Hydraulic Block Valve Receptacle Distribution for Compact Brake Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydraulic blocks for slip control systems in vehicle brake systems are not optimized for compactness and efficient component arrangement, leading to potential space inefficiencies and complex interconnections.
Innovation Solution
The hydraulic block design features receptacles for valves and pumps arranged on opposite sides, with an eccentric chamber for pump drive on a separate motor side, allowing for a more compact and space-saving configuration with flexible placement of hydraulic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If all receptacles for solenoid valves are arranged in one cover side of the hydraulic block, then the hydraulic block can be designed with a conventional Cartesian bore arrangement, but the hydraulic block becomes less compact and requires more space for component interconnections
Solution Approach 1:
The patent transitions from arranging all valve receptacles on a single face (2D arrangement) to distributing them across multiple opposite sides of the hydraulic block (3D spatial distribution). This dimensional change allows for more efficient use of internal space and reduces the overall volume required for the hydraulic block while maintaining ease of manufacture through systematic bore arrangement.
Solution Approach 2:
The patent segments the valve receptacles into different groups located on opposite sides of the hydraulic block. This segmentation allows for functional grouping of valves (e.g., inlet valves on one side, outlet valves on the other) and reduces the distance for hydraulic interconnections, thereby reducing the overall volume while keeping the manufacturing process manageable through modular design.
2Volume of moving object
If receptacles for valves are arranged in opposite sides of the hydraulic block, then the hydraulic block becomes more compact with reduced space for interconnections, but the manufacturing complexity increases due to non-Cartesian bore arrangements
Solution Approach 1:
The patent utilizes the third dimension by distributing receptacles across opposite faces of the hydraulic block rather than confining them to a single plane. This spatial distribution reduces the volume required for the hydraulic block while the bore arrangements, though non-Cartesian, are systematically organized to maintain manufacturing feasibility through standardized drilling and tapping procedures.
Solution Approach 2:
The patent applies local quality by optimizing the bore arrangement in specific regions of the hydraulic block. While the overall configuration may be non-Cartesian, each local area (around each receptacle) maintains standardized bore patterns that are easy to manufacture. This allows the design to achieve compactness globally while preserving ease of manufacture locally through region-specific optimization.
3Adaptability or versatility
If connecting bores are provided for brake line connections, then the hydraulic block can be connected to master cylinder and wheel brakes, but the hydraulic block requires additional space for these connecting bores and associated fittings
Solution Approach 1:
The hydraulic block integrates multiple functions including valve receptacles, pump mounting, and brake line connections within a single compact structure. The connecting bores are strategically positioned to serve multiple connection purposes (master cylinder connection, wheel brake connections) while minimizing the space required, thereby achieving high adaptability without increasing volume.
Solution Approach 2:
The patent merges the functions of valve housing, pump mounting, and brake line connection into a single integrated hydraulic block. The connecting bores are combined with the valve receptacle arrangements in such a way that connection points are positioned efficiently within the existing structure, eliminating the need for separate connection components and reducing overall volume while maintaining full connectivity to the brake system.

AI summary
A hydraulic block of a slip control system of a hydraulic vehicle brake system has receptacles for inlet valves and outlet valves of the slip control system arranged on a cover side, and receptacles for block valves, intake valves, and hydraulic accumulator on an opposite main side. All connecting bores for wheel brakes and a main brake cylinder are arranged on a transverse side and an eccentric chamber is arranged on an opposite transverse side of the hydraulic block.
