Four-Way Stretch Coating for Body Shaping Jeans
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing jeans sizing systems fail to adequately address the diverse range of modern consumers' body shapes, resulting in form-fitting jeans that either appear too tight in some areas and too loose in others, lacking support for areas like the stomach, hips, and thighs, which can lead to emphasizing flaws rather than flattering natural curves.
Innovation Solution
A body shaping fit system incorporating a combination of four-way stretch coating formulations, shape contouring panels, and cosmetic finishing techniques to create a form-fitting pair of jeans that enhances natural curves and de-emphasizes flaws, applicable to pants, shorts, and other garments, using the Levi's Curve ID system to determine specific body shapes and sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing jeans sizing systems are used, then mass production and accessibility are achieved, but the jeans fail to accommodate diverse body shapes resulting in poor fit
Solution Approach 1:
The patent applies local quality by dividing the jeans into multiple panels with different fabric compositions and stretch characteristics tailored to specific body regions. Each panel is designed with unique properties to address the specific shaping needs of that area, allowing the garment to adapt to diverse body shapes while maintaining manufacturing feasibility through standardized panel construction methods.
2Shape
If form-fitting jeans are designed, then a tight look is achieved, but the jeans emphasize body flaws rather than flattering natural curves
Solution Approach 1:
The patent implements local quality by assigning different fabric properties to specific panels based on their location on the body. Panels in areas requiring smoothing or support have different stretch and recovery characteristics compared to other areas, allowing the jeans to contour to natural curves while providing strategic support to minimize the appearance of flaws.
Solution Approach 2:
The patent uses composite materials by combining fabrics with different elastic properties, stretch directions, and compressive characteristics in various panels. This multi-material approach enables the jeans to simultaneously achieve form-fitting appearance and flattering silhouette by leveraging the complementary properties of different fabric compositions in strategically placed panels.
3Ease of manufacture
If uniform fabric stretch is used throughout the jeans, then manufacturing simplicity is maintained, but specific body areas lack targeted support
Solution Approach 1:
The patent applies segmentation by dividing the jeans into multiple functional panels, each with customized fabric properties tailored to the specific support needs of that body region. This segmentation allows targeted support for different areas while maintaining ease of manufacture through standardized panel construction and assembly processes.
Solution Approach 2:
The patent implements local quality by varying fabric composition and stretch characteristics in different panels based on the specific anatomical requirements of each body area. This localized customization provides targeted support where needed while maintaining overall manufacturing efficiency through consistent panel fabrication methods.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides a form-fitting, supportive garment that actively shapes the body, smoothing and holding areas like the stomach, seat, and thighs, creating a flattering silhouette while providing lasting comfort and a natural feel.
Implementation Method 1
printing the pattern onto fabric
Implementation Method 2
curing the fabric with the printed pattern
Implementation Method 3
a stretch coating formulation for fabric that provides stretch in all directions (e.g., four way stretch)

AI summary
A body shaping fit system for pants is based on the concept of actively shaping the body's silhouette. This fit system includes: a stretch coating formulation for fabric that provides stretch in all directions (e.g., four way stretch) in an engineered way to target specific parts of the body, shape contouring panels, cosmetic finishing techniques, and seaming and construction techniques for pants. In a specific implementation, a pair of jeans includes a shape contouring panel incorporated onto an inside of the jeans, the panel including a polyurethane based coating with holding power to enhance the body's natural curves while de-emphasizing the body's flaws. The fit system is also applicable to pants, shorts, capris, and other clothing where shaping and support is desirable in the waist, seat, hip, and thigh areas.
