Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional diagnostic methods are used for respiratory diseases, then diagnostic accuracy can be achieved through clinical expertise, but the methods require extensive clinical expertise, advanced equipment, and invasive procedures making them inaccessible in underserved areas
Solution Approach 1:
The patent replaces complex mechanical diagnostic equipment with an AI-based audio analysis system. Instead of using advanced respiratory testing equipment that requires specialized facilities, the system uses microphones to record cough and voice sounds, then processes these audio signals through CNN models to detect respiratory conditions. This substitution of mechanical/electronic diagnostic tools with software-based AI analysis resolves the contradiction by maintaining diagnostic capability while eliminating the need for complex equipment.
Solution Approach 2:
The patent creates a virtual model of respiratory disease detection through AI analysis of audio patterns. Rather than requiring physical presence in advanced medical facilities, the system captures audio copies of cough and voice sounds that can be transmitted and analyzed remotely. This copying approach allows diagnostic capabilities to be replicated across multiple devices and locations without requiring each location to have expensive equipment.
2Measurement precision
If traditional diagnostic methods are used, then accurate diagnosis can be obtained, but invasive procedures and extensive clinical expertise are required reducing accessibility
Solution Approach 1:
The patent enables patients to perform self-diagnosis by recording their own cough and voice sounds using mobile devices. The AI system automatically analyzes these recordings and provides diagnostic information without requiring patients to undergo invasive procedures or schedule appointments with specialists. This self-service approach dramatically improves accessibility while maintaining diagnostic accuracy through automated AI analysis.
Solution Approach 2:
The patent introduces an AI-based audio analysis system as an intermediary between patients and healthcare providers. Instead of direct patient-provider interaction requiring clinical expertise, the AI intermediary automatically processes audio recordings and provides diagnostic information. This intermediary layer makes diagnostic services accessible to anyone with a mobile device while preserving diagnostic accuracy through sophisticated AI algorithms.
3Ease of operation
If telemedicine sessions are used for diagnosis, then accessibility is improved, but it becomes difficult to make accurate medical diagnoses based on cough sounds alone
Solution Approach 1:
The patent transforms the diagnostic approach by changing the parameters of audio analysis. Instead of relying on clinicians to interpret subtle auditory cues during telemedicine sessions, the system uses CNN models to automatically extract and analyze multiple acoustic parameters from cough and voice sounds. These parameter transformations include converting audio signals into spectrograms, extracting temporal and spectral features, and generating diagnostic probabilities, thereby maintaining diagnostic accuracy in remote settings.
Solution Approach 2:
The patent adds dimensional depth to telemedicine diagnosis by transforming one-dimensional audio waveforms into two-dimensional spectrograms and multi-dimensional feature vectors. This dimensional transformation allows the AI system to capture complex acoustic patterns that are not apparent in raw audio or to human ears, enabling accurate remote diagnosis without requiring clinicians to interpret subtle sound variations during telemedicine sessions.
4Measurement precision
If more advanced equipment and expertise are deployed, then diagnostic accuracy improves, but healthcare costs increase
Solution Approach 1:
The patent replaces expensive, permanent diagnostic equipment with inexpensive, software-based AI analysis that runs on common mobile devices. Instead of investing in costly respiratory testing equipment that requires specialized facilities, the system uses freely available or low-cost smartphone microphones and processors to perform sophisticated diagnostic analysis. This approach dramatically reduces healthcare costs while maintaining diagnostic accuracy through the power of AI algorithms.
Solution Approach 2:
The patent creates a universal diagnostic platform that can be deployed across multiple devices and settings without requiring specialized equipment. The same AI model can analyze cough and voice sounds from any mobile device, making the diagnostic capability universally accessible. This multi-functionality eliminates the need for each healthcare facility to invest in expensive specialized equipment, thereby reducing overall healthcare costs while maintaining consistent diagnostic accuracy across different locations.
Data Source
AI summary
A method and system for biomarker detection of cough and voice sounds using artificial analysis (AI) with a Convolutional Neural Network (CNN). Audio recordings of coughs and voice sounds are collected from a patient either in-person or remotely via telemedicine or telehealth platforms. The collected audio signals are transformed into waveform graphs and spectrograms for distinct processing pathways. AI CNN methods are used to classified cough types and detect respiratory diseases based on non-invasive acoustic signals. A final diagnostic report is prepared including one or more cough types and one or more disease categories and the calibrated probabilities for the patient. By analyzing the unique sound characteristics of coughs underlying respiratory conditions are accurately identified in real-time, offering a cost-effective and scalable diagnostic tool.
