Solution Overview

Problem

Conventional brake dust collectors are inefficient, aesthetically unappealing, and reduce maintainability, and cause stiffness degradation in vehicles, as they require separate devices and separate flow control elements for dust collection.

Innovation Solution

A brake dust collector with integrated filter modules in the leading and trailing portions of the housing, using a tangential air flow generated by disc rotation for dust collection, and a filter made of corrosion-resistant and heat-resistant metal, allowing for cleaning while mounted and minimizing stiffness loss.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-generated harmful factors

If a separate dust collector device is provided on one side of the caliper housing, then dust collection function is achieved, but aesthetics deteriorate and maintainability is reduced

Engineering Contradiction:
Improvedust collectionVSAvoidaesthetics and maintainability
Core Design Contradiction:
Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

The dust collection function is merged with the caliper housing by integrating filter modules directly into the housing structure. The housing includes filter module seats at its both ends where filter modules are coupled, eliminating the need for separate dust collector devices and achieving aesthetic integration while maintaining dust collection functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The caliper housing is designed to serve multiple functions: it provides structural support for the brake mechanism and simultaneously functions as a dust collection system through integrated filter modules. This multi-functionality eliminates the need for separate dedicated dust collection devices.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Device complexity

If filter modules are integrated into the housing, then aesthetics are maintained and maintainability is improved, but stiffness degradation may occur

Engineering Contradiction:
Improveaesthetics and maintainabilityVSAvoidhousing stiffness
Core Design Contradiction:
Device complexityVSStrength

Solution Approach 1:

The housing is segmented into functional zones including pad module seats and filter module seats at its both ends. This segmentation allows strategic placement of filter modules without compromising the overall structural integrity of the housing, as the reinforcement portions are positioned to maintain stiffness in critical areas.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The housing includes reinforcement portions made of corrosion-resistant and heat-resistant metal that are integrated with the main housing structure. These reinforcement portions act as composite structural elements that compensate for any stiffness loss caused by filter module integration while providing enhanced durability.

Inventive Principle:
Principle #40Composite materials

3Object-generated harmful factors

If conventional separate dust collectors are used, then dust collection is achieved, but cleaning and maintenance require device removal from vehicle

Engineering Contradiction:
Improvedust collectionVSAvoidfilter cleaning accessibility
Core Design Contradiction:
Object-generated harmful factorsVSEase of repair

Solution Approach 1:

The filter modules are designed to be accessible for cleaning while the brake assembly remains installed on the vehicle. The housing structure allows washing liquid to be applied to the filter modules through the filter module seats, enabling maintenance without removing the entire device from the vehicle.

Inventive Principle:
Principle #25Self-service
