Hermaphroditic Connector Asymmetric Key Prevents Rotation

Solution Overview

Problem

Existing electrical connectors require two separate types (male and female) to achieve mechanical and electrical coupling, which can lead to misconnection issues, especially with sensitive electronic equipment, and are prone to rotational movement and damage.

Innovation Solution

A hermaphroditic electrical connector design featuring a cage-like structure with a male contact prong and female contact socket, allowing for simultaneous mechanical and electrical connection without the need for end switching, and incorporating a latching mechanism for secure alignment and insulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional male and female connectors are used separately, then mechanical and electrical coupling can be achieved, but misconnection issues occur especially with sensitive electronic equipment

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent combines both male contact prong and female contact socket into a single connector body, creating a unified connector that integrates functions previously separated into two different connectors. This merging eliminates the need for matching male-female pairs and prevents misconnection by ensuring only identical connectors can mate together.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The connector is designed to perform multiple functions: it provides both male contact (prong) and female contact (socket) capabilities within a single device. This universal design allows the same connector type to be used on both sides of a connection, enhancing versatility and eliminating the need for different connector types.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Stability of the object's composition

If traditional male and female connectors are used, then connections can be formed, but rotational movement and damage occur

Engineering Contradiction:
Core Design Contradiction:
Stability of the object's compositionVSStrength

Solution Approach 1:

The connector incorporates an asymmetric design with a square key on one connector that fits into a corresponding square recess on the mating connector. This asymmetric feature prevents rotational movement by ensuring only one orientation allows proper engagement, thereby stabilizing the connection and preventing damage from improper alignment.

Inventive Principle:
Principle #4Asymmetry

3Productivity

If end switching is required for traditional connectors, then connections can be made, but time is lost and complexity increases

Engineering Contradiction:
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The connector design is self-aligning and self-mating, requiring no manual switching or orientation changes by the user. The asymmetric key-and-recess feature automatically guides the connectors into the correct orientation during insertion, eliminating the need for end switching and reducing both time and operational complexity.

Inventive Principle:
Principle #25Self-service
