Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If polyester carbonate is added to curable resin, then mechanical strength and heat resistance are improved, but compatibility deteriorates causing phase separation and interface peeling
Solution Approach 1:
The invention changes the chemical structure parameters of the polyester carbonate by incorporating specific structural units (formulae 1-3) with reactive functional groups. This structural modification enables chemical bonding between polyester carbonate and curable resin, transforming physical mixing into chemical integration, thereby resolving the compatibility issue while maintaining mechanical strength enhancement
Solution Approach 2:
The invention creates a composite curable resin system where polyester carbonate containing specific structural units is integrated with curable resin components. The composite structure allows synergistic effects: polyester carbonate provides mechanical strength and heat resistance, while the curable resin matrix ensures compatibility and structural integrity through chemical crosslinking
2Ease of manufacture
If conventional polyester carbonate is used, then production cost is reduced, but dielectric properties deteriorate
Solution Approach 1:
The invention modifies the chemical composition parameters of polyester carbonate by incorporating specific structural units with controlled molar ratios. This parameter optimization achieves low dielectric constant and loss tangent values suitable for electronic applications, while maintaining cost-effectiveness through efficient use of raw materials and standardized production processes
3Stability of the object's composition
If polyester carbonate with high compatibility is used, then phase separation is reduced, but dielectric constant and loss tangent increase
Solution Approach 1:
The invention precisely controls the molar ratios of structural units (formulae 1-3) in polyester carbonate to optimize dielectric properties. By adjusting these compositional parameters, the invention achieves low dielectric constant and loss tangent while maintaining sufficient compatibility through the reactive functional groups, resolving the trade-off between compatibility and dielectric performance
