Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing weaving machines are limited to producing plain fabrics and lack the capability for automated 3D surface weaving, while knitting technologies face material limitations due to their isotropic and poor mechanical properties under tensile force.
Innovation Solution
A control command generation method and system that rebuilds a 3D object into a surface mesh, converts it into readable weaving information, and generates commands for a 3D surface weaving system, utilizing a jacquard device, weaving device, and roller matrix to automate 3D surface weaving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional weaving machines are used to produce plain fabric, then the manufacturing process is simple and reliable, but the ability to create 3D surface weaving is lost
Solution Approach 1:
The control command generation system is divided into three distinct modules: (1) a 3D object rebuilding module that converts 3D models into surface meshes, (2) a conversion module that transforms surface meshes into readable weaving information, and (3) a control command generation module that produces instructions for the weaving system. This segmentation allows each module to specialize in specific tasks, making the overall complex system more manageable and easier to implement.
Solution Approach 2:
The patent introduces an intermediary control command generation system that acts as a mediator between the 3D object design and the physical weaving process. This intermediary system includes the 3D rebuilding module, conversion module, and control command generation module, which together translate complex 3D designs into executable weaving commands, bridging the gap between design and manufacturing.
2Shape
If knitting technology is used to achieve 3D forming, then 3D surface creation is possible, but the material must be soft and elastic with poor mechanical properties under tensile force
Solution Approach 1:
The patent changes the fundamental parameter of how 3D surfaces are created by switching from knitting (which requires soft, elastic materials) to weaving (which uses rigid, strong materials). By controlling the weaving process to create 3D surfaces, the system achieves both 3D formation and superior mechanical strength, as weaving allows for tighter, more durable structures that can withstand tensile forces.
3Extent of automation
If hand-woven 3D surface products are made, then 3D surface weaving is achieved, but the production process cannot be automated and industrialized
Solution Approach 1:
The patent replaces the manual mechanical weaving process with an automated control system. The control command generation system automatically processes 3D models, converts them into weaving instructions, and controls the weaving machine, eliminating the need for manual operation and enabling industrialization of 3D surface weaving.

AI summary
The present application relates to control command generation methods and systems for three-dimensional surface weaving. The control command generation method comprises the steps of: rebuilding a desired three-dimensional object into a three-dimensional surface mesh; converting the three-dimensional surface mesh into readable weaving information; and generating control commands from the readable weaving information to instruct a three-dimensional surface weaving system. The control command generation method generally comprises a pipeline of software including the mesh processing, weaving map extraction and command generation. The control command generation method can enable three-dimensional surface weaving function.
