Solution Overview

Problem

Conventional pipe and hose connections require significant machining effort and material usage due to the need for flanges, which is inefficient and wasteful.

Innovation Solution

The introduction of an annular groove in the pipe socket allows for a releasable stop, such as an open ring, to be inserted for hose connection, reducing material loss and machining effort, enabling the pipe to be produced from a semi-finished state with minimal processing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If flanges are formed on the pipe ends, then the hose connection structure is stable and reliable, but material consumption and machining effort increase significantly

Engineering Contradiction:
Improvehose connection stabilityVSAvoidmaterial consumption
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The invention extracts the stop function from the pipe structure itself (flanges) and separates it into a detachable stop element. The pipe end is left without flanges, and the stop function is provided by a separate component that can be inserted into an annular groove, thereby reducing material consumption while maintaining connection stability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention segments the hose connection system into distinct functional components: the pipe with annular groove, the detachable stop element, and the hose. This segmentation allows the pipe to be produced without flanges (reducing material and machining), while the stop element provides the necessary positioning function when needed.

Inventive Principle:
Principle #1Segmentation

2Reliability

If flanges are formed on the pipe ends, then the hose connection structure is stable and reliable, but machining effort increases significantly

Engineering Contradiction:
Improvehose connection stabilityVSAvoidmachining effort
Core Design Contradiction:
ReliabilityVSEase of manufacture

The pipe end is left without flanges, and the stop function is provided by a separate component that can be inserted into an annular groove, thereby reducing material consumption while maintaining connection stability.

This segmentation allows the pipe to be produced without flanges (reducing material and machining), while the stop element provides the necessary positioning function when needed.

Inventive Principle:
Principle #1Segmentation

3Loss of substance

If a detachable stop element is used instead of flanges, then material consumption and machining effort are reduced, but the complexity of the connection system increases

Engineering Contradiction:
Improvematerial consumptionVSAvoidconnection system complexity
Core Design Contradiction:
Loss of substanceVSDevice complexity

Solution Approach 1:

The detachable stop element serves multiple functions: it provides the stop function for hose positioning, can be inserted into the annular groove for secure positioning, and can be removed and reused for subsequent hose connections. This multi-functionality justifies the added complexity by providing versatility and reusability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The stop element is designed to be discarded after one use and can be recovered and reused for subsequent hose connections. This recoverability reduces overall material consumption and justifies the additional component complexity by providing economic and environmental benefits.

Inventive Principle:
Principle #34Discarding and recovering

AI summary

The pipe and hose connection comprises a pipe (1), which has a pipe socket (3) that is integrally formed on the pipe on at least one end, a hose (4) being pressed thereon. The pipe socket (3) is separated from the pipe (1) by an annular groove (5), into which a stop is detachably inserted, which is preferably formed by an open ring (6). Said stop is inserted in the groove during the pressing operation of the hose and removed again after the pipe and hose connection has been created. The pipe can be produced with reduced loss of material and minimized machining from semi-finished pipes.
