Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connector system uses multiple separate elements (nut, main body, screw aid) to secure the catheter, then the connection reliability is improved, but the device complexity and ease of operation deteriorate
Solution Approach 1:
The patent merges the nut and main body into a single integrated connector element, eliminating the need for separate components. This integration maintains the securing function while reducing complexity and improving ease of operation, directly resolving the contradiction between connection reliability and device complexity
2Reliability
If a connector system uses multiple separate elements with screwing operations, then the connection reliability is improved, but the ease of operation deteriorates
Solution Approach 1:
By combining the nut and main body into one piece, the patent eliminates multiple screwing and unscrewing operations. The integrated design allows for simpler attachment and detachment procedures while maintaining secure connection, thereby improving ease of operation without sacrificing reliability
3Stability of the object's composition
If the fixing means clamps the catheter between the tubular pin and fixing means, then the connection stability is improved, but the distance required for clamping increases
Solution Approach 1:
The fixing means is designed to clamp the catheter in a compact configuration where the catheter is nested between the tubular pin and the fixing means structure. This nesting arrangement achieves stable connection while minimizing the overall clamping distance, resolving the contradiction between connection stability and clamping length

Function Achieved in This Case
The connector system simplifies the handling and secure attachment of catheters to fluid transfer systems, ensuring reliable fluid flow while minimizing the distance required for clamping, thus enhancing user convenience and connection stability.
Implementation Method 1
the fixing means in the fixing position may be adapted to clamp the end portion of the catheter between the tubular pin and the fixing means, wherein the clamping force acts substantially transverse to the fluid flow direction
