Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If temperature adjustment is performed to simulate actual working conditions, then measurement accuracy of absorbent loss rate is improved, but device complexity increases due to addition of temperature adjustment device and external circulation pipeline
Solution Approach 1:
The patent creates a simplified test system that copies the essential features of industrial carbon capture processes. The temperature adjustment device simulates the temperature variations experienced by absorbents in actual industrial settings, allowing accurate measurement of absorbent loss rates without requiring a full-scale industrial system. This copying approach enables precise measurement while maintaining manageable device complexity.
2Adaptability or versatility
If external circulation pipeline and temperature adjustment device are added, then ability to simulate actual working conditions is improved, but ease of operation deteriorates due to increased system complexity
Solution Approach 1:
The external circulation pipeline and temperature adjustment device serve multiple functions: they simulate temperature variations in actual working conditions, enable measurement of absorbent loss rates under different temperature conditions, and provide a controlled environment for testing different absorbents. This multi-functionality improves adaptability while the integrated design maintains operational simplicity.
3Productivity
If absorbent replenishment is performed without accurate loss rate data, then carbon capture process continuity is maintained, but carbon capture efficiency deteriorates due to improper replenishment timing and amount
Solution Approach 1:
The detection assembly provides feedback on absorbent loss rates by measuring the concentration of absorbents in the circulating solution. This feedback mechanism enables operators to determine the actual absorbent loss rate under simulated working conditions, allowing for optimized replenishment decisions that maintain carbon capture efficiency while avoiding both under-replenishment and over-replenishment.
