Hydraulic Block Port Layout for Compact Brake Line Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydraulic block designs for slip-controlled external power vehicle brake systems face challenges in accommodating brake lines and electronic components within the limited space of a motor vehicle's engine compartment without requiring significant modifications, and in efficiently connecting brake lines from wheel brakes to the hydraulic block.
Innovation Solution
A cuboid-shaped hydraulic block with a master brake cylinder bore and external power cylinder bore, featuring connections for wheel brakes arranged on or near the large sides and long sides, allowing for compact installation in the engine compartment and easy connection of brake lines, along with an electronic control unit that can be integrated with the vehicle's electrical system with minimal modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If connections for wheel brakes are arranged on large sides of the hydraulic block, then ease of connection with brake lines is improved, but device complexity increases due to spatial arrangement requirements
Solution Approach 1:
The patent applies dimensionality change by arranging connections for wheel brakes not only on large sides but also on long sides of the cuboid hydraulic block. This multi-faceted spatial distribution optimizes brake line routing in the engine compartment while maintaining a compact overall structure, resolving the contradiction between ease of connection and device complexity.
2Adaptability or versatility
If the hydraulic block is designed with multiple bores and connections for slip control system, then functionality is improved, but manufacturing complexity increases
Solution Approach 1:
The hydraulic block is designed as a multi-functional component that integrates the master brake cylinder bore, external power cylinder bore, connections for wheel brakes, and receptacles for solenoid valves and other hydraulic components. This universal design consolidates multiple functions into a single component, improving adaptability while managing manufacturing complexity through standardized construction.
Solution Approach 2:
The hydraulic block features segmented functional zones with distinct bores and connections for different subsystems (master brake cylinder, external power cylinder, wheel brake connections, solenoid valve receptacles). This segmentation allows independent installation and maintenance of each subsystem while maintaining overall system integration, balancing functionality with manufacturability.
3Volume of moving object
If the hydraulic block accommodates all hydraulic components within a compact size, then space utilization is improved, but ease of installation decreases
Solution Approach 1:
The master brake cylinder and external power cylinder are installed within bores of the hydraulic block, creating a nested arrangement where components are housed within the block structure. This nesting approach maximizes space utilization by eliminating separate mounting structures while maintaining ease of installation through standardized bore dimensions and assembly procedures.
