Faucet System With Segmented Beverage Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing faucet systems for delivering beverages lack user-friendly interfaces, making it difficult for users to select specific beverages among various options.
Innovation Solution
A faucet system with multiple user interfaces, including mechanical and electrical valves and a selection unit, allowing users to choose between different beverage options, such as chilled, hot, and carbonated water, with the ability to mix fluids and add additives, using a control unit to activate valves and pumps based on user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple beverage options are provided through a single faucet spout, then beverage variety is improved, but user selection difficulty increases
Solution Approach 1:
The faucet system is segmented into multiple independent control units, each managing a specific beverage type (sparkling water, hot water, chilled water, flavored water). Each control unit has its own valve and outlet conduit, allowing users to select beverages through distinct, simple controls rather than navigating a complex single-interface system.
Solution Approach 2:
A control unit acts as an intermediary between the user and the multiple beverage sources. The control unit receives user input and automatically activates the appropriate valve and pump combinations to deliver the selected beverage, eliminating the need for users to manually manage multiple selection parameters.
2Adaptability or versatility
If multiple valves and control units are added to improve beverage selection, then beverage variety is improved, but device complexity increases
Solution Approach 1:
Multiple inlet conduits carrying different beverage types (mains water, chilled water, hot water, carbonated water) are merged into a single mixing chamber. The mixing chamber integrates all fluid streams and allows them to be combined in various proportions before delivery, reducing the need for separate outlet conduits for each beverage combination.
Solution Approach 2:
The mixing chamber serves multiple functions: it receives inputs from all beverage sources, mixes them in variable proportions, and delivers the combined output through a single conduit. This multi-functional component reduces overall system complexity by eliminating the need for separate mixing mechanisms for each beverage pair.
3Temperature
If hot and cold mains water are mixed in the faucet, then temperature variety is improved, but bacterial growth risk increases
Solution Approach 1:
Water is pre-heated or pre-chilled in separate tanks before being supplied to the faucet. The heating element heats mains water in a sealed tank, and the cooling element chills water in another sealed tank. This preliminary temperature adjustment occurs in isolated environments, preventing bacterial contamination during the temperature adjustment process.
Solution Approach 2:
The temperature adjustment functions (heating and cooling) are extracted from the faucet body and placed in separate external tanks. This separation removes the potential contamination zone from the faucet interior, as temperature changes occur in isolated tanks rather than in the faucet's fluid pathways where bacteria could thrive.
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
The system provides improved usability and flexibility, enabling users to easily select and customize beverages, ensuring quality and reducing residue impact on the faucet system.
Implementation Method 1
at least one electrically operated pump that is configured to convey liquid via at least a fourth inlet conduit upstream of the pump to a third outlet conduit downstream of the pump
Implementation Method 2
the first valve is configured to selectively at least partially open or close the first inlet conduit and/or the second inlet conduit

AI summary
A faucet system comprises a first user interface connected to a first valve, a first inlet conduit and/or a second inlet conduit, and a first outlet conduit, and a second user interface connected to a second valve, a third inlet conduit, and a second outlet conduit. The second valve is operated by a selection unit that outputs an electrical signal. A third user interface is connected to an electrically operated pump that conveys liquid via a fourth inlet conduit upstream of the pump to a third outlet conduit downstream of the pump. The third user interface comprises an input unit that outputs an electrical signal based on which the pump is operated with respect to the conveying rate and/or the operation time of the pump. Each selection possibility of the input unit is associated to a different electrical signal. A liquid additive is supplied via the fourth inlet conduit.
