Wireless Charging Alignment via Visual Marking and Stopping Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless charging methods are inefficient and inconvenient due to the need for manual adjustment of electronic devices for accurate alignment, often requiring complex and costly modifications to the wireless charger or increased device prices for alignment assistance.
Innovation Solution
An electronic device displays a marking symbol to align with a corresponding symbol on a wireless charging device, using movable clamping arms and a stopping member for hands-free alignment, reducing the complexity and cost of the charging process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple sets of charging transmitting coils are added at multiple locations inside the wireless charger to solve alignment difficulty, then the charging range is enlarged, but the internal structure becomes too complicated and cost increases
Solution Approach 1:
The patent introduces a stopping member as an intermediary element that protrudes from the placement surface to physically guide and limit the position of the electronic device. This mediator component enables accurate alignment without requiring multiple complex coil structures, thus expanding the effective charging area while maintaining simple internal structure.
2Ease of operation
If a moving mechanism is provided inside the wireless charger to adjust the position of the charging transmitting coil, then alignment difficulty is solved, but the internal structure becomes too complicated and cost increases
Solution Approach 1:
Instead of making the charging coil movable to achieve alignment, the patent inverts the approach by making the electronic device position adjustable through a movable stopping member. This inversion simplifies the wireless charger's internal structure while still enabling easy alignment operation.
Solution Approach 2:
The stopping member is designed to automatically guide the electronic device into the correct position when placed on the wireless charger. The user simply needs to place the device, and the stopping member self-adjusts to provide the correct alignment, eliminating the need for complex moving mechanisms or manual adjustment procedures.
3Loss of time
If the electronic device displays a marking symbol to align with the wireless charger, then alignment time is reduced, but the electronic device requires built-in software and detection circuits increasing unit price
Solution Approach 1:
The patent replaces the expensive software and detection circuit solution with a simple, low-cost visual marking symbol that can be displayed on the electronic device's existing screen. This marking symbol is a simple graphical element rather than a complex detection system, significantly reducing the added cost while still achieving fast alignment.
4Productivity
If the electronic device is moved and adjusted every time for correct alignment, then charging efficiency is improved, but the process is time consuming and inconvenient
Solution Approach 1:
The stopping member is pre-positioned on the wireless charger to define the correct alignment position before the electronic device is placed. This preliminary positioning action eliminates the need for post-placement adjustment, allowing the device to achieve optimal charging efficiency immediately upon placement without time-consuming manual alignment.
