Solution Overview

Problem

Conventional connector assemblies require additional components or simultaneous actuation of both connectors for secure latching and unlatching, especially in hermaphroditic configurations, which complicates the process and increases the risk of accidental decoupling.

Innovation Solution

A compact single-end latching mechanism with a pivot arm and disengagement features allows for mechanical unlatching of hermaphroditic connectors from either end, using a linkage and actuating lever to move arms in opposite directions, disengaging retention features without needing simultaneous actuation of both connectors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional connector assemblies use additional components or simultaneous actuation for secure latching, then latching reliability is improved, but device complexity and ease of operation deteriorate

Engineering Contradiction:
Improvelatching reliabilityVSAvoidlatching mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines both retention features and disengagement features into a single integrated latching mechanism. The first and second retention features work together with the first and second disengagement features to provide secure latching while enabling simple single-end actuation. This merging eliminates the need for separate latching and unlatching mechanisms, resolving the contradiction between reliability and complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The latching mechanism is segmented into distinct retention features and disengagement features that can be independently analyzed but work together as a unified system. The first retention feature engages with the second retention feature, while the disengagement features provide separate actuation points, allowing the mechanism to achieve reliable latching through coordinated segments rather than a monolithic complex structure.

Inventive Principle:
Principle #1Segmentation

2Reliability

If conventional connector assemblies require simultaneous actuation of both connectors, then latching security is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvelatching securityVSAvoidunlatching operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

Instead of requiring actuation from both ends of the connector assembly, the patent inverts the approach by enabling actuation from a single end. The disengagement features are configured so that actuating one connector automatically triggers the release of both retention features through the mechanical linkage between the first and second disengagement features, simplifying operation while maintaining security.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent introduces an intermediary mechanical relationship between the first and second disengagement features. When one disengagement feature is actuated, it serves as an intermediary that triggers the corresponding movement in the other disengagement feature through the retention feature engagement, enabling coordinated unlatching from a single actuation point without requiring simultaneous action from both connectors.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Volume of moving object

If compact latching mechanism is used, then footprint is reduced, but latching reliability may deteriorate

Engineering Contradiction:
Improveconnector footprintVSAvoidlatching reliability
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The latching mechanism employs a nested arrangement where the first and second retention features are integrated within the connector housing, and the disengagement features are positioned to work within the same spatial envelope. This nesting allows the compact mechanism to maintain sufficient engagement strength and reliability while minimizing the overall footprint of the connector assembly.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent utilizes three-dimensional spatial arrangement of the retention and disengagement features to achieve compact dimensions. By orienting the retention features at opposite sides of the connector and positioning the disengagement features to engage them through lateral movement, the mechanism achieves reliable latching in a compact footprint by exploiting dimensional efficiency rather than requiring larger planar dimensions.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

A hermaphroditic connector configured to mate with a mating hermaphroditic connector includes a latching mechanism configured to mechanically unlatch the connector and a mating connector. The latching mechanism of the connector, when actuated to unlatch the connector and the mating connector, disengages both a retention feature of the connector and a retention feature of the mating connector.
