Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ultra fine bubble production devices require additional processing for current control plates, which can cause friction, reduce flow rates, and accumulate debris, leading to narrowed passages.
Innovation Solution
A pipe with a helical guide member and a carbon-based porous gas bubble production medium, where the liquid current inflow is offset from the axial center, allowing a helical flow without additional components and reducing debris accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If current control plates are provided in the outer shell layer to generate helical liquid current, then helical flow is achieved, but friction occurs between liquid and plates causing flow rate decrease
Solution Approach 1:
The invention extracts and eliminates the current control plates from the system. Instead of using multiple plates to create helical flow, the patent uses a single guide member with a helical guide groove that achieves the same flow shaping function without the friction and flow rate loss caused by multiple plate interfaces.
Solution Approach 2:
The invention merges the functions of multiple current control plates into a single integrated guide member. The guide member with its helical guide groove combines the flow guidance and helical motion generation functions that previously required separate plates, reducing friction surfaces and maintaining flow rate.
2Shape
If current control plates are provided in the outer shell layer to generate helical liquid current, then helical flow is achieved, but dust and suspended matter accumulate in the plates narrowing the passage
Solution Approach 1:
The invention removes the current control plates that were prone to accumulating dust and suspended matter. The single guide member with smooth helical guide groove eliminates the multiple plate surfaces where debris could accumulate, maintaining consistent passage cross-section and preventing flow restriction.
3Shape
If multiple current control plates are provided to generate helical liquid current, then helical flow is achieved, but additional manufacturing processes are required for the outer shell layer
Solution Approach 1:
The invention consolidates the helical flow generation function into a single guide member that can be manufactured separately and installed in the outer shell layer. This eliminates the need for complex multi-step manufacturing processes to create multiple current control plates and their associated grooves in the shell layer.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Maintains high flow rates and reduces debris accumulation, enabling efficient production of ultra fine bubbles with reduced noise and stress on aquatic organisms.
Implementation Method 1
a compression device (22) for pressure-feeding gas to the pipe (25), and a gas bubble production medium (23) that releases gas pressure-fed by the compression device (22) to liquid in the pipe (25) as an ultra fine bubble
Implementation Method 2
the guide member (30) has a helical guide groove (30ba), thereby a liquid current from the liquid current inflow port (25c) is guided in a helical manner by the guide groove (30ba)
