Hydraulic Brake Assembly Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hydraulic brake systems require more installation space due to the arrangement of components like the fluid container, electronic control unit, and brake pressure control device, which hinders efficiency and increases production costs.
Innovation Solution
A compact assembly for hydraulic brake systems where a fluid container is coupled leaktight to a hydraulic block using a fastening device with a one-piece connecting element, allowing the fluid container and electronic control unit to be attached to the hydraulic block in a single assembly step, reducing installation space and production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the fluid container, electronic control unit, and brake pressure control device are arranged separately under the engine hood, then each component can be independently manufactured and maintained, but the total installation space required increases and production costs rise
Solution Approach 1:
The patent combines the fluid container, electronic control unit, and brake pressure control device into a single integrated assembly that mounts to the brake master cylinder. This merging of previously separate components reduces the total installation space under the engine hood while maintaining independent functionality of each component through modular design within the integrated structure.
2Productivity
If multiple components are assembled separately and then installed, then each component can be manufactured independently, but the assembly process becomes time-consuming and production costs increase
Solution Approach 1:
The fluid container is pre-assembled with the brake master cylinder, and the electronic control unit is pre-mounted on the brake pressure control device before final installation. This preliminary assembly of sub-components streamlines the overall assembly process, reducing installation time and production costs while maintaining the ability to manufacture each sub-component independently.
3Area of stationary object
If the fluid container is mounted separately from the brake master cylinder, then the container can be serviced independently, but the assembly requires more installation space and additional mounting components
Solution Approach 1:
The integrated assembly is designed with modular segments where the fluid container, brake master cylinder, and electronic control unit can be independently accessed and serviced. The segmentation allows each component to be maintained separately while maintaining a compact integrated structure that reduces overall installation space requirements.
