Brake Hydraulic Filter Layout for Contamination-Free Oil Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hydraulic brakes lack a filter in the hydraulic pressure line connecting the master cylinder and the housing block, allowing foreign materials to move freely and potentially cause malfunctioning braking.
Innovation Solution
A vehicle brake design that includes a filter unit mounted on the block unit to filter oil from the master cylinder, preventing foreign materials from entering the hydraulic circuit unit by using a filter main body with a mesh portion to trap contaminants and a sealing portion to prevent oil leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filter unit is added to filter oil from the master cylinder, then the reliability of the brake system is improved by preventing foreign materials from entering the hydraulic circuit, but the device complexity increases due to the additional filter component and its installation requirements
Solution Approach 1:
The filter unit is installed in advance in the hydraulic pressure line to remove foreign materials before they can enter the hydraulic circuit unit. This preliminary filtering action prevents contamination of the hydraulic system components, thereby improving reliability without requiring complex post-contamination处理 mechanisms
Solution Approach 2:
The filter unit acts as an intermediary component between the master cylinder and the hydraulic circuit unit. It mediates the oil flow by capturing foreign materials generated in the master cylinder before the oil reaches the hydraulic circuit, thus protecting the system while maintaining a relatively simple overall structure
2Reliability
If a filter unit with mesh portion is installed to trap contaminants, then the purity of the hydraulic oil is improved, but the device complexity increases due to the additional filter structure
Solution Approach 1:
The filter unit utilizes a mesh portion made of porous or perforated material that allows hydraulic oil to pass through while trapping foreign materials. This approach achieves effective filtration using a relatively simple porous structure rather than complex multi-stage filtration systems
Solution Approach 2:
The filter unit extracts and removes foreign materials from the hydraulic oil by trapping them in the mesh portion. This extraction of contaminants improves oil purity while the filter itself remains a relatively simple standalone component that can be installed without redesigning the entire hydraulic system
