Adapter for Electro-Active Spectacle Lenses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electro-active spectacle lenses are not compatible with most pre-existing frame designs, requiring unique design or modification of the frame to function effectively, which affects aesthetics and functionality.
Innovation Solution
An adapter system that houses electro-active lenses within a standard spectacle frame, incorporating focus sensors, drive electronics, and power sources, allowing for automatic and manual control without modifying the frame, and synchronizing lenses using various communication methods such as wireless optical, RF, inductive coupling, or vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electro-active lenses are integrated directly into spectacle frames, then functional operation is achieved, but frame design flexibility and aesthetic selection are reduced
Solution Approach 1:
The system is divided into separate functional modules: electro-active lenses with integrated electronics, adapters that interface with standard frame mounting locations, and frame structures. This segmentation allows lenses to be manufactured with precise electronic integration while frames remain simple mechanical structures, resolving the contradiction between functionality and design flexibility
Solution Approach 2:
The adapter serves multiple functions: it provides mechanical mounting for the lens, establishes electrical connections between the lens electronics and frame, and maintains aesthetic appearance. This multi-functionality allows a single component to address multiple requirements without increasing overall system complexity
2Ease of operation
If control electronics and power sources are integrated into the lenses, then automatic and manual control is enabled, but lens weight and size increase
Solution Approach 1:
The system distributes components across different spatial dimensions and locations: lightweight flexible circuits are embedded within the lens substrate, while heavier components like batteries and motors are positioned in the frame or temples. This dimensional distribution maintains lens thinness and aesthetic appearance while enabling full control functionality
3Reliability
If multiple components are incorporated internally to the lens body, then full functionality is achieved, but aesthetic appearance and mounting compatibility are compromised
Solution Approach 1:
Flexible transparent or translucent films and circuits are used within the lens structure to minimize visual impact. These thin-film technologies allow electronic components to be integrated without significantly altering the lens appearance, maintaining aesthetic appeal while ensuring reliable functional operation

AI summary
An adapter ( 202 ) for a spectacle frame ( 104 ) is disclosed which is configured for enabling the spectacle frame to operate and control electro-active lenses ( 201 ) housed therein. In particular, the spectacle frame may allow electro-active lenses housed therein to focus and be controlled both automatically and manually with heretofore unrealized results.
