Solution Overview

Problem

Existing solutions for connecting fire extinguishing agent containers to installed piping networks are costly, time-consuming, and prone to damage due to hydraulic lifting, requiring elaborate additional fittings and having limited durability.

Innovation Solution

A rigid, long-distance pipe connector with movable connecting pipes and a calotte joint that compensates for angular and length differences, using a trapezoidal thread and preload element to ensure stable and durable connection without additional fittings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a flexible hose adapter is used to connect the extinguishing agent container to the piping network, then angle and height compensation is possible, but the adapter is expensive and has limited lifespan

Engineering Contradiction:
Improveangle compensation capabilityVSAvoidadapter lifespan
Core Design Contradiction:
Adaptability or versatilityVSDuration of action of stationary object

Solution Approach 1:

The pipe connector incorporates articulated connections that enable dynamic angle compensation between the extinguishing agent container and the piping network. This allows the rigid connector to adapt to angular misalignments while maintaining structural integrity and durability, eliminating the need for flexible hoses with limited lifespans.

Inventive Principle:
Principle #15Dynamics

2Ease of manufacture

If cylindrical pipes are arranged to slide inside each other for connection, then assembly is simplified, but hydraulic pressure exerts tons of force on the pipeline network causing damage

Engineering Contradiction:
Improveconnection assembly simplicityVSAvoidpipeline network fastening strength
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The pipe connector is divided into multiple segments including a body section, a preloaded section with threaded connection, and articulated connection sections. This segmentation allows the hydraulic pressure forces to be distributed and absorbed by the articulated connections rather than transmitted to the pipeline network fastenings, maintaining both assembly simplicity and structural strength.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If additional fittings and complex piping are installed to adapt the piping network, then connection compatibility is improved, but construction effort and cost increase

Engineering Contradiction:
Improveconnection compatibilityVSAvoidpiping network complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The pipe connector is designed as a universal multi-functional component that combines angle compensation, length adjustment, and connection adaptation in a single device. This eliminates the need for multiple separate fittings and complex piping modifications, reducing both construction effort and overall system complexity while maintaining connection compatibility.

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