Faucet End Piece Valve Mechanism for High Velocity Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing faucet systems face inefficiencies in water pressure and velocity, particularly at low water supply pressures, which can hinder tasks like rinsing and fail to conserve water effectively.
Innovation Solution
A faucet end piece with a cylindrical body, hollow vertical pipe, internal partition, and a valve mechanism biased by a resilient element, allowing water to flow through side orifices at low tap openings for high velocity and through passages at higher openings for standard flow, optimizing water use and pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a faucet head screen is used to diffuse water, then water velocity is regulated, but output water pressure is limited and water conservation is poor
Solution Approach 1:
The faucet end piece is divided into multiple functional sections: an inlet section receiving water from the faucet, a hollow vertical pipe for high-velocity flow, an internal partition with water passages for standard flow, and an outlet section. This segmentation allows water to be directed through different paths based on flow conditions, enabling both high-velocity spray and water conservation modes within a single device.
2Stress or pressure
If water pressure is increased to improve rinsing effectiveness, then water velocity increases, but water consumption increases
Solution Approach 1:
Different sections of the faucet end piece provide different flow characteristics: the hollow vertical pipe section provides high-velocity, high-pressure flow for effective rinsing with minimal water, while the internal partition water passages provide standard flow for general use. The valve mechanism locally controls which path water takes, allowing high pressure without proportionally high water consumption when the hollow pipe path is activated.
3Speed
If a valve mechanism is added to control water flow paths, then water velocity and pressure are optimized, but device complexity increases
Solution Approach 1:
The valve mechanism is designed to be self-actuating based on water pressure conditions. When water flows through the faucet, the pressure differential automatically positions the valve to direct water through the appropriate path (hollow vertical pipe for high velocity or internal partition passages for standard flow). This eliminates the need for external actuators, motors, or complex control systems, maintaining simplicity while achieving optimized water flow control.

Implementation Method 1
a resilient element insertable within the cavity of the cylindrical body between the internal partition of the cylindrical body and the flange portion of the valve for biasing the valve upwardly
Implementation Method 2
The valve is movable vertically within the cavity under the effect of the water pressure between an upper position range wherein water is allowed to flow down through the at least one side orifice

AI summary
A faucet end piece connectable to a faucet nozzle is provided including a cylindrical body defining a cavity, a vertical pipe extending within the cavity, and an internal partition with water passages therethrough, extending across the cavity and connecting the vertical pipe to the body; a valve insertable in the cavity including a cap portion fitting over the vertical pipe and having at least one side orifice, a bore and a flange portion projecting transversally from the cap portion; a resilient element insertable inside the cavity between the body's internal partition and the valve flange portion. The valve is movable vertically under water pressure between an upper position wherein water flows through the cap portion side orifice, the bore and through the body vertical pipe, and a lower position where water flows around the cap portion through the internal partition water passages.
