Multifunction Faucet Spray Head with Dynamic Boost Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional kitchen faucets have limited functional spray modes, which restrict their effectiveness in cleaning tasks, especially with reduced water flow rates, making them inefficient for filling pots and cleaning surfaces.
Innovation Solution
A multifunctional kitchen faucet spray head with a rotatable face plate providing multiple spray functions, including aerated, shower, misting, and jet sprays, along with a pause and boost feature to enhance flow rate, is designed to address these limitations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If water saving code requirements are enforced to reduce flow rate, then water consumption is reduced, but the time to fill pots increases and cleaning effectiveness decreases
Solution Approach 1:
The spray head incorporates a boost button that dynamically changes the flow rate from a restricted state to an enhanced state. When the boost button is pressed, it opens a restricted flow passage to allow increased water flow, enabling fast filling of pots and pans while maintaining water-saving operation during normal use. This dynamic adjustment resolves the contradiction between water conservation and filling speed.
2Loss of substance
If flow rate is reduced for water saving, then water consumption is reduced, but cleaning effectiveness of dishes and sink decreases
Solution Approach 1:
The boost button provides dynamic flow rate adjustment, allowing users to switch between water-saving mode and high-flow cleaning mode. When cleaning dishes or sink surfaces, pressing the boost button increases water flow to restore cleaning effectiveness while maintaining overall water conservation during other operations.
Solution Approach 2:
The system changes the flow rate parameter from a restricted value to an enhanced value when the boost button is activated. This parameter change allows the same spray head to serve dual purposes: water-saving operation during normal use and high-flow operation during cleaning tasks, resolving the contradiction between water consumption and cleaning effectiveness.
3Device complexity
If conventional spray head design is used, then device complexity is low, but functionality and versatility are limited
Solution Approach 1:
The spray head is designed with multiple functions including normal spray mode, boost mode for fast filling, and various spray patterns. The rotatable face plate allows selection between different spray functions, making the device versatile for multiple kitchen tasks while maintaining a relatively simple overall structure that integrates these functions into a single unit.

AI summary
A faucet assembly with a multifunction spray head is provided. The spray head is capable of four spray functions, and has an outer shell; a flow body extending within the shell, a first end extending out of the shell for attachment to a faucet and a second end in fluid communication with a spray selector assembly. The flow body defines a flow path from the first end of the flow body to a flow selector assembly. The spray head includes a flow selector assembly comprising: a selector valve housing body having at least four valve recesses therein; at least four flow selector valves seated within the recesses in the selector valve housing body; and a rotating selector valve ring. A sprayer seat has a faceplate and a flow diversion conduit corresponding to each selector valve to provide flow paths from a selector valve to a sprayer outlet or aerator outlet.
