Solution Overview

Problem

Existing fiber optic connector closures require additional fixing means, such as screws, for mounting and dismounting, leading to increased labor and equipment costs and a complex internal structure.

Innovation Solution

A waterproof push-pull closure that allows easy locking and unlocking of fiber optic connectors through forward and backward operations, utilizing a fiber optic connector locking device with a plunger mechanism and heart-cam structure, enabling sealing and detachment without additional devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If additional fixing means such as screws are used to secure the fiber optic connector, then the connector can be reliably fixed to the closure, but the operational complexity and labor requirements increase

Engineering Contradiction:
Improveconnector fixation reliabilityVSAvoidconnector mounting and dismounting ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The closure system performs the fixing function automatically through its own structure. The closure body includes an insertion hole with an internal fixing mechanism that self-secures the fiber optic connector when inserted, eliminating the need for separate screw-fixing operations by operators

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The fixing function is merged into the closure body itself rather than being a separate operation. The insertion hole is designed with integrated fixing features that combine the insertion and fixation functions into a single structural element, allowing the closure to fix the connector without additional fixing means

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If additional fixing means such as screws are used to secure the fiber optic connector, then the connector can be reliably fixed to the closure, but the equipment cost increases

Engineering Contradiction:
Improveconnector fixation reliabilityVSAvoidequipment manufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The separate screw-fixing components and operations are extracted from the system. The closure body is designed to provide all necessary fixing functionality through its inherent structure, removing the need for additional fixing means and reducing overall equipment costs

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The fixing function is merged into the closure body itself rather than being a separate operation. The insertion hole is designed with integrated fixing features that combine the insertion and fixation functions into a single structural element, allowing the closure to fix the connector without additional fixing means and reducing equipment costs

Inventive Principle:

AI summary

The present invention relates to a waterproof push-pull closure having a function of easily locking and unlocking a fiber optic connector, the closure enabling attachment/detachment on the outer periphery of an object to be provided, enabling waterproofing through a sealed structure, and fixing/releasing the fiber optic connector to/from the inside of the closure merely through forward and backward operations when the fiber optic connector insertion-coupled to the inside of the closure is inserted, thereby facilitating use.
