining capacity information
Solution Approach 1:
The battery charging process is segmented into multiple stages (first charging stage, second charging stage, third charging stage) based on voltage thresholds. Each stage is represented by distinct icons showing different filling levels (e.g., 1/4 filled, 2/4 filled, 3/4 filled, fully filled). This segmentation allows the system to provide detailed charging state information without requiring complex hardware, as the complexity is managed through software-based voltage threshold detection and icon selection.
2Loss of information
If detailed charging state information is displayed, then user awareness of charging progress improves, but the display system becomes more complex
Solution Approach 1:
The display system dynamically selects and updates icons based on real-time battery voltage measurements. As the battery charges and voltage increases, the system automatically transitions between different icon representations (from empty to partially filled to fully filled). This dynamic update mechanism provides continuous charging progress information without requiring manual user intervention or complex interface changes, resolving the contradiction between information completeness and system complexity.
3Loss of time
If conventional charging display is used, then the display system remains simple, but the user cannot determine remaining charging time
Solution Approach 1:
The system implements a feedback mechanism where the displayed icons provide real-time information about charging progress and estimated remaining time. By measuring battery voltage and comparing it against predefined thresholds for different charging stages, the system feedbacks charging state information to the user through intuitive visual icons. This allows users to understand how much charging remains and estimate waiting time without requiring complex timing calculations or additional sensors.
