Solution Approach 1:

The patent replaces manual mechanical design processes with a digital simulation system that uses computational models to predict fabric behavior. The simulation environment allows designers to explore design iterations digitally rather than physically, substituting manual iterative processes with automated computational analysis that maintains design flexibility while dramatically improving productivity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent implements preliminary digital simulation and prediction of fabric deformations before actual manufacturing. By performing virtual design iterations and predicting how different stitch structures will deform in advance, the system allows designers to explore multiple design options without physical prototyping, thereby maintaining adaptability while reducing time consumption and improving productivity.

Solution Approach 1:

The patent introduces a computational predictive model as an intermediary between the simple design process and accurate deformation measurement. This model acts as a mediator that takes basic design parameters as input and outputs precise predictions of fabric behavior, allowing designers to maintain simple design workflows while achieving high measurement precision through the intermediary simulation layer.

Inventive Principle:

Solution Approach 2:

The patent substitutes physical measurement and manual assessment of fabric deformations with computational simulation. By replacing the need for physical prototyping and manual measurement with a digital predictive model, the system maintains design process simplicity while dramatically improving the precision of deformation predictions through virtual analysis.

Solution Approach 1:

The patent creates virtual copies of the knitted fabric through computational simulation. Instead of repeatedly producing physical prototypes for validation, the system generates digital replicas that simulate fabric behavior and deformations. These virtual copies allow for reliable design validation through repeated virtual testing without the time loss and resource consumption associated with physical prototyping cycles.

Inventive Principle:

Solution Approach 2:

The patent performs preliminary validation through digital simulation before committing to physical production. By validating designs in the virtual environment first, the system ensures reliability of design decisions while avoiding the time-consuming cycle of multiple physical prototypes. The preliminary virtual validation reduces the need for subsequent physical testing iterations.

Solution Approach 1:

The patent implements a feedback mechanism where the computational predictive model provides information about expected deformations back to the design process. This feedback loop allows designers to adjust digital designs based on predicted physical behavior, enabling effective customization of complex structures while reducing fabrication challenges. The feedback from simulation to design creates a closed-loop system that bridges the gap between digital customization and physical manufacturing.

Inventive Principle:

Solution Approach 2:

The patent uses the computational predictive model as an intermediary between digital customization tools and physical fabrication. This intermediary translates digital design intentions into predictions of physical behavior, allowing designers to effectively customize complex structures by understanding how digital modifications will manifest physically. The intermediary reduces fabrication difficulties by providing advance knowledge of deformation behavior.

AI summary

Computer based systems and methods for designing and manufacturing consumer products, including knit footwear uppers, and the like. The system simulates deformations of knit structures and allows the user to control and visualize compensations in the structure(s) of the knitted component to better match between an intended knit design and the actual physical knitted component outcome. The system may modify a knit design of a knitted component to compensate for a predicted/estimated deformation behavior of the knitted component, for example, by duplicating one or more portions of a knit structure associated with the knit design.
