Modular Tool for Self-Folding Knit Fabric Design

The patent applies preliminary action by performing virtual simulations and computational modeling before actual textile production. The system calculates edge rolling and folding behaviors using mathematical models that predict fabric deformation based on stitch patterns, allowing designers to optimize mechanical deformation behaviors in silico before committing to physical production, thereby eliminating trial-and-error cycles and significantly improving productivity while maintaining manufacturing precision.

The patent applies the extraction principle by isolating and focusing only on the critical parameters that govern edge rolling and folding behaviors in knit fabrics. Rather than incorporating all possible yarn properties and fabrication variables, the model extracts and utilizes specifically the stitch pattern geometry, knit/purl stitch distributions, and basic fabric mechanical properties. This selective approach maintains measurement precision for the target deformation behaviors while significantly reducing device complexity and making the modeling tool more practical and accessible.
