Knitted Fabric Simulation with Compressed Symbol Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for designing knitted products on knitting or warp-knitting machines are inefficient, requiring multiple steps and view changes to check for input errors and pattern distortions, leading to delayed detection and correction of faults.
Innovation Solution
A method that allows immediate recognition of pattern changes in a simulated knitted fabric view, enabling simultaneous display of distortions and stitch accumulations without the need for processing changes, using a compressed symbolic representation that updates only the affected area, utilizing all computer cores for faster pattern creation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If compressed symbol representation is used for pattern creation, then input efficiency is improved, but pattern distortions and errors cannot be detected until after conversion and simulation
Solution Approach 1:
The display area is divided into two separate views: a compressed symbol representation view for efficient input and an uncompressed knitted fabric simulation view for error detection. This segmentation allows the system to maintain both input efficiency and error detection capability simultaneously by presenting different representations in parallel.
Solution Approach 2:
The system merges the compressed symbol representation and the uncompressed knitted fabric simulation into a single integrated display interface. This combining allows the operator to access both representations without switching between separate applications or views, enabling simultaneous input efficiency and error detection.
2Reliability
If uncompressed symbol representation is used, then error detection is improved, but input efficiency decreases
Solution Approach 1:
The system segments the representation modes by providing both compressed and uncompressed views simultaneously in separate display areas. This allows the operator to use compressed symbols for rapid input while having immediate access to the uncompressed simulation for error detection, eliminating the need to choose one mode over the other.
Solution Approach 2:
The system performs the computationally intensive conversion to uncompressed representation partially by only converting and displaying the currently visible or recently edited portion of the pattern. This reduces the processing burden while still providing error detection capability for the relevant areas.
3Measurement precision
If full pattern simulation is performed, then realistic representation is improved, but computing time and resources increase
Solution Approach 1:
The simulation is segmented to process only the currently visible or recently edited portion of the pattern rather than the entire pattern. This allows the system to provide realistic simulation feedback immediately for the relevant area while avoiding the computational burden of processing the complete pattern.
Solution Approach 2:
The system performs preliminary conversion of the compressed symbol representation to uncompressed representation in advance, before the user needs to view or edit that portion of the pattern. This preprocessing allows immediate display of realistic simulation results when the user navigates to or edits that area, without requiring time-consuming conversion at the moment of viewing.

AI summary
The method involves compressing sample view (1) of knitted product into a symbolic representation, and displaying the symbolic representation on a display device. A knitted product simulation (2) is displayed in display device during editing of sample view of knitted product, such that both knitted product simulation and sample view of knitted product are viewed simultaneously in the display device. An independent claim is included for device for designing on rope or knitting machine stitched product.
