Solution Overview
Problem
The traditional process of producing jeans with wear patterns is resource-intensive, time-consuming, and environmentally costly, requiring significant water and chemical usage.
Innovation Solution
A software and laser-based system that allows users to create, preview, and apply wear patterns onto jeans, reducing the need for extensive water and chemical usage by directly burning patterns onto the fabric using a laser.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional water and chemical-based finishing techniques are used to create wear patterns on jeans, then the desired faded and distressed appearance is achieved, but significant amounts of water and chemicals are consumed, increasing environmental impact and processing costs
Solution Approach 1:
The patent replaces traditional mechanical and chemical finishing processes (water washing, chemical bleaching, enzyme treatment) with a laser-based system. The laser directly ablates and heats the denim fabric to create wear patterns, fading effects, and distressed appearances without requiring large volumes of water or harsh chemicals, thereby resolving the contradiction between achieving desired appearance and reducing substance consumption
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 degrees of fabric removal, heating, and color change, producing the desired faded and distressed appearance while maintaining minimal resource consumption
2Manufacturing precision
If traditional multi-step finishing processes are used to create distressed denim, then comprehensive wear patterns are achieved, but processing time is extended and production efficiency is reduced
Solution Approach 1:
The patent combines multiple traditional finishing steps (washing, bleaching, enzyme treatment, mechanical abrasion) into a single laser processing operation. The laser simultaneously performs fabric removal, heating, and color modification in one pass, eliminating the need for sequential processing steps and significantly reducing total processing time while maintaining comprehensive wear pattern effects
Solution Approach 2:
The laser processing system operates continuously across the denim fabric surface, maintaining constant energy delivery and material transformation. The laser beam scans continuously across the fabric without interruption, ensuring uniform and complete wear pattern development in a single continuous operation, thereby maximizing productivity while achieving comprehensive finishing effects
3Manufacturing precision
If traditional finishing methods are used to create wear patterns, then the desired aesthetic effect is achieved, but processing costs and environmental impact increase
Solution Approach 1:
The patent replaces environmentally harmful chemical processes (bleaching agents, oxidizers, enzymes) and water-intensive washing operations with a laser-based thermal and ablation process. The laser directly modifies the fabric through controlled heating and material removal, eliminating the need for harmful chemicals and reducing water consumption, thereby achieving the desired aesthetic effect while minimizing environmental impact
Solution Approach 2:
The patent converts the laser's high-energy light into controlled thermal effects that benefit the finishing process. The laser energy is absorbed by the denim fabric, converting optical energy to heat, which then produces the desired fading, browning, and distressing effects. This conversion allows precise control over the aesthetic outcome while avoiding the uncontrolled environmental harm associated with traditional chemical discharge and water pollution
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach reduces environmental impact, processing time, and costs while maintaining the desired look and style of traditional finishing techniques, enabling efficient and sustainable production of jeans with customizable wear patterns.
Implementation Method 1
The laser removes a selected amount of the surface of the indigo dyed yarn (e.g., blue color) to reveal a lighter color (e.g., white color) of the inner core of the ring-dyed yarn.
Implementation Method 2
There can be additional finishing II, which may include tinting, softening, or fixing. For example, the laser can be used to brown or slightly burn portions of the apparel product, which can be desirable in some applications.

AI summary
A tool allows a user to create new designs for apparel and preview these designs 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.
