Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional high refractive index monomers are used, then the refractive index of optical sheets is improved, but yellowing phenomenon occurs reducing transmittance
Solution Approach 1:
The patent changes the chemical structure parameters of the monomer by introducing triazine derivative compounds with specific molecular structures (Chemical Formulas A to C) that inherently provide high refractive index while maintaining resistance to yellowing, thus resolving the contradiction through material composition optimization
Solution Approach 2:
The patent creates a composite photosensitive composition containing the triazine derivative compound combined with other monomers and oligomers, achieving synergistic effects where the triazine derivative provides high refractive index and anti-yellowing properties while other components contribute to curability and mechanical properties
2Illumination intensity
If conventional high refractive index monomers are used, then luminance enhancement is attempted, but curability is insufficient
Solution Approach 1:
The patent optimizes the molecular structure parameters of the monomer by incorporating photopolymerizable groups (acrylate, methacrylate, vinyl) into the triazine derivative structure, enabling effective photocrosslinking and achieving high curability while maintaining high refractive index for luminance enhancement
Solution Approach 2:
The patent uses photoinitiators as intermediaries that absorb UV light and generate reactive species to initiate polymerization of the triazine derivative monomer, bridging the gap between the monomer's high refractive index property and the need for effective curability
3Illumination intensity
If conventional high refractive index monomers are used, then refractive index is increased, but transmittance deteriorates
Solution Approach 1:
The patent carefully selects and optimizes the chemical structure parameters of the triazine derivative, including aromatic ring substitutions and side chain configurations, to achieve high refractive index while maintaining good light transmittance by avoiding structures that cause strong light absorption
