Solution Overview

Problem

Densely mounted optical connectors require complex and poorly workable cleaning processes due to the need for individual replacement of cleaning tools and precise alignment, leading to inefficiencies in cleaning multiple connectors simultaneously.

Innovation Solution

A cleaning tool with an adhesive portion that can contact and be easily replaced across multiple optical connectors, featuring a detachable design and enhanced flange structure to prevent adhesive residue on connector endfaces, improving workability and reducing signal loss.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If cleaning tools are provided for each optical connector hole to clean multiple connectors simultaneously, then cleaning efficiency is improved, but individual replacement of each cleaning tool makes the process complicated and workability poor

Engineering Contradiction:
Improvecleaning efficiencyVSAvoidworkability
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

Multiple cleaning tools are integrated into a single unit with a common handle, allowing simultaneous cleaning of multiple optical connector holes. The plurality of cleaning tools (including adhesive portions and flange portions) are combined structurally so that one replacement operation cleans multiple connectors at once, resolving the contradiction between cleaning efficiency and operational simplicity.

Inventive Principle:
Principle #5Merging (Combining)

2Manufacturing precision

If cleaning tools are aligned precisely for densely-mounted optical connectors, then cleaning accuracy is improved, but the precise operation required makes the entire replacement process complicated

Engineering Contradiction:
Improvealignment precisionVSAvoidreplacement complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The cleaning tool unit is designed with a universal structure where the handle portion accommodates multiple cleaning tools with different configurations. The common handle serves multiple functions: holding multiple adhesive portions, providing structural support, and enabling simultaneous insertion into multiple connector holes, thereby simplifying the replacement process while maintaining alignment precision.

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

3Productivity

If adhesive portion is used for cleaning multiple connectors collectively, then cleaning capability is improved, but adhesive residue may remain on connector endfaces causing signal loss

Engineering Contradiction:
Improvecleaning capabilityVSAvoidsignal loss
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The flange portion is extracted as a separate functional element from the adhesive portion. The flange acts as a protective barrier that prevents the adhesive portion from directly contacting the optical connector endfaces. This extraction allows the adhesive to clean connectors collectively while the flange removes potential harmful adhesive residue, thus maintaining both cleaning capability and signal integrity.

Inventive Principle:
Principle #2Taking out (Extraction)
