Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If dedicated hardware devices are used for detecting specific pathologies, then detection precision for that pathology is improved, but device versatility and adaptability to other pathologies deteriorates

Engineering Contradiction:
Improvepathology detection precisionVSAvoidpathology detection versatility
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent applies universality by designing a single ear-worn device with microphone arrays that can detect multiple types of pathologies (OSA, COPD, asthma, pneumonia, COVID-19, tuberculosis, meningitis, encephalitis, stroke, heart attack, cancer) rather than requiring separate dedicated devices for each condition. The device uses universal acoustic sensing capabilities combined with machine learning algorithms to identify different pathology patterns.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent utilizes parameter changes by transforming raw acoustic signals into processed features through machine learning models. The system detects different pathologies by analyzing changes in acoustic parameters (frequency, amplitude, temporal patterns) and uses machine learning to interpret these parameter variations as indicators of different disease states.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 1:

The patent reduces cost and improves accessibility by creating a single multi-functional ear-worn device that replaces the need for multiple expensive dedicated devices. The universal design allows one device to serve multiple detection functions, making the technology more affordable and accessible to patients and healthcare systems.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent applies copying by using machine learning models that can replicate and recognize pathology patterns from acoustic signals. The trained models enable the device to accurately detect various pathologies without requiring complex hardware for each specific condition, thereby reducing overall system cost.

Inventive Principle:

Core Design Contradiction:
Duration of action of stationary objectVSDevice complexity

Solution Approach 1:

The patent extracts the essential monitoring function from complex conventional systems by using a simple ear-worn device with microphone arrays. The device captures acoustic signals that naturally occur during breathing and sleeping, eliminating the need for complex sensors, actuators, and multiple subsystems required by traditional monitoring equipment.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces complex mechanical monitoring systems with acoustic field-based detection. Instead of using mechanical sensors to directly measure physiological parameters, the system uses acoustic microphones to capture sound waves and processes these signals through machine learning algorithms to identify pathologies, thereby simplifying the overall system architecture.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
