Brake ECU and Hydraulic Assembly Connector Layout for Compact Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electronic brake systems face challenges in minimizing the size of the hydraulic assembly while preventing interference between components.
Innovation Solution
The electronic control unit and hydraulic assembly incorporate two connectors strategically positioned to minimize size and prevent interference, with the first connector disposed above the hydraulic block and the second connector disposed below the reservoir, ensuring efficient component placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If various parts are mounted on the hydraulic block to form a hydraulic assembly, then the functional completeness of the brake system is improved, but the size of the hydraulic assembly increases
Solution Approach 1:
The electronic control unit integrates the control unit, hydraulic block, reservoir, and connectors into a single compact assembly. The control unit is accommodated inside the housing with the hydraulic block mounted on its front surface, merging multiple components into one integrated structure that reduces overall size while maintaining functional completeness.
Solution Approach 2:
The control unit is accommodated inside the housing, and the hydraulic block is mounted on the front surface of the housing. The reservoir is mounted on the side surface of the hydraulic block, creating a nested arrangement where components are placed within or upon each other to minimize space occupation.
2Adaptability or versatility
If two connectors are provided on the housing for electrical connection, then the electrical connectivity is improved, but the complexity of component placement increases
Solution Approach 1:
The first connector is disposed above the position where the hydraulic block is mounted, and the second connector is disposed below the reservoir. This strategic positioning places connectors in locations that do not interfere with other components, simplifying the overall placement complexity while maintaining electrical connectivity.
Solution Approach 2:
The connectors are positioned in different vertical locations (one above the hydraulic block, one below the reservoir) rather than horizontally adjacent to each other. This vertical distribution in different dimensions reduces interference and simplifies routing compared to horizontal placement.
3Volume of stationary object
If the second connector is disposed below the reservoir, then the compactness of the assembly is improved, but the risk of brake fluid leakage into the connector increases
Solution Approach 1:
A brake fluid shield is provided at an upper side of the second connector to prevent brake fluid that may leak from the reservoir from flowing into the second connector. This protective barrier is positioned in advance to counteract the potential harmful effect of fluid leakage.
Solution Approach 2:
The brake fluid shield acts as an intermediary barrier between the reservoir and the second connector. It intercepts and redirects brake fluid flow, preventing direct contact between the fluid and the electrical connector, thus protecting the electrical components.
