Solution Overview

Problem

Existing optical connector construction tools are costly to manufacture, require multiple components, and fail to efficiently transmit visible light for visual confirmation of assembly, leading to potential wedge creep and increased material waste.

Innovation Solution

A compact, single-component optical connector construction tool featuring a V-grooved base plate and pressing lid with a clamp spring, and a pair of arms that support a wedge for reliable withdrawal and anchoring of optical fibers, constructed from creep-resistant transparent resin to prevent deformation and facilitate visual confirmation of successful connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a construction tool is constructed using multiple components (wedge and base), then the wedge can be securely anchored, but the manufacturing cost increases and the tool size increases

Engineering Contradiction:
Improvewedge anchoring reliabilityVSAvoidnumber of components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The wedge and base are merged into a single integrated construction tool component. The base plate includes an integrated wedge support structure that provides both support and anchoring functions without requiring a separate wedge component, thereby reducing component count while maintaining anchoring reliability

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The base plate serves multiple functions: it provides structural support, integrates the wedge support structure, and includes positioning protrusions that work with the optical connector. This multi-functionality eliminates the need for separate components while maintaining all necessary functions

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of manufacture

If a transparent material is used for the construction tool, then visual confirmation of assembly is enabled, but visible light transmission is insufficient

Engineering Contradiction:
Improvevisual confirmation capabilityVSAvoidvisible light transmission
Core Design Contradiction:
Ease of manufactureVSIllumination intensity

Solution Approach 1:

The base plate is made of transparent material specifically in the regions where visual confirmation is needed, while maintaining structural integrity in load-bearing areas. The wedge support structure and positioning protrusions are strategically positioned to allow light transmission paths for observing the mechanical splicing process

Inventive Principle:
Principle #3Local quality

3Device complexity

If flexible materials are used to allow lateral pressure deformation, then the tool can be constructed as a single component, but wedge creep occurs and the open state is not maintained

Engineering Contradiction:
Improvesingle component constructionVSAvoidwedge position stability
Core Design Contradiction:
Device complexityVSStability of the object's composition

Solution Approach 1:

The material properties of the base plate are selected to have appropriate rigidity and creep resistance characteristics. The material is chosen to maintain dimensional stability under lateral pressure while still allowing the necessary flexibility for single-component construction, preventing wedge creep and maintaining the open state

Inventive Principle:
Principle #35Parameter changes

4Ease of operation

If the construction tool is made large in size, then sufficient space is provided for operation, but material costs increase and the tool is not recyclable

Engineering Contradiction:
Improveoperational spaceVSAvoidmaterial waste
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

The construction tool is designed with a compact nested structure where components are arranged efficiently within a small footprint. The wedge support structure and positioning protrusions are integrated in a space-efficient manner, providing sufficient operational space while minimizing overall tool size and material usage

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

There is provided an optical connector construction tool, which is constructed as a single component, and is compact in size and simple, wherein the construction tool allows an operation of withdrawing a wedge to be more reliably performed, and a manufacturing costs to be reduced. The optical connector construction tool comprises a base plate, a wedge provided to a bottom surface of the base plate and inserted into a mechanical splice part of an optical connector, a pair of arms extending from both sides of the base plate, and protrusions projecting from the arms toward the base plate, the protrusions engaging with the bottom of the base plate and deflecting the base plate upward as a result of the arms being laterally brought together.
