Solution Overview

Problem

Conventional central insertion connectors, while providing corrosion resistance, lack sufficient stiffness and strength, making them susceptible to damage and potential leaks due to their plastic material composition and uneven wall thickness.

Innovation Solution

A central insertion connector with a metallic main body unit coated with a corrosion-resistant layer, featuring a threaded connection section with a circumferential groove and an insertion section with a trough, where the layer forms retention portions to secure the coating and enhance structural integrity, combining with a metallic material for improved stiffness and strength.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a plastic material is used for the central insertion connector to achieve corrosion resistance, then corrosion resistance is improved, but stiffness and strength deteriorate

Engineering Contradiction:
Improvecorrosion resistanceVSAvoidstiffness and strength
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

The connector uses a composite structure combining plastic material with a metal reinforcement sleeve. The plastic provides corrosion resistance while the metal sleeve embedded within provides the necessary stiffness and strength, resolving the contradiction between these two properties through material composition.

Inventive Principle:
Principle #40Composite materials

2Ease of operation

If the wall thickness of the insertion section is reduced to accommodate the connector design, then ease of installation is improved, but structural strength deteriorates

Engineering Contradiction:
Improveease of installationVSAvoidstructural strength
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The metal reinforcement sleeve is specifically positioned at the insertion section where wall thickness is reduced. This composite construction allows the thin-walled plastic to be easily installed while the embedded metal sleeve compensates for the reduced thickness by providing the necessary structural strength.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The metal reinforcement sleeve is strategically placed only at the insertion section rather than throughout the entire connector. This local reinforcement provides strength exactly where needed (at the thin-walled insertion section) while maintaining ease of installation and not unnecessarily increasing complexity elsewhere.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If a thin-walled insertion section is used to facilitate connection, then ease of operation is improved, but reliability deteriorates due to susceptibility to cracking

Engineering Contradiction:
Improveease of connectionVSAvoidresistance to cracking
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The metal reinforcement sleeve is embedded within the thin-walled plastic insertion section, creating a composite structure. The thin plastic wall allows easy connection operations while the embedded metal sleeve prevents cracking and maintains reliability under operational stresses.

Inventive Principle:
Principle #40Composite materials

AI summary

The present invention relates to a central insertion connector. The central insertion connector (2) includes a main body unit (3) and a corrosion resistant layer (4) coated on and covering the main body unit (3). The main body unit (3) includes a penetrating flow channel (3a). The main body unit (3) at least includes a threaded connection section (31) and an insertion section (32) arranged opposite to the threaded connection section (31). Surfaces of the flow channel (3a), the threaded connection section (31), and the insertion section (32) of the main body unit (3) is coated with the corrosion resistant layer (4) so that on the one hand, the central insertion connector (2) is provided with an effect of corrosion resistance and on the other hand, overall stiffness and strength are improved, so as to enhance operation performance of the central insertion connector (2).
