Battery Status Display Logic for Multi-Battery Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to effectively display battery remaining power in electronic devices without degrading the visibility of the display unit, especially when multiple batteries are used, as existing solutions often overwhelm the display with information, impacting user experience.
Innovation Solution
An electronic device with a control unit and display unit that selectively displays the remaining power of a first battery and a second battery based on their respective conditions, only showing the second battery's power when it falls below a threshold, thereby prioritizing the visibility of the first battery's status.

Engineering Contradiction Analysis
1Loss of information
If the remaining powers of multiple batteries are displayed on the display unit at all times, then the user is notified of battery conditions, but the viewability of the display unit is degraded
Solution Approach 1:
The display unit dynamically adjusts the information displayed based on battery conditions. When a battery's remaining power falls below a threshold, the display switches from showing only the first battery's power to showing both the first and second battery powers, adapting the display content to the current operational context
Solution Approach 2:
The system changes the display parameters (which battery information is shown) based on the remaining power threshold parameter. When the second battery's power drops below the threshold, the display parameter changes to include both battery powers, otherwise only the first battery power is displayed
2Loss of information
If the remaining power of the second battery is always displayed, then complete battery information is provided, but the display unit becomes cluttered with redundant data
Solution Approach 1:
The system extracts and displays only the relevant battery information based on current conditions. When the second battery's remaining power is above the threshold, its display is extracted/omitted to reduce clutter. When it falls below the threshold, the second battery information is extracted and added to the display
Solution Approach 2:
The system applies partial action by displaying only necessary battery information rather than all battery information continuously. It shows exactly what is needed (first battery power always, second battery power only when below threshold) without excessive display of redundant data

AI summary
An electronic device, which can charge a battery selected from a plurality of batteries and can drive the battery as a power feeding source, includes a control unit and a display unit. When a remaining power of a second battery that does not correspond to a first battery selected as a battery to be charged or the power feeding source among the plurality of batteries is higher than or equal to a predetermined threshold value, the control unit causes the display unit to display a remaining power of the first battery from among the remaining power of the first battery and the remaining power of the second battery, and when the remaining power of the second battery is lower than the threshold value, the control unit causes the display unit to display the remaining power of the first battery and the remaining power of the second battery.
