Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The traditional process of producing jeans with finishing patterns is resource-intensive, time-consuming, and costly, requiring significant water and chemical usage, which poses an environmental impact, and lacks an efficient method for creating and previewing patterns before laser finishing.
Innovation Solution
A software and laser-based system that allows users to create, preview, and modify designs in real-time on a computer screen, with the ability to project and refine images onto a three-dimensional mannequin, using a laser to burn patterns onto jeans while controlling parameters like power and frequency to achieve desired shades and patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional water and chemical-based finishing processes are used, then finishing patterns can be achieved, but environmental impact and resource consumption increase significantly
Solution Approach 1:
The patent replaces traditional mechanical and chemical finishing processes (water washing, chemical treatments, pumice stone abrasion) with a laser-based system. The laser beam directly ablates and heats the denim fabric to create finishing patterns, eliminating the need for water, chemicals, and physical abrasives, thereby resolving the contradiction between manufacturability and environmental impact.
Solution Approach 2:
The patent utilizes controlled changes in laser parameters (power, pulse duration, scanning speed, wavelength) to achieve different finishing effects on denim. By adjusting these parameters, the laser can create various patterns, depths, and textures without changing the fundamental laser-based process, allowing versatile finishing while maintaining environmental benefits.
2Manufacturing precision
If traditional multi-step finishing processes are used, then desired fading and distressing effects can be achieved, but processing time increases
Solution Approach 1:
The patent extracts and consolidates multiple traditional finishing steps (water washing, chemical treatment, mechanical abrasion, enzyme treatment) into a single laser processing step. The laser performs ablation, heating, and pattern creation simultaneously in one pass, dramatically reducing processing time while maintaining or improving pattern quality through precise digital control.
Solution Approach 2:
The laser processing system operates continuously with the laser beam scanning across the denim surface without interruption, creating finishing patterns in a single continuous pass. This eliminates the sequential nature of traditional multi-step processes where garments must be transferred between different treatment stations and waiting periods.
3Manufacturing precision
If traditional finishing methods are used, then distressed looks can be achieved, but processing costs and resource usage increase
Solution Approach 1:
The patent replaces resource-intensive mechanical and chemical systems with an optical laser system that requires minimal consumables. The laser beam delivers precise energy to create distressed effects without consuming water, chemicals, or physical abrasives, improving productivity by eliminating resource handling, waste treatment, and process monitoring associated with traditional methods.
Solution Approach 2:
The laser processing system produces minimal waste compared to traditional methods. The primary byproduct is vaporized fabric material that dissipates as smoke, eliminating the need for wastewater treatment, chemical disposal, and abrasive waste management. This recovery approach improves productivity by removing waste handling steps from the production process.
4Adaptability or versatility
If multiple fabric templates are maintained for different designs, then design variety can be achieved, but inventory costs and complexity increase
Solution Approach 1:
The patent uses software-controlled laser parameters (power, speed, pattern geometry, scanning paths) to generate unlimited design variations from a single fabric template. The digital design system allows users to modify parameters and create custom patterns without physical template changes, eliminating inventory complexity while maximizing design versatility through programmable control.
Solution Approach 2:
The system uses digital copies and representations of designs in software rather than physical fabric templates. Design patterns are stored as digital files that can be replicated, modified, and applied to any garment through laser processing, eliminating the need to maintain physical inventories of different fabric templates while providing unlimited design flexibility.
