Solution Overview

Problem

Existing showerheads require separate apparatuses and installations to generate micro air bubbles, which are cumbersome and inefficient, and do not effectively address skin irritation and cleaning performance without using chemical cleaning agents.

Innovation Solution

A showerhead design that integrates bubble-generating tubes, a fluid regulator part, and a shower part to produce micro air bubbles directly in the shower water, allowing for adjustable flow rates and bubble generation without external apparatuses, enhancing cleaning efficacy and skin benefits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a separate apparatus for generating micro air bubbles is installed, then micro air bubbles can be generated, but the installation becomes cumbersome and requires additional space

Engineering Contradiction:
Improvemicro air bubble generationVSAvoidinstallation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent integrates the bubble generating function directly into the showerhead by incorporating bubble generating tubes within the showerhead body structure. This merging of functions eliminates the need for separate wall-mounted apparatus while maintaining micro air bubble generation capability, thereby reducing installation complexity and space requirements

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The showerhead is designed to perform multiple functions: water discharge, micro air bubble generation, and flow rate adjustment, all within a single integrated device. The bubble generating tubes are activated by the water flow itself, making the showerhead a multi-functional unit that eliminates dedicated separate apparatus

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If bubble generating tubes are expanded in discharge direction, then micro air bubbles are generated effectively, but the structure becomes more complex

Engineering Contradiction:
Improvebubble generation efficiencyVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The bubble generating component is segmented into multiple individual tubes arranged within the showerhead. Each tube is independently expanded in the discharge direction to create micro air bubbles. This segmentation allows the complex expansion function to be distributed across multiple simple tube structures rather than requiring a single complex mechanism

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of using a complex mechanical expansion mechanism, the patent employs the inverse approach by utilizing the water flow pressure itself to expand the bubble generating tubes in the discharge direction. The flowing water automatically performs the expansion function that would otherwise require complex mechanical devices

Inventive Principle:
Principle #13The other way round (Inversion)

3Ease of operation

If fluid regulator part is added to control bubble generation, then flow rate is adjustable, but the device complexity increases

Engineering Contradiction:
Improveflow rate adjustabilityVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The fluid regulator function is merged with the existing showerhead structure by positioning the regulator part within the body of the showerhead. This integration allows flow rate control without adding external complexity, as the regulator becomes an internal component of the unified showerhead assembly

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The fluid regulator part is designed to be operated by the user through simple external controls, while the internal mechanism automatically adjusts the flow rate to appropriate levels for bubble generation. The system serves itself by converting user input into automatic flow regulation without requiring complex external control systems

Inventive Principle:
Principle #25Self-service

AI summary

A showerhead for generating micro air bubbles includes: a body including an inflow part disposed at one end thereof for supplying shower water, and a discharge part disposed at the other end thereof for discharging the shower water supplied through the inflow part; a bubble-generating part coupled to the discharge part, and including bubble-generating tubes which expand in the discharge direction of the shower water; a fluid regulator part for opening/closing a portion of the bubble-generating tubes; and a shower part disposed in front of the bubble-generating part, and including shower holes for discharging shower water. Since the bubble-generating part for generating micro air bubbles is disposed within the showerhead, shower water including micro air bubbles can be used by simply replacing a typical showerhead with the above-described showerhead.
