Master Brake Cylinder Filter Element for Dirt Particle Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dirt particles present in the fluid reservoir of a master brake cylinder assembly can mix with brake fluid and distribute throughout the motor vehicle brake system, causing functional impairment and operational issues, necessitating complex cleaning processes and increased manufacturing costs.
Innovation Solution
A filter element is integrated within the master brake cylinder assembly, specifically designed to collect dirt particles as the brake fluid flows between the fluid reservoir and the master brake cylinder, eliminating the need for pre-cleaning the reservoir and reducing manufacturing complexity and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If complicated cleaning processes are implemented to remove dirt particles from the fluid reservoir, then the purity of brake fluid is improved, but the device complexity and manufacturing costs increase
Solution Approach 1:
The filter element is pre-installed in the master brake cylinder before assembly with the fluid reservoir. This preliminary placement ensures that the filtering function is already in position to capture dirt particles as soon as brake fluid flows through the system, eliminating the need for complex post-assembly cleaning processes while maintaining brake fluid purity
Solution Approach 2:
The filter element acts as an intermediary component between the fluid reservoir and the master brake cylinder's pressure-generating components. It intercepts dirt particles in the brake fluid before they can reach and impair other components, providing a simple yet effective solution that avoids complex cleaning requirements
2Manufacturing precision
If the fluid reservoir is cleaned thoroughly before assembly, then dirt particles are removed, but the manufacturing time and costs increase
Solution Approach 1:
The filter element enables the brake system to self-clean by capturing dirt particles as brake fluid naturally circulates through the system during normal operation. This eliminates the need for time-consuming manual cleaning processes before assembly, as the filter performs the purification function automatically once the system is in service
Solution Approach 2:
The filter element is designed to collect and retain dirt particles that would otherwise contaminate the brake system. By concentrating impurities in one location (the filter), the system maintains clean brake fluid without requiring extensive cleaning procedures during manufacturing, thus reducing manufacturing time while ensuring purity
3Object-affected harmful factors
If sieve arrangements are used in filling openings, then ingress of dirt particles from environment is prevented, but dirt particles already present in the reservoir cannot be removed
Solution Approach 1:
The filter element is strategically positioned within the master brake cylinder to extract and remove dirt particles that are already present in the brake fluid within the closed system. This internal filtering approach complements external sieve arrangements by addressing contaminants that originate inside the system rather than from environmental ingress
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 filter element effectively captures dirt particles during system operation, preventing their distribution in the brake fluid circuit, ensuring consistent system response and reducing manufacturing outlay and costs by allowing dirt particles to be addressed in situ, rather than requiring a completely clean reservoir before assembly.
Implementation Method 1
at least one filter element is arranged within the master brake cylinder assembly in such a way that a brake fluid volume exchanged between master brake cylinder and fluid reservoir during operation flows through the filter element, wherein the filter element is designed to collect dirt particles present in the brake fluid
