Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional lung isolation tubes use clamps to close airflow through lumens, then airflow can be controlled, but the device complexity increases and ease of operation decreases
Solution Approach 1:
The patent removes the clamp component entirely from the system. Instead of using a connector set with clamps to close airflow, the invention integrates a control valve directly into the tube assembly that can open and close lumens internally, eliminating the need for external clamps and reducing overall device complexity.
Solution Approach 2:
The control valve is merged with the tube structure, combining the functions of airflow control and tube delivery into a single integrated component. This integration eliminates the need for separate clamp mechanisms and simplifies the overall device architecture.
2Reliability
If conventional lung isolation tubes use complex lumen control valves, then airflow control is achieved, but device complexity increases
Solution Approach 1:
The control valve is designed to be actuated by the user's finger or thumb directly on the tube, eliminating the need for complex external control mechanisms. The valve structure itself provides the control function through simple compression or deformation by the user, making the system self-sufficient and reducing overall complexity.
3Adaptability or versatility
If conventional lung isolation tubes include complex lumen suction ports, then suction functionality is provided, but device complexity increases
Solution Approach 1:
The tube design incorporates suction ports that can function through the same simplified valve mechanism used for airflow control. The control valve serves multiple purposes: regulating airflow to lungs and enabling suction through the same basic structure, reducing the need for separate complex suction control mechanisms.
4Reliability
If conventional lung isolation tubes require connector sets with clamps, then airflow can be closed, but ease of operation in emergencies decreases
Solution Approach 1:
The control valve is pre-positioned and pre-configured within the tube assembly during manufacturing, ready for immediate use. The valve mechanism is designed to be activated instantly by finger pressure without requiring assembly or setup of separate clamp components, enabling rapid deployment in emergency situations.

AI summary
A lung isolation tube assembly includes a control valve that is adapted to be moved between a left lumen position, a right lumen position, and a both lumens position, a connector that is in fluid communication with the control valve and having a port, and a tube that is in fluid communication with the connector. The tube includes a left lumen that is in fluid communication with the connector and a right lumen that is in fluid communication with the connector. The assembly also includes a first cuff that is disposed around a portion of the right lumen and the left lumen and a second cuff that is disposed around the left lumen. The assembly is adapted to convey airflow or oxygen to a human lung via at least one of the left lumen and the right lumen. A method for isolating a human long.
