Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If neural networks are integrated into limit analysis and optimization systems, then measurement precision and manufacturing precision of compliance rules and portfolio optimization are improved, but device complexity increases due to the need to convert neural networks into compatible data structures
Solution Approach 1:
The patent introduces an intermediary conversion process that transforms neural networks into compatible data structures (such as directed acyclic graphs or decision trees) that can be integrated with existing optimization systems. This intermediary representation layer enables precise compliance rule evaluation while maintaining compatibility with traditional optimization frameworks, resolving the contradiction between improved precision and increased complexity.
Solution Approach 2:
The patent changes the parameter representation of neural networks by converting them into alternative data structures with different computational characteristics. By transforming the neural network into a decision tree or DAG format, the system maintains the predictive capabilities of machine learning while adapting to the constraint evaluation requirements of optimization systems, thereby improving precision without proportionally increasing complexity.
2Productivity
If neural networks are used as constraints and objective functions, then productivity and reliability of portfolio optimization are improved, but ease of operation deteriorates due to the complexity of integrating machine learning models
Solution Approach 1:
The patent creates simplified copies or representations of neural networks in the form of decision trees and directed acyclic graphs. These copied structures replicate the essential decision-making logic of the original neural networks but in a format that is more easily integrated with optimization systems. This copying approach enables high productivity through machine learning capabilities while improving ease of operation by using familiar, interpretable structures.
Solution Approach 2:
The patent develops a universal conversion framework that can transform various types of neural networks into multiple compatible data structures. This multi-functional approach allows the same conversion mechanism to handle different neural network architectures and optimize them for different purposes (constraints vs. objective functions), thereby improving productivity across diverse applications while maintaining ease of operation through a standardized process.
3Adaptability or versatility
If existing optimization frameworks are enhanced with neural networks, then adaptability of compliance rule handling is improved, but device complexity increases due to the integration of different computational paradigms
Solution Approach 1:
The patent implements dynamic adaptability by enabling optimization frameworks to flexibly incorporate neural network-based constraints and objective functions. The system can dynamically switch between traditional mathematical constraints and machine learning-based constraints, adjusting the computational paradigm based on the specific compliance requirements. This dynamic approach improves adaptability while managing complexity through conditional integration rather than permanent structural changes.
