Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional optometry methods are used to measure pupillary distance and optical axis alignment, then the optometry process can be completed, but measurement inaccuracies occur leading to prism effects and visual discomfort
Solution Approach 1:
The patent replaces conventional mechanical measurement instruments with a digital imaging system that uses cameras and image processing algorithms to measure pupillary distance and optical axis alignment. This substitution eliminates mechanical measurement errors and provides more accurate digital measurements, directly resolving the contradiction between measurement precision and harmful effects.
Solution Approach 2:
The patent creates digital copies of the patient's eyes and optical parameters through imaging technology. These digital models allow for precise measurement and simulation of lens effects before actual lens fabrication, enabling accurate determination of pupillary distance and optical axis without the errors of conventional mechanical methods.
2Adaptability or versatility
If trial frames and conventional equipment are used for optometry, then the optometry procedure can be performed, but the optical angle design cannot fully predict actual optical correction parameters
Solution Approach 1:
The patent implements a feedback mechanism where the digital imaging system continuously monitors and measures the patient's actual eye movements, pupil positions, and optical parameters. This real-time feedback allows the system to adjust and refine the optical correction parameters to match the patient's actual visual behavior, significantly improving prediction accuracy and reliability.
Solution Approach 2:
The patent transitions from two-dimensional trial frame measurements to three-dimensional digital imaging and modeling. This dimensional enhancement allows for comprehensive capture of eye geometry, pupil position, and optical path in multiple dimensions, enabling much more accurate prediction of actual optical correction parameters.
3Productivity
If pupillary distance is measured with conventional instruments, then the measurement can be obtained quickly, but inaccuracies occur when vision is slightly deflected
Solution Approach 1:
The patent replaces slow, manual mechanical measurement instruments with automated digital imaging and image processing systems. The cameras capture eye images and the algorithms automatically calculate pupillary distance and optical parameters, achieving both high speed and high precision simultaneously by eliminating manual measurement errors.
Solution Approach 2:
The digital imaging system performs self-measurement by automatically capturing eye images, processing the images through algorithms, and calculating pupillary distance without requiring manual intervention. This self-service capability maintains measurement speed while dramatically improving accuracy through consistent, error-free automated measurement.

AI summary
A vision inspection and correction method, which uses an image adjustment software/device to separate the eyes of the inspected person on an independent display screen, and the visual mark seen by the same vision is designed to be misaligned; through the guidance and interaction of the inspector and the inspected person, the inspector can adjust the image operation to zoom in or out, shift, focus, diverge, and rotate, etc., so that the inspected person's binocular images can be clearly distinguished and adjusted. Then, the binocular images are aligned, and the inspector will implant the correction parameters during the image adjustment process into 3D projectors, VR (virtual reality), AR (augmented reality device), MR hybrid reality device and other equipment to adjust the binocular digital image parameters, so users have, or can provide to a lens maker, personalized adjustment for comfortable images of both eyes.
