Engineering Contradiction Analysis
1Reliability
If real components are used in magnetic resonance tomography systems, then the system provides accurate diagnostic imaging functionality, but the research and development costs and time expenditure increase significantly
Solution Approach 1:
The patent creates a digital twin that is a virtual copy of the magnetic resonance tomography system, including virtual models of all physical components such as the magnet, gradient coils, and RF systems. This digital replica allows researchers to simulate and analyze system behavior without requiring physical hardware, thereby reducing R&D costs and complexity while maintaining functional accuracy for diagnostic imaging evaluation
Solution Approach 2:
The patent replaces the physical mechanical and electromagnetic system with a computer-based simulation system. The digital twin uses software models to replicate the electromagnetic fields, signal processing, and image reconstruction algorithms, substituting physical components with computational equivalents that eliminate the need for expensive hardware modifications and prototypes
2Manufacturing precision
If prototypes are produced for testing and development, then system improvements can be evaluated, but the production time and costs increase non-negligibly
Solution Approach 1:
The patent implements preliminary testing and evaluation within the digital twin environment before any physical prototype production. Researchers can perform virtual experiments, adjust parameters, and validate design changes in the simulation, ensuring that only optimized designs are eventually built physically. This preliminary action in the digital domain eliminates repeated prototype iterations and significantly reduces production time
Solution Approach 2:
By creating a faithful digital replica of the tomography system, the patent enables virtual prototyping where design variations can be tested without physical manufacturing. The digital twin preserves all interface transitions and signal exchanges, allowing comprehensive performance evaluation of different configurations without the time and cost of producing physical prototypes
3Device complexity
If simulations are created for individual subcomponents, then development costs are reduced, but maintaining existing interfaces between subcomponents becomes challenging
Solution Approach 1:
The patent designs the digital twin with universal interface standards that replicate the actual hardware interfaces between subcomponents. The virtual models of the magnet, gradient system, RF components, and image reconstruction modules all communicate through standardized data protocols and interface definitions, ensuring that the simulation maintains the same adaptability and interface compatibility as the physical system while enabling cost-effective virtual development
