Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If eyewear is mass-produced with generic designs, then manufacturing cost and productivity are improved, but fit accuracy and optical performance deteriorate
Solution Approach 1:
The system performs preliminary actions by capturing user facial measurements and optical parameters before the eyewear manufacturing process. A parametric model is pre-configured with adjustable parameters that can be customized based on user-specific data, enabling mass customization without sacrificing manufacturing efficiency.
Solution Approach 2:
The invention applies parameter changes by using a configurable parametric model where geometric parameters (frame size, shape, position) and optical parameters (lens power, focal points, segment positions) can be adjusted based on user-specific measurements. This allows customization of each eyewear unit while maintaining efficient manufacturing processes.
2Ease of operation
If traditional in-store eyewear selection is used, then users can try on physical products, but time consumption and selection complexity increase
Solution Approach 1:
The system creates a digital copy or virtual representation of the user's facial anatomy and optical characteristics. This digital model allows users to visualize and evaluate different eyewear options virtually, eliminating the need to physically try on multiple pairs in stores and significantly reducing selection time.
Solution Approach 2:
The parametric model serves multiple functions: it captures facial geometry, determines optimal frame positioning, calculates optical parameters, and generates visualizations. This multi-functional approach consolidates what would traditionally require multiple separate steps and physical interactions into a single digital process.
3Adaptability or versatility
If advanced multi-focal optics are ordered remotely, then customization capability is improved, but measurement accuracy and ordering complexity increase
Solution Approach 1:
The system incorporates feedback mechanisms where the parametric model is iteratively refined based on user-specific measurements and optical data. The model allows for adjustment and verification of measurements before finalizing the custom eyewear order, ensuring measurement precision while enabling remote customization of complex multi-focal optics.

AI summary
Systems and methods are disclosed for generating an eyewear frame and lens geometry that is customized to a user's anatomy and optimized for optical performance. One method includes receiving a configurable parametric model of a user-specific eyewear product comprising a frame portion and a lens portion, wherein geometric parameters of the configurable parametric model are based geometric features of a user's anatomy; receiving media data of a user, the media data including the user's response to visual cues; detecting the position of the user's eyes from the received media data; determining optical information of the user based on the detected position of the user's eyes; and generating an updated configurable parametric model by modifying the received configurable parametric model based on the determined optical information.
