Garment Liner Couplers for Underwear Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional underwear often causes discomfort due to elastic bands, friction, and tight-fitting portions that lead to pressure and movement issues, necessitating frequent adjustments.
Innovation Solution
A hygienic garment liner that attaches outwardly to the interior surface of clothing instead of directly to the body, using couplers such as magnets, Velcro, or adhesive materials to secure it in place, eliminating the need for elastic bands and reducing friction and pressure points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If elastic bands are used to tighten around the waist to keep underwear in place, then the underwear remains securely positioned, but pressure and discomfort are caused to the wearer
Solution Approach 1:
The patent introduces an intermediary attachment mechanism (couplers with fastening elements) between the underwear and the wearer's body, replacing direct elastic band contact. This mediator allows secure positioning through mechanical coupling at specific points rather than continuous pressure, thereby maintaining reliability while reducing harmful pressure effects on the body.
Solution Approach 2:
The continuous elastic band is segmented into discrete coupling points distributed around the waist and leg areas. Instead of one continuous tightening element, multiple separate couplers are positioned at intervals, providing stabilization through distributed anchoring points rather than uniform pressure, thus reducing discomfort while maintaining positioning stability.
2Reliability
If tight-fitting portions are used to prevent movement, then underwear stays in place, but friction and bunching occur causing discomfort
Solution Approach 1:
Couplers serve as intermediary anchoring points that provide stabilization without requiring continuous tight contact between fabric and body. The fastening elements create discrete attachment zones that prevent movement while allowing fabric to move freely in non-coupled areas, reducing friction and bunching effects.
Solution Approach 2:
The underwear design allows dynamic movement of fabric between fixed coupling points. The portions between couplers are permitted to move and adapt to body motion naturally, while the couplers themselves remain relatively fixed, providing stability without constraining the entire garment, thus reducing friction and bunching.
3Reliability
If conventional underwear is designed to fit closely to the body, then it provides coverage and stays in place, but it causes pressure and requires frequent adjustments
Solution Approach 1:
The coupler-based attachment system acts as an intermediary mechanism that provides secure positioning without requiring continuous adjustment. The mechanical fastening elements maintain stable attachment over time, reducing the need for frequent repositioning compared to conventional elastic band designs that may shift or loosen.
Solution Approach 2:
The underwear with coupler attachment systems provides self-adjusting capabilities through the mechanical properties of the fastening elements. The couplers can accommodate natural body movements and shape changes automatically, maintaining stable attachment without requiring manual intervention or frequent adjustments by the wearer.
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 liner provides comfort by minimizing friction and pressure, preventing bunching and movement, while maintaining hygiene by acting as a changeable barrier between the body and clothing, and can be easily removed and washed.
Implementation Method 1
a first set of one or more magnetic couplers attached to an exterior surface of the garment liner

AI summary
Embodiments of the invention provide a garment liner that couples to the interior of a clothing article. The garment liner can replace typical underwear. The garment liner can shield clothing from a person's body, and can improve comfort by conforming to the shape of the clothing instead of to the body. Various mechanisms are provided for coupling the garment liner to the clothing article.
