Solution Overview
Problem
Existing brake air purification systems for vehicle brake systems are complex, prone to damage from proximity to brake installations, inefficient due to passive air flow, and difficult to maintain, with integrated designs suffering from high temperatures and limited application dimensions.
Innovation Solution
A brake air through flow and dust collector system is positioned distally from the brake installation, utilizing a combination of a cyclone separator, collecting element, and filter element, with an active air flow generated by a suction element, connected to a negative pressure source, to purify brake air efficiently and maintainably.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the brake air through flow device is positioned in immediate vicinity of the brake assembly, then the purification efficiency is improved, but the device is prone to damage from impacts and dirt
Solution Approach 1:
The patent introduces an air duct as an intermediary component that connects the brake assembly to the brake air through flow device. This intermediary allows the purified air to be delivered close to the brake assembly while keeping the purification device itself at a safe distance, protected from impacts and dirt. The air duct mediates between the need for efficient purification (close proximity) and the need for device protection (distance).
2Reliability
If the brake air through flow device is positioned distally from the brake installation, then the device is protected from impacts and dirt, but the purification efficiency decreases
Solution Approach 1:
The air duct serves as a mediator that extends the reach of the purification device. By positioning the device distally for protection while using the air duct to deliver purified air to the brake assembly, the system maintains both reliability and purification efficiency. The intermediary compensates for the distance gap.
3Device complexity
If a passive air flow system is used, then the system is simpler, but the air flow efficiency is insufficient
Solution Approach 1:
The patent replaces the passive mechanical air flow system with an active pneumatic system using a vacuum generator. This substitution creates negative pressure to actively draw brake air through the purification device, significantly improving air flow efficiency. The mechanical simplicity is maintained through the use of a compact vacuum generator rather than complex mechanical pumps or fans.
Solution Approach 2:
The patent changes the pressure parameter from positive pressure (passive flow) to negative pressure (active vacuum-driven flow). By introducing negative pressure through the vacuum generator, the system achieves much higher air flow efficiency while maintaining relative simplicity. This parameter change transforms the air flow characteristics without adding mechanical complexity.
4Volume of moving object
If an integrated brake dust collector is designed, then the system is compact, but maintenance and serviceability become difficult
Solution Approach 1:
The patent segments the brake air purification system into separate functional components: the brake air through flow device, the air duct, and the vacuum generator. This segmentation allows each component to be independently accessed, inspected, and maintained. The modular design maintains compactness while significantly improving serviceability, as components can be serviced without disassembling the entire brake system.
