Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a universal heart port device with multiple adapter coupling flanges is used, then adaptability for different intracardiac procedures is improved, but device complexity increases
Solution Approach 1:
The heart port body is designed with multiple adapter coupling flanges (first, second, and third flanges) that can accommodate different types of adapters for various intracardiac procedures including LVAD implantation, canula placement, and plug insertion. This multi-functional design allows a single heart port device to serve multiple therapeutic purposes, resolving the contradiction by providing adaptability without requiring multiple separate devices.
Solution Approach 2:
The device is segmented into distinct functional components: the heart port body, multiple adapter coupling flanges, suture ring support flanges, and various interchangeable adapters (LVAD adapter, canula adapter, plug). This segmentation allows each component to be optimized for its specific function while maintaining overall system adaptability, managing complexity through modular design.
2Reliability
If suture ring support flanges are added to secure the heart port, then reliability of attachment is improved, but device complexity increases
Solution Approach 1:
The suture ring support flanges are pre-integrated into the heart port body structure, positioned to receive and secure sutures during the implantation procedure. This preliminary preparation ensures reliable attachment to the heart tissue without requiring additional separate securing components, thereby improving reliability while minimizing the increase in device complexity.
3Ease of operation
If multiple adapter coupling flanges are implemented, then ease of operation for different procedures is improved, but device complexity increases
Solution Approach 1:
The multiple adapter coupling flanges are designed with consistent geometry and positioning relationships, allowing different adapters to be coupled to the same heart port body through a standardized interface. This universality simplifies the operation of switching between different intracardiac procedures, as the basic coupling mechanism remains the same even though different adapters are used.

AI summary
A universal heart port, in various embodiments, comprises: a cylindrical heart port body defining a circular top surface, an outer surface, and a cylindrical opening that extends through the heart port body; and one or more adapter coupling flanges, each respective adapter coupling flange of the one or more adapter coupling flanges extending radially outward along at least a portion of the top surface of the heart port body and comprising a respective end stop portion that extends perpendicularly downward from a respective end portion of the respective adapter coupling flange. In some embodiments, each of the adapter coupling flanges are substantially evenly spaced about the outer surface of the heart port body. In some embodiments, the heart port further comprises one or more adapters configured for selective coupling to the heart port. The adapters may include a plug, a canula adapter, an LVAD adapter, etc.
