Solution Overview
Problem
There is a need to reduce water consumption and improve water quality, especially in areas where the available water is contaminated, as existing technologies do not effectively address these issues simultaneously.
Innovation Solution
A nozzle that is attachable to a faucet or shower, switchable between mist and spray modes, featuring a housing with a vortex screw and dual filtration, which reduces water flow significantly while effectively purifying water through flash evaporation and filtration, using a combination of filters and a vortex mechanism to create a conical or tubular mist with minimal water consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a conventional faucet is used, then water flow is maintained at normal levels, but water consumption is high and water quality is not improved
Solution Approach 1:
The patent utilizes phase transition by creating mist through rapid evaporation of water droplets. The nozzle generates a vortex that atomizes water into fine droplets that quickly evaporate, forming a mist that can be used for drinking or cooking. This phase transition from liquid to vapor allows minimal water consumption while maintaining useful output.
Solution Approach 2:
The nozzle changes the physical parameters of water by creating a vortex flow that transforms normal water flow into atomized droplets. By adjusting the vortex intensity and droplet size parameters, the system achieves mist generation with 90-99% water savings compared to conventional faucets.
2Quantity of substance
If water is filtered to improve quality, then water purity increases, but device complexity increases
Solution Approach 1:
The nozzle employs self-cleaning functionality where the high-velocity water flow automatically flushes debris and contaminants from the filtration elements. This self-service mechanism maintains filter effectiveness without requiring manual intervention or complex backflushing systems, thereby improving water quality while keeping the device relatively simple.
Solution Approach 2:
The patent extracts only the essential filtration function from complex filtration systems. By using a simple screen or mesh filter combined with the vortex-generated mist, the system removes contaminants sufficient for drinking and cooking purposes without incorporating multiple filtration stages or complex mechanisms.
3Quantity of substance
If a mist mode is implemented to reduce water consumption, then water savings increase, but water flow output decreases
Solution Approach 1:
The system exploits the phase transition from liquid water to vapor mist to resolve the contradiction. By converting water into fine droplets that rapidly evaporate, the nozzle provides a mist output that is sufficient for drinking and cooking applications while consuming 90-99% less water than conventional faucets. The phase transition effectively amplifies the utility of minimal water input.
Solution Approach 2:
The nozzle transforms the parameters of water output by changing from high-volume liquid flow to low-volume aerosol mist. This parameter change allows the system to maintain adequate output for culinary uses while dramatically reducing water consumption, as the mist form is more efficient for drinking and cooking applications.
4Quantity of substance
If dual filtration is implemented to purify contaminated water, then water quality improves, but manufacturing complexity increases
Solution Approach 1:
The patent extracts only the critical filtration elements needed to handle contaminated water for drinking and cooking. By using a simple screen filter combined with the vortex mist generation, the system achieves sufficient purification without incorporating complex multi-stage filtration systems, making the nozzle easier to manufacture while still improving water quality from contaminated sources.
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 nozzle achieves a substantial reduction in water consumption, down to 1% in mist mode and 10% in spray mode of normal faucet flow, while effectively purifying water, making it suitable for drinking and other uses, even with contaminated sources, and is simple, robust, and easy to maintain.

AI summary
The method is for discharging water through a faucet. A nozzle is attachable to a faucet. The nozzle is switchable between a spray- mode and a mist-mode and has a housing with an inner cavity. The inner cavity having filters and a water rotating device disposed therein. The housing has an opening defined therein in fluid communication with the inner cavity and grooves and an orifice at a bottom portion thereof. The second filter is disposed below the opening. The nozzle is attached onto the faucet and switches to the spray- mode. Water flows into the inner cavity and through the first filter. When in the spray-mode, water flows out through the opening and through grooves and is discharged as spray and mist at a bottom of nozzle. When switched to the mist mode, water only flow through the second filter but not through the opening.
