Variable Optical Filter Eyewear for Interocular Sensory Imbalance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eye patches for correcting interocular sensory imbalance are ineffective in varying light conditions, as their light-blocking effect is dependent on environment light intensity, leading to inconsistent correction across different settings.
Innovation Solution
Eyewear with a variable optical filter system, including a light sensor and analysis module that adjusts a target illuminance ratio by controlling the optical state of the filter structure based on detected incident light, ensuring consistent correction across different light conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed patch is used to correct interocular sensory imbalance, then correction is provided in one light condition, but the correction effect becomes inconsistent in varying light conditions
Solution Approach 1:
The patent applies the dynamics principle by replacing the fixed optical patch with a variable optical filter system that can dynamically adjust its light transmission properties. The filter structure changes its optical density in real-time based on ambient light conditions detected by sensors, allowing the system to maintain consistent correction效果 across different lighting environments rather than being static and condition-dependent
Solution Approach 2:
The patent implements parameter changes by modifying the optical density parameter of the filter structure according to ambient illuminance levels. The control module adjusts the optical density parameter dynamically - increasing it in bright conditions and decreasing it in dim conditions - to maintain a consistent target illuminance ratio between eyes, thereby resolving the inconsistency problem of fixed patches
2Reliability
If the patch darkness is increased to block more light for stronger interocular imbalance, then better correction is achieved for severe cases, but the correction becomes overly strong for mild cases or bright conditions
Solution Approach 1:
The patent applies feedback control by using light sensors to continuously monitor ambient illuminance levels and feed this information to the control module. The control module then adjusts the filter structure's optical density based on this feedback, automatically adapting the correction intensity to match both the severity of interocular imbalance and the current lighting conditions, eliminating the need for manual adjustment
Solution Approach 2:
The system performs self-service by automatically detecting ambient light conditions and adjusting its own optical properties without external intervention. The eyewear autonomously regulates the light transmission through the filter structure based on real-time environmental sensing, providing adaptive correction that responds to both lighting changes and the wearer's specific interocular imbalance characteristics
