Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual coordination methods are used to manage CPR compressions and ventilation, then medical staff can control the process, but precise and stable control for long periods becomes difficult and reduces practicality
Solution Approach 1:
The ventilator system automatically detects compression phase and frequency, then autonomously determines and executes ventilation timing without continuous human intervention. The system serves itself by using its own sensors and processors to monitor CPR parameters and trigger ventilation automatically, eliminating the need for manual coordination while maintaining precise and stable control over extended periods.
2Ease of operation
If communication protocols between compression equipment and ventilators are used, then coordination between devices is achieved, but automatic coordination capability is lost and manual management is required
Solution Approach 1:
The ventilator system integrates multiple functions into a single unified device: it combines compression detection capabilities, phase analysis algorithms, and ventilation control mechanisms. By merging these previously separate functions (compression monitoring, timing calculation, and ventilation execution) into one integrated system, the invention achieves automatic coordination without requiring complex communication protocols between multiple devices.
3Stability of the object's composition
If mechanical compression equipment is used instead of manual compressions, then consistent compression delivery is improved, but coordination with ventilation becomes more complex
Solution Approach 1:
The ventilator system continuously monitors compression parameters (phase and frequency) through integrated sensors and uses this real-time feedback to automatically adjust ventilation timing. The system processes compression signals, identifies compression phase and frequency dynamically, and uses this feedback information to trigger ventilation at the optimal moment, achieving seamless coordination between mechanical compression and ventilation without complex external control mechanisms.
