Multi-function Sprayhead Valve with Movable Diverters for Three Spray Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional faucet sprayheads typically offer only two functions, limiting the ability to distribute water efficiently to multiple functional outlets, whereas there is a need for a valve that can provide three or more spray functions to enhance water usage efficiency.
Innovation Solution
A fluid control valve with multiple sections defining channels and diverters that are movable to selectively control fluid flow between different chambers, allowing for three distinct spray functions by connecting the inlet to different outlet members, each providing a unique spray mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional sprayhead uses a single valve with two positions, then the device complexity is low, but the sprayhead can only provide two functions (aerated and non-aerated water streams)
Solution Approach 1:
The valve is divided into multiple sections (first section, second section, third section) that define separate channels (first channel, second channel, third channel). Each section can be independently controlled by its own diverter, allowing the valve to direct fluid to multiple different outlets (first outlet member, second outlet member, third outlet member) with different nozzle configurations, thereby providing three or more distinct spray functions.
Solution Approach 2:
The valve incorporates multiple diverters (first diverter, second diverter) that are movable between different positions. The first diverter controls flow between the first and second channels, while the second diverter controls flow between the second and third channels. This dynamic configuration allows the single valve to adaptively provide multiple spray functions by selectively connecting the inlet to different outlet members based on the positions of the diverters.
2Productivity
If a sprayhead provides multiple spray functions through multiple outlets, then water distribution efficiency is improved, but the device complexity increases due to multiple diverters and channels
Solution Approach 1:
The patent combines multiple channels (first channel, second channel, third channel) and multiple outlet members (first outlet member, second outlet member, third outlet member) into a single integrated valve assembly. The first diverter and second diverter work together within the same valve body to control flow distribution to multiple outlets, allowing the system to provide multiple spray functions while maintaining a unified compact structure rather than separate independent systems.
Solution Approach 2:
The valve assembly is designed as a multi-functional component that can direct fluid to multiple different outlets with different nozzle configurations. The same valve body and inlet serve multiple purposes by controlling flow to the first outlet member (with first nozzle configuration), second outlet member (with second nozzle configuration), and third outlet member (with third nozzle configuration), allowing one valve assembly to perform the functions of what would traditionally require multiple separate valves.

AI summary
A fluid control valve includes a first portion, a second portion, and a third portion, which, when combined, define a first channel, a second channel, a third channel, and a fourth channel. Each of the channels is defined by a combination of at least two of the portions. The fluid control valve further includes a first diverter and a second diverter. The first diverter and the second diverter are each movable between a first position and a second position to selectively control a flow of fluid through at least one of the chambers.
