Solution Overview
Problem
The traditional process of producing distressed denim is resource-intensive, time-consuming, and environmentally costly, requiring significant water and chemical usage, which is unsustainable and inefficient.
Innovation Solution
A software and laser-based system that allows users to create, preview, and apply wear patterns on jeans, enabling real-time modifications and simulations of designs before actual laser finishing, reducing the need for extensive water and chemical use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional water and chemical-based finishing techniques are used, then the desired faded or worn appearance is achieved, but resource consumption (water and chemicals) increases significantly
Solution Approach 1:
The patent replaces chemical and water-based finishing processes with a laser-based mechanical/thermal system. The laser selectively removes fabric material through ablation to create distressed patterns, eliminating the need for large quantities of water and chemicals while achieving the desired aesthetic effect.
Solution Approach 2:
The patent changes the fundamental parameter of the finishing process from chemical concentration and water volume to laser power, speed, and pattern parameters. By controlling laser intensity and movement, the system achieves varied distress effects without consuming physical chemicals or water.
2Measurement precision
If traditional multi-step finishing processes are used, then wear patterns are achieved, but processing time increases
Solution Approach 1:
The patent uses computer software to design and simulate the distress patterns before actual laser application. This preliminary digital planning allows for optimization of the laser path and parameters, reducing the number of passes and adjustments needed during actual processing, thereby reducing total processing time.
Solution Approach 2:
The patent replaces multiple sequential chemical treatment steps with a single laser processing step. The laser can create all desired distress effects—including fading, holes, and wear patterns—in one continuous process, eliminating the need for multiple separate treatment stages.
3Measurement precision
If traditional finishing methods are used, then distressed appearance is achieved, but environmental impact worsens due to chemical waste
Solution Approach 1:
The patent substitutes chemical-based finishing with laser-based finishing, which produces minimal waste and no harmful chemical emissions. The laser process creates dust and heat but eliminates the need for chemical baths, rinsing water, and associated wastewater treatment, thereby reducing environmental pollution.
Solution Approach 2:
The patent converts the laser's thermal energy, which could be considered a harmful effect, into a beneficial tool for precise fabric modification. The controlled heat from the laser achieves the distressed look without introducing chemical pollutants into the environment.
4Measurement precision
If traditional finishing processes are used, then wear patterns are created, but processing cost increases due to resource intensity
Solution Approach 1:
The patent replaces resource-intensive chemical processing with laser processing, which reduces costs associated with purchasing, storing, and disposing of chemicals and water. Although laser equipment has high initial cost, the operational costs are lower due to eliminated chemical and water consumption.
Solution Approach 2:
The patent changes the cost structure from variable costs (chemicals and water per unit processed) to fixed costs (laser equipment depreciation). This parameter change reduces ongoing operational expenses and makes the manufacturing process more cost-effective at scale.

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.
