Solution Overview
Problem
Existing methods for determining eye parameters, such as interpupillary distance, are complex, time-consuming, and often require the assistance of an eye care professional or specialized equipment, making them inaccessible for self-measurement.
Innovation Solution
A method using a binocular display device that displays images independently to each eye, allowing users to adjust display parameters until the image quality is optimal, thereby determining eye parameters like interpupillary distance through subjective feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional mirror method is used to measure interpupillary distance, then measurement can be performed without professional equipment, but the measurement process becomes complex and time-consuming
Solution Approach 1:
The patent replaces the mechanical mirror method with an optical system using a light source, camera, and image processing algorithm. The camera captures images of the user's eyes, and software automatically calculates interpupillary distance, eliminating the need for manual mirror alignment and ruler measurements.
Solution Approach 2:
The system enables users to perform self-measurement of interpupillary distance without requiring professional eye care practitioners or complex equipment. The automated image capture and processing allows users to obtain accurate measurements independently through a simplified digital interface.
2Measurement precision
If professional eye care practitioners perform measurements, then measurement accuracy is ensured, but the process requires specialized personnel and equipment
Solution Approach 1:
The patent creates a digital copy of the eye measurement process by capturing images with a standard camera and using image processing algorithms to extract interpupillary distance. This digital replication eliminates the need for specialized optical equipment and trained professionals while maintaining measurement accuracy through automated feature detection.
Solution Approach 2:
The system changes the measurement parameters from manual visual estimation to automated digital image analysis. By converting physical measurements into digital image processing tasks, the system achieves high precision without requiring complex equipment or expert knowledge.
3Reliability
If multiple measurements are repeated to ensure accuracy, then measurement reliability improves, but the process becomes longer and more complex
Solution Approach 1:
The system incorporates feedback mechanisms where the camera captures multiple images and the software automatically validates results through algorithmic processing. The system can detect and correct measurement errors automatically, ensuring reliability without requiring manual repetition of measurements by the user.
Solution Approach 2:
The patent performs preliminary image capture and processing steps automatically before final measurement calculation. The system pre-processes images to identify eye features, aligns multiple captures if needed, and prepares data for analysis, thereby ensuring measurement reliability while maintaining efficiency through automated workflows.
