Solution Overview
Problem
Existing filter cleaning devices are inefficient and difficult to use on various surfaces due to water accumulation, which prevents proper spinning and debris removal, especially in pleated filters like pool and spa filters.
Innovation Solution
A portable filter cleaning system with a conical retainer and drainage features that allows water to drain from the filter interior, combined with a support rod and bearing system for smooth spinning, enabling effective debris removal on both hard and uneven surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a filter is cleaned using a spinning device, then debris removal is improved, but the filter becomes difficult to spin when water accumulates inside
Solution Approach 1:
The patent extracts water from the filter interior during the cleaning process by positioning the filter at an angle that allows water to drain out through the bottom aperture. This prevents water accumulation that would otherwise hinder spinning and maintains ease of operation while preserving debris removal efficiency.
Solution Approach 2:
The filter is positioned at a dynamic angle (not perfectly vertical) during cleaning to facilitate water drainage. This dynamic positioning allows water to exit the filter while the filter continues to spin effectively for debris removal, resolving the contradiction between spinning ease and cleaning effectiveness.
2Ease of manufacture
If water is sprayed into the filter for cleaning, then debris is loosened, but water accumulates and makes the filter heavy
Solution Approach 1:
The system extracts water from the filter by positioning it at an angle during cleaning, allowing gravity to drain water out through the bottom aperture. This continuously removes water weight during the cleaning process, preventing excessive weight accumulation while maintaining effective water spray cleaning.
Solution Approach 2:
The cleaning process utilizes periodic spraying interspersed with drainage periods where the filter is allowed to spin and drain water. This periodic cycle of spraying and draining maintains cleaning effectiveness while preventing excessive water accumulation and weight gain.
3Stability of the object's composition
If the filter is positioned vertically for stable support, then stability is improved, but water drainage from the filter interior is hindered
Solution Approach 1:
The filter is positioned at an asymmetric angle (tilted from vertical) during cleaning rather than perfectly vertically. This asymmetric positioning creates a drainage path for water to exit through the bottom aperture while maintaining sufficient stability for operation, resolving the contradiction between stability and water drainage.
Solution Approach 2:
The solution addresses the drainage problem by introducing a spatial dimension - tilting the filter at an angle rather than keeping it vertical. This dimensional change creates a gravity-driven drainage path while maintaining operational stability, eliminating water accumulation without sacrificing stability.
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 system effectively drains water from the filter during cleaning, allowing for efficient debris removal using centrifugal force, making it suitable for various surfaces and ensuring stable, smooth operation.
Implementation Method 1
The conical retainer of the bottom filter retainer may be configured with drainage slots to allow water from within the interior of the filter to drain out during cleaning
Implementation Method 2
A bearing may include ball bearings to provide low friction engagement with the support rod
Implementation Method 3
Some devices have been described for spinning the filter in an effort to use centrifugal force to remove the debris from the pleats

AI summary
A portable filter cleaning assembly is configured to retain a filter on support rod and allow the filter to spin from a spray of water. The spinning filter releases debris from the filter surface through centrifugal force. The assembly has drainage features to ensure proper drainage of water collected within the interior of the filter and enable proper spinning from the spray of water. The assembly utilizes a support rod with a bottom filter retainer that is conical in shape for engaging with the filter aperture. The bottom filter retainer may further have a bearing that enables the filter to rotate freely about the rod with very little force. The assembly may include a stand for securing the support rod on a hard surface, such as concrete or on an uneven lawn surface.
