Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the gas adsorption part is heated under reduced pressure to desorb acid gas, then the acid gas can be captured, but the heating efficiency decreases and energy consumption increases
Solution Approach 1:
The patent changes the pressure parameter from reduced pressure to atmospheric pressure or higher during the desorption heating process. This parameter change improves heating efficiency while maintaining effective acid gas desorption, thereby resolving the contradiction between energy consumption and heating efficiency.
2Quantity of substance
If reduced pressure is applied during desorption to capture acid gas, then the acid gas can be separated, but the heating efficiency of the gas adsorption part decreases
Solution Approach 1:
The patent modifies the pressure parameter during desorption from reduced pressure to atmospheric pressure or higher. This change maintains effective acid gas separation while significantly improving heating efficiency, thus resolving the contradiction between quantity of substance captured and heating efficiency.
3Quantity of substance
If the acid gas adsorption part is heated to desorb acid gas, then the captured gas can be obtained, but the energy required increases under reduced pressure
Solution Approach 1:
The patent changes the pressure condition from reduced pressure to atmospheric pressure or higher during heating. This parameter modification reduces the energy required for desorption while maintaining effective captured gas production, resolving the contradiction between quantity of substance and energy consumption.
