Find Innovative SolutionsGenerate Solutions
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, using a support rod with bearings for smooth spinning and a stand or spike for stability on different surfaces, enabling effective debris removal through centrifugal force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a filter is cleaned using a spray of water, then debris is removed from the filter, but water accumulates inside the filter making it heavy and preventing proper spinning
Solution Approach 1:
The patent extracts the harmful element (water) from the filter interior by providing drainage pathways through the support rod and base structure. Water is channeled out through openings in the base, preventing accumulation and maintaining the filter's ability to spin freely during cleaning operations.
Solution Approach 2:
The support rod acts as an intermediary structure that provides both mechanical support and drainage functionality. It includes internal channels that mediate water flow from the filter interior to the exterior, resolving the contradiction between maintaining structural support and enabling water drainage.
2Productivity
If a filter cleaning device is designed to spin the filter for centrifugal cleaning, then debris removal is improved, but the device becomes difficult to use on various surfaces due to instability
Solution Approach 1:
The patent employs dynamic stabilization where the base structure can adapt to different surface conditions. The base includes features that allow it to stabilize on various surfaces (hard surfaces, uneven ground, grass) while maintaining the vertical orientation needed for effective filter spinning and centrifugal cleaning.
Solution Approach 2:
The cleaning device is designed with universal applicability to multiple surface types. The base structure incorporates elements that function effectively on hard surfaces, uneven terrain, and grassy areas, making the device versatile and easy to deploy in various outdoor cleaning scenarios.
3Productivity
If water is not drained from the filter interior, then the filter structure remains simple, but water accumulation prevents proper cleaning and causes the filter to tip over
Solution Approach 1:
The patent merges multiple functions into the support rod structure: mechanical support, water drainage channeling, and structural stabilization. By combining these functions in a single integrated component, the drainage system adds necessary functionality without proportionally increasing overall device complexity.
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, allowing it to spin freely and efficiently remove debris, making it versatile for use on both hard and uneven surfaces without tipping over.
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.
