Solution Overview

Problem

Existing pipe connectors are difficult to open and close quickly, prone to damage, and unreliable in maintaining a tight seal, especially when frequently used or with varying component diameters and angles.

Innovation Solution

A component connector featuring an elastic sleeve and a deformable fixing sleeve with opposing wedge surfaces and clamping rings that create a frictional and sealed connection, allowing for easy assembly and disassembly without adhesives or heat treatment, and protecting the sealing components from external damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If adhesive or cured bonding is used to connect pipe end faces, then connection strength is improved, but ease of disassembly deteriorates (cannot be easily opened without damaging components)

Engineering Contradiction:
Improveconnection strengthVSAvoidease of disassembly
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The connector is divided into separate functional elements: a first connector part with external threading and a second connector part with internal threading. These segments can be independently assembled and disassembled without damaging the pipe components, resolving the contradiction between strong connection and easy disassembly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A sealing element is introduced as an intermediary component between the pipe end faces and the connector. This sealing element can be easily removed and replaced, allowing the connector to be disassembled and reassembled multiple times without damaging the pipes or compromising the seal, thus enabling both strong connection and easy disassembly.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the connector structure is made accessible from outside for assembly, then ease of operation is improved, but reliability deteriorates (casing can be damaged, affecting tightness and preventing leakage prevention)

Engineering Contradiction:
Improveease of assemblyVSAvoidsealing reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The sealing element is nested within the connector structure, specifically positioned between the pipe end faces and the connector body. This nested arrangement protects the sealing element from external damage while still allowing easy access for assembly and disassembly through the connector's open structure, resolving the contradiction between ease of operation and sealing reliability.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Device complexity

If a simple connector structure is used, then device complexity is reduced, but adaptability deteriorates (cannot handle different diameters and angles)

Engineering Contradiction:
Improveconnector structure complexityVSAvoidadaptability to different diameters and angles
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The connector is designed with universal features including adjustable positioning elements that can accommodate pipes of different diameters and angles. The connector body includes guide surfaces and adjustment mechanisms that allow it to adapt to various pipe configurations without requiring complex specialized components, thus achieving both simplicity and versatility.

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