Spliced Alignment Magnetic Ring for Wireless Charger
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current magnetic wireless chargers for mobile phones lack accurate positioning and sufficient magnetic force, leading to unstable attraction and difficulty in aligning the phone for charging.
Innovation Solution
A spliced alignment magnetic ring with multiple magnetic groups arranged circumferentially on a ring base body, featuring first and second magnetic bodies with different polarities that magnetically attract each other, enhancing the magnetic field intensity and attraction force, and optionally including a bearing pedestal with accommodating slots for improved assembly and positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a single magnetic ring is used in the wireless charger, then the structure is simple, but the magnetic attraction force is insufficient and positioning accuracy is poor
Solution Approach 1:
The magnetic ring is divided into multiple magnetic groups (first magnetic group, second magnetic group, third magnetic group) with different polarities arranged at specific intervals. This segmentation creates multiple magnetic attraction points that work together to provide stronger overall magnetic force and more precise positioning capability, resolving the contradiction between simple structure and sufficient magnetic attraction.
2Measurement precision
If magnetic groups are arranged circumferentially with different polarities, then positioning accuracy improves, but manufacturing complexity increases
Solution Approach 1:
Different magnetic groups are assigned different polarities (first magnetic group: N pole, second magnetic group: S pole, third magnetic group: N pole) and arranged at specific circumferential intervals. This local differentiation of magnetic properties creates specific attraction and repulsion zones that guide precise phone positioning, while the systematic arrangement pattern keeps manufacturing manageable.

AI summary
The present disclosure discloses a spliced alignment magnetic ring of a wireless charger, including a ring base body and at least two magnetic groups. All the magnetic groups are disposed at an interval along a circumferential direction of the ring base body, and all the magnetic groups are arranged on the same side of the ring base body. In the spliced alignment magnetic ring of the wireless charger, the at least two magnetic groups are circumferentially disposed on the ring base body, and a magnetism sensor corresponding to the ring base body is arranged in a wireless charging sensing region on the mobile phone, so that the mobile phone can be automatically and accurately aligned for charging when being placed on the wireless charger.
