Engineering Contradiction Analysis
1Loss of time
If manual methods are used to determine common supercell, then flexibility and adaptability are maintained, but the time required increases significantly
Solution Approach 1:
The patent replaces manual mechanical analysis methods with an electronic device-based computational system. The electronic device automatically performs lattice matrix operations, complex plane transformations, and supercell determination algorithms, substituting human manual analysis with automated electronic processing to dramatically reduce determination time.
Solution Approach 2:
The patent transforms lattice matrices from real plane representation to complex plane representation, changing the mathematical parameter space. This transformation enables automated calculation of lattice constant ratios and phase information, allowing the system to efficiently determine common supercells by operating in the complex domain rather than the traditional real domain.
2Productivity
If automated electronic device methods are used, then processing speed increases, but system complexity increases
Solution Approach 1:
The electronic device is designed with universal functionality to handle various lattice structures (cubic, hexagonal, and other crystal systems). The same core processing unit performs complex plane transformations, lattice constant ratio calculations, and supercell determinations for different material systems, reducing overall system complexity through standardized multi-purpose components.
Solution Approach 2:
The patent introduces complex lattice matrices as an intermediary representation between real lattice matrices and final supercell determination. This intermediate complex plane representation simplifies the computational steps required for automated analysis, enabling efficient calculation of lattice constant ratios and phase information while maintaining systematic processing.
3Measurement precision
If complex plane transformation is applied, then automated calculation accuracy improves, but computational complexity increases
Solution Approach 1:
The patent performs preliminary transformation of real lattice matrices into complex lattice matrices before conducting supercell determination. This pre-transformation step establishes the complex plane representation in advance, enabling subsequent automated calculations of lattice constant ratios and phase information to proceed systematically with improved precision while managing computational complexity through structured preprocessing.

AI summary
An electronic device for obtaining common supercell information according to an embodiment of the inventive concept stores first and second lattice matrices, indicative of surface structures of two different materials in a real plane, and a conversion table. The processor retrieves these matrices, obtains complex lattice matrices for both surfaces in a complex plane, and determines a lattice constant ratio from them. Using this ratio, the processor refers to the conversion table to obtain phase information and a conversion matrix. Finally, it calculates common supercell information for both materials based on the lattice constant ratio, phase information, and conversion matrix, and outputs it via the user interface device.
