Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ophthalmic devices, such as contact lenses and intraocular lenses, face challenges in effectively controlling and coordinating the complex integration of electronics and optics to enhance vision and correct vision defects, particularly in accommodating for varying focal distances and presbyopia, due to the lack of precise ciliary muscle signal detection and processing.
Innovation Solution
The integration of a vibration sensor system within the ophthalmic device to detect ciliary muscle movements, which generates signals that control a variable-optic element to adjust the refractive power of the lens, allowing for real-time focus adjustments and compensation for presbyopia.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional contact lenses are designed with enhanced functionality including circuits and components, then vision enhancement and additional functionality are achieved, but device complexity increases
Solution Approach 1:
The contact lens integrates multiple functions including vision correction, ciliary muscle signal detection, and variable focus control within a single device. The sensor system detects ciliary muscle signals while the variable optic element adjusts focus, eliminating the need for separate devices and reducing overall system complexity.
Solution Approach 2:
The patent combines the ciliary muscle sensor, variable optic element, and control circuitry into an integrated contact lens system. This merging of components allows the lens to automatically respond to ciliary muscle signals and adjust focus without requiring external control devices.
2Measurement precision
If sensors and electronic components are integrated into contact lenses, then ciliary muscle signal detection capability is improved, but manufacturing complexity increases
Solution Approach 1:
The contact lens utilizes flexible thin film structures to integrate sensors and electronic components. This approach allows for precise signal detection while maintaining the lens's flexibility and ease of manufacturing through established contact lens fabrication techniques.
Solution Approach 2:
The patent replaces complex mechanical signal transmission systems with electronic sensors that directly detect ciliary muscle signals. This substitution simplifies the manufacturing process by eliminating精密 mechanical components while maintaining high detection precision.
3Adaptability or versatility
If a variable-optic element is incorporated into the lens, then focus adjustment capability is improved, but device complexity increases
Solution Approach 1:
The variable-optic element is controlled automatically by the sensor system that detects ciliary muscle signals. The lens self-adjusts focus without requiring external control inputs, simplifying the overall system by eliminating the need for separate control devices and interfaces.
Solution Approach 2:
The system implements a feedback loop where the sensor detects ciliary muscle signals and the control circuitry automatically adjusts the variable-optic element accordingly. This closed-loop control simplifies operation while maintaining precise focus adjustment capability.
