Solution Overview

Problem

Existing pipe coupling systems are complex, prone to leakage, and costly due to multiple parts, which complicates assembly and increases the risk of corrosion and oxidation, especially in harsh marine environments with varying temperatures and pressures.

Innovation Solution

A simplified coupling system comprising two pieces: a bracket with a gripping part, external threaded part, and split, and a nut with internal threads, made of plastic materials like polyoxymethylene or polypropylene, allowing easy assembly and disassembly without welding or soldering, and eliminating cavities and leakage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple parts (nut, body, gripping member, seal, washer) are used to ensure reliable pipe connection, then connection reliability is improved, but device complexity and assembly difficulty increase

Engineering Contradiction:
Improveconnection reliabilityVSAvoidnumber of parts
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple separate components (grip ring, wedge ring, seal) into an integrated coupling body with integrated gripping elements and sealing mechanisms. This merging reduces the total number of parts while maintaining the functional reliability of the connection through the unified structure's ability to withstand stresses and prevent leakage.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The coupling body is designed to perform multiple functions simultaneously: it provides gripping force through integrated gripping elements, creates sealing through integrated sealing mechanisms, and withstands mechanical stresses. This multi-functionality eliminates the need for separate dedicated components for each function, reducing overall complexity.

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

2Reliability

If multiple parts are used to ensure reliable connection, then connection integrity is improved, but assembly time and mounting difficulty increase

Engineering Contradiction:
Improveconnection integrityVSAvoidassembly time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

By integrating gripping elements, sealing mechanisms, and stress-withstanding structures into a single coupling body, the assembly process is simplified to installing one component rather than assembling multiple separate parts, significantly reducing assembly time while maintaining connection integrity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The coupling body is pre-designed and pre-assembled with all necessary functional elements (gripping surfaces, sealing lips, reinforcement structures) already in their correct positions and configurations, eliminating the need for on-site assembly of multiple components and reducing mounting time.

Inventive Principle:
Principle #10Preliminary action

3Strength

If metal pieces are used in coupling, then structural strength is improved, but corrosion and oxidation resistance deteriorate

Engineering Contradiction:
Improvestructural strengthVSAvoidcorrosion and oxidation
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The coupling employs composite construction combining metal elements for structural strength with protective coatings or corrosion-resistant materials for environmental protection. This composite approach allows the coupling to withstand mechanical stresses while resisting corrosion and oxidation in harsh environments.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent applies protective coatings or uses corrosion-resistant materials that create an inert or protective environment around the metal components, preventing direct contact with corrosive elements in the environment while maintaining the structural strength of the metal framework.

Inventive Principle:
Principle #39Inert atmosphere (Inert environment)

4Strength

If conventional securing techniques (welding, soldering) are used, then connection strength is improved, but ease of disassembly deteriorates

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

Solution Approach 1:

The coupling is designed as a segmented, modular system with the coupling body and connected pipes as separate components that can be easily assembled and disassembled. The integrated gripping elements and sealing mechanisms are designed to maintain strong connections during use while allowing for straightforward separation when needed, eliminating the permanent bonding required by welding or soldering.

Inventive Principle:
Principle #1Segmentation
