Pump Housing Valve Bore Arrangement for Compact Brake Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle hydraulic assemblies have pump housings that are not compactly designed and are costly to manufacture, which hinders their efficiency and integration in modern brake systems.
Innovation Solution
The pump housing is redesigned with valve openings and sensor connections arranged in specific rows and lines, utilizing transverse and longitudinal bores to create a more compact and cost-effective structure, allowing for efficient integration of wheel and master cylinder pressure sensors and valves.

Engineering Contradiction Analysis
1Volume of moving object
If the pump housing is designed with traditional bore arrangements for valves and sensor connections, then the housing can accommodate all necessary components, but the overall design becomes less compact and manufacturing costs increase
Solution Approach 1:
The patent combines multiple functional openings (inlet valve openings, outlet valve openings, wheel pressure sensor connections, high pressure switching valve openings, and changeover valve openings) into a unified pump housing structure with systematically arranged bore patterns. This merging of functions into a single integrated housing reduces the overall number of separate components and achieves a more compact design while maintaining manufacturability through standardized bore configurations.
Solution Approach 2:
The pump housing is designed as a multi-functional component that simultaneously accommodates valve assemblies, sensor connections, and fluid pathways through its systematically arranged bore structure. The housing serves multiple purposes: structural support, fluid distribution, sensor mounting, and valve integration, thereby reducing the need for separate housings or mounting structures and achieving compactness without compromising manufacturing ease.
2Volume of moving object
If the pump housing is redesigned with a compact arrangement of openings in systematic rows, then the overall compactness improves, but the complexity of precise bore positioning increases
Solution Approach 1:
The pump housing openings are segmented into systematic rows and columns, with inlet valve openings, outlet valve openings, sensor connections, and switching valve openings each assigned to specific positional patterns. This segmentation into organized arrays simplifies the manufacturing process by providing clear reference frameworks for bore positioning, reducing the actual precision complexity despite achieving compact arrangement.
Solution Approach 2:
The patent organizes openings in three-dimensional space using multiple rows and columns, distributing components along different spatial dimensions rather than concentrating them in a single plane. This dimensional arrangement achieves compactness by efficiently utilizing available space while maintaining accessible positioning for manufacturing operations.

AI summary
A pump housing has at least two inlet valve openings located in a first row, at least two outlet valve openings located in a subsequent second row, and at least one high-pressure switching valve opening and at least one changeover valve opening located in a further subsequent fourth row. At least one connection for a wheel pressure sensor is positioned in a third row between the second and fourth rows. At least one connection for a master cylinder pressure sensor is positioned in a fifth row following the fourth row.
