Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The precision and reliability of battery remaining amount information obtained from power supply devices via USB Type-C connectors vary due to differences in communication standard revisions, making it difficult for users to accurately assess the operable time of power receiving devices.
Innovation Solution
An electronic apparatus with a connection unit to connect with a power supply device and a control unit that obtains first remaining amount information, calculates second remaining amount information based on operable power, and displays it with switched precision based on the reliability of the first information.

Engineering Contradiction Analysis
1Measurement precision
If the power receiving device displays operable time information calculated from battery remaining amount information obtained via USB Type-C connectors, then the user can see the operable time, but the precision and reliability of the displayed information vary depending on communication standard revisions
Solution Approach 1:
The patent applies visual differentiation through display precision changes (analogous to color changes) to indicate the reliability level of battery remaining amount information. When the information is obtained through USB Type-C connectors with varying communication standard revisions, the system adjusts the display precision to reflect the reliability level, allowing users to visually distinguish between high and low reliability information without requiring explicit labels or additional visual indicators.
2Ease of operation
If the display precision of operable time information is kept uniform regardless of information reliability, then the user interface is simple, but the user cannot recognize the difference in precision and reliability
Solution Approach 1:
The system provides feedback to the user about the reliability of battery remaining amount information by adjusting display precision dynamically. When information is obtained through USB Type-C connectors with different communication standard revisions, the display precision automatically adjusts to reflect the reliability level, giving users immediate feedback about the quality of information without requiring additional interfaces or complex displays.

AI summary
An electronic apparatus operates using power received from a power supply device, and comprises a connection unit configured to connect with the power supply device, and a control unit configured to obtain first remaining amount information related to power that can be supplied from the power supply device, calculate second remaining amount information related to power by which the electronic apparatus is operable based on the first remaining amount information, and display the second remaining amount information. The control unit switches a display precision of the second remaining amount information based on a reliability of the first remaining amount information obtained from the power supply device.
