Spa Jet Lateral Outlet Adjustment With Constant Outlet Depth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spa jets lack the ability to be selectively adjustable along their width, limiting the user's control over the direction and intensity of water therapy effects.
Innovation Solution
A spa jet assembly with a housing featuring a proximal outlet that is laterally adjustable along the width of the housing, connected by a telescoping tube system with rotatable joints, allowing for angular adjustments of up to 90° while maintaining a constant depth, and optionally a selectively sealable channel for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed spa jet design is used, then the structure is simple and easy to manufacture, but the user cannot adjust the direction and position of water flow for personalized therapy
Solution Approach 1:
The patent applies the dynamics principle by making the proximal outlet movable along a channel within the housing, allowing it to be repositioned from a first position to a second position. This dynamic adjustment capability enables users to change water flow direction while maintaining structural simplicity through a guided movement path rather than complex mechanical linkages.
Solution Approach 2:
The patent segments the outlet structure from the main housing by creating a movable proximal outlet that can be independently repositioned along a channel. This segmentation allows the outlet to be adjusted without moving the entire housing, providing adaptability while keeping the overall device structure relatively simple.
2Ease of operation
If the proximal outlet is made movable along the width, then user control over water therapy direction is improved, but the sealing and positioning precision becomes more difficult to maintain
Solution Approach 1:
The patent introduces a channel as an intermediary structure that guides the movement of the proximal outlet. This channel serves as a mediator between the movable outlet and the housing, providing a predefined path that ensures precise positioning while maintaining effective sealing through the structured interface between the outlet and channel walls.
Solution Approach 2:
The patent replaces complex mechanical sealing systems with a simpler channel-based guidance system. The channel structure provides both positioning guidance and sealing functionality through its geometry, eliminating the need for additional complex mechanical sealing components while maintaining precision.
3Adaptability or versatility
If a telescoping tube system with rotatable joints is used, then the angular adjustment range is increased, but the device complexity and potential leakage points are increased
Solution Approach 1:
The patent applies dynamics by incorporating rotatable joints in the tube system, allowing the tubes to rotate and accommodate angular adjustments up to 90 degrees. This dynamic capability enables wide angular adjustment while maintaining connection integrity through the rotatable joint design that preserves sealing during movement.
Solution Approach 2:
The patent changes the angular parameter of the tube connections through rotatable joints, allowing the system to adapt to different angles while maintaining reliable connections. The ability to rotate the tubes changes the spatial orientation parameter without compromising the sealing integrity of the fluid pathway.

AI summary
This disclosure relates generally to jets for spas and, more specifically, to jets that can be adjusted laterally along a width of the proximal end of the jet housing. The angular adjustment of the proximal outlet of the jet may be at least 30°. In some embodiments, the jet assembly includes a housing with a distal inlet at a distal end of the housing and a proximal outlet at a proximal end of the housing, the proximal outlet laterally adjustable along a width of the proximal end of the housing, with the proximal outlet maintaining a constant depth with respect to the proximal end of the housing as the proximal outlet is laterally adjusted along the width of the proximal end of the housing.
