Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If ventilation devices only provide ventilation waveforms to users, then the device complexity is reduced, but the ease of operation deteriorates because experienced users must manually analyze waveforms to detect asynchrony, which is not intuitive enough
Solution Approach 1:
The ventilation device automatically detects patient-ventilator asynchrony by analyzing ventilation parameters and autonomously generates visual indicators on the display, eliminating the need for users to manually analyze waveforms. The system serves itself by performing the detection and presentation functions that would otherwise require user expertise and manual interpretation.
Solution Approach 2:
The patent replaces the manual mechanical analysis process (where users visually inspect waveforms and mentally detect asynchrony) with an automated electronic detection system that processes ventilation parameters and generates visual indicators automatically, substituting human cognitive effort with computational analysis.
2Measurement precision
If ventilation devices provide detailed waveform data, then the measurement precision is improved, but the ease of operation deteriorates because the information is not presented in an intuitive manner for non-expert users
Solution Approach 1:
The patent introduces visual indicators (such as markers, symbols, or highlighted regions) as an intermediary layer between the raw waveform data and the user. These indicators automatically highlight periods of asynchrony on the existing waveforms, making the precise detection results intuitively visible without requiring users to interpret complex waveform patterns themselves.
Solution Approach 2:
The patent utilizes color changes or visual property changes in the displayed waveform to indicate detected asynchrony events. By changing the visual appearance (such as color, intensity, or marking) of specific waveform segments, the system maintains measurement precision while making the information immediately recognizable and intuitive for all users regardless of their expertise level.
3Loss of information
If ventilation devices detect and display patient-ventilator asynchrony with detailed information, then the loss of information is reduced, but the device complexity increases due to the need for parameter acquisition and analysis systems
Solution Approach 1:
The patent makes the existing ventilation device perform multiple functions: it continues to provide ventilation control while also acquiring ventilation parameters, detecting asynchrony, and displaying results. By integrating these detection and display functions into the existing ventilator system, the patent reduces information loss without requiring a completely separate complex detection system.
Solution Approach 2:
The patent combines the parameter acquisition, asynchrony detection, and visual display functions into a unified integrated system within the ventilation device. By merging these previously separate functions into one cohesive system, the patent maintains comprehensive information capture while avoiding the complexity of multiple independent systems working together.

AI summary
A ventilation device and a display method therefor. The display method comprises: acquiring parameters of a patient during a ventilation process that are used for representing the occurrence of patient-ventilator asynchrony, wherein the parameters comprise at least one of ventilation parameters of a ventilation device and physiological parameters of a patient; according to the parameters, determining whether patient-ventilator asynchrony occurs; and if patient-ventilator asynchrony occurs, outputting prompt information associated with the patient-ventilator asynchrony, and a parameter waveform generated on the basis of the parameters. The display method is applied to the ventilation device, such that patient-ventilator asynchrony occurring during a ventilation process can be intuitively evaluated, thereby facilitating the creation of ventilation policies by users.
