Brake Dust Collector Housing With Guide Pins Against Backflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brake dust collectors face inefficiencies due to backflow issues and high manufacturing and maintenance costs associated with large filter sizes, which are exacerbated by the high performance and high-speed operations of caliper brakes.
Innovation Solution
A brake dust collector design featuring guide pins to direct brake dust towards a filter assembly while preventing backflow, with a detachable filter assembly and reduced filter size, integrated into a housing that surrounds the disc and caliper brake, reducing the need for large filters and enhancing collection efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filter occupying a relatively large area is applied along the inner circumferential surface of the housing, then dust collection effectiveness is improved, but manufacturing cost and maintenance cost increase
Solution Approach 1:
The housing is divided into a leading portion and a trailing portion, with the filter selectively applied only to the trailing portion where dust collection is most needed. This segmentation allows the filter to cover only the critical area rather than the entire inner circumferential surface, reducing material costs and simplifying manufacturing while maintaining effective dust collection.
2Reliability
If a filter occupying a relatively large area is applied along the inner circumferential surface of the housing, then dust collection effectiveness is improved, but maintenance cost increases due to filter replacement and filter damage
Solution Approach 1:
By dividing the housing into leading and trailing portions and applying the filter only to the trailing portion, the filter area is reduced. This smaller, localized filter is less prone to damage and requires less frequent replacement, thereby reducing maintenance costs while still effectively collecting dust at the critical trailing edge where dust accumulates.
3Productivity
If fluid flows into the housing at high velocity and flow rate to collect dust, then dust collection speed is improved, but backflow occurs which lowers collection efficiency
Solution Approach 1:
The housing structure is designed with a trailing portion that dynamically manages fluid flow by creating a controlled flow pattern. The trailing portion's geometry and the selective filter placement work together to guide the high-velocity fluid flow through the dust-laden area while preventing backflow, thus maintaining both high collection speed and high efficiency.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively reduces brake dust discharge, improves collection efficiency, and decreases manufacturing and maintenance costs by guiding dust directly to a smaller filter, thereby minimizing pollutants and operational expenses.
Implementation Method 1
a plurality of guide pins protruding from an inner side wall of the housing in an axial direction of the disc and extending from an area where the brake dust is discharged toward an inner circumferential surface of the housing
Implementation Method 2
an area where the brake dust is discharged toward an inner circumferential surface of the housing
