Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional manual measurement devices and expert examination are used to determine lens prescription, then measurement precision can be achieved, but the process becomes complicated and time-consuming
Solution Approach 1:
The patent replaces manual mechanical measurement devices with an image processing system that captures eye movement patterns through camera imaging. The system automatically analyzes retinal vessel images and eye motion data to determine lens prescription, eliminating the need for complex manual instruments and expert manual measurement procedures.
Solution Approach 2:
The patent creates a virtual copy of the eye examination process by capturing images of the retina and eye movements, then processing these digital copies to determine lens prescription. This digital copying approach allows for rapid, repeatable measurements without the time-consuming physical manipulation required in conventional methods.
2Ease of manufacture
If previously manufactured standard lenses are selected based on general eye examination, then the selection process is simplified, but lens adaptability to individual wearer needs deteriorates
Solution Approach 1:
The patent applies local quality by tailoring lens characteristics to specific individual needs based on captured eye movement patterns and retinal images. Instead of using standard lenses for all wearers, the system determines customized lens parameters (power, astigmatism, progressive zones) specific to each wearer's visual requirements and eye behavior.
Solution Approach 2:
The patent changes lens parameters dynamically based on measured eye movement data and retinal vessel characteristics. The system adjusts lens power, astigmatism correction, and progressive addition values according to the specific wearer's anatomical and functional eye characteristics, enabling customized lens design rather than reliance on pre-manufactured standard lenses.
3Manufacturing precision
If complex functional lenses like progressive and multi-focal lenses are manufactured, then vision correction precision is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent performs preliminary action by capturing and analyzing eye movement patterns and retinal images before lens manufacturing begins. This advance data collection and analysis allows the system to pre-determine the exact lens parameters needed, enabling precise manufacturing of complex functional lenses without requiring trial-and-error adjustments or multiple measurements during the manufacturing process.

AI summary
In a method of simulating a lens using augmented reality, a user who desires to purchase a vision correction product may wear lenses precisely corrected using a computer device through a virtual experience, and inconvenience of frequently replacing various lenses when taking an eye examination is considerably mitigated. An effect of wearing a variety of vision correction products in a short time period can be experienced, and it is expected to be able to select an optimized custom-tailored vision correction product. Particularly, in manufacturing a functional lens which has complicated manufacturing steps and requires a precise examination, such as a progressive multi-focal lens, a coating lens, a color lens, a myopia progress suppression lens, an eye fatigue relieve lens or the like, it is expected that a precise product can be manufactured, and manufacturing time can be greatly reduced.
