Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless charging systems do not provide a mechanism to change the vibration mode of a terminal to a bell sound mode or silent mode during wireless charging, which can disrupt charging efficiency and user experience.
Innovation Solution
A wireless charging method and apparatus that includes a controller to change the incoming call notification mode from a vibration mode to a bell sound mode or silent mode when an event is detected, such as an incoming call or message, and to restore the original mode after charging is complete, using either induction or resonance methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the terminal remains in vibration mode during wireless charging, then the charging operation can proceed, but the vibration may disrupt charging efficiency and battery consumption increases
Solution Approach 1:
The terminal dynamically adjusts the notification mode based on the charging state. When wireless charging is detected, the system automatically switches from vibration mode to bell sound mode, and when charging completes, it restores to the original vibration mode. This dynamic adaptation resolves the contradiction by selecting the most appropriate notification mode for each charging phase.
Solution Approach 2:
The system changes the notification parameter (vibration vs. bell sound) based on the charging condition. By detecting the wireless charging state through the wireless charger module, the controller modifies the notification mode parameter to optimize charging efficiency and reduce energy consumption during the charging process.
2Productivity
If the vibration mode is changed to bell sound mode during charging, then charging efficiency is maintained, but the user experience may be affected by unexpected mode changes
Solution Approach 1:
The system provides visual feedback through a display window that notifies users of the mode change and the reason (incoming call or message). This feedback mechanism maintains user awareness and control, preventing negative user experience while preserving charging efficiency benefits.
Solution Approach 2:
The system performs preliminary detection of incoming calls or messages before switching modes. By detecting these events first and then automatically switching to bell sound mode with user notification, the system prepares the optimal notification mode in advance, maintaining both charging efficiency and user experience.
3Adaptability or versatility
If the terminal provides automatic mode change functionality, then user convenience is enhanced, but the device complexity increases
Solution Approach 1:
The mode change control functionality is merged with the existing wireless charging control module. The wireless charger module detects charging state and communicates with the controller, which integrates the mode change logic into its existing control flow. This merging approach enhances adaptability without significantly increasing overall device complexity.
Solution Approach 2:
The controller performs multiple functions: it manages wireless charging operations, detects charging states, determines notification modes, and controls the display output. By making the controller universal and multi-functional, the system achieves enhanced adaptability through a single control unit rather than adding separate dedicated hardware for mode management.
