Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If cells are cultured for a certain period to evaluate differentiation level, then differentiation level can be evaluated, but time and resources are wasted
Solution Approach 1:
The patent applies preliminary action by measuring miRNA content in exosomes from culture supernatant before differentiation induction begins. This allows prediction of future differentiation level without requiring cells to be cultured for a certain period, thereby avoiding time waste while maintaining evaluation accuracy.
Solution Approach 2:
The patent uses miRNA in exosomes as an intermediary marker to predict differentiation level. Instead of directly measuring differentiation status after culture, the miRNA content in exosomes serves as a predictive indicator that can be measured beforehand, eliminating the need for time-consuming direct evaluation.
2Measurement precision
If cells are cultured for a certain period to evaluate differentiation level, then differentiation level can be evaluated, but resource utilization is inefficient
Solution Approach 1:
The patent performs the evaluation action in advance by measuring miRNA content before differentiation induction. This preliminary measurement eliminates the need to wait for culture completion, thereby improving resource utilization and productivity while maintaining accurate differentiation level assessment.
Solution Approach 2:
The patent employs miRNA in exosomes as a resource-efficient intermediary marker. This marker allows remote prediction of differentiation level without requiring direct cell analysis or extended culture, thus optimizing resource utilization while preserving measurement precision.
3Productivity
If differentiation induction is performed without prediction, then cells can be differentiated, but unnecessary operations are performed
Solution Approach 1:
The patent implements feedback by using miRNA content measurement to predict differentiation level before induction. This prediction serves as feedback information that can guide whether differentiation induction is necessary, preventing unnecessary operations and reducing time loss.
Solution Approach 2:
The patent performs prediction action before differentiation induction by measuring miRNA content. This preliminary prediction allows decision-making about whether to proceed with induction, avoiding unnecessary operations and optimizing both productivity and time efficiency.
