Charger Detecting Abnormal Charge States to Prevent Device Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current charging systems fail to detect and respond to abnormal charge states in electronic devices, leading to potential damage due to increased output current, as they do not effectively monitor or adjust power supply during charging.
Innovation Solution
An information processing method and electronic device system that allows a charger to receive and analyze information from an electronic device, determining its charge state and adjusting power supply accordingly, reducing output power consumption when an abnormal state is detected.

Engineering Contradiction Analysis
1Productivity
If the output current of the charge adapter is increased to match the increased battery capacity, then the charging speed is improved, but the risk of device damage due to undetected failures increases
Solution Approach 1:
The charge adapter actively queries the electronic device about its charge state and receives feedback information. Based on this feedback, the adapter can detect abnormal conditions and adjust or stop power output to prevent device damage, thus resolving the contradiction between high charging speed and device safety
Solution Approach 2:
The electronic device itself monitors its own charge state and provides this information to the charge adapter. This self-service mechanism enables the adapter to make informed decisions about power delivery, allowing high current charging while maintaining safety through the device's own monitoring capabilities
2Reliability
If the charge adapter continuously monitors the charge state to detect abnormalities, then the device safety is improved, but the system complexity increases
Solution Approach 1:
The electronic device performs self-monitoring of its charge state and reports to the adapter. This shifts the monitoring burden from the adapter to the device itself, reducing the complexity of the adapter while maintaining safety through the device's own monitoring capabilities
Solution Approach 2:
The communication interface between the adapter and device serves multiple functions: it transmits charge state information for safety monitoring, and can also handle other device management tasks. This multi-functionality reduces the need for separate dedicated monitoring hardware, thereby reducing overall system complexity
