Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional resin adhesive layers are used in cemented lenses, then the lens can be manufactured with standard materials, but the chromatic aberration correction is insufficient due to limited refractive index and dispersion characteristics
Solution Approach 1:
The patent modifies the chemical structure of resin adhesive layers by incorporating specific functional groups and molecular configurations that alter refractive index and dispersion characteristics. This enables the resin to achieve superior chromatic aberration correction while maintaining manufacturability with standard cemented lens processes.
Solution Approach 2:
The invention develops composite resin adhesive materials that combine multiple chemical components with complementary optical properties. These composite resins achieve enhanced dispersion characteristics and refractive index control, resolving the contradiction between manufacturing feasibility and optical performance.
2Manufacturing precision
If resin adhesive layers with enhanced optical properties are developed, then chromatic aberration correction improves, but the complexity of material synthesis and formulation increases
Solution Approach 1:
The patent divides the resin adhesive formulation into distinct functional components, each contributing specific optical properties. This segmentation allows for systematic optimization of chromatic aberration correction while maintaining manageable synthesis procedures for each component.
Solution Approach 2:
The invention introduces intermediary chemical structures that facilitate the combination of different functional groups within the resin adhesive. These intermediary structures simplify the overall synthesis pathway while enabling the final material to achieve superior dispersion characteristics and refractive index control.
