Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a predetermined procedure manual is used to adjust the operation support tool, then the operation process is standardized and easy to follow, but the system cannot adapt to real-time culture situation changes
Solution Approach 1:
The system continuously monitors culture data from the bioreactor and analyzer, compares actual culture state with target culture state, and automatically adjusts operation parameters based on the deviation. This closed-loop feedback mechanism enables real-time adaptation to culture situation changes without requiring complex manual intervention.
Solution Approach 2:
The operation support tool automatically generates and adjusts operation instructions based on real-time culture data analysis, eliminating the need for operators to manually interpret complex culture situations. The system serves itself by autonomously determining optimal operation parameters based on predefined culture models and real-time measurements.
2Reliability
If manual operation is used, then flexibility to adjust to culture changes is possible, but individual differences and human errors increase
Solution Approach 1:
The operation support tool acts as an intermediary between the operator and the bioreactor control system. It automatically generates operation instructions based on culture data analysis and presents them to the operator, who then executes them. This intermediary layer eliminates individual differences and human errors in decision-making while maintaining operational simplicity through clear, step-by-step instructions.
3Productivity
If real-time culture data analysis is performed continuously, then adaptive control is achieved, but data processing load and system response time increase
Solution Approach 1:
The system performs continuous monitoring of culture data but only triggers detailed analysis and control actions when culture parameters deviate from target ranges or when significant changes are detected. This partial action approach maintains high productivity by focusing computational resources on critical decision points rather than continuously processing all data points.
