Pull-Out Faucet Cartridge Layout With Hose-Through Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 'pull-out' fittings in sanitary facilities face challenges in achieving a compact design due to the installation space required for the hose, which makes it difficult to accommodate a mixing valve directly within the fitting housing.
Innovation Solution
A fitting design featuring a housing with a mixing cartridge and a hose that extends through a channel within the cartridge, allowing the mixing cartridge to be arranged within the housing, enabling a space-saving configuration while maintaining fluid flow and temperature control through inlet and outlet connections and an actuating unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the hose is arranged within the fitting housing, then the fitting achieves a compact design, but the installation space required for the hose makes it difficult to accommodate a mixing valve directly in the fitting
Solution Approach 1:
The hose is routed through a channel formed within the mixing cartridge itself, nesting the hose passage inside the mixing valve body. This allows the mixing valve to be compactly arranged within the fitting housing while the hose extends through the cartridge's internal channel to reach the spout, resolving the space conflict between compact housing and valve accommodation.
2Device complexity
If the mixing valve is arranged at a distance from the housing, then the hose passage is simplified, but the fitting design becomes less compact
Solution Approach 1:
The mixing cartridge integrates multiple functions into a single component: it houses the mixing valve, provides the hose channel, and connects to the spout. By merging the valve body, hose passage, and connection elements into one integrated cartridge, the design achieves compact housing arrangement while maintaining simplified hose routing through the unified structure.
