Adapter Filter Fixing Air Cleaner for High-Performance Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air cleaners for high-performance vehicles face challenges with complex structures, increased manufacturing costs, and difficulty in filter replacement due to bolt or spring fixing mechanisms, which hinder repairability and efficiency.
Innovation Solution
An adapter filter fixing type air cleaner with a circular filter that uses a wedge-shaped filter adapter and inclined filter arrangement, eliminating the need for bolts or springs to provide a stable and easy filter replacement mechanism, while maintaining high purification performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bolt fastening structure is used to fix the circular filter, then the filter can be securely fixed, but the structure becomes complex and manufacturing cost increases
Solution Approach 1:
The invention extracts and eliminates the complex bolt fastening structure and adapter from the air cleaner system. Instead of using bolts and separate adapters, the filter is directly fixed to the air cleaner body through an integrated fixing structure, removing unnecessary components while maintaining secure filter fixation.
Solution Approach 2:
The fixing structure is merged directly into the air cleaner body, combining the filter mounting function with the housing structure. This integration eliminates the need for separate adapters and bolt fastening mechanisms, simplifying the overall structure while ensuring reliable filter fixation.
2Ease of operation
If a spring support structure is used to fix the circular filter, then the filter can be easily replaced, but the mold cost and manufacturing cost increase
Solution Approach 1:
The invention removes the spring support structure from the air cleaner system. The spring mechanism, along with its associated attachment parts and support structures, is extracted and replaced with a simpler integrated fixing structure that achieves the same filter retention function without requiring complex molding or additional components.
Solution Approach 2:
The fixing mechanism transitions from an elastic spring-based system to a rigid integrated structure. This parameter change in the fixing approach eliminates the need for spring materials and complex attachment mechanisms, reducing mold complexity and manufacturing costs while maintaining ease of filter replacement.
3Ease of operation
If a clamp structure is used in a square filter air cleaner, then the filter replacement is convenient, but the penetration area and suction pressure are reduced
Solution Approach 1:
The invention adopts a circular filter design with curved geometry instead of a square filter with clamp structures. The circular shape allows for a larger penetration area and better airflow characteristics, while the integrated fixing structure provides convenient filter replacement without requiring external clamps that would reduce the effective area.

AI summary
An air cleaner is provided. The air cleaner includes an air cleaner body and air cleaner cover that are coupled to each other to form an internal space for mounting a filter and that are clamped and separated through a cover clamp. The filter purifies air that is introduced through a duct inlet into air which is to be discharged through a hose outlet. A filter fixer is formed in the internal space to seat the filter and forms a filter holding force to block swaying of the filter. Additionally, a filter adapter is mounted into or detached from the internal space and is inserted into the internal space to form a filter fixing force for fixing the filter.
