Solution Overview
Problem
The use of hermetically sealed cells in optical components for ophthalmic lenses can result in aesthetic and optical drawbacks, such as visual hindrance and iridescence, due to light diffraction and scattering by the cells, especially when cell sizes exceed 0.5 mm, impacting the transparency and attractiveness of the lenses.
Innovation Solution
The optical component features a set of cells of varying sizes, with larger cells in central zones for aesthetics and smaller cells in peripheral zones to minimize diffraction and scattering, allowing for optimized transparency and adaptability of optical functions, while maintaining hermetic sealing to prevent substance mixing and allow for liquid or gel forms that enhance optical properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If large-sized cells are used in the optical component, then the optical function can be maintained and liquid/gel substances can be used, but the cells become visible and cause visual hindrance and aesthetic drawbacks
Solution Approach 1:
The patent applies local quality by differentiating cell sizes based on their location within the optical component. Central zones contain larger cells that can accommodate liquid or gel optical substances, while peripheral zones contain smaller cells that minimize visual hindrance. This spatial differentiation allows each region to optimize its function according to local requirements.
2Object-affected harmful factors
If small-sized cells are used to avoid visibility, then aesthetic appeal improves, but light diffraction and scattering cause iridescence and milky haze
Solution Approach 1:
The patent implements local quality by creating different cell size zones: central zones with larger cells that reduce diffraction and scattering effects, and peripheral zones with smaller cells that maintain aesthetic appeal. This spatial variation in cell dimensions allows the system to simultaneously address both optical performance and aesthetic requirements in different regions.
3Reliability
If hermetically sealed cells are used to prevent substance mixing, then optical function stability is improved, but the cell structure itself causes visibility and aesthetic drawbacks
Solution Approach 1:
The patent applies local quality by varying cell sizes across different zones of the optical component. Central zones use larger cells that maintain reliable hermetic sealing for optical function stability, while peripheral zones use smaller cells that are less visible and cause fewer aesthetic drawbacks. This spatial differentiation resolves the contradiction between reliability and aesthetics.
Solution Approach 2:
The patent segments the optical component into multiple zones with different cell characteristics. By dividing the component into central and peripheral zones with differently sized cells, the system can simultaneously achieve hermetic sealing reliability in central areas and aesthetic appeal in peripheral areas, resolving the contradiction through spatial segmentation.

AI summary
An optical component (10) comprises a transparent set of cells (15 ; 25) juxtaposed in parallel to a surface of the component. Each cell is hermetically sealed and contains a substance with an optical property. The set of cells comprises cells of several sizes. The size of the cells can be varied between various locations of the surface of the component (10), for making it possible to cut out the component without altering its optical properties . Furthermore, the variation in size of the cells serves to prevent diffraction or scattering from being visible in certain zones of the component.
