Garment Liner for Reducing Friction and Maintaining Cleanliness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional underwear often causes discomfort due to elastic bands, friction, and body-hugging features that lead to bunching and movement, necessitating frequent adjustments.
Innovation Solution
A hygienic garment liner that attaches to the inside of clothing instead of directly to the body, using various materials and couplers like buttons, magnets, and adhesives to secure it in place, eliminating the need for elastic bands and body-hugging designs, and allowing for customizable thickness and material distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If elastic bands are used to tighten underwear around the waist, then the underwear stays in place, but pressure and discomfort are caused
Solution Approach 1:
The patent removes the elastic band entirely from the underwear design. Instead of using elastic material to provide tension, the invention uses a linerless in-pants construction where the pants themselves provide the securing function through their fit and design, eliminating the harmful pressure and discomfort associated with elastic bands
Solution Approach 2:
Rather than having the underwear actively cling to the body through elastic tension, the invention inverts the approach by having the pants passively contain the linerless in-pants through their own structural fit, reversing the traditional active-cling mechanism
2Reliability
If underwear is designed to hug the body tightly, then it stays in place, but friction causes bunching and movement requiring frequent adjustments
Solution Approach 1:
The patent eliminates the traditional underwear layer that causes friction and bunching. By removing this intermediate layer and creating a linerless in-pants design, the friction between separate fabric layers is eliminated, reducing bunching and the need for adjustments
Solution Approach 2:
The invention merges the functions of traditional underwear and pants into a single integrated linerless in-pants construction. This consolidation eliminates the friction and movement issues that arise from multiple separate layers rubbing against each other
3Object-affected harmful factors
If traditional underwear is used, then body coverage is provided, but cleanliness of outer clothing is compromised
Solution Approach 1:
The patent removes the traditional underwear layer entirely, replacing it with a linerless in-pants design where the pants themselves provide the protective barrier. This simplification maintains the cleanliness function while reducing garment complexity
Solution Approach 2:
The pants are designed to serve multiple functions simultaneously: they provide the protective barrier for cleanliness, the structural support for fit, and the comfort layer for wearability, eliminating the need for separate underwear

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.
