Engineering Contradiction Analysis
1Area of moving object
If traditional optical lens design methods are used, then the lens can be manufactured with standard optical properties, but the zone of comfortable gaze directions is restricted
Solution Approach 1:
The patent applies local quality by optimizing optical criteria specifically in the zone of comfortable gaze directions rather than uniformly across the entire lens. The method identifies a target zone around the gazing direction and applies targeted optimization to maximize this specific area while maintaining acceptable optical properties elsewhere, thereby increasing the zone of comfortable gaze without compromising overall manufacturing feasibility
Solution Approach 2:
The patent utilizes parameter changes by systematically adjusting optical design parameters (such as surface curvatures, aspheric coefficients, and lens geometry) to optimize the zone of comfortable gaze directions. The computer-implemented method iteratively modifies these parameters to maximize the target zone while constraining optical criteria deviations within acceptable thresholds, enabling precise control over the lens performance in the desired gaze zone
2Area of moving object
If the optical lens is optimized for a specific gazing direction, then the zone of comfortable gaze directions is maximized, but the complexity of the design process increases
Solution Approach 1:
The patent applies self-service by implementing an automated computer-implemented method that autonomously performs the complex optimization process. The system automatically identifies the gazing direction, defines the target zone, selects appropriate optical criteria, and iteratively adjusts design parameters without requiring manual intervention at each step, thereby managing design complexity through automation while achieving maximized comfortable gaze zones
Solution Approach 2:
The patent utilizes feedback mechanisms by continuously evaluating optical criteria during the optimization process and adjusting design parameters based on performance measurements. The method calculates deviations from target optical criteria in the zone of comfortable gaze directions and uses this feedback to iteratively refine the lens design, ensuring optimal performance while systematically managing the complexity of the design process

AI summary
Method implemented by computer means for determining an optical lens adapted for a wearer and optimized for at least a given optical criterion having a target value around a specific gaze direction, the method comprises: obtaining an initial optical lens having in a specific gaze direction a prescription of the wearer in given wearing condition; determining an intermediate optical lens by optimizing, using an optimization function, the initial optical lens so that the difference between the value of the at least given optical criterion of said intermediate optical lens and the target value of gaze directions around the specific gaze direction is smaller than or equal to a threshold value, determining the optical lens by optimizing the intermediate optical lens so as to obtain the largest zone of gaze directions around the specific gaze direction for which the difference between the value of the at least given optical criterion and the target value around the specific gaze direction is smaller than or equal to the threshold value.
