Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional analytical approaches and supervised learning are used to build prediction models, then the model development process is straightforward and controllable, but the model fails to identify complex and subtle correlations between production parameters and product properties
Solution Approach 1:
The patent replaces traditional analytical and supervised learning methods with reinforcement learning algorithms. This substitution enables the system to automatically explore and identify complex, non-linear correlations between production parameters and product properties without requiring pre-defined hypotheses or manual feature engineering, thereby achieving higher prediction accuracy for complex polymeric product relationships.
Solution Approach 2:
The patent transforms the prediction model development approach by changing from static, hypothesis-driven parameter relationships to dynamic, exploration-driven parameter optimization. The reinforcement learning agent continuously adjusts model parameters based on feedback from production data, enabling the system to adapt to subtle and complex correlations that traditional methods miss.
2Measurement precision
If reinforcement learning is used to develop prediction models, then the model can identify complex and subtle correlations, but the computational resources and time required increase significantly
Solution Approach 1:
The patent implements preliminary action by using reinforcement learning to pre-train prediction models on historical production data before actual production scenarios. This allows the model to learn complex correlations in advance, so that during actual production, the model can provide accurate predictions quickly without requiring extensive real-time computation or iteration.
3Measurement precision
If reinforcement learning is used to develop prediction models, then explorative capabilities improve and complex correlations are identified, but the computational resources required increase
Solution Approach 1:
The patent applies partial action by implementing reinforcement learning selectively for identifying complex correlations in specific production scenarios rather than applying it universally. The system uses reinforcement learning exploratively only when traditional methods fail to achieve sufficient accuracy, thereby reducing overall computational resource consumption while still capturing the benefits of explorative model development where needed.
