Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional hydraulic connection fittings are used, then the system can be assembled, but the assembly process is complex and time-consuming requiring multiple components and a purge and fill process
Solution Approach 1:
The patent combines multiple functions into a single integrated connector design. The male and female connection elements are designed to work together as a unified system that simultaneously provides sealing, anchoring, and fluid transfer capabilities, eliminating the need for separate sealing elements and reducing the overall component count while maintaining assembly simplicity
Solution Approach 2:
The connector is pre-filled with hydraulic fluid during manufacturing under appropriate conditions. This preliminary action ensures that when the connector is assembled into the hydraulic system, the fluid is already in place, eliminating the need for a complex purge and fill process during assembly, thereby significantly improving assembly speed and productivity
2Ease of operation
If bayonet anchoring systems are used, then quick connection is achieved, but the connection is vulnerable to external stresses and vibrations
Solution Approach 1:
The anchoring system incorporates a threaded nut that can be rotated to progressively tighten and secure the connection. This dynamic adjustment capability allows the connection to be firmly anchored against external stresses and vibrations while still enabling quick assembly and disassembly when needed, balancing ease of operation with reliability
3Reliability
If mechanical valves with resilient springs are used, then sealing is achieved, but the device complexity increases
Solution Approach 1:
The patent extracts and eliminates unnecessary intermediate components from the sealing mechanism. By designing the male and female connection elements to work together as an integrated system with built-in sealing surfaces, the design removes the need for separate mechanical valves and resilient springs, thereby maintaining sealing reliability while significantly reducing device complexity
4Ease of operation
If standard screwed hydraulic unions are used, then connection is achieved, but leakage occurs and pressure resistance is limited
Solution Approach 1:
The connector utilizes composite construction with a crimped sleeve design that combines metal components for structural strength and sealing surfaces for leak-free operation. This composite approach allows the connector to withstand higher pressures and resist leakage better than standard screwed unions while maintaining assembly simplicity through the integrated design
