Hydraulic Valve Housing With Connection Block for Hole Pattern Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydraulic valve systems have complex and heavy valve housings due to standardized hole patterns, making them unsuitable for portable mobile applications, as different hole patterns require different valve housings.
Innovation Solution
A hydraulic valve system with a connection block that translates the valve housing's connection pattern into a pre-defined hole pattern, allowing for easy selection and replacement of the block to accommodate various hole patterns, resulting in a compact and lighter standardized valve housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a standardized valve housing with pre-defined hole patterns is used, then different hole patterns can be accommodated, but the valve housing becomes complex and heavy
Solution Approach 1:
The system is divided into two functional parts: a standardized valve housing and a connection block with hole patterns. The connection block is detached from the valve housing, allowing the housing to remain simple and light while the connection block provides hole pattern adaptability. This segmentation resolves the contradiction by separating the weight-bearing housing from the adaptability-providing connection block.
Solution Approach 2:
The connection block acts as an intermediary between the standardized valve housing and the hydraulic system requirements. It translates between the fixed hole pattern of the housing and the variable connection requirements, enabling adaptability without modifying the housing structure itself.
2Adaptability or versatility
If a complex valve housing is used to accommodate all channels and lines, then all hydraulic connections can be integrated, but the valve housing becomes heavy and unsuitable for portable applications
Solution Approach 1:
The hydraulic connection functions are segmented from the valve housing and consolidated in the connection block. This allows the housing to be minimized to only the essential valve chamber, reducing weight while the connection block provides the necessary connection integration.
Solution Approach 2:
The connection block serves multiple functions: it provides various hole patterns, integrates hydraulic connections, and interfaces with different hydraulic systems. This multi-functionality in a separate component achieves connection integration without adding weight to the housing.
3Adaptability or versatility
If different valve housings are used for different hole patterns, then specific hydraulic requirements can be met, but the overall system complexity and variety of parts increases
Solution Approach 1:
A single standardized valve housing design serves all hole pattern requirements by pairing with different connection blocks. This universal housing design reduces the variety of parts needed, as only the connection blocks need to vary to meet different hydraulic requirements.
Solution Approach 2:
Instead of creating different housing designs for each hole pattern, the solution copies the connection block component with different hole patterns while reusing the same standardized housing design. This reduces complexity by eliminating the need to design and manufacture multiple housing variants.

AI summary
A hydraulic valve system has a valve housing, which has a first connection side and a second connection side. The valve housing has a through-hole for accommodating at least one piston. The valve housing has a third connection side with at least three hydraulic connections which are each connected to the through-hole via a line. The hydraulic valve system has a connection block with at least three hydraulic through-lines each extending from a first connection opening arranged on a housing side of the connection block to at least one second connection opening arranged on a hole pattern side opposite the housing side. Each of the at least three first connection openings is connected in a fluid-tight manner to one of the at least three hydraulic connections, and the second connection openings are arranged in a pre-defined hole pattern. A method for manufacturing a valve housing is also disclosed.
