Solution Overview

Problem

Existing double pipeline systems for transporting environmentally hazardous media lack modularity and ease of mechanical separation during expansion or conversion, limiting their adaptability and maintenance.

Innovation Solution

A system comprising two outer and two inner pipe connection elements with detachable connections using collar socket parts, union nuts, and collar bushing parts, allowing for modular design and easy separation, with features like non-return valves and through-holes for medium flow, enabling flexible adaptation to different tasks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If double pipeline systems use traditional rigid connection methods, then structural integrity is maintained, but ease of separation and modularity deteriorates

Engineering Contradiction:
Improveease of separationVSAvoidmodularity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The pipeline system is divided into modular segments with standardized connection elements. Outer pipe connection elements and inner pipe connection elements can be independently assembled and disassembled, allowing the pipeline to be separated into manageable sections for maintenance or expansion without compromising overall structural integrity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection system transitions from rigid permanent joints to dynamic reversible connections. Union nuts and collar socket parts enable the pipeline to be easily assembled and disassembled multiple times, providing operational flexibility while maintaining connection reliability through standardized threading and seating surfaces.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If double pipeline systems are designed for easy separation, then adaptability for expansion and conversion is improved, but structural integrity and reliability deteriorates

Engineering Contradiction:
ImproveadaptabilityVSAvoidstructural integrity
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The connection elements are designed with universal applicability across different pipeline configurations. The outer pipe connection elements and inner pipe connection elements can accommodate various pipe sizes and types while maintaining standardized threading and sealing interfaces, enabling easy adaptation for expansion or conversion while ensuring consistent structural reliability through proven connection designs.

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

Solution Approach 2:

Collar socket parts and union nuts serve as intermediary components between pipe sections. These mediators provide standardized interfaces that simplify connection and disconnection operations while distributing mechanical loads evenly, thereby maintaining structural integrity during repeated assembly and disassembly cycles.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of manufacture

If traditional connection components are used, then manufacturing simplicity is maintained, but ease of manufacture for modular components deteriorates

Engineering Contradiction:
Improveease of manufactureVSAvoidcomponent modularity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The fitting is segmented into distinct manufacturable components: outer pipe connection elements, inner pipe connection elements, collar socket parts, and union nuts. Each component can be manufactured independently using standardized processes, then assembled into the complete fitting assembly, simplifying manufacturing while achieving the desired modularity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple functional requirements are merged into integrated components. The outer pipe connection element combines threading, sealing surfaces, and structural support functions in a single manufacturable part, as does the inner pipe connection element, reducing the total number of parts while maintaining ease of manufacture and assembly.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The system (1) has an outer connecting element (10) flexibly connected with outer pipe connection elements (6, 7) using outer flange sleeves (14, 15) and outer union nuts (16, 17). Each outer pipe connection element has a stopper (18) at an outer circumference for the outer flange sleeves and another stopper (19) at an inner circumference for inner flange sleeves (8, 9). The outer pipe connection elements have a flow through opening (20) for a medium provided in a shell space (21) of a double pipe line system.
