Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brake dust particle filters require significant installation space and are not suitable for retrofitting by end users due to the need for additional fastening points, which is a challenge in modern brake assemblies where space is limited.
Innovation Solution
A brake dust particle filter that closes the lining inspection opening of the brake caliper with a precise fit, using a filter medium and support designed to be inserted into the opening, reducing radial space requirements and allowing easy retrofitting by end users, with a filter medium that can withstand high temperatures and is designed for efficient particle separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a brake dust particle filter is installed to capture brake abrasion particles, then particle separation efficiency is improved, but installation space requirements increase
Solution Approach 1:
The filter element is inserted into the existing lining inspection opening of the brake caliper, nesting the filtration function within the existing structural space. This eliminates the need for additional external housing and reduces installation space requirements while maintaining particle separation efficiency.
Solution Approach 2:
The filter element uses a thin, flexible filter medium that can be contained within a compact cylindrical housing. This thin-film approach minimizes the radial and axial dimensions of the filter assembly, allowing it to fit within the limited space of the lining inspection opening.
2Reliability
If a brake dust particle filter with housing is used to enclose brake disc circumferentially, then particle capture capability is improved, but device complexity increases
Solution Approach 1:
The invention extracts only the essential filtration function from the complex housing structure of prior art filters. By using a simple cylindrical housing with a filter element that inserts into the existing lining inspection opening, the solution eliminates the need for complex fastening systems, suction lines, and large enclosing housings while maintaining effective particle capture.
Solution Approach 2:
The filter element serves multiple functions within a single compact component: it filters brake dust particles, maintains structural integrity under thermal loading, and integrates with the existing brake caliper lining inspection opening. This multi-functionality reduces the need for additional separate components and simplifies the overall device.
3Reliability
If additional fastening points are created for brake dust particle filter installation, then filter security is improved, but ease of operation deteriorates
Solution Approach 1:
The filter element is designed to be self-contained with an integrated sealing mechanism that creates a precise fit within the lining inspection opening. The filter medium and support structure work together to secure the filter element without requiring additional fastening points or complex installation procedures, enabling end users to perform retrofits easily.
