Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple IV bags and pump lines are used to cool multiple ablation devices, then each device can be cooled independently, but the system complexity increases and the risk of leaks and setup errors increases
Solution Approach 1:
The patent combines multiple separate cooling circuits into a single integrated cooling circuit that can service multiple ablation devices simultaneously. This is achieved through a manifold system with a single coolant inlet and outlet that distributes coolant to multiple devices, thereby reducing the number of pump lines and IV bags needed while maintaining independent cooling capability for each device.
Solution Approach 2:
The cooling system is designed with universal components that can accommodate multiple different ablation devices through a standardized manifold interface. The single pump and cooling circuit can serve various device types, reducing the need for device-specific cooling setups and simplifying the overall system while maintaining reliability across different device configurations.
2Adaptability or versatility
If multiple pump lines and containers are used, then each ablation device can be cooled separately, but the number of trailing lines in the theatre increases
Solution Approach 1:
The patent merges multiple separate coolant supply lines into a single integrated cooling circuit with a common pump and manifold system. This consolidation reduces the number of trailing lines in the theatre from multiple separate pump lines to a single unified system, thereby improving ease of operation and theatre setup while maintaining the adaptability to cool multiple different ablation devices through the manifold distribution system.
3Quantity of substance
If a single bag with multiple lines and connectors is used, then the number of containers is reduced, but the risk of leaks and mistakes in setup increases
Solution Approach 1:
The patent segments the cooling system into distinct functional modules: a single coolant container, a pump unit, a manifold with multiple outlets, and individual device connections. This segmentation allows the system to use a single container (reducing quantity) while maintaining reliability through modular design that minimizes the number of connectors and potential leak points compared to a single bag with multiple complex lines.

Function Achieved in This Case
The system simplifies setup, reduces the risk of leaks and errors, and minimizes the number of trailing lines in the theatre, while maintaining efficient coolant circulation and effective cooling of surgical ablation devices.
Implementation Method 1
incorporating a demountable pump head and peristaltic pump tube for efficient coolant circulation
Implementation Method 2
portions of these devices can become hot due to the amount of energy passing through the device... coolant, typically saline or water, circulating through the device has the additional advantage of modulating the dielectric properties of antennas and reducing near field anomalies that can lead to overheating of tissues
