Compact Pump Housing with Integrated Valve Rows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle hydraulic assemblies have pump housings that are not compact enough and costly to produce, due to complex designs requiring multiple bores for valve connections and lines.
Innovation Solution
A compact pump housing design with specific arrangements of valve openings and connections, such as direct integration of the pressure sensor into the suction line and use of recesses and blind bores for valve openings, reduces the need for additional bores and simplifies the assembly, allowing for a more compact and cost-effective construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a conventional pump housing design with multiple separate bores for valve connections is used, then all necessary connections can be achieved, but the overall construction becomes less compact and manufacturing costs increase
Solution Approach 1:
The patent combines multiple valve openings (inlet valve openings, outlet valve openings, high-pressure control valve opening, switching valve opening) and their connections into a single integrated pump housing structure. The first through fourth rows of valve openings are arranged in a compact configuration where connecting lines serve multiple functions simultaneously, reducing the total number of separate bores and connections needed in conventional designs.
2Ease of manufacture
If additional bores are formed in the pump housing for pressure sensor connection and valve openings, then all connections can be established, but manufacturing complexity and costs increase
Solution Approach 1:
The pump housing is designed as a multi-functional component where a single integrated structure serves multiple purposes: it provides mounting for pump elements, contains all valve openings (inlet, outlet, control, switching), houses pressure sensor connections, and integrates accumulator and master cylinder connections. This eliminates the need for separate housings or additional specialized bores for each function.
3Volume of moving object
If a compact arrangement of valve openings in four rows is implemented, then space is reduced, but the arrangement complexity increases
Solution Approach 1:
The patent arranges valve openings in a four-row configuration that optimizes spatial utilization. By organizing inlet valve openings in a first row, outlet valve openings in a second row, pressure sensor connection in a third row, and control/switching valve openings in a fourth row, the design creates an efficient vertical stacking arrangement that reduces the overall footprint while maintaining all necessary connection pathways.
