Innovation Solution
A digital design tool and laser finishing machine system that allows users to create, edit, and preview three-dimensional designs on apparel before manufacturing, using lasers to burn patterns onto garments, reducing environmental impact and processing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional finishing techniques are used to produce jeans with wear patterns, then the desired faded and distressed appearance is achieved, but significant amounts of water and chemicals are consumed
Solution Approach 1:
The patent replaces traditional mechanical and chemical finishing techniques (stone washing, enzyme treatment, chemical bleaching) with a laser-based system. The laser mechanically ablates the denim fabric surface to create wear patterns, whiskers, combs, and distressed effects without requiring water or chemical agents, thereby eliminating the substance loss associated with traditional methods
Solution Approach 2:
The patent utilizes controlled changes in laser parameters (power, speed, pulse duration, wavelength) to achieve different wear pattern effects on denim. By adjusting these parameters, the system can produce various finishes including faded areas, distressed patterns, and worn-in appearances, replacing the need for multiple chemical treatments with a single controllable physical process
2Manufacturing precision
If traditional finishing processes are used to create wear patterns on jeans, then the desired style and appearance are achieved, but the processing time is extended
Solution Approach 1:
The patent employs a digital design tool that allows users to create, edit, and preview wear patterns on a computer before the actual laser finishing process. This preliminary digital prototyping eliminates the need for time-consuming physical test runs and adjustments, enabling the laser system to directly execute the finalized design pattern without iterative processing
Solution Approach 2:
The laser system performs wear pattern creation in a single rapid pass compared to traditional methods that require sequential mechanical processes (stone washing, brushing, chemical treatment, rinsing, drying). The laser directly ablates the fabric according to the digital pattern, eliminating multiple time-consuming processing stages while maintaining appearance quality
3Manufacturing precision
If traditional finishing techniques are used to produce jeans with wear patterns, then the desired distressed look is achieved, but the processing cost increases
Solution Approach 1:
The patent replaces expensive traditional finishing infrastructure (chemical treatment plants, washing machines, drying facilities, multiple processing stations) with a laser system that requires minimal infrastructure. The laser generator and digital design tool eliminate the need for large volumes of water, chemical storage and handling systems, and extensive mechanical processing equipment, thereby reducing capital and operational costs
Solution Approach 2:
The laser system serves multiple functions that traditionally required separate processes: creating wear patterns, distressed effects, faded areas, and surface texturing all in a single operation. This multi-functionality consolidates multiple costly processing steps into one unified system, reducing overall manufacturing cost while maintaining the desired appearance quality
4Loss of substance
If a digital design tool is used to create and preview patterns before laser finishing, then resource usage is minimized, but the device complexity increases
Solution Approach 1:
The patent uses a digital design tool that creates a virtual copy or representation of the wear pattern on the denim garment before actual laser processing. This digital model allows complete pattern design, editing, and previewing without consuming any physical resources (water, chemicals, fabric). The digital copy enables full pattern development and approval before the laser executes the actual finishing, eliminating resource waste from trial and error

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.
