Solution Overview

Problem

Existing pressure fittings for material flows in industrial piping systems are challenging to test for material defects due to complex geometries, leading to costly and time-consuming inspections.

Innovation Solution

A pressure fitting design with material interruptions between its components, such as a base body and pressure-reducing unit, allowing separate examination of individual parts before assembly, using molded parts and avoiding castings and forgings to facilitate easier testing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If pressure fittings are designed as integrated components with complex geometries, then functional performance is improved, but material testing becomes more difficult and costly

Engineering Contradiction:

Improvematerial qualityVSAvoidgeometry complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The pressure fitting is divided into separate components (base body and pressure-reducing unit) that are manufactured independently and then assembled. This segmentation allows each component to be tested separately using standard testing procedures, avoiding the difficulty of testing complex integrated geometries while maintaining the functional performance of the complete assembly.

Inventive Principle:

Principle #1Segmentation

2Strength

If pressure fittings are manufactured as single integrated parts, then structural integrity is improved, but inspection and testing time increases

Engineering Contradiction:

Improvestructural integrityVSAvoidtesting time

Core Design Contradiction:

StrengthVSLoss of time

Solution Approach 1:

The pressure fitting consists of a base body and a pressure-reducing unit that are manufactured separately and assembled together. Each component can be inspected and tested independently using standard procedures, significantly reducing the total testing time compared to inspecting a single complex integrated part, while the assembly creates sufficient structural integrity for the application.

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If complex geometric structures are used in pressure fittings, then functional capabilities are improved, but testing and inspection costs increase

Engineering Contradiction:

Improvefunctional capabilityVSAvoidtesting cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The pressure fitting is segmented into a base body and a pressure-reducing unit with relatively simple geometries that can be manufactured and tested separately using standard, cost-effective testing methods. This avoids the need for expensive specialized testing equipment required for complex integrated geometries, while the assembled components deliver the required functional capabilities.
