Actuator Arrangement with Integrated Valve Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing actuator arrangements for fluid-driven rotational movements face challenges in achieving a compact design and simplified fluid stream provision.
Innovation Solution
The actuator arrangement incorporates a valve housing with a circular ring section profiling, where the valve housing is directly connected to the actuator housing, featuring a concave and convex profiled wall sections, and includes a valve module with a fluid-tight design, allowing for efficient fluid management and compact integration with the actuator housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the valve housing is directly connected to the actuator housing with a compact design, then the installation space is reduced and the system becomes more compact, but the fluid connection and valve module integration become more complex
Solution Approach 1:
The valve housing is directly connected to the actuator housing, merging two previously separate components into an integrated assembly. This reduces the overall installation space while maintaining functional independence through internal fluid channels and modular valve module design.
Solution Approach 2:
The valve module is accommodated within the valve housing, creating a nested structure where the valve module (inner component) is housed within the valve housing (outer component). This nested arrangement optimizes space utilization while keeping the fluid connection paths internal and organized.
2Reliability
If the valve housing is extended with a circular ring section profiling, then the structural integrity and fluid distribution are improved, but the manufacturing complexity increases
Solution Approach 1:
The valve housing is extended with a circular ring section profiling, replacing straight cylindrical sections with curved geometries. This circular extension improves structural integrity and facilitates radial fluid distribution, while the standardized circular profile allows for efficient manufacturing processes.
3Measurement precision
If the valve module is fluid-tightly accommodated in the valve shaft, then the fluid control precision is improved, but the assembly and disassembly difficulty increases
Solution Approach 1:
The valve arrangement is segmented into modular components: the valve module, the valve shaft, and the valve housing. The valve module can be independently assembled into and disassembled from the valve shaft, allowing for maintenance and replacement without dismantling the entire actuator system.
Solution Approach 2:
The valve shaft acts as an intermediary component between the valve module and the valve housing. It provides a standardized interface that accommodates the valve module with fluid-tight sealing, simplifying the assembly process while maintaining precise fluid control.
