Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If semiconductor devices and active electronic components are embedded in an ophthalmic lens, then the functionality and optical characteristic control are enhanced, but the device complexity increases and biocompatibility challenges arise
Solution Approach 1:
The insert is divided into multiple pieces (first insert piece and second insert piece) that are separately formed and then joined together. This segmentation allows for easier manufacturing of complex electronic components while maintaining the overall functionality within the ophthalmic lens device
Solution Approach 2:
The multi-piece insert with embedded semiconductor devices and electronic components is nested within the ophthalmic lens. The insert pieces are joined together to form a compact structure that contains multiple functional elements (electrodes, conductive traces, semiconductor devices) within a small space suitable for contact lens integration
2Ease of manufacture
If multiple insert pieces are joined together to form a multi-piece insert, then the manufacturing flexibility and component integration are improved, but the sealing reliability becomes more challenging
Solution Approach 1:
The first and second insert pieces are formed separately with pre-defined joining surfaces before being joined together. This preliminary formation allows for precise surface preparation and alignment features to be incorporated, ensuring reliable sealing and electrical connections when the pieces are assembled
Solution Approach 2:
A joining mechanism serves as an intermediary between the first and second insert pieces, providing both mechanical attachment and sealing functionality. The joining structure creates fluid-tight seals while maintaining electrical connectivity for the embedded components
3Adaptability or versatility
If electrodes and conductive traces are integrated into the insert pieces, then the wireless power transmission capability is enabled, but the manufacturing precision requirements increase
Solution Approach 1:
Conductive traces and electrodes are selectively integrated into specific regions of the insert pieces where needed for electrical connectivity and wireless power transmission. This localized integration allows for precise control of electrical properties in critical areas while simplifying manufacturing in non-critical regions
