Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
ImproveCO2 conversion rateVSAvoiddevice construction complexity
Core Design Contradiction:
ProductivityVSDevice complexity

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If significant compression and cooling capacity is provided for CO2 removal, then CO2 separation efficiency is improved, but energy consumption increases

Engineering Contradiction:
ImproveCO2 separation efficiencyVSAvoidenergy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

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.

Inventive Principle:
Principle #25Self-service

3Productivity

If massive circulation capacities are provided for CO2 removal, then CO2 conversion is improved, but energy consumption and device complexity increase

Engineering Contradiction:
ImproveCO2 conversion efficiencyVSAvoidcirculation energy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

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.

Inventive Principle:
Principle #19Periodic action

4Productivity

If active technical CO2 separation is implemented, then CO2 removal efficiency is improved, but construction costs and device complexity increase

Engineering Contradiction:

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.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
