Solution Overview
Problem
Existing spectacle technologies lack efficient, electronic component-free methods for identifying and interacting with lenses to enhance user experience through customizable functionalities.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a predetermined identification structure is incorporated into spectacle lenses or frames, then lens identification and device interaction capabilities are improved, but manufacturing complexity increases
Solution Approach 1:
The patent applies optical filters that selectively transmit or block specific wavelengths of light to create identification structures. These filters can be applied as coatings on lenses or integrated into the lens material itself, allowing sensors to detect lens presence and type through optical property variations without adding mechanical complexity
Solution Approach 2:
The patent replaces potential mechanical identification systems with optical-based identification using filters and sensors. This substitution allows for non-contact, electronic-free detection of lens properties through optical property variations, simplifying the overall system while maintaining identification capabilities
2Ease of operation
If invisible identification structures are used in lenses, then user comfort and aesthetics are improved, but detection reliability must be maintained
Solution Approach 1:
The patent applies optical filters with specific spectral characteristics to localized regions of the lens or frame. These filters create distinct optical signatures that sensors can detect while remaining invisible to users. The local application of different filter properties allows reliable differentiation between lens types without affecting overall lens appearance or user comfort
Solution Approach 2:
The patent utilizes variations in optical parameters such as transmission wavelength, reflectivity, or absorption characteristics of the filters to create reliable identification signatures. By changing these optical parameters rather than physical dimensions, the system maintains detection reliability while preserving lens aesthetics and user comfort
