Solution Overview
Problem
Current micro-bubble generators have an air intake channel that compromises the streamlined appearance and is costly to manufacture, leading to uncontrollable air intake and larger bubble sizes.
Innovation Solution
A micro-bubble generator design featuring an intake manifold and casing with internal air channels, a booster to increase water velocity, and a bubble generating tube with air inlet channels that allow ambient air to mix with water without external air inlets, utilizing a cutter to produce micro-bubbles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an air intake channel is provided on the outer casing to introduce air into the generator, then air can be introduced into the generator to generate bubbles, but the air intake channel leaves a hole in the outer casing that is not streamlined with the outer appearance and increases manufacturing complexity
Solution Approach 1:
The air intake channel is extracted from the outer casing and relocated to the internal structure. The casing maintains a streamlined appearance without external air intake holes, while air is introduced through internal channels formed by the arrangement of internal components such as the bubble generating tube and booster.
Solution Approach 2:
The air intake channels are nested within the internal structure of the generator. The bubble generating tube and booster are arranged to form air intake channels between them, allowing air to be introduced internally without compromising the external streamlined appearance of the casing.
2Ease of operation
If a traditional air inlet hole is used, then air can enter the generator, but the air inlet quantity is uncontrollable causing larger bubbles and compromising manufacturing simplicity
Solution Approach 1:
The air intake function is segmented into multiple controlled channels rather than a single large hole. The air is introduced through separate channels formed by the bubble generating tube and booster, allowing independent control of air intake quantity and improving manufacturing precision.
Solution Approach 2:
The air intake quantity is controlled by adjusting the dimensions and positioning of the internal channels rather than the size of an external hole. By changing the parameters of the internal air intake channels, precise control over air intake quantity and bubble size is achieved.
3Quantity of substance
If the air intake channel is made large to ensure sufficient air supply, then air can be introduced effectively, but the bubble size becomes larger than 50 mm and manufacturing cost increases
Solution Approach 1:
The air supply is segmented into multiple smaller channels instead of a single large channel. This segmentation allows sufficient total air supply while controlling individual bubble sizes to be 50 mm or less, improving manufacturing precision.
Solution Approach 2:
Different sections of the air intake system have different channel dimensions optimized for local requirements. The internal channels are designed with specific dimensions to control bubble size in different regions, ensuring uniform micro-bubble generation while maintaining sufficient overall air supply.
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 simplifies manufacturing, reduces costs, and allows for controlled air intake and bubble size, producing micro-bubbles efficiently while maintaining a streamlined appearance.
Implementation Method 1
a booster located inside the receiving chamber and an end of which is provided with a first water inlet in communication with the water inlet channel and the other end of which is provided with a first water outlet having an inner diameter smaller than that of the first water inlet such that the water velocity flowing out of the first water outlet is larger than that of the water flowing into the first water inlet
Implementation Method 2
when water flows out of the first water outlet, ambient air is sucked in via the first air inlet channel, the second air inlet channel and the third air inlet channel and mixed with the water
Implementation Method 3
a cutter located in the casing at a position corresponding to where the bubbles exit so that the bubbles are cut into micro-bubbles

AI summary
A micro-bubble generator has an intake manifold, a casing threadingly connected to the intake manifold, a first air inlet channel defined between threads of the intake manifold and the casing, a booster located inside the casing and having a gap defined between the casing and the booster to form a second air inlet channel and to communicate with the first air inlet channel, a bubble generating tube located inside the casing and having a third air inlet channel defined between the end faces of the bubble generating tube and of the booster. The booster includes a first water inlet and a first water outlet having an inner diameter smaller than that of the first water inlet so that water velocity at the first water outlet is faster than that at the first water inlet, which forces ambient air to enter the bubble generating tube via air inlet channels and to be mixed with water in the bubble generating tube to generate bubbles. Bubbles are cut into micro-bubbles after passing through the cutter and exit the bubble exit.
