Air Filter Group With Nested Cylindrical Cartridge For Compact Engine Intake
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air filter groups for internal combustion engines are bulky and require frequent maintenance, occupying valuable space in the engine compartment due to their design, which limits the efficient use of internal spaces and necessitates periodic replacement of the filter wall.
Innovation Solution
The air filter group features a filter cartridge with a support body having a chamber with a base and an upper wall, where the filter wall is fixed, allowing for a compact design that separates the dirty side from the clean side, optimizing internal space usage and facilitating easy maintenance by enabling the filter surface to be positioned against tubular walls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional filter box with large dimensions is used to contain the filter wall, then the filter wall can effectively retain solid particles, but the filter group occupies considerable space in the engine compartment
Solution Approach 1:
The filter wall is nested within the support body structure, where the support body's chamber houses the filter wall in a compact arrangement. The filter wall is positioned within the chamber limited by the base and upper wall, creating a nested configuration that reduces overall volume while maintaining filtration functionality.
Solution Approach 2:
The invention transitions from a conventional box-shaped filter group to a tubular wall configuration. The filter wall is arranged along the tubular wall of the support body, utilizing the cylindrical geometry to achieve more efficient space utilization and reduce the overall footprint in the engine compartment.
2Ease of repair
If the filter wall is located in an easily-accessible position for maintenance, then the filter wall can be regularly replaced, but the available spaces in the engine compartment are limited
Solution Approach 1:
The filter group is segmented into modular components: the support body, the filter wall, and the casing. The filter wall is fixed to the support body which can be independently removed from the casing, allowing maintenance personnel to access and replace the filter wall without removing the entire filter group, thus improving ease of repair while minimizing space requirements.
3Reliability
If the filter wall blocks solid particles effectively, then engine protection is improved, but the filter wall blocks more or less rapidly requiring frequent replacement
Solution Approach 1:
The filter wall is designed as a disposable component that can be quickly removed and replaced. When the filter wall becomes blocked and requires replacement, the entire support body with the filter wall can be rapidly removed from the casing and replaced with a new unit, minimizing maintenance downtime and allowing frequent replacement without significant time loss.

Function Achieved in This Case
This configuration allows for efficient air filtration while minimizing space usage in the engine compartment and simplifies maintenance by allowing easy access and replacement of the filter cartridge, providing a more rational and cost-effective solution compared to traditional systems.
Implementation Method 1
a filter wall made of porous material which retains the solid particles and allows the air part to pass
