Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current spraying devices for pools fail to achieve desired spraying effects, lacking in providing a variety of water playing experiences, oxygen enrichment, and water purification, while also being prone to scale formation.
Innovation Solution
A Venturi tube-based spraying device with a first opening, a second opening, and an air vent, where water flow through the tube increases velocity, creating negative pressure to draw in air, forming a high-speed water-air mixture for improved atomization and massage effects, while preventing scale formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional spraying devices are used, then the structure is simple, but the spraying effect is poor and cannot provide varied water playing experiences
Solution Approach 1:
The patent applies the Venturi effect by designing a tube with varying cross-sectional areas (narrow throat portion between wider first and second openings) to create negative pressure that draws air into the water flow. This pneumatic-hydraulic interaction generates the air-water mixture spray without complex mechanical components, achieving varied spraying effects while maintaining relatively simple device structure
Solution Approach 2:
The patent changes the geometric parameters of the tube, specifically creating a throat portion with smaller cross-sectional area than the first and second openings. This parameter change creates the Venturi effect that generates negative pressure, enabling air entrainment and improved spray atomization without adding complex mechanisms
2Adaptability or versatility
If water flow velocity is increased to improve spray atomization, then spraying effect improves, but scale formation in the tube increases
Solution Approach 1:
The high-velocity water flow through the narrow throat portion creates negative pressure that entrains air into the flow. The resulting air-water mixture reduces the direct contact time of water with tube walls and disrupts scale-forming deposits, allowing high velocity operation without excessive scale accumulation while maintaining good atomization
3Quantity of substance
If conventional spraying devices are used, then the device structure is simple, but oxygen content of pool water is insufficient
Solution Approach 1:
The Venturi tube design creates negative pressure in the throat portion that actively draws air into the water flow. The resulting air-water mixture increases oxygen content as the air bubbles dissolve into the pool water during circulation, achieving oxygen enrichment without complex aeration equipment
Solution Approach 2:
The same Venturi tube structure simultaneously achieves multiple functions: improved spray atomization for water playing, oxygen enrichment through air entrainment, and water purification through increased circulation. This multi-functionality achieves oxygen enrichment without adding separate aeration devices
4Adaptability or versatility
If conventional spraying devices are used, then the device structure is simple, but water purification and circulation effect is weak
Solution Approach 1:
The Venturi tube structure simultaneously provides spray function and water purification through its air-water mixing capability. The high-velocity flow and air entrainment enhance oxygen transfer and promote water circulation, achieving purification effects without separate aeration or filtration components
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 enhances water playing experience, increases oxygen content, improves water purity, and reduces scale formation by producing a high-speed water mist or air-water mixture with better atomization and filtration circulation.
Implementation Method 1
The Venturi tube has a throat portion arranged between the first opening and the second opening, and a tube diameter of the throat portion is less than an opening diameter of the first opening and less than an opening diameter of the second opening. When the water flow flows through the throat portion, it has an increased flow velocity since the tube diameter shrinks. As a result, the water flow forms a negative pressure near the throat portion, so that outside air enters the Venturi tube through the air vent under the negative pressure
Implementation Method 2
the water flow forms a negative pressure near the throat portion, so that outside air enters the Venturi tube through the air vent under the negative pressure, is mixed with the water flow
Implementation Method 3
a water-air mixture is finally sprayed out of the second opening in a shape of a high-speed jet, so as to form water mist with a better atomization effect
