Composite Material Estimation via Numerical Characteristic Values
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing physical quantity estimating systems for composite materials face challenges in accurately estimating the value of physical quantities when new constituent materials not used in the training data are included, due to the use of material names as input parameters, which limits the applicability and accuracy of the estimation.
Innovation Solution
The system employs characteristic values of constituent materials expressed as numerical values for input parameters, allowing for the synthesis and estimation of physical quantities for composite materials containing new constituent materials by generating an approximate function based on these values and blending ratios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If material names are used as input parameters for estimation, then the system can estimate physical quantities for composite materials within the training data range, but the system cannot accurately estimate physical quantities for composite materials containing new constituent materials not used in training
Solution Approach 1:
The patent transforms the input parameters from categorical material names to numerical characteristic values. This parameter transformation enables the approximate function to process quantitative relationships between constituent materials and their physical quantities, allowing accurate estimation even for new materials whose characteristic values can be measured or obtained, thus resolving the contradiction between estimation accuracy and applicability to new materials
Solution Approach 2:
The patent introduces characteristic values as an intermediary between material names and physical quantities. Instead of directly mapping material names to physical quantities, the system uses characteristic values (such as molecular weight, viscosity, or other measurable properties) as a mediator. This intermediary enables the system to handle new materials by measuring their characteristic values and using these numerical values in the approximate function, thereby expanding applicability while maintaining estimation accuracy
2Adaptability or versatility
If characteristic values are used as input parameters instead of material names, then the system can estimate physical quantities for composite materials with new constituent materials, but the system complexity increases due to the need to manage and process numerical characteristic data
Solution Approach 1:
The patent creates a universal approximate function that can handle both existing and new constituent materials through a unified numerical parameter system. The characteristic value-based approach allows the same estimation function to work for any material whose characteristic values can be obtained, eliminating the need for separate handling procedures for new materials and thus managing complexity through universality
3Measurement precision
If comprehensive training data covering all possible constituent materials is collected, then the system can accurately estimate physical quantities for any composite material, but the data collection and preparation time and costs increase enormously
Solution Approach 1:
By changing from material-name-based parameters to characteristic value-based parameters, the system transforms the problem from requiring comprehensive material-specific training data to requiring general relationships between characteristic values and physical quantities. This parameter transformation enables the system to handle new materials without needing their specific training data, thus reducing data preparation time and costs while maintaining estimation accuracy
