Earbud Charging Case Magnetic Bracket for Connector Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional earbud charging storage cases fail to achieve full contact between the first charging connector and the earbud charging connector due to upward resilience, resulting in incomplete charging.
Innovation Solution
The earbud charging storage case incorporates a magnetic component bracket with misaligned magnetic components that generate a downward magnetic attraction force, ensuring the earbud charging connectors resist resilience forces and maintain full contact for effective charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the first charging connector is equipped with upward resilience to ensure contact, then the connector can maintain contact pressure, but the upward resilience prevents full contact with the earbud charging connector
Solution Approach 1:
The patent replaces the mechanical resilient contact system with a magnetic field-based contact system. Magnetic components are embedded in the charging case and earbuds, creating magnetic attraction forces that pull the charging connectors into full contact without requiring mechanical resilience. This substitution eliminates the contradiction by using a different physical mechanism (magnetic force) instead of mechanical spring pressure.
Solution Approach 2:
The patent changes the fundamental parameter of contact force from mechanical resilience (elastic deformation) to magnetic attraction force. By embedding magnetic components and adjusting their strength and positioning, the system achieves both full contact precision and reliable contact maintenance through magnetic field parameters rather than mechanical spring parameters.
2Force
If the first charging connector uses mechanical resilience to maintain contact pressure, then contact pressure is ensured, but full contact with the earbud connector cannot be achieved
Solution Approach 1:
The patent substitutes mechanical spring pressure with magnetic attraction force. The magnetic components create a pulling force that draws the charging connectors together, simultaneously ensuring both full contact alignment and sufficient contact pressure for reliable electrical connection, eliminating the trade-off between force and precision.
3Device complexity
If conventional charging connectors are used without magnetic components, then the structure is simple, but full contact between charging connectors cannot be achieved
Solution Approach 1:
The patent introduces magnetic components into the charging connectors, replacing simple mechanical contact structures with magnetically-actuated contact mechanisms. This addition of magnetic elements enables full contact precision while maintaining relatively simple overall structure, as the magnetic field automatically handles the alignment and contact pressure without complex mechanical adjustment mechanisms.

AI summary
An earbud charging storage case for storing and charging a pair of earbuds, includes an earbud holder, and a magnetic component bracket looped around the earbud holder. Each earbud has a magnetic element. The earbud holder has a base portion. Two sides of a bottom surface of the base portion protrude downward to form two accommodating portions. Two sides of a top surface of the base portion are recessed downward to form two lower receiving grooves. The two accommodating portions have two accommodating grooves. The two lower receiving grooves and the two accommodating grooves together define two storing grooves. The pair of the earbuds are accommodated in the two storing grooves. Several portions of a bottom surface of the magnetic component bracket are recessed upward to form a plurality of buckling grooves. Each of the plurality of the buckling grooves is equipped with a first magnetic component.
