Problem
There is a need for an easy-to-apply device that can demonstrate various light-influencing properties, such as photochromism, polarization, and fixed tint, on corrective eyewear before purchase, as existing methods are complex and costly, and current solutions are limited in functionality and prone to optical irregularities.
Innovation Solution
A multi-layer experiential optical device comprising a first polymeric layer, a layer with light-influencing properties, and a second polymeric layer, with a low tack pressure-sensitive adhesive for reversible adhesion to optical lenses, allowing temporary experience of light-influencing properties without optical aberrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If optional functionalities (photochromism, polarization, fixed tint) are incorporated into the lens during manufacture, then the light-influencing properties are integrated and durable, but the manufacturing complexity and cost increase significantly
Solution Approach 1:
The optical device is divided into separate functional layers (photochromic layer, polarizing layer, fixed tint layer) that can be independently manufactured and then combined through lamination. This allows each layer to be optimized separately while simplifying the overall manufacturing process and reducing costs.
Solution Approach 2:
The patent uses composite material structures where multiple functional layers are laminated together. Each layer provides specific light-influencing properties, and their combination creates a multi-functional optical device that maintains durability while simplifying manufacturing compared to integrating all functions into a single lens material.
2Adaptability or versatility
If multiple optional functionalities are combined in a single lens, then comprehensive eye protection is achieved, but the processing complexity and cost increase
Solution Approach 1:
Different light-influencing functionalities are separated into distinct layers (photochromic layer, polarizing layer, fixed tint layer). Each layer can be manufactured using standard processes and then combined through lamination, making it easier to produce multi-functional lenses compared to incorporating all functions into a single complex manufacturing process.
Solution Approach 2:
The lamination structure serves as a universal platform that can accommodate multiple different functional layers. This multi-functional approach allows the same base structure to support various combinations of light-influencing properties without requiring different manufacturing processes for each combination.
3Ease of operation
If a patch is used to temporarily convert clear lenses to photochromic lenses, then the application is flexible and reversible, but optical irregularities such as air entrapment occur
Solution Approach 1:
The patent uses thin film layers that are laminated to the lens surface. These films are designed to conform to the lens curvature while maintaining optical uniformity, eliminating the air entrapment problems associated with thicker patches while preserving the flexibility and reversibility of temporary conversion.
Solution Approach 2:
Multiple functional layers are merged into a single laminated structure that is applied to the lens. This integration eliminates gaps and air entrapment between separate layers, ensuring optical uniformity while maintaining the ease of application and removal characteristic of temporary converters.
