Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation and servicing of conventional tube diffusers in wastewater treatment plants are labor-intensive and prone to leaks, leading to non-uniform bubble distribution and potential flooding of the air piping, requiring time-consuming and costly repairs.
Innovation Solution
A diffuser assembly with a flexible membrane captured by a diffuser body utilizing an integral perimeter edge frame, creating an airtight seal and eliminating the need for separate clamps, allowing for easier installation and reducing leak risks, with a design that includes a hollow-cylindrical structure for air distribution and a plug to prevent counterflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional tube diffusers are used with separate flexible membranes and support tubes, then the diffuser can be assembled from separate components, but the installation becomes labor-intensive and prone to leaks requiring skilled labor
Solution Approach 1:
The patent combines the flexible diffuser membrane and the rigid support tube into a single integrated diffuser assembly. The membrane is secured to the support tube through a integrated structure that eliminates the need for separate clamps or fastening mechanisms, thereby simplifying installation while maintaining manufacturing flexibility.
Solution Approach 2:
The integrated diffuser assembly serves multiple functions: the support tube provides structural rigidity and positioning, while the flexible membrane provides the diffuser surface. The combination creates a universal component that can be easily installed and replaced as a single unit, reducing the need for skilled labor.
2Ease of repair
If conventional tube diffusers are installed with separate components, then the diffuser can be serviced individually, but leaks cause non-uniform bubble distribution and require draining the tank for repairs
Solution Approach 1:
By integrating the membrane and support tube into a single assembly, the patent eliminates potential leak points at connection interfaces. The unified structure ensures uniform bubble distribution and prevents wastewater from entering the air piping, thereby improving reliability.
Solution Approach 2:
The integrated diffuser assembly is designed as a disposable component that can be easily replaced rather than repaired. This approach eliminates the need for draining the tank for repairs, as the entire assembly can be quickly swapped out, improving both reliability and ease of maintenance.
3Manufacturing precision
If conventional tube diffusers require skilled labor for installation, then proper installation can be achieved, but the installation process becomes time-consuming and costly
Solution Approach 1:
The integrated diffuser assembly eliminates the need for complex assembly steps requiring skilled labor. The unified structure with pre-secured membrane and support tube allows for quick installation by unskilled or semi-skilled workers, reducing both installation time and cost while maintaining proper installation quality.
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 solution simplifies installation, reduces leak occurrences, and enables the diffuser assembly to be used as a disposable part, minimizing material usage and weight while ensuring effective oxygenation and mixing in wastewater treatment tanks.
Implementation Method 1
Supplying pressurized air to the tube diffuser while the tube diffuser is immersed in wastewater has the effect of expanding the flexible diffuser membrane away from the support tube and causing the air to escape into the wastewater through a multiplicity of perforations
Implementation Method 2
a perimeter edge frame covering a covered portion of the perimeter edge bead such that the flexible diffuser membrane is retained to the diffuser body and an airtight seal is created therebetween
Implementation Method 3
A plug is at a bottom of the internal vertical tube opposite the opening

AI summary
A diffuser assembly (100) includes a flexible diffuser membrane (130) and a diffuser body (125). The flexible diffuser membrane defines a perimeter edge bead (135) along four edges. The diffuser body (125) defines an underlying body portion (145) underlying the flexible diffuser membrane, and a perimeter edge frame (170) covering a covered portion of the perimeter edge bead (135). The edge frame (170) defines an inside surface that conforms to an outside shape of the covered portion of the perimeter edge bead (135). The perimeter edge frame (170) is integral to the underlying body portion (145).
