Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless charging is implemented without alignment detection, then charging convenience is improved, but charging efficiency deteriorates due to coil misalignment
Solution Approach 1:
The system provides real-time feedback by displaying alignment detection results on the screen, showing whether the electronic device is properly aligned with the charging base. This visual feedback enables users to adjust their placement to achieve optimal charging efficiency while maintaining the convenience of wireless charging.
Solution Approach 2:
The alignment detection module acts as an intermediary between the charging system and the user, providing objective measurement and visualization of alignment status. This mediator translates complex electromagnetic field interactions into simple visual indicators that guide user behavior.
2Productivity
If alignment detection is added to wireless charging, then charging efficiency is improved, but device complexity increases
Solution Approach 1:
The alignment detection system automatically measures and displays alignment status without requiring user intervention or complex manual calibration. The system serves itself by using its own electromagnetic fields to detect alignment, eliminating the need for external measurement tools or complex setup procedures.
Solution Approach 2:
The patent replaces complex mechanical alignment mechanisms with electromagnetic field-based detection. Instead of using physical guides, adjustable components, or mechanical feedback systems, the invention uses electromagnetic signals to detect and indicate alignment status, significantly reducing mechanical complexity.
3Device complexity
If coil alignment is not monitored, then device simplicity is maintained, but charging rate decreases due to misalignment
Solution Approach 1:
The system continuously monitors alignment status and provides visual feedback to users. This simple feedback mechanism enables users to self-correct misalignment issues, maintaining high charging rates without requiring complex automatic adjustment mechanisms or increasing device complexity.
Solution Approach 2:
The alignment detection system uses visual indicators (such as color changes or icon displays) to communicate alignment status to users. This simple visual language effectively guides users to achieve proper alignment and maintain optimal charging rates without adding mechanical or electronic complexity.

AI summary
This application relates to the field of wireless charging technologies, and discloses a wireless charging alignment detection method and an electronic device. A charging alignment picture is displayed on a screen of the electronic device, so that when a wireless charging base is not accurately aligned with the electronic device, that is, when the electronic device is not in a preferred charging position on the wireless charging base, a user can be prompted to adjust a position of the electronic device on the charging base of a wireless charger. In this way, the electronic device is in the preferred charging position on the wireless charger. When the electronic device is in the preferred charging position on the wireless charger, a charging rate for the electronic device is relatively high. This improves a charging rate of the wireless charger for the electronic device.
