Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current ventilators use manual monitoring and analysis of measurement signals to identify lack of synchronicity, then ventilation success can be assessed, but the process becomes time-consuming and requires high levels of specialist knowledge and special technical equipment
Solution Approach 1:
The ventilator automatically monitors its own operation by comparing the actual ventilation pressure curve with the target ventilation pressure curve, and automatically detects synchronicity issues without requiring external specialist analysis. The system serves itself by performing self-diagnosis of ventilation performance
Solution Approach 2:
The patent replaces manual mechanical analysis methods with automated electronic signal processing. The monitoring device uses electronic comparison of pressure curves and automated pattern recognition to substitute for manual specialist analysis, eliminating the need for large screens and specialized equipment
2Measurement precision
If current ventilators require specialist staff monitoring and large screens for analyzing measurement signals, then synchronicity can be evaluated, but the system becomes impractical for home ventilation settings
Solution Approach 1:
The patent extracts only the essential information needed for synchronicity evaluation by directly comparing key pressure curve characteristics. Instead of requiring comprehensive signal analysis on large screens, the system extracts and displays only the critical synchronicity indicator, making it suitable for home use
Solution Approach 2:
The system changes the parameter representation from complex measurement signals to a simplified synchronicity indicator that can be easily understood. By transforming the data into a meaningful parameter (synchronicity characteristic), the system makes complex ventilation analysis accessible to non-specialists
3Reliability
If ventilators transfer and evaluate large amounts of data in real-time, then comprehensive ventilation monitoring is achieved, but data transfer requirements become prohibitive for home ventilation
Solution Approach 1:
The system extracts only the essential synchronicity information from the ventilation data by comparing characteristic points of the pressure curves. Instead of transferring and analyzing large amounts of raw data, only the critical synchronicity characteristic is evaluated and transmitted, dramatically reducing data volume requirements
Solution Approach 2:
The ventilator performs preliminary evaluation of the ventilation data locally by comparing pressure curves and determining synchronicity characteristics before any data transfer. This preprocessing eliminates the need to transfer large amounts of raw data, as only the evaluated synchronicity indicator needs to be communicated

AI summary
Disclosed is a ventilator comprising a ventilation device which produces a respiratory gas flow for ventilating at least one patient and sets the respiratory gas flow to at least one ventilation pressure depending on at least one respiratory phase of the patient. Provision is made of a monitoring device which is suitable and configured for monitoring a synchronicity between respiratory phase and target ventilation pressure and, to this end, capturing a characteristic signal for the ventilation pressure and a characteristic signal for the respiratory phase of the patient and comparing the two signals to one another and determining a characteristic for the synchronicity on the basis of the comparison.
