Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shower heads for generating microbubbles are complex in structure, requiring a flow swirling path and liquid swirling blade, which complicates the manufacturing process and increases costs.
Innovation Solution
A shower head design featuring a gas-liquid mixing portion at the upstream side of the introducing path, a spray plate with multiple apertures, and a discharge path that includes a compression and decompression section to absorb gas and reduce pressure, minimizing bubble merger and promoting microbubble generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a flow swirling path and liquid swirling blade are provided to generate microbubbles, then microbubble generation is improved, but device complexity increases
Solution Approach 1:
The invention extracts the essential function of microbubble generation from the complex swirling flow system. By removing the flow swirling path and liquid swirling blade, it retains only the critical pressure reduction mechanism through the enlarged path and discharge path configuration, achieving microbubble generation without the unnecessary complex components.
Solution Approach 2:
The invention uses hydraulic principles to generate microbubbles. The enlarged path and discharge path are designed to create pressure reduction zones where water pressure naturally drops, causing dissolved gases to form microbubbles. This hydraulic approach replaces the mechanical swirling blade system with a simpler pressure-based bubble generation mechanism.

Solution Approach 2:
The invention replaces expensive, complex mechanical components (swirling blade, flow swirling path) with simpler, cheaper structural features (enlarged path geometry, discharge path configuration). This simplification reduces manufacturing costs while maintaining the microbubble generation function through pressure reduction alone.
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 design achieves a simple structure for microbubble generation, suppressing bubble merger and enhancing the washing function by producing a high volume of microbubbles with large specific surface areas, while reducing manufacturing complexity and costs.
Implementation Method 1
a gas absorbed by pressure reduction during introducing the warm or cold water in the warm or cold water
Implementation Method 2
the warm or cold water introduced in the second introducing path of the gas-liquid mixing portion is once pressurized when passing the compression portion
Implementation Method 3
the pressure of the warm or cold water is subsequently reduced when passing the decompression portion
Implementation Method 4
each of cross-sections in a length direction of the enlarged path of the introducing path has a cross-sectional area so that a volume of the warm or cold water passing per unit time is similar to one another

AI summary
In a shower head including a head main body provided with a gas-liquid mixing portion, a spray plate having a plurality of spray apertures, and a discharge path formed between the head main body and the spray plate, an introducing path has an enlarged path at a side of an exit of the introducing path and a discharge path is disposed perpendicular to a side of an exit of the introducing path and an entrance of the discharge path has a cross-sectional area at which a volume of the warm or cold water flowing into the discharge path per unit time is equal to or less than a volume of the warm or cold water passing a portion except the enlarged path of the introducing path per unit time.
