Solution Overview

Problem

In modular construction, connecting pipework on-site is inefficient, requiring multiple steps and potentially leading to incorrect orientations and leaks, as plumbers need to manually attach and secure multiple pipe fittings.

Innovation Solution

A pipe interconnector system comprising engageable and disengageable parts with tubular protrusions and recesses, O-ring seals, and a locking mechanism, allowing for pre-assembly off-site and easy on-site connection, preventing incorrect orientations, and ensuring secure fluid passage without direct contact with the main bodies, thus reducing on-site labor and minimizing leaks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional manual pipe connection methods are used on-site, then plumbing connections can be made, but the process is time-consuming and labor-intensive requiring multiple steps for each pipe connection

Engineering Contradiction:
Improveplumbing connection speedVSAvoidon-site assembly time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The pipe interconnector components are prepared and configured in advance during off-site manufacturing. Multiple pipe receiving portions are pre-positioned on each part, and the correct orientation and configuration are established before delivery to the construction site. This preliminary preparation significantly reduces on-site assembly time and labor requirements.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention combines multiple pipe connection functions into a single integrated interconnector assembly. By merging multiple pipe receiving portions into one unit, the system allows simultaneous connection of multiple pipes through a single engagement action, rather than requiring separate connection steps for each pipe.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If multiple pipe fittings are manually attached and secured on-site, then pipe connections are achieved, but the complexity of the connection process increases and potential for errors rises

Engineering Contradiction:
Improveconnection accuracyVSAvoidconnection process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The pipe interconnector system is divided into two separable parts that can be independently handled and positioned. Each part has specific pipe receiving portions, allowing for modular assembly. This segmentation simplifies the connection process by breaking it into manageable stages while maintaining overall system integrity and reducing the chance of errors.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The first and second parts of the interconnector are designed with asymmetric features including specific tubular protrusions and corresponding recesses. This asymmetry ensures correct orientation and prevents incorrect assembly, as the parts can only be engaged in the proper configuration. The asymmetric design eliminates the possibility of wrong connections while simplifying the assembly process.

Inventive Principle:
Principle #4Asymmetry

3Reliability

If simple engagement mechanisms are used, then assembly is easy, but sealing and leak prevention become difficult to ensure

Engineering Contradiction:
Improvesealing effectivenessVSAvoidassembly simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

An O-ring seal acts as an intermediary element between the first and second parts of the interconnector. This sealing component is positioned within the engagement interface, creating a fluid-tight barrier without complicating the overall engagement mechanism. The O-ring accommodates minor dimensional variations while maintaining simplicity in the assembly process.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The O-ring seal is a flexible elastomeric component that deforms to conform to the engagement surfaces between the two parts. This flexibility allows the seal to effectively prevent leaks while accommodating manufacturing tolerances and assembly variations, maintaining both sealing effectiveness and ease of operation.

Inventive Principle:
Principle #30Flexible shells and thin films

4Adaptability or versatility

If the main bodies directly form fluid passageways, then the structure is simpler, but material selection is limited to fluids-compatible materials and pressure testing is required

Engineering Contradiction:
Improvematerial selection rangeVSAvoidpassageway structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The fluid passageways are extracted from the main bodies and formed as separate, distinct components. This allows the main bodies to be manufactured from a wide range of materials based on structural requirements rather than being constrained to fluid-compatible materials. The passageway components can be separately tested and certified for fluid contact, while the main bodies focus on mechanical strength and engagement functionality.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A pipe interconnector (1) comprises a male part (2) which has two pipe receiving portions (10, 11), and a female part (3) which has two pipe receiving portions (12, 13). The male and female parts (2, 3) are engageable with and disengageable from each other. Engagement of the male and female parts (2, 3) forms two passageways for fluid from the pipe receiving portions (10, 11) to the pipe receiving portions (12, 13).
