Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a simple cooling method or conventional perfusion preservation device is used, then the structure is simple, but the temperature regulation efficiency is insufficient for long-term preservation
Solution Approach 1:
The patent employs a nested container structure where an inner container is placed inside an outer container, creating a fluid flow path between them. This nested design allows the temperature regulating fluid to circulate around the organ container, providing efficient heat exchange while maintaining a relatively simple overall structure. The inner container holds the organ and preservation solution, while the outer container provides the cooling jacket, effectively nesting functional elements to improve temperature regulation without excessive complexity.
Solution Approach 2:
The patent utilizes hydraulic principles by circulating a temperature regulating fluid through the fluid flow path formed between the inner and outer containers. This fluid circulation system enables efficient heat transfer to or from the organ and preservation solution, allowing precise temperature control for extended preservation periods. The inlet and outlet ports facilitate continuous fluid flow, applying hydraulic concepts to achieve effective thermal management.
2Duration of action of moving object
If conventional cold insulation containers are used, then the device structure is simple, but the temperature cannot be maintained appropriately for long hours
Solution Approach 1:
The patent implements continuous temperature regulation by establishing a fluid flow path that allows continuous circulation of temperature regulating fluid between the inlet and outlet. This continuous action enables sustained heat exchange with the organ and preservation solution throughout the preservation period, maintaining appropriate temperatures for extended durations rather than relying on initial cooling alone. The persistent fluid flow ensures ongoing thermal management capability.
3Power
If the fluid flow path is arranged in a spiral shape, then the heat exchange efficiency is improved, but the device complexity increases
Solution Approach 1:
The patent employs a spiral arrangement of the fluid flow path between the inner and outer containers, utilizing curved geometry to maximize the contact surface area between the temperature regulating fluid and the organ container. This spiral configuration allows the fluid to follow a helical path around the inner container, significantly increasing heat exchange efficiency compared to straight-line arrangements, while the spiral form factor integrates naturally into the cylindrical container geometry.

AI summary
An organ container includes a bottomed tubular outer container and a bottomed tubular inner container that is fitted into the outer container. A fluid flow path is formed between an outer peripheral surface of the inner container and an inner peripheral surface of the outer container. The outer container has an inlet that communicates between the fluid flow path and the outside, and an outlet that communicates between the fluid flow path and the outside.
