Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing vinyl-group-containing compounds are used, then optical properties such as light transmittance and refractive index are maintained, but reactivity is insufficient for high-performance applications
Solution Approach 1:
The patent modifies the chemical structure of vinyl-group-containing compounds by introducing specific substituents (W1, W2, W3 groups) at defined positions on the fluorene skeleton, changing molecular parameters to enhance reactivity while preserving optical properties. This structural parameter optimization enables the compounds to achieve both high reactivity and broad application versatility.
Solution Approach 2:
The invention creates composite molecular structures by combining the fluorene skeleton with vinyl groups and various substituent groups (W1, W2, W3), forming a composite material that integrates the optical stability of the fluorene core with the reactivity of vinyl groups, achieving both maintained optical properties and improved reactivity.
2Manufacturing precision
If compounds with enhanced reactivity are developed, then micropatterning capabilities improve, but manufacturing complexity increases
Solution Approach 1:
The patent introduces specific functional groups (W1, W2, W3) at localized positions on the fluorene skeleton rather than uniformly modifying the entire structure. This localized modification approach enhances micropatterning capability at specific sites while keeping the overall molecular structure relatively simple and manageable for manufacturing.
3Reliability
If novel vinyl-group-containing compounds are synthesized, then optical and thermal properties are improved, but production cost increases
Solution Approach 1:
The patent divides the molecular structure into distinct segments (fluorene skeleton, vinyl groups, and substituent groups W1, W2, W3) that can be independently optimized and synthesized. This segmentation allows for modular synthesis approaches, improving optical and thermal properties through targeted structural modifications while facilitating more efficient production processes.
