Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional sorption module design is used, then the structure is simple, but the airflow guidance is ineffective and carbon dioxide adsorption efficiency is low
Solution Approach 1:
The process chamber is divided into multiple compartments by support frames, with each compartment containing sorption elements. This segmentation improves airflow guidance and carbon dioxide adsorption efficiency while maintaining a manageable structural complexity through modular design.
2Productivity
If the residence time of ambient air is extended, then carbon dioxide adsorption efficiency is improved, but the process chamber volume increases
Solution Approach 1:
Sorption elements are arranged in multiple layers within the process chamber, utilizing the vertical dimension to extend the residence time of ambient air. This multi-layer arrangement increases adsorption efficiency without proportionally increasing the overall chamber volume.
3Productivity
If heating elements are added for desorption, then carbon dioxide release efficiency is improved, but energy consumption increases
Solution Approach 1:
The heating elements operate periodically during desorption cycles rather than continuously, heating the sorbent to release carbon dioxide and then allowing cooling periods. This periodic operation improves carbon dioxide release efficiency while reducing overall energy consumption compared to continuous heating.
