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, while also being costly.
Innovation Solution
A system that uses software and lasers to create and preview wear patterns on apparel, allowing for real-time modification and application of designs directly onto the fabric, reducing the need for traditional finishing techniques like dry abrasion and wet processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional finishing techniques (water washing, chemical treatment, abrasion) are used to create distressed denim, then the desired worn aesthetic is achieved, but environmental impact and resource consumption increase significantly
Solution Approach 1:
The patent replaces traditional mechanical and chemical finishing systems (water washing, chemical bleaching, pumice abrasion) with a laser-based system. The laser uses focused light energy to selectively remove fabric material and create distressed patterns, eliminating the need for water, chemicals, and physical abrasion media while achieving the same aesthetic effect.
Solution Approach 2:
The patent changes the fundamental parameter of the finishing process from wet/chemical to dry/thermal. By using laser energy (optical parameter) to heat and vaporize fabric material directly, the process eliminates water consumption and chemical usage while maintaining control over the distressed appearance through adjustable laser parameters such as power, speed, and pattern.
2Ease of manufacture
If traditional multi-step finishing processes are used, then distressed patterns are achieved, but processing time and costs increase
Solution Approach 1:
The patent merges multiple traditional finishing steps (washing, bleaching, abrasion) into a single laser treatment step. The laser simultaneously achieves material removal, pattern creation, and surface texturing that previously required separate mechanical and chemical processes, thereby reducing total processing time and operational complexity.
Solution Approach 2:
The patent uses computer software to design and preview the distressed pattern before actual laser application. This preliminary digital planning allows for optimization of the laser parameters and pattern design, ensuring that the actual laser finishing process is efficient and achieves the desired result in a single pass without requiring multiple trial runs or adjustments.
3Ease of manufacture
If traditional finishing methods are used, then wear patterns are created, but water and chemical consumption increase to 20-60 liters per garment
Solution Approach 1:
The patent substitutes water-based and chemical-based finishing mechanisms with a laser-based thermal field. The laser beam directly interacts with the fabric through optical energy, causing localized heating and material removal without requiring water for washing or chemicals for bleaching, thereby reducing substance consumption to near zero.
Solution Approach 2:
The laser process is self-contained and does not require external water or chemical resources to function. The laser energy itself performs all necessary functions of material removal and pattern creation, and the process generates minimal waste that does not require water-intensive treatment or chemical neutralization, making the system inherently resource-efficient.

Function Achieved in This Case
This approach reduces environmental impact, processing time, and costs, while maintaining the desired aesthetic of distressed denim, enabling efficient production of various designs from a single fabric template.
Implementation Method 1
A tool 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. Based on a laser input file with a pattern, a laser will burn the pattern onto apparel.
Data Source
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.
