Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The traditional process of producing distressed denim is resource-intensive, time-consuming, and environmentally impactful, requiring significant water, chemicals, and energy to achieve the desired faded or worn look, while also being costly.
Innovation Solution
A system that uses a digital design tool to create and preview laser finishing patterns on denim, allowing for real-time editing and application of designs directly onto garments using a laser finishing machine, which burns the patterns and then undergoes a wash to achieve the desired appearance, reducing resource usage and processing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional water and chemical washing processes are used to create distressed denim, then the desired faded and worn appearance is achieved, but resource consumption (water, chemicals, energy) and environmental impact increase significantly
Solution Approach 1:
The patent replaces traditional mechanical and chemical washing processes with a laser-based system. The laser finishing machine uses optical energy to selectively remove or fade denim fabric in predetermined patterns, eliminating the need for water, chemicals, and extensive mechanical agitation while achieving the same distressed appearance效果
Solution Approach 2:
The patent changes the fundamental parameter of the finishing process from wet chemical processing to dry optical processing. By using laser energy with controllable parameters (power, speed, pattern), the system achieves precise control over the distressed appearance while eliminating resource consumption associated with traditional washing methods
2Manufacturing precision
If traditional multiple-step washing and distressing processes are used, then wear patterns are created, but processing time and production cost increase
Solution Approach 1:
The patent uses a digital design tool to create and preview laser finishing patterns before actual production. This preliminary digital prototyping allows for precise pattern design and optimization, ensuring accurate wear patterns are achieved in the first laser pass without requiring multiple iterative washing steps
Solution Approach 2:
The laser finishing machine performs multiple traditional washing steps in a single operation. The laser systematically treats the denim fabric according to predetermined digital patterns, achieving in one pass what traditionally required multiple sequential washing, distressing, and drying cycles
3Manufacturing precision
If physical samples are produced to preview designs before manufacturing, then design accuracy is confirmed, but resource consumption and time increase
Solution Approach 1:
The patent uses a digital design tool that creates a virtual 3D model of the garment and overlays the laser finishing pattern digitally. This digital copy or virtual prototype allows designers and manufacturers to preview the exact distressed appearance before production, eliminating the need to physically produce sample garments for approval
Solution Approach 2:
The system replaces physical sampling with digital visualization. The digital design tool renders how the laser pattern will appear on the 3D garment model, providing accurate design preview without any physical material consumption or time-intensive sample production and evaluation cycles
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 method enables the efficient production of distressed denim with reduced environmental impact and lower costs, while maintaining the aesthetic quality of traditional finishing techniques, by allowing for precise control over the finishing process and the ability to create multiple designs from a single fabric template.
Implementation Method 1
A laser will burn the pattern onto apparel
Data Source
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.
