Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Military uniforms with woven rip stop textures and printed camouflage patterns lack a three-dimensional look and texture, resulting in an insufficient camouflaging effect due to limited color display and clear pattern boundaries, which also increases manufacturing time and cost.

Innovation Solution

The use of dyed warp and weft threads with various colors, arranged in a gradient pattern using a jacquard weaving machine to create a three-dimensional camouflage effect, combining plain weave, twill weave, and rip stop weave techniques to enhance aesthetics and functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If printed camouflage patterns are used on woven fabric, then manufacturing process is simple, but camouflaging effect is insufficient due to limited color display and clear pattern boundaries

Engineering Contradiction:

Improvemanufacturing process simplicityVSAvoidcamouflaging effect

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The invention applies preliminary action by pre-dyeing the threads with multiple colors before weaving. The warp threads are dyed with first and second colors, while weft threads are dyed with third and fourth colors. This preliminary color application eliminates the need for post-weaving printing processes, while simultaneously achieving superior camouflaging effect through multi-color integration in the fabric structure itself.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The invention applies local quality by creating different color zones within the fabric through selective thread arrangement. Different regions of the fabric display different color combinations (first color, second color, third color, fourth color) in a checked pattern, allowing the fabric to exhibit spatially varying optical properties that enhance camouflage effectiveness while maintaining structural integrity.

Inventive Principle:

Principle #3Local quality

2Ease of manufacture

If printed camouflage patterns are used, then manufacturing cost is reduced, but three-dimensional look and texture are insufficient

Engineering Contradiction:

Improvemanufacturing costVSAvoidthree-dimensional look and texture

Core Design Contradiction:

Ease of manufactureVSShape

Solution Approach 1:

The invention applies composite materials by integrating multiple colored threads (warp threads with first and second colors, weft threads with third and fourth colors) into a single fabric structure. This composite approach creates inherent three-dimensional texture through the interlacing of differently colored threads, eliminating the need for surface printing while achieving both cost efficiency and aesthetic quality.

Inventive Principle:

Principle #40Composite materials

3Reliability

If dyeing threads before weaving is used, then camouflaging effect is improved, but manufacturing complexity increases

Engineering Contradiction:

Improvecamouflaging effectVSAvoidmanufacturing complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The invention applies segmentation by dividing the fabric into distinct woven regions with different color combinations. The fabric includes first regions with first color, second regions with second color, third regions with third color, and fourth regions with fourth color, achieved by segmenting the weaving process into distinct zones with different thread arrangements. This segmentation simplifies the overall manufacturing by breaking down the complex camouflaging pattern into manageable colored sections.

Inventive Principle:

Principle #1Segmentation

4Shape

If jacquard weaving machine is used, then three-dimensional pattern is displayed, but manufacturing time increases

Engineering Contradiction:

Improvethree-dimensional patternVSAvoidmanufacturing time

Core Design Contradiction:

ShapeVSProductivity

Solution Approach 1:

The invention applies copying by using the jacquard weaving machine to replicate complex three-dimensional camouflage patterns through programmed thread selection. The machine copies the desired camouflaging effect by automatically selecting and arranging colored threads according to pre-programmed patterns, reducing manual intervention while maintaining high pattern fidelity and three-dimensional quality.

Inventive Principle:

Principle #26Copying

AI summary

A method of manufacturing camouflage clothing worn by soldiers is provided. The optimum camouflage clothing satisfying clothing functionality, aesthetics, and camouflaging effect, which is an important function for military uniforms, is provided while the optimum camouflage clothing is economical. The camouflage clothing is formed by dyeing threads i.e. row material, using the dyed threads as warp threads and weft threads, and weaving the camouflage clothing using a jacquard weaving machine. Herein, the warp threads and the weft threads are gradationally arranged to form a delicate-colored checked pattern while a three-dimensional pattern is displayed by the jacquard weaving machine.
