Pump Assembly Integrated Brush Filter Cleaning Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional filter cleaning methods are inconvenient and often neglected due to the need for separate tools and removal of filters from systems, leading to reduced efficiency and potential damage from debris accumulation.
Innovation Solution
The development of pump assemblies with a built-in mechanism, featuring a manually-operated brush that rotates or translates to clean the filter screen, allowing for efficient debris removal without requiring separate tools or filter removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional filter cleaning methods are used (separate tools and filter removal), then the filter can be cleaned, but the cleaning process becomes inconvenient and time-consuming
Solution Approach 1:
The brush is integrated directly into the pump housing structure, merging the cleaning tool with the pump body. This eliminates the need for separate cleaning tools and allows users to clean the filter screen while the pump is installed, significantly improving convenience and reducing time loss.
Solution Approach 2:
The pump assembly provides its own cleaning capability through the integrated brush mechanism. Users can perform maintenance themselves without needing external tools or removing the filter, enabling self-service cleaning that is both convenient and time-efficient.
2Reliability
If the filter is cleaned less frequently due to inconvenient cleaning methods, then system maintenance is reduced, but debris accumulation causes reduced efficiency and potential damage
Solution Approach 1:
The integrated brush allows users to clean the filter screen before debris accumulation becomes problematic. By making cleaning convenient and accessible, users can perform preliminary maintenance actions regularly, preventing efficiency degradation and potential damage before they occur.
Solution Approach 2:
The easy-to-access cleaning mechanism empowers users to perform regular maintenance themselves, ensuring the filter is cleaned frequently enough to maintain system reliability and efficiency without requiring professional service or complex procedures.
3Ease of operation
If a built-in brush mechanism is added to the pump assembly, then filter cleaning becomes more convenient, but the device complexity increases
Solution Approach 1:
The brush is merged with the pump housing as an integrated component rather than a separate tool. This consolidation adds cleaning functionality while minimizing the increase in overall device complexity, as the brush shares the same structural space and mounting points within the existing pump assembly.
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
This solution enables effective and convenient filter cleaning, maintaining system efficiency and preventing damage from debris accumulation, as the brush can contact a significant portion of the filter surface during rotation or translation, facilitating regular maintenance.
Implementation Method 1
a manually-operated brush mounted adjacent to the filter screen, where the brush may be adapted to rotate while in contact with the filter screen
Implementation Method 2
manually rotating the brush to clean the filter screen

AI summary
Improved systems and methods for cleaning a filter are described, including apparatuses that include a built-in mechanism for cleaning a filter screen. The system can include a brush mounted in contact with a filter screen, adapted so that the brush can be moved to clean the filter screen. In some versions, the brush rotates with an axis of rotation perpendicular to a plane defined by a substantially planar filter screen. In other versions, the brush is adapted to be moved by a gravitational force along a surface of a filter screen upon removal of a pump housing from a pump well. In still other versions, a substantially cylindrical brush is mounted nested with a substantially semi-cylindrical filter screen, and the brush can be rotated while in contact with the filter screen and with an axis of rotation aligned with a longitudinal axis of the filter screen.
