Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining battery wear in mobile electronic devices, particularly Android devices with non-removable batteries, are inconvenient, time-consuming, and require dedicated hardware, which is not always feasible or accurate.
Innovation Solution
A software-based method that calculates battery wear by accessing historical battery status data from a mobile device's memory, averaging estimates of actual capacity across different charge ranges to improve accuracy and account for variations in charge behavior, without the need for active monitoring or physical battery testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If physical battery testing is used to determine battery wear, then measurement precision is improved, but loss of time and ease of operation deteriorate
Solution Approach 1:
The patent replaces the mechanical/physical battery testing system with a software-based calculation system. Instead of physically discharging and charging the battery to measure wear, the system uses software to calculate wear based on historical battery status data, charge cycles, and capacity information stored in the device memory, thereby eliminating the time-consuming physical testing process while maintaining measurement accuracy
Solution Approach 2:
The patent performs preliminary data collection by continuously monitoring and storing battery status information, charge cycles, and capacity data during normal device operation. This preliminary action accumulates the necessary data in advance, so that when battery wear needs to be determined, the calculation can be performed immediately using pre-collected data without requiring time-consuming physical tests
2Measurement precision
If physical battery testing is used to determine battery wear, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent replaces the mechanical/physical battery testing system with a software-based calculation system. Instead of physically discharging and charging the battery to measure wear, the system uses software to calculate wear based on historical battery status data, charge cycles, and capacity information stored in the device memory, thereby eliminating the time-consuming physical testing process while maintaining measurement accuracy
Solution Approach 2:
The patent enables the mobile device to perform battery wear determination autonomously using its own internal resources - processing power, memory, and sensors. The device calculates its own battery wear by utilizing data already stored in its memory, eliminating the need for external battery testing equipment and making the process as convenient as any other device operation
3Measurement precision
If dedicated hardware is used to determine battery wear, then measurement precision is improved, but device complexity increases
Solution Approach 1:
