Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a gas cylinder is used to supply medical gas to the ventilator, then the ventilator can provide appropriate oxygen to patients, but the ventilator cannot be easily moved and the component ratio of medical gas cannot be adjusted
Solution Approach 1:
The patent replaces the mechanical gas cylinder system with an electrolytic gas generation system that uses electrical energy to produce medical gases on-demand. The electrolytic device generates oxygen and hydrogen through water electrolysis, eliminating the need for heavy gas cylinders and manual gas ratio adjustments, thereby improving both reliability and ease of operation
Solution Approach 2:
The electrolytic gas generation device enables the ventilator to produce its own medical gases through water electrolysis, making the system self-sufficient. The control unit automatically adjusts the electrolysis parameters to maintain appropriate gas component ratios, eliminating the need for external gas cylinder replacements or manual interventions
2Adaptability or versatility
If multiple gas cylinders are combined to adjust medical gas component ratios, then different gas compositions can be achieved, but the system becomes complex and requires frequent replacement or combination of cylinders
Solution Approach 1:
The patent changes the operating parameters of the electrolytic gas generation device (electrolysis voltage, current, time) to adjust the component ratios of medical gases. By controlling the electrolysis process parameters, the system can generate oxygen, hydrogen, or their mixtures in various ratios without requiring multiple gas cylinders or complex combination operations
