Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If no specialized push device is used, then the surgical procedure is simple, but the organ cannot be transferred to the transplantation site while maintaining optimal temperature conditions
Solution Approach 1:
The device is divided into multiple functional components: an outer bag containing flake ice for cooling, an inner bag to hold the organ, a push assembly with fixing rods and bayonets for positioning, and a seal assembly. Each component serves a specific function, allowing the system to maintain temperature control while transferring the organ through minimally invasive access.
Solution Approach 2:
The organ fixing bag acts as an intermediary device between the organ and the surgical field. It provides a controlled environment for temperature management and facilitates safe transfer through the incision while protecting the organ from direct exposure to body heat.
2Ease of operation
If the organ is transferred without fixation means, then the device is simpler, but the organ cannot be fixed in the optimum location and angle for conduit suturing
Solution Approach 1:
The fixation system uses bayonets that can be rotated and locked into different positions on the fixing rod, allowing dynamic adjustment of the organ's location and angle. The link rod fixing interfaces enable multiple positioning configurations to achieve optimal orientation for conduit suturing.
Solution Approach 2:
The fixing rod with multiple link rod fixing interfaces serves multiple functions: it provides structural support, enables positioning at different angles, and allows secure attachment of the organ fixing bag. This multi-functional design achieves precise positioning without requiring multiple separate devices.
3Reliability
If ice water is not removed after organ rewarming, then the process is simpler, but the organ may be exposed to harmful cold temperatures during reconstruction
Solution Approach 1:
The device incorporates a temperature monitoring system that provides feedback on the organ's temperature status. Based on this feedback, the surgeon can determine when to remove ice water and when the organ has reached the appropriate temperature for reconstruction, ensuring reliable temperature management throughout the procedure.
