Modular Leakage Protection Device for Vehicle Brake Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing leakage protection devices for vehicle brake fluid containers are integrated into the containers, making them non-standardizable and requiring entire container replacement upon defect, which is costly and inefficient.
Innovation Solution
A modular leakage protection device that can be attached to fluid containers, featuring a housing with a switching element that can be displaced between open and closed positions, allowing for easy retrofitting and replacement, and designed to prevent fluid leakage during accidents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If leakage protection devices are integrated into the fluid container, then leakage protection function is achieved, but the fluid container cannot be standardized and must be replaced entirely when defective
Solution Approach 1:
The leakage protection device is segmented from the fluid container into two independent components: a detachable housing assembly containing the switching element and sealing mechanism, and the fluid container itself. This segmentation allows the leakage protection function to be attached to or removed from standardized containers, resolving the contradiction between achieving reliable leakage protection and maintaining container standardization.
Solution Approach 2:
The leakage protection device is extracted from the integrated design and made into a separate, removable assembly that can be attached to the fluid container. This extraction enables the container to be standardized while the protection device can be selectively added or removed based on requirements, and allows replacement of only the protection device when defective rather than the entire container.
2Reliability
If leakage protection devices are integrated into the fluid container, then leakage protection is provided, but replacement of defective devices requires replacing the entire container
Solution Approach 1:
By segmenting the leakage protection device into a separate detachable housing assembly from the fluid container, the invention enables independent replacement of the protection device when defective. The housing assembly with switching element can be removed and replaced without affecting the fluid container, significantly improving ease of repair while maintaining leakage protection functionality.
3Reliability
If fluid containers are designed with integrated leakage protection, then leakage protection is achieved, but production costs increase due to non-standardized containers
Solution Approach 1:
The leakage protection function is extracted from the fluid container design, allowing containers to be produced as standardized components without integrated protection mechanisms. The protection device is manufactured separately as a detachable assembly, enabling mass production of standardized containers at lower cost while still providing optional leakage protection through the separately attached housing assembly.

AI summary
The present invention relates to a modular leakage protection device (10) for a fluid container of a vehicle brake system. The modular leakage protection device (10) comprises a housing (12), by means of which the modular leakage protection device (10) can be attached to a fluid discharge opening (508) of the fluid container (500), and a switching element (16), which can be moved between an open position, in which a fluid passage in the housing (12) is released, and a closed position, in which the fluid passage is closed. The switching element (16) is preloaded into the closed position by means of at least one preloading means (14).
