Solution Overview
Problem
Wireless charging of electronic devices often obscures the display of one device when placed under another, making it difficult for users to verify charging status without flipping them, which is inconvenient and inefficient.
Innovation Solution
An electronic device equipped with a charging circuit, sensor circuit, and processor that aligns charging coils for efficient power transfer while displaying charging information on the visible display, including battery level, power consumption, and estimated charging time, using separate frequencies for power and information transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the electronic device is placed under the external electronic device for wireless charging, then power transmission efficiency is improved, but the display of the electronic device becomes obscured and invisible to the user
Solution Approach 1:
The patent uses the external electronic device's display as an intermediary to show charging information that would otherwise be invisible. The processor detects the spatial relationship and controls the external device's display to present charging status, battery level, and other information, allowing users to monitor charging without seeing the obscured display directly.
Solution Approach 2:
The system implements feedback by having the external electronic device's display show charging information generated by the electronic device's processor. This creates a feedback loop where charging status is continuously communicated to the user through the visible display, resolving the information loss caused by the obscured display.
2Productivity
If the rear surfaces of the electronic device and external electronic device face each other for charging coil alignment, then wireless charging efficiency is improved, but the user cannot verify charging status
Solution Approach 1:
The external electronic device's display serves as an intermediary interface for charging verification. The processor controls this display to show charging status information, allowing users to verify charging efficiency without needing to physically rearrange or flip the devices.
Solution Approach 2:
The patent replaces the mechanical action of flipping or rearranging devices to verify charging with an electronic information display system. The processor and display system provide visual feedback about charging status, eliminating the need for mechanical manipulation of the devices.
3Power
If the electronic device transmits power to the external electronic device, then the electronic device's battery level decreases, but the user needs to monitor both devices' charging status
Solution Approach 1:
The patent merges the monitoring function into a single display interface on the external electronic device. The processor consolidates information about both devices' charging status, battery levels, and power transmission state into one unified display, eliminating the need for users to check multiple devices separately.
Solution Approach 2:
The external electronic device's display is used for multiple purposes: showing its own charging status, displaying the electronic device's battery level, and providing overall charging monitoring. This multi-functional use of a single display reduces operational complexity.
