Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users with vision problems like myopia experience visual fatigue and discomfort due to constant eye adjustments when switching between near and far distances, requiring multiple pairs of glasses with different diopter strengths, which is inconvenient and costly.
Innovation Solution
A method and device that adjust the diopters of glasses based on positioning information and naked eye visual acuity using a diopter mapping table, automatically changing diopter strengths to match the user's environment, reducing eye strain and eliminating the need for multiple glasses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users wear glasses with fixed high diopters for long distance viewing, then distant vision is improved, but near viewing causes increased eye strain and visual fatigue
Solution Approach 1:
The patent applies dynamics by making the diopter value changeable rather than fixed. The glasses automatically adjust the lens diopter based on the user's viewing distance, transitioning from static to dynamic optical correction. This resolves the contradiction by providing high diopters for distant viewing while reducing diopters for near viewing, eliminating eye strain across different viewing scenarios.
Solution Approach 2:
The patent changes the optical parameter (diopter value) of the lenses based on viewing conditions. By detecting viewing distance and adjusting the corresponding diopter parameter, the system optimizes visual correction for each scenario - using higher diopters for distant objects and lower diopters for near objects, thereby preventing visual fatigue while maintaining clear vision at all distances.
2Object-affected harmful factors
If users wear glasses with lower diopters for near viewing, then eye strain is reduced, but distant vision becomes blurred
Solution Approach 1:
The system dynamically adjusts diopter values based on real-time detection of viewing distance. When the user views distant objects, the system automatically increases the diopter to ensure clear vision; when viewing near objects, it reduces the diopter to minimize eye strain. This dynamic adaptation resolves the contradiction between near viewing comfort and distant vision clarity.
Solution Approach 2:
The patent changes the optical parameter (diopter) according to viewing distance parameters. By establishing a correspondence between detection parameters (viewing distance) and optical parameters (diopter), the system automatically selects the appropriate diopter value - lower for near viewing to reduce strain, higher for distant viewing to maintain acuity.
3Object-affected harmful factors
If users purchase multiple pairs of glasses with different diopters for different viewing distances, then visual comfort is improved, but device complexity and cost increase
Solution Approach 1:
The patent makes a single pair of glasses universal by equipping it with automatic diopter adjustment capability. Instead of requiring separate glasses for different viewing distances, one intelligent glasses pair can adapt to various scenarios through automated optical parameter changes. This multi-functionality resolves the contradiction by providing visual comfort across all distances while eliminating the need for multiple glasses pairs.
Solution Approach 2:
The glasses perform self-adjustment by automatically detecting viewing distance and changing diopter values without user intervention. The system uses sensors to detect viewing conditions and autonomously adjusts the optical parameters, making the glasses self-adaptive to different scenarios. This self-service capability eliminates the need for users to manually switch between multiple glasses pairs.
