Filter Module Screw-Connected Pump and Filter Housings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter modules require significant installation effort and cost due to the use of separate screws for connecting the pump and filter housings, which complicates the connection process and increases logistics and storage costs.
Innovation Solution
A filter module design featuring complementary screw connections between the pump and filter housings, eliminating the need for separate fastening means like screws, allowing for a simple screw-in connection and enabling a three-part pump housing for enhanced flexibility and maintenance access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate screws are used to connect the pump housing and filter housing, then the connection is reliable and secure, but the installation effort and complexity increase significantly
Solution Approach 1:
The patent merges the fastening function into the thread connection itself. The pump housing (3) is directly screwed onto the filter housing (5) using integrated threaded connections, eliminating the need for separate screws and fastening means. This combining of the connection and fastening functions reduces the number of components while maintaining secure attachment.
Solution Approach 2:
The patent extracts and removes the separate fastening means (screws) from the connection system. By using directly integrated threaded connections on both housings, the fastening function is embedded into the connection structure itself, eliminating the need for additional fastening components and simplifying the overall assembly.
2Reliability
If separate screws and fastening means are used, then secure fastening is achieved, but storage and logistics costs increase
Solution Approach 1:
The fastening function is merged into the thread connection structure itself. The threaded connections are integral to the pump housing and filter housing, eliminating the need for separate fastening components. This reduces the total number of parts while maintaining secure fastening through the threaded engagement.
3Reliability
If multiple separate fastening components are used, then reliable connection is achieved, but installation time and manual effort increase
Solution Approach 1:
The pump housing is segmented into three separate sections (housing cover (8), middle part (9), lower part (10)) that can be independently assembled and disassembled. This segmentation allows for simplified installation and maintenance, as each section can be handled separately while maintaining stable connections through integrated threaded joints.
Solution Approach 2:
The connection and fastening functions are merged into a single threaded connection operation. The pump housing is directly screwed onto the filter housing in one continuous motion, eliminating the need for multiple separate fastening steps and reducing installation time while maintaining connection stability.
4Ease of manufacture
If the pump housing is made as a single piece, then manufacturing is simpler, but maintenance access and flexibility are reduced
Solution Approach 1:
The pump housing is divided into three separate sections: housing cover (8), middle part (9), and lower part (10). This segmentation enables easy disassembly for maintenance and inspection of internal components while allowing each section to be manufactured separately using simple processes. The sections are reassembled using threaded connections for stable reconstruction.
5Ease of repair
If the pump housing is divided into multiple sections, then maintenance access and flexibility are improved, but the number of components increases
Solution Approach 1:
The pump housing is segmented into three manageable sections that can be easily assembled and disassembled for maintenance. Each section has a clear function and can be handled independently, improving accessibility while keeping the overall structure relatively simple through the use of standard threaded connections.

AI summary
A filter module is disclosed. The filter module includes a pump with a pump housing and a filter device with a filter housing. A first thread is arranged on the pump housing, and a second thread configured complementary to the first thread is arranged on the filter housing, so that the pump is able to be screwed via the pump housing to the filter housing of the filter device. The pump housing includes a housing cover, a middle part and a lower part. The housing cover is screwed to the middle part and the middle part is screwed to the lower part.
