Smartphone-Based Log Analysis for Wearable Battery Diagnostics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Battery-operated timepieces, such as wristwatches, fail to notify users of the cause of battery voltage reduction, only indicating the reduction itself, without providing insights into usage patterns that may lead to voltage depletion.
Innovation Solution
An information notification method and device that acquires log data from a time display device via wireless communication, determines the usage status based on this data, and provides information to the user regarding the status, including battery, solar cell, and hand position correction, using a smartphone and server system for data analysis and notification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If log data acquisition and usage status determination are added to notify users of battery voltage reduction causes, then information completeness is improved, but device complexity increases
Solution Approach 1:
The patent introduces a smartphone as an intermediary device that performs log data acquisition, usage status determination, and notification functions. This external mediator handles the complex data processing tasks, allowing the timepiece itself to remain relatively simple while still providing comprehensive usage status information to the user through the smartphone's display and communication capabilities.
2Loss of information
If comprehensive usage status information is provided to users, then user awareness is improved, but data processing requirements increase
Solution Approach 1:
The smartphone serves as an intermediary that performs the automated determination of usage status based on acquired log data. It analyzes battery voltage trends, solar cell performance, hand position correction frequency, and other parameters automatically, then presents this processed information to the user in an understandable format, reducing the computational burden on the timepiece itself.
Solution Approach 2:
The system implements feedback by continuously monitoring log data from the timepiece, determining usage status, and notifying the user of findings. This closed-loop feedback mechanism enables automated analysis of battery voltage reduction causes and provides actionable information to users about their device's usage patterns and potential issues.

AI summary
A smartphone includes a receiver, a log acquirer, a determiner, an information notifier, and a display. The receiver is in wireless communication with a time display device. The log acquirer acquires log data from the time display device by the receiver. The determiner determines the usage status of the time display device on the basis of the log data acquired by the log acquirer. The information notifier provides, via the display, notification of information corresponding to the usage status determined by the determiner.
