Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sunglasses are often chosen based on aesthetics rather than the wearer's specific environment and activities, leading to suboptimal color vision performance.
Innovation Solution
A method using a processing unit to select a lens with a light transmission filter based on environmental images, analyzing dominant colors and their modifications through different filters to determine the ideal lens for a given environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sunglasses are chosen based on frame aesthetic rather than solar filter, then ease of selection is improved, but color vision performance deteriorates
Solution Approach 1:
The patent applies color changes by analyzing the dominant colors in environmental images and selecting lenses with filters that optimize color perception for those specific color conditions. The system transforms the selection criterion from aesthetic preference to scientifically-determined color optimization based on the wearer's environment.
2Device complexity
If a fixed filter is used for all environments, then device complexity is reduced, but adaptability to different environments deteriorates
Solution Approach 1:
The patent implements dynamics by enabling the lens filter selection to adapt dynamically based on the environment. Instead of a fixed filter, the system determines the optimal filter by analyzing environmental images and selecting from multiple predetermined filters based on color matching algorithms, allowing the solution to adjust to different environmental conditions.
3Measurement precision
If multiple environmental images are processed to identify main colors, then measurement precision of color characteristics is improved, but processing time increases
Solution Approach 1:
The patent applies partial or excessive action by processing multiple environmental images to identify dominant colors, using more images than strictly necessary to achieve sufficient precision. This approach prioritizes measurement accuracy over minimal processing, accepting increased processing time as a trade-off for robust color characterization.

AI summary
The invention relates to a selecting method for selecting a lens amongst predetermined lenses having distinct light transmission filters, depending on an environment in which said lens is to be used, comprising steps of: - providing at least one image of said environment, - identifying a predetermined number of main colors on said at least one image, - estimating a first value of at least a color component for each main color, - determining a modified color corresponding to said main color seen through a first of said predetermined lenses, - calculating a second value of said color component for each modified color, - repeating the determining and calculating steps for each of the other predetermined lenses, - comparing, for each main color, said first value to each second value, and - deducing therefrom a selected lens.
