Solution Overview

Problem

Existing electrical connectors face challenges such as damage from accidental impact and difficulty in alignment, especially when one connector is obscured, like USB connectors on the backside of desktop computers.

Innovation Solution

The development of a self-orienting electrical connector with rotatable end pieces and magnetic alignment features, allowing for secure connection and easy alignment without requiring precise manual alignment, and using magnets to attract and repel for secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional physical insertion method is used, then electrical connection is established, but connector damage occurs from accidental impact and alignment difficulty arises

Engineering Contradiction:
Improveconnector durabilityVSAvoidalignment difficulty
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the traditional mechanical insertion system with a magnetic field-based system. Magnets embedded in both connectors generate magnetic attraction forces that automatically guide alignment and maintain connection, eliminating the need for precise manual alignment and providing impact resistance through magnetic holding force rather than mechanical friction.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The magnetic connectors perform self-alignment through magnetic attraction forces. When brought near each other, the magnets automatically guide the connectors into proper alignment without user intervention, and the magnetic force continuously maintains the connection, making the system self-correcting and self-sustaining.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If magnetic alignment features are added, then automatic alignment is achieved, but device complexity increases

Engineering Contradiction:
Improveautomatic alignmentVSAvoidconnector structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the magnetic alignment function with the connector housing itself. Magnets are embedded directly into the connector bodies, merging the alignment mechanism with the structural component rather than adding a separate alignment device. This integration minimizes additional complexity while achieving automatic alignment.

Inventive Principle:
Principle #5Merging (Combining)
