Engineering Contradiction Analysis
1Productivity
If a depressurization apparatus with nozzles and control units is used to remove carbon dioxide from seawater, then carbon dioxide removal capability is improved, but device complexity and cost increase
Solution Approach 1:
The invention extracts only the essential function of carbon dioxide removal from the complex depressurization system. By using seawater's natural circulation and simple vacuum application, it removes the unnecessary nozzles and control units while retaining the core carbon dioxide removal capability through vacuum-driven bubble formation and separation.
Solution Approach 2:
The system utilizes seawater's own circulation properties and natural vacuum formation to drive the carbon dioxide removal process. The seawater naturally circulates through the vacuum chamber, forms bubbles, and separates carbon dioxide without requiring external nozzles or complex control mechanisms, making the system self-sufficient and simpler.
