Brake Dust Filter Cartridge Coupling for Compact Sealed Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brake dust particle filter arrangements face challenges in achieving a long service interval within limited installation space and securely storing harmful fine dust particles, leading to cumbersome installation and maintenance processes that may result in dust particle escape.
Innovation Solution
The filter arrangement incorporates a coupling element that includes an air outlet duct and air outlet, facilitating easy installation and reducing the need for additional construction elements, thereby minimizing the risk of dust particle escape during maintenance or replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the filter arrangement is installed at the brake assembly with separate air inlet and air outlet connections, then the filtering function is achieved, but the installation becomes cumbersome and requires excessive movement of the filter arrangement
Solution Approach 1:
The air inlet duct and air outlet duct are merged into a single coupling element that attaches to the brake assembly. This integration eliminates the need for separate connection operations for air inlet and air outlet, allowing the filter arrangement to be installed by simply attaching the coupling element to the brake assembly flange, thereby simplifying the installation process while maintaining proper air flow paths.
2Ease of repair
If the filter arrangement is removed from the brake assembly for maintenance, then the filter can be replaced, but fine dust particles may escape during the removal process
Solution Approach 1:
The filter arrangement is segmented into a removable filter cartridge and a stationary coupling element that remains attached to the brake assembly. During maintenance, only the filter cartridge needs to be removed and replaced, while the coupling element with its integrated air inlet and outlet ducts remains in place. This segmentation allows for easy filter replacement without requiring complete disassembly, and the stationary coupling element ensures that air flow paths remain sealed, preventing dust particle escape during maintenance operations.
3Reliability
If additional construction elements are added for air inlet and air outlet connections, then proper air flow is ensured, but the installation space requirement increases
Solution Approach 1:
The air inlet duct and air outlet duct are merged into a single coupling element that attaches to the brake assembly flange. This integration consolidates multiple air flow paths into one compact component, ensuring reliable air inlet and outlet connections while minimizing the space required for installation. The coupling element design allows proper air flow separation and direction without requiring additional separate construction elements, thereby maintaining reliability while reducing installation space requirements.

Function Achieved in This Case
The solution allows for a compact filter arrangement design that reduces installation complexity, extends service intervals, and securely confines fine dust particles, minimizing health hazards for service personnel.
Implementation Method 1
The polluted air passes through the filter medium within the filter cartridge. The (fine) dust particles are separated from the polluted air into the filter medium.
