Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional experimental methods (e.g., Gel Permeation Chromatography) are used to measure copolymer properties, then molecular weight and viscosity can be measured, but the effect of monomers on copolymer characteristics cannot be evaluated

Engineering Contradiction:
Improvecopolymer property measurementVSAvoidmonomer effect information
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The invention segments the copolymer system into individual monomer units and evaluates each monomer's contribution separately. By calculating monomer displacement values (α and β) and characteristic displacement values (λ) for each monomer type, the method isolates and quantifies the specific effect of each monomer on copolymer characteristics, thereby recovering the monomer effect information that conventional bulk measurement methods cannot provide.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the number and kind of monomers are varied to control copolymer characteristics, then copolymer properties can be optimized, but the complex and subtle actions of numerous monomers make it difficult to clearly evaluate their effects

Engineering Contradiction:
Improvecopolymer property controlVSAvoidmonomer effect evaluation
Core Design Contradiction:
Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The invention transforms the complex qualitative problem of monomer effects into quantitative parameters. By defining monomer displacement values (α, β) and characteristic displacement values (λ) as measurable parameters, the method enables systematic evaluation of how variations in monomer number, kind, and linkage type affect copolymer characteristics. This parameter-based approach makes the complex interactions detectable and measurable through mathematical relationships.

Inventive Principle:

AI summary

This invention relates to a method of evaluating monomers having an effect on copolymer characteristics and a system using the same, and particularly to a novel method of evaluating the magnitude of the effect of monomers on copolymer characteristics, which cannot be evaluated using existing methods. The method of evaluating monomers having an effect on copolymer characteristics and the system using the same are innovative because the extent of changes in copolymer characteristics can be predicted at the monomer level by quantitatively evaluating the effect of the monomers on the copolymer characteristics, taking into consideration the kind or linkage type of monomers.
