Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional diagnostic methods are used for neurological disorders, then the diagnostic process is simple and quick, but the detection precision and reliability are insufficient leading to delayed or misdiagnosis
Solution Approach 1:
The diagnostic system is segmented into multiple specialized sensors (EEG, ECG, EMG, eye tracking, voice analysis) that each capture specific physiological parameters. This segmentation allows each sensor to focus on particular aspects of brain activity, improving detection precision while managing complexity through modular architecture
Solution Approach 2:
The system transitions from single-modality to multi-modal diagnostics by adding temporal, spectral, and spatial dimensions to brain activity analysis. This dimensional expansion enables comprehensive characterization of neurological disorders that cannot be achieved with conventional single-parameter methods
2Adaptability or versatility
If conventional diagnostic methods are used, then the device is simple and portable, but the ability to capture complex multiscale brain activity is insufficient
Solution Approach 1:
The diagnostic system is designed as a universal platform capable of detecting multiple neurological disorders (Alzheimer's, Parkinson's, depression, PTSD, schizophrenia) through integrated multi-modal sensing. This universality allows a single complex system to address diverse clinical needs that would require multiple separate conventional diagnostic tools
Solution Approach 2:
The system integrates heterogeneous sensing modalities (electrical, optical, acoustic, physiological) into a composite diagnostic approach. This composite methodology combines strengths of different sensing technologies to achieve comprehensive brain activity monitoring that exceeds the capability of any single conventional method
3Measurement precision
If invasive tests are used to improve diagnostic accuracy, then the detection precision increases, but the harmful factors and patient discomfort increase
Solution Approach 1:
The system replaces invasive mechanical procedures (surgery, lumbar puncture, biopsy) with non-invasive sensing modalities including EEG electrodes, wearable sensors, eye tracking cameras, and voice analysis. This substitution maintains high detection precision through advanced signal processing while eliminating physical harm associated with invasive tests
Solution Approach 2:
The system uses intermediary sensing technologies that indirectly measure brain activity through physiological proxies (electrical fields, muscle responses, eye movements, vocal patterns). These intermediaries provide accurate neurological information without direct intrusion into brain tissue, reducing patient harm while maintaining diagnostic precision
