Filtration Module Angled Partial Screw Thread Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current filtration modules in the semiconductor industry face challenges such as difficulty in connecting and disconnecting due to complex flow configurations, require multiple directional forces for cartridge removal, and are limited to single cartridge designs, which complicates the filtration process and poses safety risks with toxic or corrosive fluids.
Innovation Solution
A filtration module design featuring a manifold and bowl joined in a fluid-tight manner with angled partial screw threads that allow for a one-step connection and disconnection of filtration cartridges, eliminating the need for multiple directional forces and enabling easier handling and replacement of cartridges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If bayonet connections with two-step process are used to join cartridge and bowl, then the connection can be made, but the removal process requires considerable force and hand tools
Solution Approach 1:
The patent inverts the conventional bayonet connection approach by using a simple latch mechanism where the cartridge is held in place by a latch that releases with a single motion. Instead of requiring rotational engagement and disengagement, the latch mechanism allows for easy one-handed removal by simply pressing a release button or lever, eliminating the need for hand tools and considerable force.
Solution Approach 2:
The patent extracts the complex rotational engagement mechanism from the connection system and replaces it with a simplified latch and release mechanism. The latch mechanism is designed to be released by a single directional motion, separating the holding function from the releasing function, thereby making cartridge removal as easy as pressing a release mechanism without requiring rotational force or tools.
2Device complexity
If single cartridge design is used, then the module structure is simple, but the filter surface area per unit volume is limited
Solution Approach 1:
The patent segments the filtration system into multiple cartridge units that can be independently installed within the bowl. Each cartridge is a separate, self-contained filtration element with its own latch mechanism. This segmentation allows for multiple cartridges to be arranged side-by-side in the bowl, maximizing the total filter surface area while maintaining a relatively simple overall module structure that can be easily assembled and disassembled.
3Reliability
If complex flow configuration with in-line flow is used, then filtration can be performed, but connection to process equipment becomes difficult
Solution Approach 1:
The patent segments the module into a separate bowl assembly that can be independently connected to process equipment. The bowl is designed with standardized connection interfaces that allow for straightforward attachment and detachment from the filtration cartridges and process equipment. This segmentation eliminates the need for complex in-line flow configurations, making the module easier to connect while maintaining reliable filtration through the standardized cartridge-bowl assembly.

Function Achieved in This Case
This design enhances ease of use, reduces the risk of contamination, and allows for multiple cartridges to be integrated, increasing filter surface area per unit volume while ensuring a secure and leak-proof seal, even under back pressure.
Implementation Method 1
The support outlet has two or more angled structures, such as partial threads, that engage with angled mating structures of the outlet conduit of the manifold with less than a full turn
Implementation Method 2
The porous purification membrane may be used to remove particulate, molecular, ionic, or combination of these contaminants from a liquid

AI summary
A purification module is provided comprising a plurality of purification cartridges, a support for the cartridges, a manifold and a bowl. In one embodiment the support for the cartridges has two pitched partial screw threads on opposing surfaces which mate with pitched screw flights on the manifold when the partial screw threads are rotated into the screw flights. The support includes fluid passageways for directing filtered fluid from the filtration cartridges, through the support and into the manifold. In another embodiment, a purification module is provided comprising a purification cartridge, a manifold and a bowl. The purification cartridge has two pitched partial screw threads on opposing surfaces of the cartridge outlet which mate with screw flights on the manifold when the partial screw threads are rotated into the mating screw flights.
