3D Garment Visualization for Laser Finishing Pattern Preview
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The traditional process of producing jeans with wear patterns is resource-intensive, time-consuming, and costly, using significant amounts of water and chemicals, and lacks an efficient method for creating and previewing patterns before laser finishing.
Innovation Solution
A digital design tool generates three-dimensional photorealistic visualizations of finishing patterns, allowing users to create, edit, and preview designs in real time, which are then implemented by a laser finishing machine to produce desired wear patterns on garments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional water and chemical finishing processes are used, then wear patterns can be achieved, but resource consumption and environmental impact increase significantly
Solution Approach 1:
The patent replaces traditional mechanical and chemical finishing processes (water washing, chemical treatments, pumice stone abrasion) with a laser-based system. The laser beam directly ablates and heats the denim fabric to create wear patterns, whiskers, combs, and other distress effects without requiring water, chemicals, or physical abrasives, thereby eliminating resource consumption and environmental pollution associated with traditional methods
Solution Approach 2:
The patent utilizes controlled changes in laser parameters (power, pulse duration, scanning speed, wavelength) to achieve different wear pattern effects on denim. By adjusting these parameters, the laser can create various finishes including faded areas, distressed patterns, and textured effects, replacing the need for multiple chemical treatments and physical processes with a single controllable energy input
2Adaptability or versatility
If traditional multi-step finishing processes are used, then various wear patterns can be produced, but processing time and costs increase
Solution Approach 1:
The patent employs a single laser finishing machine that can produce multiple types of wear patterns (whiskers, combs, honeycombs, distressed areas, faded effects) through software control and pattern selection. This multi-functional capability eliminates the need for separate processing steps for different wear patterns, allowing all finishes to be applied in one continuous operation, thereby increasing productivity while maintaining pattern variety
Solution Approach 2:
The patent uses computer-generated design files and digital pattern templates that predefine the exact wear patterns to be created. Before the laser finishing process begins, the desired wear patterns are digitally designed and programmed into the system, allowing for precise reproduction of various styles without requiring manual pattern creation or multiple trial processes, thus reducing processing time while maintaining design flexibility
3Loss of information
If physical samples are created for each design variation, then design preview is possible, but time and resource consumption increase
Solution Approach 1:
The patent uses digital imaging and computer-generated visualizations to create virtual copies of the finished garment with wear patterns applied. Instead of producing physical samples, the system generates digital images that accurately represent the appearance of the laser-finished product, allowing designers and customers to preview designs, make adjustments, and approve patterns before actual laser processing begins, thereby eliminating time-consuming sample production while maintaining visualization accuracy

AI summary
A tool allows a user to create new designs for apparel and preview these designs in three dimensions before manufacture. Software and lasers are used in finishing apparel to produce a desired wear pattern or other design. Based on a laser input file with a pattern, a laser will burn the pattern onto apparel. With the tool, the user will be able to create, make changes, and view images of a design, in real time, before burning by a laser. Input to the tool includes fabric template images, laser input files, and damage input. The tool allows adding of tinting and adjusting of intensity and bright point. The user can also move, rotate, scale, and warp the image input.
