Sanitary Fitting Pivotable Hose Adapter Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sanitary fittings with single-lever mixing cartridges face challenges in efficiently routing and connecting hoses due to direct contact with metallic surfaces and complex assembly processes, particularly when integrating with commercially available cartridges.
Innovation Solution
A sanitary built-in part with a pivotably attached connecting piece and an adapter piece featuring askew connecting passages allows for easy assembly and adaptation to different cartridges, enabling the routing of hoses while maintaining a secure and sealed connection, and incorporating a flexible connecting hose for improved mobility and installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-lever mixing cartridge is integrated into a sanitary fitting, then the mixing function is improved, but the assembly complexity and hose routing difficulty increase
Solution Approach 1:
The connecting piece is divided into multiple functional sections: a base plate mounting section, a pivoting connection section for the cartridge, and a hose connection section. This segmentation allows each part to be optimized independently while simplifying the overall assembly process.
Solution Approach 2:
The connecting piece acts as an intermediary component between the cartridge and the hose assembly. It mediates the connection by providing a pivoting mechanism that accommodates hose routing while maintaining secure cartridge attachment, thereby reducing overall assembly complexity.
2Strength
If hoses are routed through a metallic sanitary fitting, then the structural integrity is maintained, but direct contact between water and metallic surfaces causes contamination
Solution Approach 1:
The connecting piece serves as an intermediary barrier between the metallic fitting body and the water-carrying hoses. It provides sealed connection points that prevent direct contact between water and metallic surfaces, thereby eliminating contamination risks while maintaining the structural integrity of the metallic fitting.
3Stability of the object's composition
If a fixed connecting piece is used, then the assembly is stable, but the hose routing flexibility is reduced
Solution Approach 1:
The connecting piece incorporates a pivoting mechanism that allows it to rotate relative to the base plate. This dynamic capability enables the connecting piece to adapt to different hose routing requirements while maintaining a stable and secure connection to the cartridge, thus providing both stability and flexibility.
4Manufacturing precision
If custom adapter pieces are manufactured for each cartridge type, then the connection precision is improved, but the manufacturing cost increases
Solution Approach 1:
The connecting piece is designed as a universal component that can accommodate multiple cartridge types through its standardized mounting interface and pivoting mechanism. This multi-functionality eliminates the need to manufacture custom adapter pieces for each cartridge type, thereby reducing manufacturing costs while maintaining adequate connection precision through its adaptable design.
