Solution Overview

Problem

Existing mechanical connection interfaces for fiber optic components and structures, such as fiber management trays, are not intuitive or efficient for connecting and releasing components, often requiring complex latch mechanisms and direct pressing, which can be cumbersome.

Innovation Solution

A mechanical connection interface that allows a latch to be flexed by lateral movement of the component, enabling easy interlocking and releasing without initial latch deflection, using a first connection interface arrangement with a groove and enlarged portion, and a second interface arrangement with interlocks and stops for secure coupling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional latch mechanism is used requiring direct pressing to activate, then the latching function is achieved, but the ease of operation deteriorates due to cumbersome activation process

Engineering Contradiction:
Improveease of connecting and releasing componentsVSAvoidcomplexity of latch mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

Instead of requiring direct pressing of the latch to activate it, the patent inverts the mechanism so that lateral movement of the component body automatically activates the latch. The groove and enlarged portion are positioned such that sliding the component laterally causes the latch to engage with the interlock, transforming a complex pressing action into a simple sliding motion.

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

Solution Approach 2:

The latch mechanism is designed to be self-activating through the lateral movement of the component itself. The groove portion and enlarged portion work together with the interlock such that the component's own movement triggers the latching action without requiring separate manual intervention to press or activate the latch separately.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If latch activation requires initial deflection before sliding, then secure latching is achieved, but the ease of operation worsens due to multi-step activation process

Engineering Contradiction:
Improveintuitiveness of coupling processVSAvoidtime required for coupling operation
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent merges the lateral sliding movement with the latch activation into a single unified action. The groove portion is configured so that as the component slides laterally into position, the enlarged portion automatically engages the interlock, combining what would traditionally be separate actions (sliding and latching) into one simultaneous motion.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The groove and enlarged portion are pre-configured in specific positions and orientations so that when the component is laterally moved into the flush configuration, the latch activation is automatically triggered at the precise moment of engagement, eliminating the need for preliminary manual deflection of the latch before sliding.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If a secure interlocking mechanism is implemented, then the reliability of connection is improved, but the ease of operation deteriorates due to difficulty in releasing

Engineering Contradiction:
Improvesecurity of component connectionVSAvoidease of releasing component
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The release mechanism is inverted so that lateral movement in the opposite direction automatically triggers unlatching. The groove portion and enlarged portion are designed such that sliding the component laterally outward causes the interlock to disengage, transforming the release action from a complex manual operation into a simple reverse sliding motion.

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