Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If carbon mass calculation stages and productivity evaluation stage are implemented, then productivity evaluation precision is improved, but device complexity increases
Solution Approach 1:
The productivity evaluation system is segmented into distinct functional stages: first carbon mass calculation stage for waste material, second carbon mass calculation stage for chemical substance, and productivity evaluation stage. This segmentation allows each stage to focus on specific calculations, improving precision while making the overall complex system manageable through modular design.
Solution Approach 2:
Carbon mass calculation serves as an intermediary parameter that bridges the waste material input and chemical substance output. By introducing this intermediate measurement layer, the system achieves more precise productivity evaluation without requiring direct complex measurement between input and output, thus managing system complexity.
2Loss of information
If carbon mass calculation and productivity evaluation are performed, then information completeness is improved, but loss of time increases
Solution Approach 1:
The system performs preliminary carbon mass calculations on waste material before the chemical conversion process. By preparing and measuring the carbon content of waste material in advance, the system ensures complete information tracking while reducing the time required during the actual productivity evaluation phase, as baseline data is already available.
