Wireless Charging Notification System for Coil Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in identifying the optimal positioning of wireless charging coils in electronic devices and charging pads, leading to inefficient or failed wireless charging due to misalignment, without proper notification from the device.
Innovation Solution
An electronic device equipped with sensors and a processor that monitors the charging state and user interaction, providing notifications through vibrations, sounds, or display messages when abnormal charging conditions occur, such as misalignment or reduced charging efficiency, to guide the user in optimizing the charging position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless charging is performed without proper notification, then charging operation continues, but user awareness of charging efficiency and alignment status deteriorates
Solution Approach 1:
The patent implements a notification system that provides feedback to the user about wireless charging status. The processor monitors charging efficiency and alignment status, then triggers notifications (visual, auditory, or haptic) to inform the user of abnormal charging conditions or misalignment, enabling the user to adjust the device position accordingly.
2Loss of information
If notification is provided when wireless charging is abnormal, then user awareness improves, but user tasks may be interrupted
Solution Approach 1:
The notification system dynamically adjusts its behavior based on device usage state. The processor determines whether the device is currently being used by the user before triggering notifications. When the device is in active use, notifications are suppressed or delayed; when the device is idle or in standby mode, notifications are provided to inform the user of charging status without interrupting ongoing tasks.
3Productivity
If user adjusts device position to optimize charging, then charging efficiency improves, but user convenience deteriorates
Solution Approach 1:
The system provides real-time feedback about charging efficiency and alignment status through notifications. This feedback guides the user in adjusting the device position on the charging pad, indicating when optimal alignment has been achieved or when adjustment is needed, thereby simplifying the optimization process.
Solution Approach 2:
The notification system automatically monitors charging parameters and determines when alignment issues exist, eliminating the need for the user to manually check or diagnose charging problems. The system self-identifies alignment issues and prompts the user for correction only when necessary.
