Pipe Insert Structure for Extrudable Nano-Bubble Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for generating nano-bubbles in plumbing systems face challenges such as high costs, complex installation procedures, and inefficiencies due to differences in thickness between main walls and dividing walls, leading to difficulties in extrusion molding and reduced nano-bubble generation efficiency.
Innovation Solution
A pipe insert with continuously formed dividing walls and space dividers, which can be extrusion-molded without significant thickness differences, is inserted into plumbing pipes to increase the friction surface area, allowing for efficient nano-bubble generation without additional devices or space, using a main wall with spacer protrusions to maintain the gap between the insert and pipe.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the main wall is thickened to prevent expansion, then the fluid path member can tolerate inflow pressure, but it causes difficulty in extrusion molding due to large thickness difference with dividing walls and increases raw material cost
Solution Approach 1:
The insert is divided into multiple thin dividing walls that create multiple fluid paths, eliminating the need for a thick main wall. Each dividing wall is thin and can be uniformly extruded, solving the molding difficulty while maintaining pressure tolerance through the collective structure of multiple walls
Solution Approach 2:
The insert with thin dividing walls is nested inside an existing pipe, which provides the outer structural support and pressure containment. This eliminates the need for a thick main wall in the insert itself, as the pipe serves as the outer protective structure
2Productivity
If dividing walls are formed densely to expand friction surface, then nano-bubble generation efficiency improves, but the thickness difference between main wall and dividing walls increases, causing extrusion molding difficulties
Solution Approach 1:
All walls in the insert (dividing walls and end walls) are made with uniform thin thickness, creating a homogeneous structure that can be easily extruded. This uniform thinness allows dense arrangement of dividing walls to maximize friction surface area without creating thickness variation that would complicate molding
Solution Approach 2:
Instead of increasing main wall thickness to provide structural support, the solution moves to the longitudinal dimension by creating multiple thin dividing walls arranged densely along the length of the insert. This increases the friction surface area through dimensional arrangement rather than thickness increase
3Strength
If additional expansion prevention members are fitted outside the insert, then expansion can be prevented, but the installation procedure becomes cumbersome and requires excessive labor hours
Solution Approach 1:
The expandability prevention function is merged directly into the insert structure by making the insert itself rigid through its multiple dividing wall configuration, eliminating the need for separate expansion prevention members. The insert is designed to maintain its shape inherently through its structural design
Solution Approach 2:
The insert structure itself provides the expansion prevention capability through its rigid framework of multiple dividing walls, without requiring external assistance from separate expansion prevention members. The structure is self-sufficient in preventing expansion

Implementation Method 1
in the case where friction pressure is applied to a gas-liquid mixed fluid in which oxygen is mixed in the water, the fluid generates heat, and its bubbles become tiny and smooth, as a result of reaction against the friction
Implementation Method 2
the fluid generates heat, and its bubbles become tiny and smooth, as a result of reaction against the friction
Implementation Method 3
the bubbles, included in the gas-liquid mixed fluid, in order to reduce frictional resistance as illustrated in FIG. 1, are tensile-strained along the friction surface, and then split into smaller ones and become tiny until nano-bubbles are generated
