Adhesive Bra Liner Absorbs Sweat to Prevent Stains
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Active women experience embarrassment and discomfort due to noticeable sweat marks around their breasts during physical activity, leading to irritation and discomfort, necessitating an effective absorbent solution to prevent sweat from seeping through bra cups and causing stains.
Innovation Solution
A U-shaped bra liner with an absorbent layer and a backing layer, secured by adhesive, designed to contour the bra cup and absorb sweat, preventing it from reaching the bra and reducing skin irritation, while maintaining a comfortable fit and discrete protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a bra is worn during physical activity, then breast support and coverage are provided, but sweat marks and stains become noticeable causing embarrassment
Solution Approach 1:
The patent introduces a bra liner as an intermediary component between the breast and the bra cup. This liner specifically targets the sweat mark problem area by providing a dedicated absorbent layer that intercepts sweat before it reaches the bra fabric, thereby resolving the contradiction between wearing a bra for support and avoiding sweat marks.
Solution Approach 2:
The bra liner incorporates an absorbent layer with porous structure designed to absorb sweat. The porous material allows it to effectively capture and retain sweat molecules, preventing them from creating visible marks on the bra or clothing, thus addressing the sweat mark issue while maintaining bra functionality.
2Object-affected harmful factors
If absorbent material is added to prevent sweat marks, then sweat absorption improves, but bra structure complexity increases
Solution Approach 1:
The patent segments the bra system into two independent components: the original bra and the separate removable liner. This segmentation allows the absorbent functionality to be added without permanently complicating the bra structure, as the liner can be independently inserted and removed, thus resolving the contradiction between sweat absorption and structural complexity.
Solution Approach 2:
The bra liner is designed as a disposable or easily replaceable component rather than a permanent modification to the bra. This approach allows effective sweat absorption through dedicated absorbent materials while keeping the overall system simple and manageable, addressing the contradiction between absorption capability and structural complexity.
3Object-affected harmful factors
If a liner is inserted to absorb sweat, then sweat marks are prevented, but ease of operation decreases due to additional steps
Solution Approach 1:
The bra liner is designed to provide sweat mark prevention only in the specific area where it is most needed (the breast area prone to visible marks), rather than attempting to address the entire bra. This partial action approach maintains ease of operation by limiting the liner's size and insertion complexity to just the necessary functional zone.

Function Achieved in This Case
Effectively collects and retains sweat, preventing embarrassing stains, reducing skin irritation, and enhancing user confidence and hygiene by providing a comfortable, absorbent, and fragrant lining for the underside of the breast.
Implementation Method 1
The absorbent layer collects and retains the sweat from the breast
Implementation Method 2
The at least one piece of adhesive secures the desired position of the present invention across the inner surface of a bra cup and along the underside of a breast

AI summary
A bra liner is an apparatus that conforms under a breast and is positioned in between the breast and a bra cup. The apparatus includes a flat liner body and at least one piece of adhesive. The flat liner body presses against the underside of a breast and an inner surface of a bra cup. The flat liner body includes an absorbent layer and a backing layer. The absorbent layer collects and retains sweat from the breast. The absorbent layer is connected across the backing layer. The absorbent layer and the backing layer are coextensive with each other. The at least one piece of adhesive is distributed across the backing layer. The at least one piece of adhesive is fixed onto the backing layer, opposite to the absorbent layer. The apparatus further includes a sealing sheet to prevent the at least one piece of adhesive from sticking to unwanted surfaces.
