Spherical Connector Design for Efficient Charging and Data Transfer
Here’s PatSnap Eureka !
Summary
Problems
The existing charging and data transmission interfaces of mobile terminals, primarily relying on USB ports with few contacts and single functions, are inadequate for efficient current transmission and large-flow data transfer.
Innovation solutions
A female connecting member with multiple contacts arranged in grooves and a male connecting member with corresponding contact pieces, both equipped with springs, allowing for enhanced contact engagement and disengagement to improve transmission efficiency when connected.

General conflict description:
Principle concept:
If USB port with few contacts is used, then device complexity is reduced, but transmission efficiency of current or data deteriorates
Why choose this principle:
The patent transitions from a traditional planar USB connector interface to a three-dimensional spherical connector interface. The male connector features a spherical outer surface with contact pieces distributed across its surface, while the female connector has a corresponding spherical inner surface with contact dots. This dimensional change from 2D to 3D space allows for a significant increase in the number of contacts (from typically 4-9 in USB to 16 or more in the spherical design) without proportionally increasing the connector's physical footprint, thereby improving transmission efficiency while managing device complexity.
Principle concept:
If USB port with few contacts is used, then device complexity is reduced, but transmission efficiency of current or data deteriorates
Why choose this principle:
The spherical connector surface is segmented into multiple discrete contact points distributed across the sphere. The male connector divides its contact interface into multiple contact pieces (e.g., 16 contact pieces arranged in 4 rows with 4 contacts each), and the female connector similarly segments its interface into contact dots. This segmentation allows each contact to be independently positioned and connected, enabling high-density contact arrangements that improve current and data transmission capacity while maintaining a compact overall structure.
