Faucet Aerator with Center Stream for High-Impact Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Faucets with outlet aerators often deliver water at reduced flow rates, which results in a low-impact water stream that is not suitable for tasks requiring enhanced water force, such as cleaning a razor or toothbrush.
Innovation Solution
A faucet aerator design that includes a housing with a faceplate and a nozzle, discharging a first aerated water stream and a second laminar water stream with greater flow velocity, positioned radially inward of the first stream, providing enhanced force and impact at lower flow rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If reduced flow rates are used in faucets with outlet aerators, then water conservation is improved, but water impact force is reduced
Solution Approach 1:
The aerator divides the water flow into two distinct streams: a peripheral aerated stream and a central laminar stream. This segmentation allows each stream to serve different functions - the aerated stream provides soft water for general cleaning while the central laminar stream delivers concentrated high-impact force for tasks requiring enhanced water force, such as cleaning razors or toothbrushes.
Solution Approach 2:
Different regions of the water stream are given different properties: the peripheral region contains aerated water with lower velocity for gentle cleaning, while the central region contains laminar water with higher velocity for high-impact tasks. This local differentiation of flow characteristics allows the single aerator to simultaneously satisfy both water conservation and enhanced impact force requirements.
2Ease of operation
If aerated water stream is discharged, then water softness and gentle cleaning are improved, but water impact force is reduced
Solution Approach 1:
The aerator separates the water flow into two distinct streams: a peripheral aerated stream providing softness for gentle cleaning, and a central laminar stream providing concentrated impact force. This segmentation resolves the contradiction by allowing both gentle cleaning and high impact force to coexist in the same water delivery system.
Solution Approach 2:
The aerator creates local quality differences within the water stream: the peripheral region has aerated, softer water for gentle cleaning, while the central region has laminar, higher-velocity water for impact force. This spatial differentiation of flow properties enables the system to simultaneously provide both gentle cleaning and enhanced impact force where needed.
3Loss of substance
If single stream aerated water is discharged, then water conservation is maintained, but cleaning effectiveness for certain tasks is reduced
Solution Approach 1:
The aerator divides the water flow into two functional streams: a peripheral aerated stream for general cleaning and a central laminar stream for tasks requiring enhanced force. This segmentation improves cleaning effectiveness for specific tasks (like cleaning razors or toothbrushes) while maintaining overall water conservation through the aerated stream.
Solution Approach 2:
The aerator design provides multi-functionality by delivering both a soft aerated stream for general cleaning tasks and a high-impact laminar stream for specialized tasks requiring enhanced force. This universal design allows the single aerator to handle diverse cleaning needs effectively while maintaining water conservation.

Function Achieved in This Case
The faucet aerator effectively delivers water with enhanced force and impact at lower flow rates, improving efficiency for tasks like cleaning while maintaining water conservation goals, with the laminar stream providing greater cleaning effectiveness and the aerated stream preventing splashing.
Implementation Method 1
the first water stream is an aerated stream of water
Implementation Method 2
the second water stream is a substantially laminar stream of water
