Solution Overview

Problem

Internal pipe connectors often fail to accommodate manufacturing variances in pipe diameters, leading to loose or tight connections, and are more expensive to produce than external connectors, making external connectors more commonly used despite aesthetic drawbacks.

Innovation Solution

A connector design featuring one or more flexible portions that can bend to accommodate varying pipe diameters, providing a friction fit and potentially reducing manufacturing complexity and costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If internal connectors are used to connect pipes, then the connection is structurally sound, but the connector does not accommodate manufacturing variances in pipe diameters leading to loose or tight connections

Engineering Contradiction:
Improveconnection securityVSAvoidaccommodation of diameter variance
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The connector incorporates flexible arms that can dynamically adjust their position and angle to accommodate variations in pipe diameter. The arms are designed with sufficient flexibility to bend and adapt to different pipe sizes while maintaining a secure friction fit, resolving the contradiction between connection reliability and adaptability to diameter variance.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If internal connectors are manufactured to accommodate pipe variance, then adaptability improves, but manufacturing complexity and cost increase due to requiring multiple parts and diverse manufacturing steps

Engineering Contradiction:
Improveaccommodation of diameter varianceVSAvoidnumber of parts and assembly steps
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The invention merges multiple functional elements into a single integrated connector body. The connector includes a central body with multiple arms extending from it, where each arm can independently flex to accommodate pipe variance. This unified structure eliminates the need for multiple separate parts and complex assembly steps, reducing manufacturing complexity while maintaining adaptability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The connector is segmented into multiple flexible arms that can independently adjust to different pipe diameters. Each arm acts as an independent element that can flex and adapt, allowing the connector to handle variance in pipe sizes without requiring a completely different connector design for each size variation.

Inventive Principle:
Principle #1Segmentation

3Ease of manufacture

If external connectors are used to connect pipes, then manufacturing cost is reduced, but the aesthetic quality of the junction deteriorates

Engineering Contradiction:
Improvemanufacturing costVSAvoidaesthetic quality of junction
Core Design Contradiction:
Ease of manufactureVSShape

Solution Approach 1:

Instead of using an external connector that attaches to the outside of pipes, the invention inverts the approach by using an internal connector that inserts into the pipes from the outside. The flexible arms extend into the pipe interior and secure the connection from within, making the connector hidden and preserving the aesthetic appearance of the pipe junction while maintaining cost-effectiveness.

Inventive Principle:
Principle #13The other way round (Inversion)
