Filter System Self-Cleaning via Fluid Control Suction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter systems for large vehicles and facilities face energy inefficiencies due to the use of secondary blowers for debris removal and costly ducting, which can lead to reduced system efficiency and filter lifespan if the blower fails.
Innovation Solution
A filter system that integrates a filter, a fluid control device, and a conduit within a common housing, where the fluid control device changes the characteristics of the filtered fluid to create suction for debris removal without a secondary blower, using a conduit shaped to control pressure and velocity to direct the debris-laden fluid mixture for efficient evacuation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a secondary blower is used to remove debris from the filter, then debris removal function is provided, but energy consumption increases and system reliability decreases
Solution Approach 1:
The patent combines the debris removal function with the existing fluid control device (blower or compressor) by integrating a conduit system that utilizes the device's output fluid to create suction for debris evacuation. This eliminates the need for a separate secondary blower, reducing energy consumption while maintaining reliable debris removal through the unified system.
Solution Approach 2:
The system uses its own operational resources (the fluid control device's output fluid) to perform the debris removal function. The conduit is configured to receive fluid from the control device and use it to create suction that draws debris from the filter, allowing the system to self-clean without requiring additional external energy input or separate active components.
2Ease of manufacture
If ducting is used to couple the filter with the main blower, then fluid transport is achieved, but manufacturing cost increases and system efficiency decreases
Solution Approach 1:
The patent merges the ducting function with the existing housing structure by configuring the conduit to be integrated within the housing that contains the filter and fluid control device. This eliminates the need for separate external ducting components, reducing manufacturing costs while maintaining efficient fluid transport through the optimized internal conduit geometry.
3Ease of operation
If ducting is used to couple the filter with the main blower, then fluid transport is achieved, but system complexity and cleaning difficulty increase
Solution Approach 1:
The patent integrates the conduit directly into the housing structure that contains the filter and fluid control device, eliminating separate external ducting systems. This unified design simplifies the overall system architecture, reduces the number of components that require assembly and maintenance, and makes the system easier to clean and service.

AI summary
A filter system and method include a filter configured to receive a first fluid mixture via an inlet. The first fluid mixture includes a first fluid and debris. The filter is shaped to separate a portion of the debris from the first fluid. A fluid control device is fluidly coupled with the filter. The fluid control device receives the first fluid from the filter and changes a characteristics of the first fluid. A conduit is fluidly coupled with the filter and a second fluid source. The conduit receives the debris from the filter and a second fluid from the second fluid source. The conduit combines the debris with the second fluid to form a second fluid mixture within the conduit. The conduit is shaped to control one or more of a pressure or a velocity within the conduit to direct the second fluid mixture through the conduit toward an outlet.
