Garment Liner With Higher Weft Stretch Resolving Seam Friction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bottom garments, such as jeans and yoga pants, often compromise comfort due to mismatched stretch parameters in seams and fabric, leading to discomfort and chafing, especially when worn in smaller sizes or with lower waistlines.
Innovation Solution
A bottom garment featuring front and back panels made of high weft-stretch fabric with an integrated garment lining that has greater weft stretch than the panels, and an elastic support band for improved fit and comfort, along with optional pocket assemblies and fly assemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If jeans are made with elastic fibers to improve comfort and styling, then the fabric becomes more stretchy and comfortable, but the seams do not share the same stretch parameters and create uncomfortable contact points with the wearer's skin
Solution Approach 1:
A seamless liner is introduced as an intermediary layer between the stretch denim garment and the wearer's skin. The liner has higher stretch properties than the outer garment, allowing it to accommodate the garment's movement while maintaining a smooth interface with the skin, thereby eliminating uncomfortable seam contact points.
Solution Approach 2:
The liner is designed with different stretch parameters than the outer garment - specifically higher weft stretch (80-200% vs 25-60%) and lower warp stretch. This parameter mismatch allows the liner to move independently and accommodate the outer garment's movement without creating restrictive or uncomfortable contact points.
2Stability of the object's composition
If jeans are sized smaller to maintain fit while accommodating stretch, then the garment maintains its shape and fit, but the seams create increased abrasion against the skin
Solution Approach 1:
The seamless liner acts as a protective intermediary between the garment seams and the wearer's skin. By providing an additional layer of fabric, the liner reduces direct contact and friction between the seams and skin, thereby minimizing abrasion while allowing the garment to maintain its smaller size for proper fit.
3Shape
If lower waistlines are used in bottom garments, then the styling is updated and consumers can secure the garment with a tighter fit, but different undergarments with less coverage fabric are required which contribute to chafing and decreased comfort
Solution Approach 1:
The liner is integrated directly into the garment construction, merging the functions of the garment and undergarment into a single unified piece. This eliminates the need for separate undergarments and provides continuous coverage that prevents chafing while maintaining the desired lower waistline styling.
Solution Approach 2:
The liner serves as an intermediary layer that provides the coverage and protection normally provided by separate undergarments. It creates a smooth barrier between the outer garment and the wearer's skin, preventing chafing in the waistline and hip areas while allowing the garment to maintain its modern lower waistline design.
4Ease of operation
If yoga clothing is designed with high stretch fabric for comfort, then the garment provides smooth stretchy comfort, but it is considered too informal for situations where jeans or other bottom garments are appropriate
Solution Approach 1:
The invention merges the comfort features of yoga wear (seamless construction, high-stretch liner) with the styling and structure of traditional denim garments. The outer garment maintains the classic jean appearance and structure, while the integrated liner provides the comfort and stretch of yoga wear, creating a hybrid garment that is both comfortable and appropriate for various occasions.
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 garment provides enhanced comfort by allowing greater flexibility and reduced friction, maintaining a secure fit without compromising style, and can be adapted for various styles like jeans, pants, capris, skirts, and shorts.
Implementation Method 1
The bottom garment may further include an elastic support band for maintaining the position of the garment when the garment is worn

AI summary
A bottom garment including a front panel, a back panel, and a garment lining. The front panel formed of a first fabric and the garment lining formed of a second fabric. The garment lining attached to an inside surface of the front panel and an inside surface of the back panel. The garment lining attached above a crotch point of the garment such that the garment lining is less restrictive than the front panel.
