Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If statistical calculations are used to predict neural speech encoding disorders, then the prediction can be performed, but the precision and reliability of the prediction deteriorates
Solution Approach 1:
The patent replaces traditional statistical calculation methods with machine learning algorithms that automatically analyze EEG signal features. This substitution transforms the prediction system from manual statistical analysis to an automated computational model, significantly improving prediction precision while managing complexity through algorithmic automation.
Solution Approach 2:
The patent changes the parameters used for prediction from simple statistical metrics to comprehensive EEG signal features including frequency spectrum, time-frequency representation, and neural oscillation patterns. By expanding and transforming the parameter set, the system achieves higher prediction accuracy in identifying neural speech encoding disorders.
2Reliability
If EEG signals are analyzed using machine learning algorithms, then the prediction precision improves, but the complexity of the system increases
Solution Approach 1:
The patent segments the complex prediction task into distinct processing stages: EEG signal acquisition, feature extraction (frequency spectrum, time-frequency analysis), machine learning model processing, and risk prediction output. This segmentation makes the complex system more manageable and interpretable while maintaining high reliability through specialized processing at each stage.
Solution Approach 2:
The patent introduces intermediate feature extraction steps that transform raw EEG signals into meaningful representations before feeding them to the machine learning algorithm. These intermediaries (signal preprocessing, feature engineering) act as mediators that bridge the gap between complex biological signals and the prediction model, improving reliability while structuring the system complexity in a hierarchical manner.
3Loss of time
If early EEG signals from infants aged 0 to 6 months are used for prediction, then early detection is enabled, but the difficulty of detecting and measuring increases due to signal variability
Solution Approach 1:
The patent performs preliminary analysis of EEG signal characteristics specific to infants aged 0-6 months before applying the prediction model. By pre-processing and adapting the analysis methodology to account for developmental variability in this age group, the system enables early detection while mitigating measurement difficulties through age-appropriate signal processing protocols.
Solution Approach 2:
The patent adjusts measurement parameters and feature extraction methods to accommodate the unique characteristics of infant EEG signals, including higher signal variability and developmental changes. By dynamically adapting parameters based on infant age and signal characteristics, the system achieves reliable early detection despite the inherent measurement challenges.
