Pulse Ring Assembly for Air Cleaner Retrofits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air cleaner systems require complex modifications to incorporate pulse cleaning technology, which can be inefficient and costly.
Innovation Solution
The pulse ring assembly is a self-contained unit that can be retrofitted between an air filter outlet and an engine intake, using a pulse jet apparatus to direct gas or fluid towards the air filter outlet, effectively cleaning dust and debris from the filter media without modifying the existing air filter system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If pulse cleaning technology is incorporated into existing air cleaner systems, then filter media life and filtering capacity are improved, but system complexity and modification requirements increase
Solution Approach 1:
The pulse ring assembly is divided into separate functional components: an outer tube with pulse ports, an inner tube for airflow, and a pulse jet apparatus. This segmentation allows each component to be optimized independently and facilitates retrofitting into existing systems without requiring complete system redesign.
Solution Approach 2:
The inner tube is nested within the outer tube, creating a compact dual-tube structure. The inner tube carries filtered air while the outer tube provides pulse cleaning functionality. This nesting arrangement minimizes space requirements and allows integration into existing air cleaner configurations without extensive modifications.
2Ease of manufacture
If a self-contained pulse ring assembly is used, then ease of installation is improved, but device complexity increases
Solution Approach 1:
The pulse ring assembly merges multiple functions into a single integrated unit: the outer tube with pulse ports, the inner tube, and the pulse jet apparatus are combined into one assembly that can be installed as a complete package. This merging simplifies installation procedures while the internal complexity is managed through modular design.
Solution Approach 2:
The pulse ring assembly is designed to perform multiple functions simultaneously: it provides pulse cleaning through the outer tube pulse ports, maintains filtered air flow through the inner tube, and can be retrofitted to various air cleaner configurations. This multi-functionality reduces the need for separate components and simplifies overall system integration.
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 pulse ring assembly enhances the filtering capacity and extends the life of air filter media by providing a simple and effective method for pulse cleaning, without the need for extensive modifications to the air cleaner system.
Implementation Method 1
The pulse jet apparatus may be configured to direct gas or fluid towards the air filter outlet (e.g., an outlet through which filtered air passes towards the engine intake) to force dust and debris off of filter media

AI summary
A pulse ring assembly for air cleaner systems that is adapted to produce a pulse ring of gas to clean a filter element. The air cleaner system may include an outer tube and an inner tube configured to receive the inner tube such that at least a portion of an interior surface of the outer tube faces at least a portion of an exterior surface of the inner tube. The outer tube may include a pulse port extending between the interior and exterior surfaces of the outer tube into an outer tube passageway. Filtered air may be configured to flow from a first filter cartridge, through the outer and inner tubes, and to an engine intake. The system may also include a pulse jet apparatus in fluid communication with the pulse port of the outer tube and configured to direct gas through the pulse port towards the first filter cartridge.
