Solution Overview

Problem

In high-density connector configurations, it is difficult to extract a connector once it is plugged in due to inaccessible latching mechanisms, often requiring removal of adjacent modules or special tooling for access.

Innovation Solution

A module with a housing, a resilient latch, and an actuator with pivotally attached lateral flanges that allows rearward pulling to pivot and free the latch from its engagement, enabling easy extraction without disturbing adjacent modules or using special tooling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If connectors are densely packed in high-density configurations, then space utilization is improved, but accessibility to the latching mechanism deteriorates

Engineering Contradiction:
Improveconnector densityVSAvoidlatching mechanism accessibility
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The actuator is positioned on the side wall of the housing rather than on the top or bottom, utilizing the lateral dimension for actuation. This side-mounted position allows access to the latching mechanism from the side of the connector array, bypassing the blocking issue that occurs when connectors are stacked vertically in high-density configurations.

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

Solution Approach 2:

Instead of accessing the latching mechanism from the top or bottom of the connector (conventional approach), the invention inverts the access direction by providing actuation from the side wall. This reverse approach to latching mechanism access allows operators to engage and disengage connectors even when they are densely packed in vertical arrays.

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

2Ease of operation

If special tooling is used to access the latching mechanism, then connector extraction is enabled, but device complexity increases

Engineering Contradiction:
Improveconnector extraction capabilityVSAvoidtooling requirements
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The connector module provides self-service extraction capability through the integrated side-mounted actuator. The actuator is part of the connector housing itself, allowing operators to disengage connectors using the connector's own built-in mechanism rather than requiring external special tooling. This eliminates the need for separate extraction tools while maintaining the ability to remove connectors from dense arrays.

Inventive Principle:
Principle #25Self-service

3Volume of moving object

If the latching mechanism is located on the top or bottom of the connector, then structural compactness is improved, but operational accessibility deteriorates

Engineering Contradiction:
Improveconnector compactnessVSAvoidlatch actuation accessibility
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The actuator is repositioned from the top or bottom surface to the side wall of the housing, utilizing the lateral dimension for access. This spatial reconfiguration maintains the compact vertical profile of the connector while providing accessible actuation from the side, resolving the conflict between compactness and operational accessibility.

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

AI summary

A module (100) having a front/rear and top/bottom orientation comprises a housing (101) having front and rear ends. A connector (102) is at the front end of the housing (100) for interengaging with a mating connector having a purchase point. A resilient latch (103) has a secured end (104) secured to the housing (100), and a free end (105) forward of the secured end (104). The free end (105) is biased toward the housing (100) and is configured to releasibly engage the purchase point. An actuator (106) is moveably attached to the housing (101). The actuator (106) is disposed under the latch (103) and has a contact portion (107) which contacts the latch (103) as the actuator (106) is pulled rearward to urge the latch (103) away from the housing (101), thereby freeing the free end (105) from the purchase point.
