Layered Air Filter Layout for Unobstructed High-Pressure Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air filters, such as oil-water separators, suffer from obstructed airflow due to small air inlets and outlets, affecting airflow pressure and filtration efficiency, particularly in applications like automobile painting where high-pressure air is required.
Innovation Solution
The air filter design includes a centrifugal separation assembly with a centrifugal mounting portion and filtration assemblies featuring '7'-shaped import pipe fittings, filtration shells, and filtration apparatuses with annular air guide channels, allowing for unobstructed airflow and layered filtration, along with a pressure-regulating assembly to manage airflow pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the air inlet and air outlet are disposed in a compact arrangement around the connecting screw, then the mounting head structure is compact, but the airflow channel becomes obstructed and filtration efficiency deteriorates
Solution Approach 1:
The patent transitions from a planar arrangement of air inlet and outlet to a three-dimensional spatial configuration. The air inlet is positioned at the bottom of the mounting head while the air outlet extends laterally along the side surface, creating a spatial separation that avoids obstruction while maintaining compact overall dimensions. This dimensional change resolves the contradiction between structural compactness and airflow efficiency.
Solution Approach 2:
The air inlet channel and air outlet channel are nested within the mounting head body structure rather than being external additions. The channels are integrated into the mounting head's internal geometry, with the air inlet channel extending from the bottom interior and the air outlet channel forming a lateral passage. This nesting approach maintains compact external dimensions while providing unobstructed internal airflow paths.
2Area of stationary object
If the air outlet size is reduced to fit within the base dimensions, then the mounting head remains compact, but the airflow pressure and filtration effect deteriorate
Solution Approach 1:
The air outlet channel is designed with a curved lateral extension rather than a straight linear path. This curved configuration allows the air outlet to extend further from the mounting head in a space-efficient manner, increasing the effective outlet area without proportionally increasing the bounding box dimensions. The curvature enables better airflow expansion while maintaining a compact overall footprint.
3Ease of manufacture
If the air inlet is positioned in the middle surrounding the connecting screw, then the mounting structure is simplified, but the airflow circulation becomes obstructed
Solution Approach 1:
The air inlet is extracted from the traditional middle position surrounding the connecting screw and relocated to the bottom of the mounting head. This extraction allows the air inlet channel to be positioned independently of the screw connection area, eliminating the obstruction caused by the screw head blocking the airflow path. The connecting screw remains in its functional position while the air inlet operates from an unobstructed bottom location.
