Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If actual fabric products are produced to provide virtual graphic images, then the visual accuracy of fabric products is improved, but the manufacturing cost and time are increased
Solution Approach 1:
The patent uses 2D fabric images as copies to generate 3D virtual fabric products, eliminating the need to produce actual physical samples. The system processes 2D images through correction and 3D modeling to create virtual representations that maintain visual accuracy without requiring physical manufacturing
Solution Approach 2:
The patent replaces the mechanical process of physical fabric production with a computational image processing system. Instead of manually creating and photographing physical fabric samples, the system uses automated 2D image correction and 3D rendering algorithms to generate virtual fabric product images
2Measurement precision
If expert software operation is used to provide virtual graphic images, then the quality of virtual fabric images is improved, but the ease of operation is deteriorated
Solution Approach 1:
The system performs automated 2D image correction and 3D modeling without requiring expert user intervention. The correction unit automatically adjusts 2D fabric images for lighting, shadow, and distortion, and the 3D modeling unit automatically generates 3D virtual products, making the process accessible to general users rather than requiring specialized software expertise
Solution Approach 2:
The patent divides the complex image processing task into separate functional units: a correction unit that handles 2D image adjustments and a 3D modeling unit that generates 3D virtual products. This segmentation allows each unit to specialize in specific tasks, improving overall image quality while simplifying the user interface
3Productivity
If 2D fabric images are directly converted to 3D images without correction, then the processing speed is improved, but the manufacturing precision is deteriorated
Solution Approach 1:
The system performs preliminary correction of 2D fabric images before 3D modeling, addressing issues like lighting, shadow, and distortion in advance. This preliminary action ensures that the input images are optimized for 3D conversion, maintaining high modeling accuracy without requiring complex real-time processing during the 3D generation phase

AI summary
A three-dimensional (3D) modeling method may include: receiving an image of a fabric and information associated with the fabric from a user; performing correction on the image of the fabric; and generating 3D images of a plurality of fabric products using the fabric based on the corrected image of the fabric and the received information associated with the fabric.
