Engineering Contradiction Analysis
1Measurement precision
If manual inspection of cyclic voltammograms is used, then researchers can hypothesize qualitative mechanisms, but the process is prone to human bias and not compatible with high-throughput screening
Solution Approach 1:
The patent replaces the manual mechanical inspection process with an automated deep learning system. A residual neural network (ResNet) model is trained to analyze cyclic voltammograms and identify electrochemical mechanisms, substituting human researchers' visual inspection with an automated computational approach that eliminates human bias and enables high-throughput screening while maintaining or improving identification accuracy.
2Reliability
If manual inspection with extensive research training is required, then qualitative mechanisms can be hypothesized, but it requires extensive training and may not be compatible with automated testing
Solution Approach 1:
The patent creates a computational copy of the expert analysis process through the ResNet model. The deep learning system is trained on extensive electrochemical data to learn the patterns and features that experts use manually, effectively copying and codifying expert knowledge into an automated algorithm. This allows consistent, reliable analysis without requiring human researchers to have extensive training, while the system complexity is managed through the use of established deep learning architectures.
3Measurement precision
If additional experiments and numerical simulations are applied for quantitative kinetic information, then more accurate kinetic data can be obtained, but the analysis process becomes more time-consuming and complex
Solution Approach 1:
The patent performs preliminary action by training the ResNet model in advance on extensive simulated and experimental data that includes various kinetic parameters. This pre-training allows the model to directly predict mechanisms and kinetic information from new cyclic voltammograms without requiring additional experiments or numerical simulations at the time of analysis. The time-consuming work of learning kinetic relationships is done beforehand, enabling rapid, accurate analysis of new data.
