Vector Knitting Data Conflict Detection in Flat Knit Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for designing knitted fabrics on flat knitting machines face limitations in displaying and resolving conflicts between pattern and basic pattern data without converting cutting data into needle-related knitting data, limiting flexibility and accuracy in shaping the fabric.
Innovation Solution
A method that uses vectorial cutting data to position cuts on a basic pattern in symbolic representation, allowing for parallel editing of cutting and knitting data without conversion, enabling immediate conflict detection and resolution, and maintaining data integrity by separating data levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cutting data are converted into needle-related knitting data before display, then the knitting data can be integrated with the basic pattern, but the flexibility to change cutting data is lost and conflicts cannot be detected early
Solution Approach 1:
The system separates cutting data and knitting data into distinct data levels, allowing independent processing and display. Cutting data remains in vector format while knitting data is displayed in symbolic representation, enabling flexible modification of cutting data without affecting knitting data integrity.
Solution Approach 2:
The display device acts as an intermediary that shows both cutting data and knitting data simultaneously without converting cutting data into knitting data. This allows users to detect conflicts between pattern and basic pattern before finalizing the design, while maintaining data flexibility.
2Stability of the object's composition
If cutting data are converted into needle-related knitting data early in the process, then the data can be firmly integrated, but time is lost and conflicts are detected too late
Solution Approach 1:
The system performs preliminary display of both cutting data and knitting data in symbolic representation before conversion to machine control data. This allows early detection and resolution of conflicts between pattern and basic pattern, saving time in the later stages of design.
Solution Approach 2:
The display device provides immediate visual feedback showing both cutting data and knitting data together in symbolic representation. Users can see conflicts between pattern and basic pattern immediately and make adjustments before finalizing the design, reducing iterative revisions.
3Adaptability or versatility
If cutting data are displayed without conversion to needle-related knitting data, then data flexibility is maintained, but direct integration with basic pattern is difficult
Solution Approach 1:
The system changes the representation parameter of knitting data to symbolic form that can be displayed alongside vector-based cutting data. This allows both data types to be visualized and compared in the same space without conversion, maintaining flexibility while enabling integration.

AI summary
The method involves loading a section (6) of a profiled knitted fabric from memory of a drafting device. The section of the knitted fabric is positioned on a base pattern (1) in a vector symbol representation, and sectional data with knitting data of the base pattern without converting knitting-related sectional data into needle-related knitting data. The section of the knitted fabric is adjusted at the base pattern if machine controlled data is created for section positioning. A conflict is displayed between the sectional data and knitting data of the base pattern. An independent claim is also included for a device for designing a profiled knitted fabric on a flat knitting machine by a drafting device, comprising a storage unit.
