Integrated Soap-Dispensing Faucet Assembly With Pumped Nozzle Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing faucet assemblies lack an integrated solution for efficiently dispensing liquid soap and detergent while providing a convenient water-spraying mechanism, often requiring manual mixing and separate dispensing systems.
Innovation Solution
A faucet assembly with a housing containing a power module, reservoir, and pump, where the pump is fluidically coupled to the reservoir and nozzle, allowing for automatic dispensing of liquid soap and detergent through a tube extending from the nozzle, controlled by a depressible button.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate dispensing systems are used for water and soap, then each function can be independently optimized, but the device complexity increases and requires manual mixing
Solution Approach 1:
The patent combines the water spraying function and soap dispensing function into a single integrated faucet assembly. The housing contains both the water valve mechanism and the soap reservoir with pump, allowing both functions to be controlled from a single unit rather than requiring separate systems.
Solution Approach 2:
The faucet assembly is designed to perform multiple functions: it can spray water directly, dispense liquid soap, and potentially mix both functions. The single device serves as both a water faucet and a soap dispenser, eliminating the need for separate manual operations.
2Productivity
If manual mixing of water and soap is required, then device complexity is reduced, but productivity and convenience are decreased
Solution Approach 1:
The system performs automatic soap dispensing through an electric pump that is activated by a button press. The pump automatically draws soap from the reservoir and delivers it through the tube to the nozzle, eliminating the need for manual mixing operations by the user.
Solution Approach 2:
The manual mechanical mixing action is replaced with an electric pump system. The pump uses electrical power from the power module to mechanically drive the soap through the tube and out through the nozzle, substituting user manual effort with an automated electromechanical system.
3Extent of automation
If integrated pump and reservoir system is added to faucet, then soap dispensing automation is achieved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The faucet assembly is divided into distinct functional modules: the housing, the power module, the reservoir, the pump, and the tube system. This segmentation allows each component to be manufactured and tested separately before final assembly, simplifying the manufacturing process despite the increased overall system complexity.
Solution Approach 2:
The pump and reservoir are positioned within the housing, with the tube extending through the faucet structure. This nested arrangement consolidates multiple components into a compact integrated unit, reducing the overall space required and simplifying assembly compared to completely separate systems.
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
Enables convenient and efficient dispensing of soap and detergent directly from the faucet, integrating water spraying and soap dispensing functions, enhancing user experience and hygiene.
Implementation Method 1
The pump is operationally coupled to the power module and is fluidically coupled to the reservoir. The pump is configured to motivate the fluids from the reservoir through the tube to be dispensed from the opening in the nozzle.
Implementation Method 2
A nozzle, which is configured to spray water, is fluidically coupled to the faucet.
