Solution Overview

Problem

Current water jet systems in spas and hot tubs are difficult to clean and disinfect, often requiring disassembly and using harsh chemicals, which can lead to bacterial growth and discomfort due to high-pressure, low-volume jet streams.

Innovation Solution

A water jet assembly with a diaphragm and exciter that generates a toroidal soliton wave, allowing for efficient cleaning without disassembly, using a toroidal soliton effect to produce a massaging effect with low pressure and high volume, and incorporating antibacterial materials to prevent bacterial growth.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-generated harmful factors

If traditional high-pressure, low-volume jet streams are used, then massaging effect is achieved, but bacterial growth is promoted and user comfort is reduced

Engineering Contradiction:

Improvebacterial growthVSAvoiduser comfort

Core Design Contradiction:

Object-generated harmful factorsVSEase of operation

Solution Approach 1:

The patent changes the parameters of the jet stream from high-pressure/low-volume to low-pressure/high-volume by using a diaphragm pump mechanism. This parameter change eliminates the harmful effect of bacterial growth while maintaining user comfort through gentler water flow, directly resolving the technical contradiction between preventing bacterial growth and ensuring user comfort.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent replaces traditional high-pressure mechanical jet systems with a diaphragm-based pumping mechanism that generates low-pressure, high-volume flow. This substitution eliminates the conditions that promote bacterial growth while providing a more comfortable massaging effect, addressing both aspects of the contradiction.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If pipes and fittings are used in jet systems, then water delivery is achieved, but cleaning and disinfection become difficult

Engineering Contradiction:

Improvecleaning accessibilityVSAvoidsanitation effectiveness

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent removes the pipes and fittings from the jet system, extracting the problematic elements that make cleaning difficult. The water delivery function is achieved through a direct diaphragm pump mechanism without traditional piping, allowing complete drainage and easy access to all components for thorough cleaning and disinfection, thus resolving the contradiction between cleaning accessibility and sanitation effectiveness.

Inventive Principle:

Principle #2Taking out (Extraction)

3Loss of time

If disassembly is required for cleaning, then thorough cleaning is possible, but time and complexity increase

Engineering Contradiction:

Improvecleaning timeVSAvoidcleaning simplicity

Core Design Contradiction:

Loss of timeVSEase of operation

Solution Approach 1:

The patent designs the jet system with self-service cleaning capabilities, where the diaphragm pump and associated components can be easily accessed and cleaned without disassembly. The system allows users to perform thorough cleaning procedures simply by draining water and applying cleanser, eliminating the need for complex disassembly while ensuring complete cleaning, thus resolving the contradiction between cleaning time and simplicity.

Inventive Principle:

Principle #25Self-service

4Object-generated harmful factors

If chemicals are used to control bacteria, then bacterial growth is inhibited, but water quality maintenance becomes complex and costly

Engineering Contradiction:

Improvebacteria controlVSAvoidwater quality maintenance complexity

Core Design Contradiction:

Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

The patent converts the harmful effect of bacterial growth into a beneficial outcome by designing a system where complete drainage and direct diaphragm pump access allow mechanical removal of bacteria through thorough cleaning. This eliminates the need for chemical treatments, simplifying water quality maintenance while effectively controlling bacteria, thus resolving the contradiction between bacteria control and maintenance complexity.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

A device and method for producing pulsating waves of energy for the massaging effect normally associated with high pressure jet systems in whirlpools, pedicure spas, bathtubs and other medical and non-medical devices. The jet assembly includes no external pipes and unlike “pipeless” jet assembly systems in use today, does not require disassembly or circulation of chemical cleaning agents to maintain a sanitary condition of the jet assembly.
