Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent replaces subjective mechanical assessment methods with objective automated detection using biosignal acquisition units that measure physiological parameters (respiratory rate, heartbeat rate) through sensors. This substitution eliminates human subjectivity while maintaining ease of operation through automated data collection and processing.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-monitoring where patients can independently track their own physiological parameters and receive automated alerts when thresholds are exceeded. The detection apparatus operates autonomously without requiring medical professionals for continuous monitoring, improving both ease of operation and detection accuracy.

Inventive Principle:

Principle #25Self-service

2Measurement precision

If cumulative parameter comparison is implemented, then measurement precision is improved, but device complexity increases

Engineering Contradiction:

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system pre-sets determination thresholds for physiological parameters based on normal ranges. These thresholds are established in advance, allowing the complex cumulative comparison logic to be simplified into straightforward threshold checking during operation. This preliminary preparation reduces real-time computational complexity while maintaining high detection accuracy.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The apparatus continuously monitors physiological parameters and provides feedback by comparing current values against predetermined thresholds. This feedback mechanism enables simple threshold-based detection rather than complex real-time analysis, reducing system complexity while maintaining precision through continuous automated comparison.

Solution Approach 1:

The biosignal acquisition unit operates continuously to monitor physiological parameters without interruption. This continuous monitoring eliminates detection delays by ensuring that parameter changes are captured immediately, reducing time loss while maintaining high measurement precision through uninterrupted data collection.

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The system implements real-time feedback by continuously comparing measured physiological parameters against predetermined thresholds and immediately triggering alerts when abnormalities are detected. This rapid feedback loop minimizes response time while maintaining accuracy through automated continuous comparison.

AI summary

A detection apparatus includes a biosignal acquisition unit configured to acquire a biosignal of a user, and a controller. The controller is configured to calculate one or more parameter values related to breathing of the user based on the biosignal acquired from the biosignal acquisition unit, and detect a presence of a symptom of aggravation of cardiac failure in the user when a calculated parameter value in which a cumulative value of previous day difference data has exceeded a predetermined threshold is present, among the calculated parameter values.
