Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If photosynthesis-based CO2 removal devices are designed for large-scale operation, then CO2 conversion efficiency is improved, but device complexity and construction costs increase
Solution Approach 1:
The device is divided into multiple independent modules, each containing a portion of the photosynthetic organism population. This segmentation allows for easier construction, maintenance, and scaling while maintaining high overall CO2 conversion efficiency through parallel operation of multiple modules.
Solution Approach 2:
The device structure is designed to serve multiple functions: CO2 removal through photosynthesis, biomass production, and potential energy generation. This multi-functionality reduces the need for separate systems and decreases overall device complexity while maintaining high productivity.
2Productivity
If significant compression and cooling capacity is provided for CO2 removal, then CO2 separation efficiency is improved, but energy consumption increases
Solution Approach 1:
The system uses the photosynthetic organisms' natural ability to separate and convert CO2 without requiring external compression or cooling systems. The organisms self-regulate CO2 uptake based on their metabolic needs, eliminating the need for energy-intensive mechanical separation processes while maintaining high CO2 removal efficiency.
3Productivity
If massive circulation capacities are provided for CO2 removal, then CO2 conversion is improved, but energy consumption and device complexity increase
Solution Approach 1:
Instead of continuous massive circulation, the system employs periodic gas flow patterns that allow photosynthetic organisms to efficiently process CO2 during active periods. This periodic operation reduces energy consumption for gas circulation while maintaining high CO2 conversion rates through optimized timing and flow rates.
4Productivity
If active technical CO2 separation is implemented, then CO2 removal efficiency is improved, but construction costs and device complexity increase
Solution Approach 1:
The system replaces complex mechanical CO2 separation systems with a biological photosynthesis-based approach. Photosynthetic organisms naturally perform CO2 separation and conversion through their metabolic processes, eliminating the need for expensive and complex mechanical separation equipment while achieving high CO2 removal efficiency.

Function Achieved in This Case
The system achieves high CO2 conversion rates with reduced resource consumption and costs, making it suitable for industrial-scale CO2 removal, particularly in regions with high solar radiation like deserts, and can be integrated with power plants for CO2-free operation.
Implementation Method 1
A system for maintaining a favorable atmosphere in a greenhouse is known from WO 97/12511, in which exhaust gas containing water vapor and CO2 is generated by means of a burner operated with hydrocarbon fuel and is fed into the greenhouse after it has been cooled.
