Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a multi-part valve body design is used, then assembly flexibility is improved, but device complexity increases and fluid flow is impaired
Solution Approach 1:
The patent merges the valve head, valve stem section, and valve base into a single-piece valve flow body. This integration eliminates the need for separate transverse connections and multiple assembly steps, thereby reducing device complexity while maintaining manufacturing feasibility through optimized flow profile design
2Ease of manufacture
If a multi-part valve body design is used, then assembly flexibility is improved, but fluid flow capacity decreases
Solution Approach 1:
The single-piece valve flow body eliminates interruptions in the fluid flow path that occur with multi-part designs. The integrated structure removes transverse connections and multiple joints, creating an uninterrupted flow profile that significantly improves fluid flow capacity and refueling time
Solution Approach 2:
The valve flow body incorporates optimized curved flow profiles that guide fluid smoothly through the valve assembly. The streamlined geometry reduces turbulence and flow resistance, maximizing fluid flow capacity while maintaining a compact design
3Ease of manufacture
If separate transverse connection elements are used, then assembly flexibility is improved, but the design becomes bulky and refueling time increases
Solution Approach 1:
The patent eliminates separate transverse connection elements by integrating the valve stem section directly into the valve flow body. This removal of unnecessary components reduces the overall assembly size and eliminates flow path interruptions, thereby significantly reducing refueling time
Solution Approach 2:
The invention extracts and removes unnecessary transverse connection elements from the valve assembly. By eliminating these redundant components, the design achieves a more compact structure with improved fluid flow characteristics and reduced refueling time
4Productivity
If a one-piece valve flow body is used, then fluid flow is optimized, but assembly precision requirements increase
Solution Approach 1:
The single-piece construction eliminates multiple assembly interfaces, thereby reducing cumulative tolerance errors and precision requirements. The integrated valve flow body ensures consistent manufacturing quality while optimizing fluid flow through streamlined geometry

AI summary
The invention relates to a dry-coupling receiving part (6) of a dry coupling (100) for fluid, the receiving part comprising: a receiving-part housing (61); a valve device (1) arranged in the receiving-part housing (61) and having a guide seat ring (2) and a valve body (3), around the exterior of which fluid can flow; and a receiving-part control device (5), by means of which the valve body (3) can be moved into a valve opening position (402) and a valve closing position (401). The valve body (3) is radially mounted on the guide seat ring (2) by means of a guide radial bearing (25), such that said valve body can slide axially. The valve body (3) has a valve head (31), a valve base (32) lying outside the guide seat ring (2) and a valve stem part (33) mounted by means of the guide radial bearing (25). The valve body (3) is integrally formed, and the valve head (31), the valve stem part (33) and the valve base (32) form an integral valve flow body (36) with a flow profile that is uninterrupted and as a result unperturbedly uniform. A dry coupling (100) for fluid is formed by the dry-coupling receiving part (6) and a dry-coupling plug-in part (7) connected thereto, the latter comprising a plug-in part valve body (751) of a plug-in part valve (75). The integral valve flow body (36) and the plug-in-part valve body (751) rest against one another in an axially displaceable sliding union which can be brought out of valve closing positions (401, 701), against a restoring force, into valve opening positions (402, 702).
