AI Technical Summary

Technical Problem

In existing technologies, the material differences and non-deformability of plastic head molds and digital head molds in eyeglass design make it impossible to accurately assess the fit and pressure between the eyeglasses and the human head, thus affecting the user experience.

Method used

Using the finite element method, an interaction analysis is conducted on the expected contact area between the glasses model and the human head model to generate a pressure cloud map. Based on the pressure cloud map, the interaction relationship between the glasses and the head model is generated, and finally, the glasses are produced.

Benefits of technology

It improves the fit and pressure between the glasses and the head, enhancing the user experience and making it more ergonomically designed compared to glasses produced using conventional digital models.

Abstract

The application provides a spectacle production method and system based on finite element analysis. First, the interaction between the spectacle model and the expected contact area in the human head model is analyzed by finite element analysis to obtain a first pressure cloud chart of the human head. Then, the interaction relationship between the spectacle and the head model is generated according to the pressure cloud chart. Finally, the spectacle is produced according to the interaction relationship. The application is based on the interaction between the spectacle and the head shape by finite element analysis, and thus the deformation of the spectacle and the head shape when worn and the pressure on each part of the head can be known during production. The fit and compression of the actual spectacle and the human head can be better understood, and the spectacle produced by using the conventional digital model has a better user experience effect.
