Earphone Charging Case Multipole Magnet Positioning Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing earphone boxes have low space utilization, large volume, and are inconvenient to carry due to single-point positioning of earphones, which leads to unstable charging and limited placement modes.
Innovation Solution
The earphone box incorporates a multipole magnet on the box body and an earphone magnet with the same number of poles, providing multi-point positioning and attraction, allowing the earphone to be placed obliquely, thus improving space utilization and stability during charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If single-point positioning is used to place the earphone in the box, then the structure is simple, but the positioning effect is poor and charging stability is reduced
Solution Approach 1:
The patent divides the single positioning point into multiple positioning points by using multipole magnets with multiple poles. Each pole creates an independent magnetic attraction point, transforming a single-point positioning system into a multi-point positioning system, thereby improving positioning accuracy and charging stability without requiring complex mechanical structures
Solution Approach 2:
The patent replaces complex mechanical positioning structures with a magnetic field-based positioning system. By using multipole magnets, the system achieves precise positioning through magnetic attraction forces rather than mechanical constraints, simplifying the overall structure while improving reliability
2Volume of stationary object
If the earphone box is designed with traditional single-point positioning, then the design is simple, but the space utilization is low and volume is large
Solution Approach 1:
The patent segments the magnetic field into multiple poles arranged in specific patterns, allowing the earphone to be positioned more efficiently within the box cavity. This multi-point magnetic positioning enables better space utilization by reducing empty space and optimizing the arrangement of components within the box
Solution Approach 2:
The patent changes the magnetic field distribution parameters by using multipole magnets with different pole configurations. This allows optimization of the magnetic attraction forces at different positions within the box, enabling compact design and reduced box volume while maintaining effective positioning
3Reliability
If the copper column and pogopin are oriented vertically to reduce dislocation, then charging reliability is improved, but the placement mode is limited
Solution Approach 1:
The patent replaces the gravity-dependent vertical orientation requirement with a magnetic field-based positioning system. The multipole magnets create attraction forces that can maintain proper alignment of charging contacts regardless of the earphone's placement orientation, enabling flexible placement modes while ensuring charging reliability
Solution Approach 2:
The patent creates a dynamic magnetic field configuration that can adapt to different placement orientations. The multipole magnet arrangement generates attraction forces that automatically adjust to maintain optimal contact between charging elements, allowing the system to accommodate various placement modes dynamically
