Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If CO2 absorption material is deposited on the medium surface, then CO2 capture capacity is improved, but pressure drop increases
Solution Approach 1:
The patent applies local quality by depositing CO2 absorption material selectively on specific zones of the medium surface rather than uniformly across the entire surface. This creates areas with different properties: some regions have absorption material for CO2 capture, while other regions remain open for airflow, thereby balancing CO2 capture capacity with acceptable pressure drop characteristics
Solution Approach 2:
The patent implements partial action by covering only a portion (4-30%) of the medium surface with absorption material rather than complete coverage. This partial deposition provides sufficient CO2 capture functionality while maintaining adequate airflow pathways, thus preventing excessive pressure drop in the ventilation system
2Quantity of substance
If CO2 absorption material coverage is increased, then CO2 absorption capacity is improved, but ventilation system compatibility deteriorates
Solution Approach 1:
The patent applies parameter changes by optimizing the coverage percentage of absorption material (4-30%) as a critical design parameter. This specific range was determined to provide the optimal balance between CO2 absorption capacity and pressure drop characteristics, ensuring compatibility with standard ventilation systems that have specified pressure drop limits

AI summary
The invention relates to a CO2 absorption cartridge configured to be integrated into a ventilation system of a building so as to be arranged in the passage of air. The absorption cartridge comprises an air-permeable media mounted on a frame and deposits of CO2 absorption material which are made on the media. The percentage of coverage of the absorption material on the surface of the media is defined as a function of an initial pressure drop of the air flow which is allowed, by the ventilation system, to the passage of the media in order to maintain suitable ventilation of the building. The invention also relates to a ventilation system, a method for manufacturing the cartridge and the installation for implementing the method.
