Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The apparel industry faces challenges in producing jeans with desired wear patterns, as traditional methods are resource-intensive, time-consuming, and environmentally costly, requiring significant water and chemical usage.
Innovation Solution
A method using a digital design tool that generates three-dimensional photorealistic previews of garments with customizable wear patterns, allowing users to select finishing patterns and combine them with digital input files for laser finishing, which applies wear patterns directly onto the fabric using a laser, reducing resource consumption and processing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional finishing techniques are used to produce wear patterns on jeans, then the desired aesthetic quality and wear patterns are achieved, but water and chemical usage increases significantly
Solution Approach 1:
The patent replaces traditional mechanical and chemical finishing systems (stone washing, enzyme treatment, bleaching) with a laser-based system. The laser precisely removes fabric material to create wear patterns without requiring water or chemicals, directly addressing the contradiction between achieving quality wear patterns and reducing substance loss.
Solution Approach 2:
The patent changes the fundamental parameter of the finishing process from wet chemical treatment to dry laser ablation. By using laser energy instead of chemical agents, the process achieves the same aesthetic effect (wear patterns) while eliminating water and chemical consumption, resolving the contradiction between manufacturing precision and substance loss.
2Manufacturing precision
If traditional finishing processes are used to create wear patterns, then the desired appearance is achieved, but processing time increases
Solution Approach 1:
The laser system replaces multi-step mechanical finishing processes (stone washing, tumbling, chemical treatment, drying) with a single-pass laser ablation process. This substitution dramatically reduces processing time while maintaining or improving wear pattern appearance quality.
Solution Approach 2:
The patent uses digital design tools to create precise wear pattern templates before the actual laser finishing process. This preliminary digital planning allows the laser to directly trace and create the desired wear patterns in one pass, eliminating the need for multiple iterative finishing steps and reducing overall processing time.
3Manufacturing precision
If traditional finishing methods are used to produce jeans with wear patterns, then the desired style is achieved, but processing costs increase
Solution Approach 1:
The patent replaces expensive traditional finishing methods (which require chemicals, water, energy for drying, and multiple processing steps) with a laser system that uses only electrical energy. The elimination of chemical and water consumption, along with reduced processing time, directly lowers manufacturing costs while maintaining wear pattern style quality.
Solution Approach 2:
By changing from chemical-based finishing to laser-based finishing, the patent eliminates costs associated with chemical purchases, water treatment, and extended processing time. The laser system's precision also reduces material waste and rework, further decreasing overall manufacturing costs while achieving the desired wear pattern style.
4Manufacturing precision
If traditional finishing techniques are used to create wear patterns, then the desired aesthetic effect is achieved, but environmental impact worsens
Solution Approach 1:
The laser system replaces chemical-based finishing processes with a dry, clean laser ablation process. This substitution eliminates harmful chemical discharges, water pollution, and associated environmental contamination, achieving the same wear pattern aesthetic quality without generating harmful environmental factors.
Solution Approach 2:
By transitioning from wet chemical finishing to dry laser finishing, the patent eliminates the generation of chemical waste, sewage, and air pollution associated with traditional methods. The laser process produces minimal waste (mainly vaporized fabric material) and no harmful chemical byproducts, resolving the contradiction between aesthetic quality and environmental impact.

Data Source
AI summary
A manufacturing flow of apparel such as jeans uses a laser to finish the products. The products are designed using a digital design tool, where photorealistic previews are generated in three dimensions and two dimensions. Imagery of the products are sent to retailers where customers can order the products, such as online orders. Imagery of the products are sent to factories where the products are finished. Based on the imagery, the factories make adjustments to the processes as needed so that the actual products will have an appearance as in the received imagery. As orders are received by the retailers, the factories can manufacture the desired products on demand, and the products can be delivered to customers.
