Engineering Contradiction Analysis
1Manufacturing precision
If physical trial-and-error approaches are used to determine the best arrangement of cooling fluid passages, then manufacturing precision of cooling system can be improved, but manufacturing cost and time consumption increase significantly
Solution Approach 1:
The patent uses computational simulation to create a virtual model of the cooling system, replacing physical prototypes and trial-and-error manufacturing. The simulation allows designers to test different cooling passage arrangements in a digital environment, eliminating the need for costly physical iterations while maintaining design accuracy.
Solution Approach 2:
The patent performs thermal-fluid-structure interaction simulation during the design phase, before actual manufacturing begins. This preliminary computational analysis allows optimization of cooling passage arrangements to be completed virtually, preventing the need for expensive physical trials and errors in the manufacturing process.
2Manufacturing precision
If physical trial-and-error approaches are used to determine the best arrangement of cooling fluid passages, then manufacturing precision of cooling system can be improved, but time consumption increases significantly
Solution Approach 1:
The patent replaces the mechanical trial-and-error manufacturing process with computational simulation. Instead of physically building and testing multiple prototypes, the system uses thermal-fluid-structure interaction simulation to evaluate different cooling passage designs virtually, dramatically reducing design cycle time while maintaining precision.

Solution Approach 1:
The patent integrates thermal-fluid-structure interaction simulation into the existing finite element analysis framework, allowing the cooling system design to be optimized alongside the structural design. This multi-functional approach enables simultaneous optimization of structural and thermal performance without requiring separate complex analysis systems.
Solution Approach 2:
The patent creates a simplified computational model of the cooling system within the FEA software, representing the complex thermal-fluid interactions through validated numerical simulations. This virtual model captures the essential physics without requiring the physical complexity of actual fluid delivery systems during the design phase.

AI summary
Simulation of thermal fluid-structure interaction using bulk flow fluid elements (BFFEs) is described. Each BFFE is configured to include the following characteristics: 1) at least one surrounding layer of solid elements representing either the surrounding structure or the pipe wall; 2) a layer of shell elements or Bulk Node Segments representing the outer boundary of the fluid; 3) a Bulk Node at the center of the BFFE for defining fluid properties (e.g., density, specific heat) and volume (i.e., fluid volume is calculated as the enclosed volume between the Bulk Node and all of the Bulk Node Segments that surround it); 4) a fluid flow beam element or Bulk Node Element for defining fluid flow path to another BFFE; and 5) a contact interface between the solid elements and the shell elements for conducting fluid-structure thermal interaction.
