Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water outflow devices, such as kitchen faucets and showers, experience poor user experience due to water splashing caused by high pressure, with previous anti-splash solutions like the annular water curtain structure failing to effectively prevent splashing.
Innovation Solution
An anti-splash water outflow device featuring a rotatable inner body with spiral blades that creates a spiral water passage, allowing water to flow spirally downward and out as an annular spray, which continues to rotate and covers any splashing water, providing a larger, continuous, and non-splashing annular water spray.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If water flows out at high pressure, then water outflow strength is improved, but water splashing occurs
Solution Approach 1:
The inner body is designed to rotate dynamically in response to water flow pressure. As water flows through the spiral water passage, it drives the inner body to rotate, which in turn adjusts the water flow pattern dynamically. This dynamic adjustment transforms the direct high-pressure jet into a controlled spiral flow that exits as an annular spray, maintaining outflow strength while preventing splashing.
Solution Approach 2:
The spiral water passage acts as an intermediary element between the water inlet and the water outlet. It transforms the incoming water flow into a spiral motion pattern, and the rotating inner body further modifies this flow. This intermediary mechanism converts the harmful high-pressure direct jet into a beneficial controlled annular spray, eliminating splashing while preserving water delivery strength.
2Shape
If annular water curtain structure is used, then water outflow is shaped, but anti-splash effect is insufficient
Solution Approach 1:
The patent enhances the static annular water curtain structure by adding a rotating inner body that responds to water flow pressure. This dynamic element continuously adjusts the water flow characteristics, creating a more effective anti-splash barrier. The rotation generates centrifugal forces that strengthen the annular spray pattern, making it more effective at preventing splashing compared to fixed annular structures.
Solution Approach 2:
The invention utilizes hydraulic principles by allowing water flow pressure to directly drive the rotation of the inner body. The spiral water passage creates rotational flow patterns that leverage hydraulic forces to generate the desired water spray morphology. This hydraulic-driven mechanism enhances the annular water curtain's effectiveness in preventing splashing.
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
The device effectively prevents water splashing by creating a larger annular water spray that covers strong water flows, ensuring a beautiful, moderate, and splash-free experience, while maintaining the water outflow's strength and continuity.
Implementation Method 1
The water flows into the water outflow body from the water inlet to impact the inner body to drive the inner body to rotate relative to the water outflow body
Implementation Method 2
the water flows through the spiral water passage, flows out of the outlet of the spiral water passage, flows spirally downward along an inner wall surface of the water outflow body, and sprays out of the water outlet to obtain an annular water spray

AI summary
The present disclosure discloses an anti-splash water outflow device comprises a water outflow body and an internal assembly. The internal assembly comprises an inner body that is rotatable relative to the water outflow body upon being impacted by water. The inner body is disposed with at least two spiral blades, and two adjacent spiral blades of the at least two spiral blades define a spiral water passage. The water flows into the water outflow body from the water inlet to impact the inner body to drive the inner body to rotate relative to the water outflow body, and the water flows through the spiral water passage, flows out of the outlet of the spiral water passage, flows spirally downward along an inner wall surface of the water outflow body, and sprays out of the water outlet to obtain an annular water spray shaped as a lampshade.
