Connecting Hose Retaining Flange for Low-Resistance Water Flow
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
2Reliability
If a hose nipple and additional sealing components are used, then the connection is reliable, but the manufacturing process becomes complex
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.
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.
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
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.
