Tub Massage Jets With Sequencer Manifold For Intermittent Air Injection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air and water massage systems in tubs do not provide sufficient variety in massaging effects, despite combining air and water injection, limiting the types of treatments that can be offered.
Innovation Solution
A gas and liquid massage system with a plurality of jets equipped with both gas and liquid injectors, a sequencer manifold to control gas supply intermittently, and a controller to manage the operation of the sequencer manifold, allowing for concurrent injection of liquid and gas into the tub, creating a dynamic massaging experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If air and water are injected simultaneously through jets, then a massaging effect is provided, but the variety of massaging effects is limited
Solution Approach 1:
The system employs periodic action by using a sequencer manifold to intermittently close gas supply to different jets in a sequential manner. This creates varying massage patterns (such as wave patterns, pulsing effects, and alternating sequences) while maintaining a relatively simple system architecture. The controller manages the sequencer to produce different massage effects by controlling the timing and sequence of gas injection to different jet groups.
2Adaptability or versatility
If a simple jet system is used, then the device complexity is low, but the range of treatments is limited
Solution Approach 1:
The system applies segmentation by dividing the jet array into multiple groups that can be independently controlled. The sequencer manifold selectively closes gas supply to different groups of jets in sequence, allowing various treatment patterns to be created by activating different segments. This segmentation enables a wide range of treatments without requiring complex individual control of each jet.
Solution Approach 2:
The system achieves universality through a multi-functional sequencer manifold that can produce multiple massage effects (wave patterns, pulsing, alternating sequences, simultaneous injection) using a single integrated device. The controller manages the sequencer to provide various treatment modes, making the system versatile without requiring multiple separate systems for different treatments.

Function Achieved in This Case
The system enhances the massaging experience by intermittently injecting air through fluid jets, increasing the sensation and dimension of massage, allowing for customizable patterns and modes of operation, thereby providing a more comprehensive treatment.
Implementation Method 1
supplying pressurized liquid to the liquid injector of each jet
Implementation Method 2
supplying pressurized gas to the gas injector of only a portion of the jets
Implementation Method 3
water jets equipped with venturi devices whereby air is sucked by the flow of water directed to the tub

AI summary
A gas and liquid massage system for a tub comprises jets. Each jet has a gas injector and a liquid injector. The jets concurrently inject liquid and gas. A liquid circuit feeds a flow of liquid to the liquid injectors. A gas circuit feeds a flow of gas to the gas injectors. A sequencer manifold in the gas circuit selectively closes the gas supply to some of the jets to intermittently inject gas with the injected liquid. A massage system controller operates the sequencer manifold in selectively closing the gas supply to some of the jets. A method for injecting fluids into the liquid of the tub is also provided.
