Ophthalmic Lens with Embedded Data Processor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Contact lens wearers and those with intraocular lenses cannot easily change their vision correction without significant effort, as the optical qualities of traditional ophthalmic lenses are static and cannot be altered post-fabrication.
Innovation Solution
Incorporating a data processor and energy source into an ophthalmic lens, allowing for dynamic changes in lens components and optical qualities through controlled actinic radiation and energy management, enabling variable focal powers and enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional cast molding or lathing is used to form the lens, then the lens can be manufactured with predetermined optical quality, but the optical qualities remain static and cannot be changed after fabrication
Solution Approach 1:
The patent applies the dynamics principle by incorporating a data processor and energy source into the lens to enable dynamic adjustment of optical qualities. The lens transitions from a static structure with fixed optical properties to a dynamic system where the data processor can modify the optical state in response to user needs or environmental conditions, allowing focal power and other optical characteristics to change after fabrication.
Solution Approach 2:
The patent applies the nesting principle by embedding the data processor and energy source within the lens structure itself. The processor and power supply are integrated into the lens body, creating a compact nested arrangement where smaller components are housed within the larger lens structure, enabling adaptability without significantly increasing external dimensions.
2Adaptability or versatility
If a data processor and energy source are incorporated into the lens, then dynamic changes in optical qualities are enabled, but the device complexity increases
Solution Approach 1:
The patent applies the merging principle by combining the data processor, energy source, and lens components into a single integrated system. Rather than treating these as separate devices, they are merged into one unified ophthalmic lens assembly, reducing the number of discrete components and simplifying the overall system architecture while maintaining dynamic functionality.
Solution Approach 2:
The patent applies the universality principle by designing the lens to perform multiple functions: optical correction, dynamic focal adjustment, and potential additional functionalities controlled by the data processor. This multi-functional approach consolidates what would otherwise require separate devices into a single universal lens system.
3Adaptability or versatility
If the lens structure is made more complex to include dynamic components, then adaptability improves, but the ease of manufacture decreases
Solution Approach 1:
The patent applies the preliminary action principle by pre-positioning the data processor and energy source within the lens mold cavity before the lens material is formed. This preliminary placement allows the dynamic components to be integrated into the lens structure during the manufacturing process itself, rather than requiring complex post-fabrication assembly operations.
