Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users gather at a single location for neurological data collection using standard electrode configurations, then data collection is simplified and standardized, but it becomes cumbersome and expensive, limiting user participation
Solution Approach 1:
The patent creates virtual copies of standard electrode configurations through software-based signal processing. Different physical electrode configurations are mathematically transformed to replicate the electrical fields and signal characteristics of a reference configuration, enabling standardized analysis without requiring identical physical setups
Solution Approach 2:
The system transforms neurological signals by adjusting parameters such as electrode positions, spacing, and configuration geometries through computational methods. This allows signals from diverse physical configurations to be recalibrated to match a standard reference configuration, resolving the contradiction between physical diversity and analytical standardization
2Measurement precision
If users gather at a single location for neurological data collection, then standardized electrode configurations can be used, but it restricts the number of users that participate and may bias the collected neurological data
Solution Approach 1:
The patent develops a universal processing framework that can handle multiple electrode configurations from different manufacturers and applications. The system universally transforms various input configurations into a common analytical format, enabling diverse users and devices to participate without requiring standardized hardware
Solution Approach 2:
The virtual electrode configuration acts as an intermediary layer between diverse physical electrode setups and the analysis pipeline. This intermediate representation standardizes the data without constraining the physical hardware, allowing flexible user participation while maintaining data quality through mathematical normalization
3Adaptability or versatility
If different electrode configurations are used from different manufacturers, then user participation increases and costs decrease, but the neurological signals cannot be directly compared or analyzed together
Solution Approach 1:
The system creates virtual replicas of signals as if they were recorded from a reference electrode configuration. Through computational transformation, signals from any physical configuration are copied into the mathematical space of the reference configuration, enabling direct comparison while preserving the original measurement diversity

AI summary
A system that analyzes neurological signals is described. During operation, the system monitors neurological signals from users at multiple locations, where the neurological signals are associated with different electrode configurations. Then, the system modifies the monitored neurological signals to correct for the different electrode configurations so that a resulting set of modified neurological signals corresponds to a common electrode configuration, thereby facilitating subsequent identification of a subset of the set of modified neurological signals.
