Solution Overview
Problem
The traditional process of producing distressed denim products is resource-intensive, time-consuming, and environmentally impactful, requiring significant water and chemical usage, which necessitates a more efficient and sustainable method for achieving faded or worn blue jeans looks.
Innovation Solution
A system utilizing software and lasers to create and preview designs for apparel, allowing for real-time modification and application of wear patterns on jeans, which uses indigo ring-dyed cotton yarn and varies laser parameters to achieve desired shades and patterns, reducing material removal and chemical usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional water and chemical finishing processes are used to create distressed denim, then the desired faded and worn appearance is achieved, but significant water and chemical resources are consumed
Solution Approach 1:
The patent replaces traditional mechanical and chemical finishing processes (water washing, chemical bleaching, pumice stone abrasion) with a laser-based system. The laser delivers precise energy to remove indigo dye from denim fabric, creating distressed patterns without requiring large amounts of water or chemicals. This substitution of mechanical/chemical systems with an energy-based laser system directly addresses the resource consumption problem while maintaining appearance quality.
Solution Approach 2:
The patent utilizes parameter changes in the laser system (power, pulse duration, scanning speed, wavelength) to control the degree of indigo removal and create various distressed effects. By adjusting these parameters, the system can achieve different levels of fading and distressing on denim fabric without changing the fundamental process, allowing precise control over the finished appearance while maintaining low resource consumption.
2Adaptability or versatility
If traditional multiple-step finishing processes are used to create wear patterns, then diverse distressed looks are achieved, but processing time is extended
Solution Approach 1:
The laser finishing system serves multiple functions that were previously required separate processes: it can create fading, distressing, whiskers, honeycombs, and other wear patterns all through laser energy application. The system's versatility comes from its ability to manipulate the laser parameters and scanning patterns to produce various distressed effects on denim, consolidating multiple traditional finishing steps into a single integrated process.
Solution Approach 2:
The system applies preliminary laser treatment to create the distressed appearance directly on the denim fabric during the finishing stage, rather than requiring multiple sequential processes. By pre-planning the laser path and parameters based on the desired wear pattern, the system can achieve diverse distressed looks in a single pass, reducing the number of processing steps and overall processing time.
3Manufacturing precision
If traditional chemical bleaching and oxidation processes are used to fade denim, then the desired light areas are achieved, but environmental impact increases
Solution Approach 1:
The patent replaces chemical bleaching and oxidation processes with laser energy application. Instead of using chemical agents to remove or alter the indigo dye, the laser directly heats and vaporizes the dye molecules from the denim fabric surface. This substitution eliminates the need for chemical waste disposal and reduces environmental pollution while maintaining precise control over the fading appearance.
Solution Approach 2:
The patent converts the potentially harmful concentrated laser energy into a beneficial finishing process. By carefully controlling the laser parameters, the high-energy beam selectively removes indigo dye without damaging the denim fabric structure. The laser energy, which could be considered harmful in excessive amounts, is precisely controlled to achieve the desired fading effect while minimizing any negative impacts on the fabric or environment.

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. Users may collaborate while designing the apparel and designate what items should belong in specific collections. Users may also use an assortment builder tool to search a database of products according to one or more search parameters to select a garment with a finishing pattern.
