Solution Overview

Problem

Existing installation fittings for domestic water supply pipe systems, particularly those made from low-end synthetic polymers, face challenges in meeting maximum application class parameters, leading to reduced pipe tang flow cross sections and undesirable flow patterns due to increased thickness requirements for compliance with technical standards.

Innovation Solution

The use of a composite structure with a housing made from low-end synthetic polymer material and pipe tangs fitted with high-end material sockets, such as high-end synthetic polymers or metals, which act as protective barriers, allowing for a reduction in pipe tang thickness while maintaining compliance with technical standards and reducing costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If installation fittings are made entirely from low-end synthetic polymer material, then manufacturing cost is reduced, but pipe tang thickness must be increased to meet technical standards, which reduces flow cross section

Engineering Contradiction:

Improvemanufacturing costVSAvoidpipe tang flow cross section

Core Design Contradiction:

Ease of manufactureVSArea of stationary object

Solution Approach 1:

The patent applies composite materials by combining low-end synthetic polymer material for the housing with high-end material (metal or engineering plastic) sockets for the pipe tangs. This composite structure allows the pipe tangs to meet technical standards with reduced thickness while maintaining overall cost-effectiveness, as the expensive high-end material is used only where structurally critical.

Inventive Principle:

Principle #40Composite materials

2Strength

If pipe tang thickness is increased to meet technical standards, then strength and reliability are improved, but flow cross section is reduced leading to undesirable flow patterns

Engineering Contradiction:

Improvepipe tang strengthVSAvoidundesirable flow pattern

Core Design Contradiction:

StrengthVSObject-generated harmful factors

Solution Approach 1:

The patent applies local quality by using high-end materials specifically for the pipe tang sockets where strength is critical, while using low-end synthetic polymer material for the housing where structural demands are lower. This localized application of material properties achieves the required strength without unnecessarily reducing the overall flow cross section.

Inventive Principle:

Principle #3Local quality

3Reliability

If high-end material sockets are used in pipe tangs, then compliance with technical standards is achieved, but device complexity increases

Engineering Contradiction:

Improvecompliance with technical standardsVSAvoidcomposite structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the low-end synthetic polymer housing with high-end material sockets into a single integrated assembly. The sockets are fitted into the housing in a manner that combines the components into a unified structure that meets technical standards while managing complexity through integrated design.

Inventive Principle:

Principle #5Merging (Combining)
