Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual operation of the artificial resuscitator is used, then the device maintains simplicity and portability, but the ventilation volume cannot be effectively controlled

Engineering Contradiction:

Improvesimplicity of operationVSAvoidventilation volume control

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The system automatically controls the exhaust pipe opening and closing based on real-time ventilation volume monitoring. The control module compares current ventilation volume with set values and autonomously actuates the gas control valve, eliminating the need for continuous manual adjustment while maintaining simple operation.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The flow sensor continuously monitors gas flow and provides real-time feedback to the control module. This feedback loop enables the system to adjust the exhaust pipe status dynamically, ensuring precise ventilation volume control without increasing operational complexity for the user.

Inventive Principle:

Principle #23Feedback

2Measurement precision

If automated control is added to control ventilation volume, then ventilation precision is improved, but device complexity increases

Engineering Contradiction:

Improveventilation volume controlVSAvoiddevice structure

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The gas control valve uses pneumatic pressure control to actuate the exhaust pipe opening and closing. The control module regulates gas pressure to the valve, providing automated control functionality while maintaining a relatively simple mechanical structure compared to electronic actuation systems.

Inventive Principle:

Principle #29Pneumatics and hydraulics

Solution Approach 2:

The control module serves as an intermediary between the flow sensor and the gas control valve. It processes the ventilation volume data and translates it into appropriate control signals for the valve, enabling automated control without requiring direct complex integration between sensing and actuation components.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Use of energy by moving object

If the exhaust pipe remains open, then power consumption is reduced, but ventilation volume cannot be controlled

Engineering Contradiction:

Improvepower consumptionVSAvoidventilation volume control

Core Design Contradiction:

Use of energy by moving objectVSMeasurement precision

Solution Approach 1:

The exhaust pipe is opened and closed periodically based on the ventilation cycle and real-time volume monitoring. The control module actuates the gas control valve at appropriate intervals to maintain controlled ventilation while minimizing the time the pipe is closed, thereby reducing power consumption compared to continuously closed configurations.

Inventive Principle:

Principle #19Periodic action
