Sprayhead Diverter Valve Layout for Three Spray Functions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional faucet sprayheads typically offer only two functions, limiting their ability to efficiently distribute water to multiple outlets and provide specialized spray patterns for various tasks.
Innovation Solution
A fluid control valve with multiple chambers and diverters allows for the distribution of water to multiple outlets, enabling three or more distinct spray functions by controlling fluid flow between different chambers and outlets through movable diverters and actuators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional sprayheads with two functions are used, then the device complexity is low, but the adaptability or versatility is limited
Solution Approach 1:
The valve body is divided into multiple chambers (first chamber, second chamber, third chamber) that are selectively fluidly connected through movable diverters. This segmentation allows independent control of different spray functions while maintaining a compact integrated structure.
Solution Approach 2:
Movable diverters are introduced to dynamically switch fluid connections between chambers and outlets. The diverters can change position to establish or disconnect fluid pathways, enabling the sprayhead to switch between multiple functions (aerated stream, non-aerated stream, spray pattern) without requiring separate valves for each function.
2Adaptability or versatility
If multiple chambers and diverters are added to provide three or more spray functions, then the adaptability or versatility improves, but the device complexity increases
Solution Approach 1:
The valve body serves multiple functions by incorporating multiple chambers and outlets within a single structure. The same valve body houses the first chamber for aerated stream, second chamber for non-aerated stream, and third chamber for spray pattern, allowing one component to perform multiple spray functions that would traditionally require separate devices.
Solution Approach 2:
Multiple spray functions are merged into a single integrated valve assembly. The first outlet, second outlet, and third outlet are all connected to the same valve body, and the diverters are integrated within the valve structure, combining what would traditionally be separate spray devices into one unified multi-functional unit.
3Adaptability or versatility
If movable diverters are used to control fluid flow between chambers, then the adaptability improves, but the ease of manufacture decreases
Solution Approach 1:
The diverters are positioned within the valve body chambers in a nested arrangement. The first diverter is located within the first chamber, the second diverter within the second chamber, allowing compact integration of moving parts within the valve structure without requiring additional external components or complex assembly procedures.

AI summary
A sprayhead that includes a body and first and second diverters. The body has an inlet for receiving a fluid; first, second, and third chambers; and first, second, and third outlets for dispensing the fluid in first, second, and third modes, respectively. The first diverter moves between a first position wherein the second chamber fluidly connects to the inlet and the first chamber fluidly disconnects from the inlet and a second position wherein the first outlet fluidly connects to the inlet through the first chamber and the second chamber fluidly disconnects from the inlet. The second diverter moves between a first position wherein the second outlet fluidly connects to the second chamber and the third chamber fluidly disconnects from the second chamber and a second position wherein the third outlet fluidly connects to the second chamber through the third chamber and the second outlet fluidly disconnects from the second chamber.
