Moisture Trapping Bra Multi-Layer Sling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional bras fail to effectively manage perspiration, leading to discomfort and unsightly stains, as they lack sufficient moisture absorption and retention capabilities, with existing moisture-wicking materials not adequately addressing the issue of continuous moisture capture and prevention from transferring to clothing.
Innovation Solution
A multi-layered sling construction in the bra, comprising a first wicking layer in contact with the skin, a second trapping layer, and a third moisture barrier layer, which work together to capture and retain moisture, preventing it from reaching the wearer's skin or clothing, using materials like Jacquard, terry cloth, and plastic-based laminates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional fabric bra construction is used to support and position breasts, then basic support and aesthetic presentation are achieved, but perspiration is trapped against the skin causing discomfort and staining
Solution Approach 1:
The bra cup is segmented into multiple functional layers: a moisture-wicking inner layer adjacent to the skin, a moisture-trapping middle layer, and a moisture-barrier outer layer. This segmentation allows each layer to perform a specific function in managing perspiration, moving moisture away from the skin through capillary action while preventing it from reaching the outer garment.
Solution Approach 2:
The bra incorporates composite material construction with at least three different fabric layers having distinct properties. The inner layer uses hydrophilic moisture-wicking material, the middle layer uses absorbent material, and the outer layer uses moisture-barrier material. This composite structure enables the bra to simultaneously provide support, wick moisture, trap perspiration, and prevent staining.
2Object-affected harmful factors
If moisture wicking materials are incorporated into the bra to capture perspiration, then some moisture management is achieved, but the materials lack sufficient absorption capacity to continuously capture and retain moisture
Solution Approach 1:
The moisture management function is segmented across three layers: the inner layer wicks moisture away from skin via capillary action, the middle layer absorbs and traps the wicked moisture, and the outer layer prevents moisture transmission. This segmentation allows continuous perspiration management as each layer handles a specific stage of moisture control.
Solution Approach 2:
The middle moisture-trapping layer acts as an intermediary between the inner wicking layer and the outer barrier layer. It receives moisture from the inner layer through absorption and holds it there, preventing direct transmission to the outer layer while allowing the inner layer to continue wicking moisture from the skin.
3Strength
If constriction structures are used to keep breasts in place, then support and positioning are improved, but skin friction and heat generation increase leading to excessive perspiration
Solution Approach 1:
The invention converts the harmful effect of perspiration generated by constriction into a beneficial outcome by implementing a multi-layer moisture management system. The inner wicking layer captures the perspiration at its source, the middle layer traps it, and the outer layer prevents it from staining clothing. Thus, the constriction-induced perspiration is transformed from a harmful staining issue into a managed physiological function.
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 bra effectively keeps the wearer dry by wicking moisture away from the skin, trapping it with a waterproof membrane, preventing leakage and transfer to outer garments, thus enhancing comfort and hygiene.
Implementation Method 1
The first layer wicking moisture away from the skin of the user
Implementation Method 2
The second layer trapping moisture received from the first layer
Implementation Method 3
The third layer is disposed on a surface of the second a layer which is away from the first layer and is a moisture barrier, preventing moisture from travelling therethrough

AI summary
A bra includes at least one cup. A sling is disposed adjacent the cup. The sling is disposed adjacent the cup in facing relation with a user of the bra. The sling includes a first layer deposed to be in contact with the skin of the user when the bra is worn; the first layer wicking moisture away from the skin of the user. A second layer of the wicking member is disposed on a surface of the first layer away from the skin contacting surface of the first layer. The second layer trapping moisture received from the first layer. A third layer is disposed on a surface of the second a layer which is away from the first layer and is a moisture barrier, preventing moisture from travelling therethrough.
