2results about How to "Reduce repetitive work" patented technology

This invention discloses a method and system for modeling vehicle door structures, relating to the field of automotive design technology. The method includes: determining the large glass surface based on the glass boundary of the door window frame; calling a library of standard door cross-sections with predefined standard cross-sectional references based on the door structure; determining design cross-sectional references for each standard cross-section based on the door structure design parameters; adjusting the standard cross-sectional references to the design cross-sectional references to determine the design position of each cross-section; and generating a door structure model based on all determined cross-sectional positions. This invention achieves rapid and standardized modeling of vehicle door structures through parametric and automated cross-sectional reference alignment and positioning, reducing repetitive manual work, improving design efficiency and consistency, and enabling early verification and optimization of key designs such as hinge arrangement. The system includes corresponding functional modules to implement the method.
