Solution Overview

Problem

Existing brake dust collectors for motor vehicles are not service-friendly and require the entire constructive unit to be exchanged for maintenance, which is inefficient and costly.

Innovation Solution

A brake dust collector design featuring an exchangeable filter element that can be easily inserted and removed from a filter receptacle, with the receptacle being separate from the brake caliper and having air passages with exit openings to assist in dust collection and prevent dust escape, allowing for extended service life of the receptacle without needing to replace it along with the filter.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the filter element and filter receptacle are designed as a non-separable constructive unit, then the structural integrity and simplicity is improved, but the ease of maintenance and serviceability deteriorates

Engineering Contradiction:
Improvestructural simplicityVSAvoidmaintenance serviceability
Core Design Contradiction:
Device complexityVSEase of repair

Solution Approach 1:

The brake dust collector is divided into separable components: the filter element and the filter receptacle. The filter element can be removed independently from the receptacle through a housing opening, allowing maintenance without replacing the entire unit. This segmentation enables the filter element to be serviced separately while maintaining structural integrity of the overall system.

Inventive Principle:
Principle #1Segmentation

2Reliability

If the entire constructive unit is exchanged for maintenance, then the reliability is improved, but the loss of time and productivity deteriorates

Engineering Contradiction:
Improvesystem reliabilityVSAvoidmaintenance time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

By separating the filter element from the filter receptacle, only the filter element needs to be replaced during maintenance, not the entire constructive unit. This reduces maintenance time significantly while ensuring the filter element is reliably replaced when needed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The filter element is designed as a replaceable component with a defined service life, while the filter receptacle is a durable housing that remains in place. This allows the short-lived filter element to be exchanged periodically without replacing the long-lived receptacle structure.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Ease of operation

If the housing opening is located on the side facing the brake disk, then the accessibility is improved, but the dust escape risk increases

Engineering Contradiction:
Improvefilter accessibilityVSAvoidbrake dust escape
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The housing opening is positioned on the side of the filter receptacle facing away from the brake disk, serving as an intermediary access point. This allows filter element removal without direct exposure to the brake disk area, reducing dust escape risk while maintaining serviceability through the designated opening.

Inventive Principle:
Principle #24Intermediary (Mediator)

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

This design enables easy and cost-effective maintenance by allowing the filter element to be exchanged independently, extending the service life of the filter receptacle and ensuring efficient brake dust collection without the need for frequent replacements of the entire unit.

Implementation Method 1

the produced brake dust is exclusively accelerated by the rotational movement of the brake disk or by flows across the brake disk in the direction of the filter element where it is collected

Methodology Applied
Scientific EffectCentrifugal force: Centrifugal Force

Implementation Method 2

a filter element which is arranged at the radial outer edge of the brake disk and is extending across a defined angle section of the brake disk

Methodology Applied
Scientific EffectFiltration: Filter (physical)

Implementation Method 3

an air passage with air exit openings oriented toward the brake disk

Methodology Applied
Scientific EffectFluid flow:

AI summary

A brake dust collector for a motor vehicle for collecting brake dusk of a vehicle wheel brake has a dust collecting device with a filter element arranged in a filter receptacle. The filter element is designed as an exchangeable filter and is arranged exchangeable in a receiving space provided in the filter receptacle. The filter receptacle has a housing opening communicating with the receiving space. Through the housing opening the filter element is inserted into the receiving space and removed from the receiving space. The housing opening is located on a side of the filter receptacle that is facing away from the vehicle wheel brake.
