Spa Jet With Tangential Venturi for Pulsating Massage in Tight Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spa jets with axial venturi discharge ports require complex mechanisms with moving parts for spinning massage patterns, occupy significant space, and cannot be installed in spaces like the spa footwell due to their length and need for additional components.
Innovation Solution
A spa jet design with a crosswise and tangential venturi orientation that generates a vortex and pulsating discharge without moving parts, using a jet body with a water spinning chamber and faceplate discharge openings, allowing for shorter jet bodies that can be installed in tighter spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If axial alignment venturi discharge port is used, then discharge flow is perpendicular to jet face, but no spinning massage pattern is created
Solution Approach 1:
The patent replaces the mechanical spinning system (bearings, spindles, spinners) with a hydraulic vortex generation system. The venturi discharge port is oriented crosswise and tangential to the jet body, creating a vortex that generates spinning massage pattern through fluid dynamics rather than mechanical rotation.
Solution Approach 2:
The patent uses hydraulic principles to generate the spinning massage effect. By orienting the venturi discharge port crosswise and tangential to the jet body, the water flow creates a vortex that produces the desired spinning massage pattern without any mechanical moving parts.
2Ease of operation
If axial alignment venturi is used, then discharge flow is perpendicular to jet face, but long jet bodies are required
Solution Approach 1:
The patent changes the orientation of the venturi discharge port from axial alignment to a crosswise and tangential orientation. This dimensional change in the discharge port orientation allows the jet body to be shorter while still achieving the desired discharge flow perpendicular to the jet face.
3Ease of operation
If axial alignment venturi with spinners and bearings is used, then spinning massage pattern is created, but reliability decreases due to wear and tear
Solution Approach 1:
The patent eliminates mechanical moving parts (bearings, spindles, spinners) by using a fixed venturi discharge port oriented crosswise and tangential to the jet body. The spinning massage pattern is generated through hydraulic vortex creation rather than mechanical rotation, thereby eliminating wear and tear and improving reliability.
4Ease of operation
If axial alignment venturi is used, then discharge flow is perpendicular to jet face, but space behind spa wall is insufficient
Solution Approach 1:
The patent changes the venturi discharge port orientation from axial to crosswise and tangential, which allows the jet body to be shorter and fit in spaces with limited depth behind the spa wall while still achieving discharge flow perpendicular to the jet face.
Solution Approach 2:
Instead of orienting the venturi discharge port axially with the jet body (conventional approach), the patent inverts the orientation to be crosswise and tangential. This inverted approach reduces the required jet body length and allows installation in confined spaces.
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
Creates a natural massage feel with hydraulic efficiency, finer air-water mixture, and oxygenated water, while reducing complexity and wear, and enabling installation in restricted spa areas.
Implementation Method 1
a venturi is used for creating a local vacuum, mixing air and water, then discharging the air and water mix into the spa water
Implementation Method 2
discharges water or a mixture of water and air in a crosswise and tangential orientation into said inner circumference of said jet body to generate a vortex
Implementation Method 3
generate a vortex and pulsating discharge from said jet body without the use of any moving or spinning solid parts
Data Source
AI summary
A spa jet body that provides venturi in a crosswise and tangential orientation to the exit port of water/air mixture which provides for the elimination of moving parts inside of the jet body to create turbulence when in a perpendicular orientation and preserves precious space behind a vertical spa wall or a spa foot well. The venturi enters the inner circumference of the jet body turbulence chamber in a tangential and crosswise orientation, creating turbulence therein with the water/air mixture exiting out the massage head in a pulsating manner, the massage head being a face plate with exit apertures, some of them being specially designed for the footwell. The face plate connects to the jet body through a nut which is secured with screws that pass through the face plate onto the open perimeter top of the jet body.
