Solution Overview
Problem
Existing electrical connectors for electronic devices lack miniaturization capabilities and versatility, as they often require separate connectors for charging and switching functions, leading to increased size and cost in small electronic devices.
Innovation Solution
A dual-function electrical connector assembly comprising a first connector with a switch assembly and conductive members, and a second connector with magnetic attraction rings, allowing for 360-degree mating and charging, while integrating switch and charging functions in a single connector, facilitating miniaturization and reducing component count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate connectors are used for charging and switching functions, then functional reliability is improved, but device size and component count increase
Solution Approach 1:
The patent combines the charging function (conductive members) and switching function (switch assembly with button) into a single integrated connector structure. The insulating base houses both the switch assembly and conductive members, allowing one connector to perform multiple functions that previously required separate components, thereby reducing device size while maintaining functional reliability
Solution Approach 2:
The connector is designed with multi-functionality by incorporating both a switch assembly (with button for on/off control) and conductive members (for charging) within the same structural unit. This universal design allows the single connector to serve dual purposes: switching control and electrical charging, eliminating the need for separate dedicated connectors for each function
2Reliability
If magnetic attraction structure is used, then connection reliability is improved, but manufacturing complexity increases
Solution Approach 1:
The magnetic attraction system is segmented into two separate components: a first magnetic attraction ring in the first connector and a second magnetic attraction ring in the second connector. This segmentation allows each magnetic ring to be manufactured and assembled independently into its respective connector housing, simplifying the manufacturing process while maintaining the reliability benefits of magnetic attraction for connection stability
3Ease of operation
If 360-degree mating capability is implemented, then ease of operation is improved, but structural complexity increases
Solution Approach 1:
The connector employs asymmetric magnetic attraction ring placement and conductive member arrangement that enables 360-degree rotational compatibility. The first magnetic attraction ring is positioned on the outer circumference of the mating portion, allowing the connector to be inserted at any rotation angle while maintaining proper alignment through magnetic attraction, thereby achieving universal ease of operation without requiring complex alignment mechanisms
