Solution Overview
Problem
Operators unfamiliar with using defibrillators face challenges in accurately and reliably operating these devices due to inadequate guidance and detection of use states.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the defibrillator provides detailed guidance for unfamiliar operators, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The controller continuously detects the use state of the defibrillator (whether pads are attached, whether analysis is possible) and provides real-time feedback guidance to the operator through the display unit. This dynamic feedback loop allows the system to adapt its guidance based on the current operational state, improving ease of use without requiring overly complex pre-programmed instruction systems.
Solution Approach 2:
The defibrillator automatically detects its own use state and determines what guidance is needed, eliminating the need for external manuals or complex training systems. The device serves itself by monitoring its operational status and providing appropriate instructions, thereby improving ease of operation while maintaining relatively simple device architecture.
2Reliability
If the defibrillator detects use state changes in real-time, then the reliability improves, but the measurement precision requirements increase
Solution Approach 1:
The controller detects whether the pads are attached to the subject before initiating analysis, and determines in advance whether electrocardiogram analysis or impedance analysis should be performed. This preliminary detection approach ensures reliable operation by preventing analysis before proper attachment, while using straightforward detection methods that do not require extremely high measurement precision.
Solution Approach 2:
The system dynamically adjusts its detection and analysis approach based on the detected use state. When pads are attached, it transitions to analysis mode; when not attached, it provides guidance. This dynamic state-based control improves reliability by ensuring proper operational conditions are met, while using adaptive logic rather than continuous high-precision measurement.

Data Source
AI summary
A defibrillator includes a controller configured to detect a use state of a defibrillator by an operator, and output guidance of a use method of the defibrillator, according to the detected use state. The controller is configured to detect a change in the use state in a period before a timing at which a pair of pads of the defibrillator are attached to a skin of a subject from a timing at which the defibrillator is started up.
