Brake Fluid Collection Device with Gas-Liquid Separation Tank
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brake fluid collection and supply systems are complex and large due to multiple tanks and lines, which complicates the process of gas-liquid separation and can lead to air or moisture entry into the brake system, affecting brake performance.
Innovation Solution
A compact brake fluid collection and supply device with a gas-liquid separation tank sectioned into a lower and upper chamber, along with a sub-tank, performs gas-liquid separation through counterflow mechanisms in three stages, using negative pressure to prevent atmospheric contact and enhance separation efficiency, allowing for a simplified structure and effective removal of gases and moisture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple tanks and lines are used for brake fluid collection and supply, then gas-liquid separation can be performed, but the structure becomes complicated and large
Solution Approach 1:
The patent combines multiple tanks (collection tank, storage tank, separation tank) and multiple lines into a single integrated brake fluid collection and supply device. The collection tank serves dual purposes as both collection and separation chamber, eliminating the need for separate dedicated tanks for each function. This merging reduces the overall component count and structural complexity while maintaining effective gas-liquid separation capability.
Solution Approach 2:
The collection tank is designed to perform multiple functions simultaneously: it acts as a collection tank for receiving brake fluid from the brake system, a separation tank for gas-liquid separation, and a storage tank for holding processed brake fluid. This multi-functionality eliminates the need for separate dedicated tanks for each operation, simplifying the overall device structure.
2Reliability
If multiple tanks and lines are used for brake fluid collection and supply, then gas-liquid separation can be performed, but the device size increases
Solution Approach 1:
The patent merges multiple functional tanks into a single integrated collection tank that performs collection, storage, and separation functions. This consolidation significantly reduces the total volume occupied by multiple separate tanks and connecting lines, making the device more compact while maintaining separation effectiveness.
Solution Approach 2:
The device employs a nested structure where the section wall with opening is positioned within the collection tank, creating internal chambers for different functions. The sub-tank is nested within the overall device structure, allowing efficient use of space and reducing the external dimensions of the device while maintaining internal separation functionality.
3Reliability
If brake fluid is collected and processed through multiple components, then gas removal can be achieved, but air or moisture may enter the brake system
Solution Approach 1:
The patent creates a closed, controlled environment within the collection tank where brake fluid is processed. The section wall with opening and sub-tank structure maintains a sealed system that prevents atmospheric air and moisture from entering the brake fluid during collection and separation operations, eliminating the harmful effects of contamination.
Solution Approach 2:
The section wall with opening acts as an intermediary structure that facilitates gas-liquid separation while maintaining system sealing. The sub-tank serves as an intermediate chamber that receives and processes brake fluid, preventing direct exposure to atmospheric conditions and blocking the entry path for air and moisture contaminants.

Implementation Method 1
gas-liquid separation is performed by circulating the brake fluid in the lower chamber through a circulation line where the brake fluid is discharged from the lower chamber and returned to the lower chamber
Implementation Method 2
a gas-liquid separation tank sectioned into a lower chamber and an upper chamber by a section wall including an opening
Implementation Method 3
using negative pressure to prevent atmospheric contact and enhance separation efficiency

AI summary
This device for collecting and supplying brake fluid has a gas-liquid separation tank divided into a lower chamber and an upper chamber with a partition wall interposed therebetween. Connected to the gas-liquid separation tank are: a collection line for collecting brake fluid from the brake system of a vehicle in the gas-liquid separation tank; a circulation line for extraction of brake fluid from the lower chamber and the return thereof to the lower chamber; and a replenishment line for replenishing the gas-liquid separation tank with fresh brake fluid. Air intake for the brake system is performed via a main intake line, and air intake for the gas-liquid separation tank is performed via an auxiliary intake line. Both the main intake line and auxiliary intake line are connected to an auxiliary tank.
