Low Profile Spa Jet Assembly with Interchangeable Face
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spa jets require recessed pockets for installation, limiting configuration options and protruding further from the spa wall, which affects comfort and manufacturing complexity during 'dry tests' and installation.
Innovation Solution
A low-profile spa jet design that protrudes less than 0.5 inches into the spa tub, allowing interchangeable jet faces/flanges for both grommet and nut installations, enabling flexible configuration and reduced protrusion, with adjustable orientations and integrated accent lighting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional spa jets are designed with recessed pockets for installation, then the jets can be securely mounted, but the jets protrude further from the spa wall which affects bather comfort and limits configuration options
Solution Approach 1:
The jet assembly is divided into separate components: a jet body, an interchangeable jet face/flange assembly, and a mounting mechanism. This segmentation allows the jet face to be optimized for comfort while the body maintains structural integrity and low protrusion.
Solution Approach 2:
The jet face/flange assembly is made interchangeable and rotatable, allowing dynamic adjustment of orientation and configuration. This enables the same jet body to serve multiple purposes and adapt to different bather needs while maintaining low profile installation.
2Adaptability or versatility
If recessed pockets are used for jet installation, then secure mounting is achieved, but manufacturing complexity increases and configuration options are limited
Solution Approach 1:
The jet body is designed with a universal mounting interface that accepts different jet face/flange assemblies. This single jet body can be configured for multiple functions and installations without requiring different pocket designs, simplifying manufacturing while increasing versatility.
Solution Approach 2:
The rotatable and interchangeable jet face assembly allows the same jet body to be configured in different orientations and applications. This dynamic reconfigurability eliminates the need for multiple specialized jet designs, reducing manufacturing complexity while maintaining high adaptability.
3Ease of operation
If jets protrude further from the spa wall, then installation is simplified, but bather comfort is reduced and clothing may become snagged
Solution Approach 1:
By separating the jet face from the jet body, the design allows the face to be optimized for comfort (low profile) while the body handles the installation mechanics. The interchangeable face assembly can be pre-configured for optimal comfort and then attached to the low-protrusion body.
Solution Approach 2:
The interchangeable jet face/flange assembly acts as an intermediary between the low-protrusion jet body and the water flow requirements. It mediates between the conflicting needs of low profile installation and functional performance, allowing both to be achieved simultaneously.
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
Enables multiple spa configurations from a single molded shell, enhances bather comfort during dry tests, simplifies installation, and provides unique lighting effects.
Implementation Method 1
As the water flows through the nozzle, air is drawn from an inlet into a low pressure area and mixes with the water

AI summary
A low profile spa jet having a structure allowing for the use of a jet housing for both threaded/nut and grommet installation, wherein the jet protrudes into the spa tub less than 0.5″. The low profile spa jet also can have a jet face/flange that is interchangeable between threaded and grommet jet bodies without changing the relationship to the spa wall, wherein the jet protrudes the same amount in the installed state for both styles of jet body. The low profile spa jet also can have a jet face/flange that is removable and/or interchangeable before and after the jet body and jet internal are installed in the spa.
