Solution Overview

Problem

Existing water management systems face challenges in creating a simple and efficient fluid connection between water-bearing arrangements and functional units in sanitary fittings, often requiring complex hose nipples and additional sealing components.

Innovation Solution

The solution involves a connecting hose with a shaped stopper on one end that directly attaches to the functional unit's hose intake, eliminating the need for a hose nipple. This design allows for a larger inner cross-section, reducing flow resistance, and incorporates a radially acting tank clamp for secure attachment and protection against shape instability due to heat.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a hose nipple is used to connect the connecting hose to the functional unit, then the connection is secure, but the internal cross-section is reduced and flow resistance increases

Engineering Contradiction:
Improveconnection securityVSAvoidflow rate
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The invention removes the hose nipple component entirely from the connection system. Instead of using a separate nipple piece that constricts the flow path, the connecting hose is equipped with an integrally formed retaining flange that hooks directly onto the hose receptacle of the functional unit, eliminating the need for a nipple and thus maintaining the full internal cross-section for water flow.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The retaining flange is formed in one piece with the connecting hose, merging the hose body and the connection element into a single integrated component. This eliminates the need for separate nipple and hose components, simplifying the assembly while maintaining both flow efficiency and connection security.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If a hose nipple and additional sealing components are used, then the connection is reliable, but the manufacturing process becomes complex

Engineering Contradiction:
Improveconnection reliabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The retaining flange is formed in one piece with the connecting hose through integral forming, combining multiple functions (hose body, connection element, and sealing surface) into a single component. This eliminates the need for separate nipple and sealing components, significantly simplifying the manufacturing process while maintaining connection reliability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrally formed retaining flange performs multiple functions simultaneously: it provides mechanical connection through the hook engagement, ensures sealing through the integrated sealing surface, and maintains structural integrity. This multi-functional design eliminates the need for multiple separate components.

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

3Productivity

If the connecting hose is made with a larger internal cross-section, then flow resistance is reduced, but the external dimensions or manufacturing complexity may increase

Engineering Contradiction:
Improveflow rateVSAvoidhose structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The retaining flange is formed in one piece with the connecting hose body, merging the hose structure and connection element into a single integrated component. This integral design allows the hose to maintain a larger internal cross-section for reduced flow resistance without adding separate complex components, as the connection structure is seamlessly integrated into the hose wall.

Inventive Principle:
Principle #5Merging (Combining)
