Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the refractive index of an optical material is increased, then the lens can be made thinner and lighter, but the Abbe's Number becomes low and transparency is compromised
Solution Approach 1:
The patent changes the chemical composition parameters of the resin by incorporating specific monomers with high electron density (containing oxygen or sulfur atoms in aromatic rings) to achieve high refractive index while maintaining transparency. This resolves the contradiction by adjusting material parameters rather than changing the fundamental optical relationship between refractive index and transparency.
Solution Approach 2:
The patent creates a composite resin system by combining multiple monomers with complementary properties - specifically using monomers containing aromatic rings with oxygen or sulfur atoms to achieve both high refractive index and high transparency. This composite approach allows the material to simultaneously satisfy both optical requirements that cannot be met by single-component materials.
2Length of moving object
If the refractive index of an optical material is increased, then the lens can be made thinner and lighter, but the Abbe's Number becomes low
Solution Approach 1:
The patent adjusts the chemical structure parameters by selecting monomers with specific molecular weights and chemical compositions (containing aromatic rings with oxygen or sulfur) to achieve the desired balance between refractive index and Abbe's Number. This parameter optimization allows simultaneous achievement of thin lens design and acceptable dispersion characteristics.
Solution Approach 2:
The patent introduces specific functional groups (aromatic rings with oxygen or sulfur atoms) at specific positions within the polymer chain to locally enhance electron density and refractive index while maintaining overall molecular structure that preserves transparency and acceptable Abbe's Number. This localized structural modification allows targeted optimization of optical properties.
