Bath with micro bubble apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bubble generating apparatuses for micro bubble production are costly and impractical for large-scale use due to inefficiencies in gas release and clogging issues with small orifices, making them unsuitable for integration with fluid dispensing fittings like hydrotherapy jets and shower heads.
Innovation Solution
A system that uses a high-pressure pump to mix gas and liquid in a pressure vessel, creating micro bubbles that remain suspended in water, with a micro bubble jet distributing them into a bath, and a filter to prevent debris clogging, allowing for efficient and practical micro bubble generation in hydrotherapy systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If small orifices and screens are used to generate micro bubbles, then micro bubble generation efficiency is improved, but clogging by debris and contaminants occurs
Solution Approach 1:
The system divides the micro bubble generation function into two separate components: a saturation tank with large openings for gas dissolution, and a discharge nozzle with narrow parts for micro bubble formation. This segmentation allows each component to be optimized independently - the saturation tank avoids clogging by using large openings, while the discharge nozzle efficiently generates micro bubbles through controlled pressure reduction and flow transformation.
Solution Approach 2:
The system performs preliminary gas saturation of the liquid in the saturation tank before the liquid reaches the micro bubble generation zone. By pre-dissolving gas into the liquid under pressure in the saturation tank, the subsequent micro bubble generation at the discharge nozzle becomes more efficient without requiring the liquid to pass through clog-prone small orifices.
2Reliability
If prefiltering is implemented to prevent clogging, then system reliability is improved, but cost and complexity increase
Solution Approach 1:
The system separates the gas dissolution function (in the saturation tank with large openings) from the micro bubble generation function (at the discharge nozzle). This eliminates the need for prefiltering before gas dissolution, as the large openings in the saturation tank are not susceptible to clogging, thereby reducing system complexity and cost while maintaining reliability.
3Productivity
If continuous cleaning of micro bubble producing screens is required, then micro bubble generation efficiency is maintained, but ease of operation deteriorates
Solution Approach 1:
The system separates gas dissolution (in the saturation tank) from micro bubble generation (at the discharge nozzle). The saturation tank uses large openings that do not clog, eliminating the need for continuous cleaning. The discharge nozzle, while having narrow parts, is designed to be externally threaded for easy removal and cleaning, significantly improving ease of operation compared to integrated screens.
Solution Approach 2:
The discharge nozzle is designed with an externally threaded body that allows users to easily remove and clean it themselves without requiring specialized tools or services. This self-service design maintains micro bubble generation efficiency through simple user-maintainable cleaning.
4Duration of action of stationary object
If back pressure is reduced to prevent component wear, then system longevity is improved, but micro bubble generation efficiency decreases
Solution Approach 1:
The system separates gas dissolution (in the saturation tank) from micro bubble generation (at the discharge nozzle). This allows the saturation tank to operate at high pressure for efficient gas dissolution without subjecting the entire system to excessive back pressure. The discharge nozzle then converts this pressurized saturated liquid into micro bubbles through controlled pressure reduction, maintaining efficiency while protecting system components.

AI summary
A micro bubble generating system includes a shell (200) having a well for retaining a first liquid to immerse an object. A micro bubble apparatus (124) is provided to the shell for providing a pressurized mixture of a second liquid and a dissolved gas into the well so as to create a plurality of micro bubbles within the first liquid for engaging the object.
