Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the concentration of SO3 is not reduced before distillation, then the distillation process can proceed without additional treatment steps, but side products will occur during distillation
Solution Approach 1:
The patent applies preliminary action by removing excess SO3 from the reaction mixture before the distillation process. This is achieved by adding a specific amount of water to react with and remove SO3, thereby preventing side product formation during subsequent distillation while maintaining process simplicity
2Reliability
If an additive is added to remove SO3, then side products during distillation are prevented, but the process requires determination of the correct additive amount
Solution Approach 1:
The patent employs feedback by using conductivity and density measurements to determine the exact amount of water needed to remove SO3. The measured values are compared against predetermined ranges, allowing automatic or manual adjustment of water addition to achieve the desired SO3 removal without excessive complexity
Solution Approach 2:
The patent utilizes parameter changes by monitoring conductivity and density as indicators of SO3 concentration. By measuring these physical parameters and comparing them to established ranges, the system can determine the precise amount of water additive required, simplifying process control while ensuring reliable SO3 removal
3Extent of automation
If conductivity and density measurements are used to determine additive amount, then the process becomes systematic and controlled, but measurement and analysis steps are required
Solution Approach 1:
The patent replaces mechanical or manual estimation methods with electrical and physical measurement systems. Conductivity and density measurements provide objective, quantifiable data for determining additive dosage, enabling systematic and potentially automated control without requiring complex chemical analysis
