Pull-Out Faucet Mixing Cartridge with Through-Hose Compact Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pull-out sanitary fittings face challenges in achieving a compact design due to the installation space required for the hose and the need to position the mixing valve at a distance from the housing, making it difficult to integrate the mixing valve directly within the fitting.
Innovation Solution
A fitting design that incorporates a mixing cartridge with a channel within the housing, allowing the hose to pass through, and an actuation unit that adjusts the fluid temperature and flow rate, enabling the mixing valve to be placed inside the housing while maintaining a compact form factor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the hose is passed through the fitting housing, then the hose can be connected to the outlet, but the installation space is displaced and the mixing valve cannot be accommodated inside the fitting
Solution Approach 1:
The hose is routed through the mixing cartridge itself rather than through the housing, nesting the hose passage within the mixing cartridge structure. This eliminates the need for separate hose passage space in the housing and allows compact integration of all components within the fitting.
2Ease of operation
If the mixing valve is arranged at a distance from the housing, then the hose can be passed through, but the fitting becomes less compact
Solution Approach 1:
The mixing cartridge is integrated directly into the housing structure, merging the mixing valve function with the housing. The hose passage is combined with the mixing cartridge channel, eliminating the need for separate spacing and achieving a compact integrated design.
3Volume of stationary object
If the mixing cartridge is integrated inside the housing with the hose passing through it, then a compact design is achieved, but the hose must be routed through the mixing cartridge channel
Solution Approach 1:
The mixing cartridge channel serves dual functions: it provides the mixing pathway for fluid and simultaneously serves as the hose passage. This multi-functionality eliminates the need for separate hose routing channels and simplifies the overall structure despite the compact integration.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design allows for a more compact and space-efficient pull-out fitting by integrating the mixing cartridge within the housing, allowing for easier hose passage and improved fluid control through the actuation unit, enhancing the fitting's usability and aesthetics.
Implementation Method 1
a mixing cartridge (4) arranged in the housing (2) and having a first feed connection (5), a second feed connection (6), a mixing region (7) for mixing a fluid flowing into the mixing region via the feed connections (5, 6)
Implementation Method 2
an actuation unit (9) for actuating the mixing cartridge (4), wherein a volumetric flow, which flows into the mixing region (7) via the corresponding feed connection (5, 6) and from there into the outlet connection (8), can be adjusted by means of the valves (14, 15)
