Brake Particle Filter Housing With Air-Cooled Disc Encapsulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Brake devices release harmful particles into the air, which are inhaled by people and contribute significantly to air pollution, and existing solutions fail to effectively filter these particles due to the need for air-cooling of brake discs, leading to inadequate protection of the environment and human health.
Innovation Solution
A filter for brake devices that encapsulates the brake device within an inner space, using a cylindrical tubular filtering element and a dismantlable axial fastening system to retain particles, allowing easy replacement or washing of the filtering element, and includes soundproofing and protection against external agents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the brake disc is air-cooled by exposing it to external air flow, then the brake disc can dissipate heat effectively, but harmful particles are released into the air causing pollution
Solution Approach 1:
The brake assembly is segmented into an enclosed brake housing and a separate filtering system. The brake disc remains enclosed within the housing while a dedicated filter element handles particle separation, allowing the cooling function to be maintained through controlled air flow paths that separate particle generation from particle release.
Solution Approach 2:
A filter element is introduced as an intermediary component between the brake disc and the external environment. This filter mediates the air flow, allowing heat dissipation while trapping harmful particles. The filter acts as a barrier that separates the cooling function from the pollution problem.
2Object-generated harmful factors
If the brake disc is fully encapsulated to prevent particle release, then harmful particles are contained, but the brake disc cannot be air-cooled effectively
Solution Approach 1:
The encapsulation is segmented with dedicated air flow paths and a separate filtering section. The brake housing encloses the disc but includes controlled openings for air intake and exhaust, with the filter positioned to intercept particles in the exhaust flow, thus maintaining both containment and cooling.
Solution Approach 2:
The solution moves from a simple enclosed/open dichotomy to a multi-dimensional approach by adding a filtering dimension. The brake assembly is enclosed in one dimension (housing), while air flow is maintained in another dimension (through controlled paths), and particle separation is achieved in a third dimension (via filter media).
3Object-generated harmful factors
If a filter system is added to capture brake particles, then particle pollution is reduced, but the device complexity increases
Solution Approach 1:
The filter element is merged with the existing brake housing structure rather than being a completely separate component. The filter is integrated into the housing walls or end caps, combining the particle filtration function with the structural enclosure, thus reducing overall system complexity.
Solution Approach 2:
The brake housing serves multiple functions: it provides structural support, encloses the brake components, directs air flow for cooling, and houses the filtering element. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity.
4Reliability
If the filtering element is made permanent and integrated, then particle retention is improved, but maintenance and replacement become difficult
Solution Approach 1:
The filtering system is segmented into a removable filter element and a permanent housing structure. The filter element is designed as a separate, extractable component that can be easily removed and replaced without disassembling the entire brake assembly, maintaining both retention reliability and ease of maintenance.
Solution Approach 2:
The filter element is designed with dynamic accessibility - while permanently integrated for reliable particle retention during operation, it can be dynamically removed and replaced when needed. This is achieved through removable fastening mechanisms or snap-fit connections that allow easy access during maintenance.

AI summary
The invention relates to a filter for a brake device, comprising a case (1, 1'), a cylindrical tubular filtering element (2) and a dismantlable axial fastening system. The filtering element (2) is located inside the case (1, 1') and the case (1, 1') includes a cylindrical tubular lateral wall (3) having two opposite end edges, a first and a second. The filtering element (2) sits on an internal surface of the lateral wall (3) of the case (1, 1'). The dismantlable axial fastening system provides axial fastening of the filter when same is assembled in the brake device (F), axial fastening of the filtering element (2) inside the case (1,1'), and means for assembling and dismantling the filter. The purpose of the filter is to collect all the particles harmful to health that are released each time the brake device brakes, preventing said particles from being transferred to the air that is breathed.
