Shower Apparatus Uniform Bubble Diameter Aeration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shower apparatuses fail to provide a voluminous feel akin to being showered by large drops of rain, as they produce nonuniform water droplets due to varying bubble diameters in bubbly water, making it difficult to maintain uniform bubble sizes and stable bubbly water supply through all nozzle holes.
Innovation Solution
A shower apparatus design featuring a water supply unit, a throttle unit with a flat-shaped throttle channel to eject a sheet-like stream of water, an aeration unit with an air-liquid interface to produce bubbly water with uniform bubble diameters, and a nozzle unit with nozzle holes aligned along the ejection direction, ensuring uniform bubble flow and stable bubbly water supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If bubbly water is produced by aerating water using an ejector effect and distributed to multiple nozzle holes, then water can be sprayed, but the bubble diameters become nonuniform and bubble enlargement occurs, resulting in nonuniform water droplet sizes
Solution Approach 1:
The invention divides the water supply into multiple separate water supply units, each independently supplying water to its own throttle unit and aeration unit. This segmentation prevents bubble coalescence that would occur in a single mixed flow, maintaining uniform bubble diameters across all nozzle holes while ensuring stable bubbly water supply to multiple nozzles simultaneously
Solution Approach 2:
The invention performs aeration individually for each water stream before the bubbles have a chance to coalesce. By introducing air and creating bubbles separately in each aeration unit before distribution to nozzle holes, the system establishes uniform bubble sizes in advance, preventing the nonuniformity that would develop if aerating water as a single mixed flow
2Ease of operation
If bubbly water changes direction by hitting threaded members and inner walls, then water can be distributed, but bubble diameters become nonuniform due to bubble collisions
Solution Approach 1:
The invention extracts the aeration process from the common water flow path and places it in separate branches for each water supply unit. This removes the source of bubble nonuniformity (bubble collisions in mixed flow) from the distribution system, allowing water to be distributed while maintaining uniform bubble diameters throughout
Solution Approach 2:
By segmenting the water supply into independent units with separate aeration, the invention eliminates the need for bubbly water to change direction through threaded members and inner walls. Each unit maintains its own bubble structure independently, preventing bubble collisions that would occur in a single mixed flow undergoing directional changes
3Device complexity
If a single water supply unit supplies water to multiple nozzle holes, then the structure is simple, but stable bubbly water supply through all nozzle holes cannot be maintained
Solution Approach 1:
The invention divides the single water supply system into multiple independent water supply units, each with its own throttle and aeration components. This segmentation ensures that each nozzle hole receives stable bubbly water independently, preventing the supply instability that would occur in a single mixed flow system while maintaining manageable structural complexity through modular design
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
The apparatus achieves a continuous, voluminous shower experience by maintaining uniform bubble diameters and preventing bubble enlargement, allowing finely divided water droplets of large size to land uniformly, providing a shower feel similar to being showered by large raindrops.
Implementation Method 1
a shower apparatus is known which discharges bubbly water by aerating water using a so-called ejector effect
Implementation Method 2
an aeration unit installed downstream of the throttle unit and provided with an opening adapted to produce bubbly water by aerating the water ejected through the throttle unit

AI summary
Provided is a shower apparatus which can stably supply bubbly water through all nozzle holes and can cause water droplets of large, uniform size to land continuously on the user so as to allow the user to enjoy a shower with a voluminous feel as if the user were being showered by large drops of rain. The shower apparatus includes a water supply unit, a throttle unit adapted to eject passing water downstream, an aeration unit adapted to produce bubbly water by aerating the water ejected through the throttle unit, and a nozzle unit provided with a plurality of nozzle holes used to discharge the bubbly water, wherein the throttle unit has a flat-shaped throttle channel and water ejected through the throttle channel plunges into an air-liquid interface as a sheet-like stream, thereby producing bubbly water, which is then discharged through the nozzle hole.
