Removable Bra Insert with Adhesive and Snap Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Backless, strapless bras secured with adhesive substances face reduced effectiveness due to moisture and humidity, leading to a shorter lifespan and limited usability.
Innovation Solution
A removable insert with a pressure-sensitive adhesive layer and mechanical connections, such as snap fits or adhesive layers, is designed to attach to the bra cups, allowing for secure attachment to the skin and extending the bra's lifespan by replacing the adhesive layer when it loses effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If adhesive substances are used to secure the brassiere to the breast area, then the brassiere can be worn as a backless strapless design, but the adhesive effectiveness is reduced upon exposure to moisture and humidity
Solution Approach 1:
The brassiere is divided into separate components: a reusable brassiere body and removable inserts. The adhesive layer is segmented and placed only on the inserts rather than the entire brassiere, allowing the adhesive to be replaced independently when it degrades, while the brassiere structure remains intact and reusable.
Solution Approach 2:
The adhesive layer is extracted from the main brassiere structure and placed on separate removable inserts. This allows the adhesive to be taken out and replaced independently when it loses effectiveness, separating the adhesive lifecycle from the brassiere lifecycle.
2Strength
If adhesive substances are used to secure the brassiere, then the brassiere can provide support and coverage, but the adhesive strength is substantially reduced with each wearing, limiting lifespan
Solution Approach 1:
The brassiere system is segmented into permanent structural components and consumable adhesive inserts. This allows the strong adhesive function to be concentrated in replaceable inserts that can be discarded after limited use, while the brassiere body maintains its structural integrity for long-term use.
Solution Approach 2:
The adhesive inserts are designed as disposable, short-living components that are replaced after a few uses when the adhesive degrades. This is more economical than replacing the entire brassiere, allowing users to maintain adhesive strength by periodically replacing only the inexpensive inserts.
3Duration of action of stationary object
If a removable insert with adhesive layer is used, then the adhesive can be replaced when it loses effectiveness, but the device complexity increases with additional components
Solution Approach 1:
The adhesive layer is merged with a supporting insert structure to create a single integrated component. This combining of adhesive and structural support functions into one replaceable unit simplifies the overall system compared to having separate adhesive applications and structural elements.
Solution Approach 2:
The removable inserts serve multiple functions: they provide the adhesive bonding surface, structural support for the breast area, and a mechanism for replacement. This multi-functionality reduces the need for additional separate components to achieve these functions.
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 solution provides a longer-lasting and more reliable attachment system, allowing the bra to maintain its shape and support without the limitations of adhesive degradation, thus extending the bra's usable life and usability.
Implementation Method 1
at least a portion of the second surface configured to provide removable attachment to a user's skin comprises a pressure sensitive adhesive layer disposed at the second surface

AI summary
A removable insert for use with a brassiere includes a body having a first surface and a second surface opposite the first surface. At least a portion of the second surface is configured to provide removable attachment to a user's skin. A mechanical connection associated with the body is configured to provide removable attachment of the body to the brassiere. The first surface is disposed adjacent the brassiere when the body is attached to the brassiere.
