Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If generative AI systems are used to generate new materials and designs, then creativity and exploration of new material spaces are improved, but efficiency in generating materials with specific user-defined properties deteriorates
Solution Approach 1:
The system implements feedback loops where user preferences and experimental results are continuously incorporated to refine and update the generative AI models. This allows the system to learn from outcomes and improve its ability to generate materials with desired properties, resolving the contradiction between creative exploration and targeted efficiency
Solution Approach 2:
The generative AI systems are designed to be dynamic and adaptable, allowing users to adjust parameters, constraints, and objectives in real-time. This dynamic capability enables the system to switch between exploratory generation and targeted property optimization, accommodating both diversity and specificity requirements
2Measurement precision
If comprehensive data analysis and model tuning are implemented, then accuracy in predicting material properties is improved, but processing time and computational resources increase
Solution Approach 1:
The system performs preliminary actions by pre-processing and organizing material data, pre-training models on extensive datasets, and establishing baseline predictions before actual material design tasks. This preliminary preparation reduces the computational burden and time required during interactive design sessions while maintaining high prediction accuracy
Solution Approach 2:
The system applies different levels of analysis and model complexity to different aspects of material design. Rather than uniformly applying comprehensive analysis to all tasks, it selectively intensifies computational resources for critical property predictions while using simplified models for routine evaluations, optimizing the balance between accuracy and processing time

AI summary
Disclosed embodiments provide methods, systems, and computer program products for implementing constrained generation for material discovery and material design using generative artificial intelligence (AI) foundation models. A disclosed non-limiting method includes providing, using one or more processors, a chemical structure at a user design interface; receiving, at a foundation model, a user selection of a portion of the chemical structure and a user-input prompt for replacing the portion, where the user-input prompt indicates a desired property of a replacement portion; and generating, by the foundation model, the replacement portion, where the replacement portion replaces the selected portion of the chemical structure and includes a generated chemical structure predicted to have the desired property.
