Solution Overview

Problem

Existing fluid conduit couplings often create abrupt diameter changes, leading to flow resistance and poor performance over long runs due to their design for single industry standards.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If existing couplings are designed for single industry standards with abrupt diameter changes, then manufacturing simplicity is improved, but flow resistance increases and performance deteriorates

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidflow resistance
Core Design Contradiction:
Ease of manufactureVSLoss of energy

Solution Approach 1:

The adapter employs a tapered inner wall design that creates a curved, gradual transition between different diameters rather than an abrupt step change. This curvature allows fluid to flow smoothly through the transition zone, reducing turbulence and energy loss while maintaining ease of manufacture through standard tapering processes.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The adapter changes the geometric parameter of the inner wall from a stepped configuration to a tapered configuration. This parameter change transforms the abrupt diameter transition into a gradual one, reducing flow resistance and improving fluid dynamics while remaining manufacturable using conventional techniques.

Inventive Principle:
Principle #35Parameter changes

2Device complexity

If existing couplings create abrupt changes in diameter, then device complexity is reduced, but flow performance deteriorates over long runs

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The tapered inner wall introduces a curved transition geometry that improves fluid flow performance by eliminating abrupt changes. This curved design maintains relatively simple device structure while significantly enhancing flow characteristics over long conduit runs.

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Loss of energy

If adapter inner wall is tapered to provide gradual transition, then flow resistance is reduced, but manufacturing precision requirements increase

Engineering Contradiction:

Solution Approach 1:

The taper angle and transition length are optimized to balance flow performance benefits with manufacturability. By selecting appropriate parameter ranges, the design achieves significant flow resistance reduction while remaining compatible with standard manufacturing tolerances and processes.

AI summary

A system includes an adapter configured to provide an interface between a first fluid conduit and a second fluid conduit. The adapter has an inner wall and an outer wall. The adapter has a first end configured to fit against a first inside wall of the first fluid conduit. The adapter also has a second end configured to fit against a second inside wall of the second fluid conduit. The inner wall of the adapter has a first curvilinear transition from a first inside diameter at a first opening of the first end to an intermediate diameter between the first and second ends. The inner wall of the adapter has a second curvilinear transition from a second inside diameter at a second opening of the second end to the intermediate diameter.
