Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single absorbent is used to achieve wide absorption bandwidth, then the absorption bandwidth is limited, but using two or more types of absorbents improves the absorption bandwidth while making it difficult to provide all absorbents with excellent solubility and compatibility with various solvents and resin components
Solution Approach 1:
The patent combines multiple absorbents (Compound 1, Compound 2, and Compound 3) into a single composition formulation. This merging approach allows the composition to achieve the wide absorption bandwidth of multiple absorbents while maintaining uniform solubility and compatibility characteristics throughout the entire composition, resolving the contradiction between bandwidth expansion and solubility reliability.
Solution Approach 2:
The patent creates a composite absorbent composition containing specifically designed compounds (Formula 1, Formula 2, and Formula 3) with complementary absorption characteristics. This composite material approach enables the composition to achieve wide absorption bandwidth while the carefully selected compounds collectively provide excellent solubility and compatibility with various solvents and resin components.
2Reliability
If the solubility or compatibility of the absorbent with the solvent or resin component is poor, then the spectral characteristics cannot be obtained, but improving solubility may compromise the optical characteristics due to precipitation
Solution Approach 1:
The patent modifies the molecular structure parameters of the absorbent compounds by introducing specific substituent groups (R111 to R117, R121 to R127, etc.) that can be adjusted to optimize both solubility and optical properties. By carefully selecting substituent types and positions, the composition achieves excellent solubility in various solvents while maintaining precise spectral characteristics without precipitation.
3Adaptability or versatility
If two or more types of absorbents are used to achieve wide absorption bandwidth, then the absorption bandwidth is improved, but it becomes difficult to provide all absorbents with suitable solubility and compatibility with various solvents and resin components simultaneously
Solution Approach 1:
The patent designs the absorbent composition with compounds that possess universal solubility and compatibility characteristics, allowing the same composition formulation to work with various solvents and resin components. This multi-functionality approach enables the composition to achieve wide absorption bandwidth while maintaining consistent performance across different application systems without requiring separate formulations for each solvent or resin type.
