Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If invasive monitoring methods or specialized equipment like EEG, MEG, or EIT are used, then measurement precision of neurological status is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent replaces complex specialized equipment (EEG, MEG, EIT) with a simplified electromagnetic signal transmission system using standard antennas and spectrum analyzers to measure dielectric properties of brain tissue, achieving neurological monitoring without requiring specialized medical equipment
Solution Approach 2:
The invention measures changes in dielectric properties of brain tissue by analyzing modulated electromagnetic signals at different frequencies, translating complex neurological status into measurable electromagnetic parameter changes that can be detected by standard equipment
2Measurement precision
If invasive monitoring methods are used, then measurement precision is improved, but ease of operation and patient safety deteriorate
Solution Approach 1:
The patent replaces invasive mechanical monitoring methods with non-invasive electromagnetic signal transmission through the skull, eliminating the need for surgical implantation while maintaining the ability to measure brain tissue dielectric properties
Solution Approach 2:
The invention uses electromagnetic waves as an intermediary to transmit information through the skull and brain tissue without direct contact or invasion, allowing measurement of neurological status through the intact skull while avoiding surgical intervention
3Difficulty of detecting and measuring
If current monitoring technologies are used, then specialized measurement capability is improved, but adaptability to various settings deteriorates
Solution Approach 1:
The patent creates a universal monitoring system using standard electromagnetic equipment that can be deployed across multiple settings (emergency rooms, ambulances, nursing facilities) without requiring location-specific specialized equipment, achieving both detection capability and deployment flexibility
4Ease of operation
If non-invasive methods without electrical contact are used, then ease of operation and patient safety are improved, but measurement precision deteriorates
Solution Approach 1:
The invention measures dielectric properties of brain tissue by analyzing frequency-dependent modulation of electromagnetic signals, extracting precise neurological information from non-invasive measurements through mathematical analysis of signal changes
Solution Approach 2:
The patent detects changes in electromagnetic signal characteristics (analogous to color changes in optical detection) as the brain's dielectric properties change due to pathology, translating subtle signal modulations into detectable neurological status indicators
