Solution Overview

Problem

Existing fiber optic connector devices lack an efficient and user-friendly fixation and releasement mechanism, particularly in harsh environments, with snap-in units being cumbersome and requiring additional tools for operation.

Innovation Solution

A transmission connector device featuring a latching unit with a partially ring-shaped spring element, actuated by pulling along an axial direction, allowing for quick and tool-free latching and releasing, and incorporating a locking mechanism for enhanced security and ease of use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a snap-in unit with snap hitches is used for fixation, then the connection can be established, but the operation requires additional tools and is cumbersome

Engineering Contradiction:
Improveease of latching and releasingVSAvoidcomplexity of fixation mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The spring element is designed to automatically return to its initial state after deformation, enabling the latching unit to self-latch and self-release without requiring additional tools or complex actuation mechanisms. The elastic recovery of the spring element provides the necessary force for automatic engagement and disengagement.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The latching unit is divided into functionally independent components: the spring element for elastic deformation and recovery, the actuation unit for applying force, and the latching unit for engagement. This segmentation allows each component to be optimized independently while working together to provide tool-free operation.

Inventive Principle:
Principle #1Segmentation

2Volume of moving object

If a traditional latching mechanism is used, then fixation is achieved, but the mechanism is not compact and requires more space

Engineering Contradiction:
Improvecompactness of latching unitVSAvoidsecurity of connection
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The latching unit components are arranged in a nested configuration where the spring element is positioned within the actuation unit, and the latching unit engages within the plug-in housing. This nested arrangement minimizes the overall volume while maintaining the reliability of the connection through the integrated spring and latch mechanism.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Ease of operation

If additional tools are required for latching and releasing, then the mechanism can be robust, but the user comfort and ease of use are reduced

Engineering Contradiction:
Improveuser comfortVSAvoidsimplicity of mechanism
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The spring element provides automatic return to initial state, enabling tool-free operation. The actuation unit can be manually operated to deform the spring element, which then automatically engages or disengages the latching unit without requiring external tools, thereby improving user comfort while maintaining mechanism simplicity.

Inventive Principle:
Principle #25Self-service

AI summary

The invention is based on a transmission connector device (12a-b) comprising an actuation unit (16a-b) for actuating a latching unit (18a-b) by pulling along an axial direction (20a-b) and thereby transferring the latching unit (18a-b) from a latch position into a release position. For the purpose of providing a transmission connector device with improved characteristics regarding a fixation and/or releasement mechanism, comfort and/or construction, it is proposed that the latching unit (18a-b) comprises an at least partially ring-shaped spring element (21a-b).
