Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The traditional methods for producing distressed denim products are resource-intensive, time-consuming, and environmentally impactful, requiring significant water and chemical usage, whereas there is a demand for a more efficient and sustainable process to achieve a faded or worn blue jeans look.
Innovation Solution
A software and laser-based system that allows users to create, preview, and apply wear patterns onto apparel, specifically using a laser to remove indigo-dyed cotton yarn selectively, thereby replicating the appearance of traditional distressing techniques while reducing environmental impact and processing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional water and chemical-based finishing techniques are used to produce distressed denim, then the desired faded or worn appearance is achieved, but significant water and chemical resources are consumed and environmental impact increases
Solution Approach 1:
The patent replaces chemical and water-based finishing processes with a laser-based mechanical/thermal system. The laser selectively removes indigo dye from cotton yarn to create distressed patterns, eliminating the need for traditional water baths, chemicals, and extensive washing processes while achieving the same aesthetic effect.
Solution Approach 2:
The patent changes the fundamental parameter of the finishing process from chemical concentration and water flow to laser power, pulse duration, and scanning speed. By controlling laser parameters such as power level (e.g., 50-100 watts), pulse width (e.g., 10-100 microseconds), and scanning speed, the system achieves precise control over the distressed appearance without consuming water or chemicals.
2Manufacturing precision
If traditional multi-step finishing processes are used to create wear patterns, then the desired aesthetic is achieved, but processing time increases
Solution Approach 1:
The patent applies preliminary digital design and simulation before the actual laser finishing process. Users can design wear patterns digitally, simulate the laser effects on 3D garment models, and preview the final appearance before committing to production. This preliminary action prevents rework and optimizes the actual laser processing time.
Solution Approach 2:
The laser finishing process operates continuously without the interruptions inherent in traditional multi-step processes. The laser can continuously scan and treat the garment surface according to the digital pattern, eliminating the need for multiple separate steps such as applying chemicals, waiting for reaction, rinsing, drying, and repeating for different areas.
3Manufacturing precision
If traditional finishing methods are used to achieve distressed look, then the aesthetic is achieved, but processing costs increase
Solution Approach 1:
The patent recovers and reuses the laser system for multiple garments and different designs without consuming expensive chemicals or large amounts of water that would need to be treated and disposed of. The laser system can be quickly reprogrammed for different patterns, and the only consumable is electricity, which is far cheaper than the combination of chemicals, water, and energy required for traditional finishing.

AI summary
A system 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. The user's preview may be based upon a two-dimensional image of a wear pattern in a laser input file and, from a set of two-dimensional images of a base garment, create a three-dimensional view of the base garment with the wear pattern.
