Bra with Cut-Resistant Pocket for Concealed Self-Defense Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing athletic wear bras lack a safe and easily accessible means to carry self-defense items like knives or pepper spray, making them cumbersome and difficult to use in emergency situations, especially with the trend towards form-fitting designs that inhibit movement and accessibility.
Innovation Solution
A bra with a built-in cut-resistant pocket or sheath made from materials like webbed nylon, designed to securely hold a knife or aerosol canister, providing immediate access while being concealed and comfortable during physical activity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a knife or pepper spray is carried in the hand while jogging or exercising, then it is easily accessible for self-defense, but it is cumbersome and not desirable
Solution Approach 1:
The knife or pepper spray container is nested within a sheath that is integrated into the bra structure. The sheath is positioned within the bra body, allowing the self-defense item to be carried concealed and comfortably without being cumbersome, while still maintaining easy accessibility when needed.
2Object-affected harmful factors
If a clip is used to secure the knife or pepper spray out of the way, then it is concealed, but it may not be immediately accessible in the event of a surprise attack
Solution Approach 1:
The sheath is pre-positioned within the bra structure during manufacturing, with the opening strategically located to allow immediate access. This preliminary positioning ensures that when an attack occurs, the user can immediately retrieve the knife or pepper spray without delay, while the item remains concealed during normal wear.
3Device complexity
If a clip with single attachment point is used, then it is simple, but it permits movement or rotation of the knife or pepper spray during exercise
Solution Approach 1:
The sheath is merged with the bra structure through integration during manufacturing. The sheath becomes a permanent component of the bra, eliminating the need for separate clips or attachment mechanisms. This merging provides stable positioning of the knife or pepper spray during exercise while maintaining simplicity, as the sheath is built into the bra body rather than being a separate attachment device.
4Reliability
If external attachment on waistband is used, then it is secure, but it is bulky and inhibits movement
Solution Approach 1:
Instead of attaching the self-defense item externally on the waistband (horizontal dimension), the sheath is integrated vertically into the bra structure. This dimensional change allows the item to be secured securely within the bra body while minimizing bulk and inhibiting movement, as the sheath conforms to the body's natural contours rather than adding external bulk.

AI summary
An article of clothing providing a pocket for safely and securing concealing a self-defense device in an easily accessible location. The article of clothing may be a bra or tank-top having a pocket or sheath made of a cut-resistant material and configured for removably securing a knife or dagger. The pocket may also be configured to removably secure an aerosol canister containing a chemistry configured to deter an attacker, such as pepper spray. In one embodiment, the article of clothing is a bra with a pocket position between the two cups of the bra. The pocket is configured to removably secure a sheath made of a cut-resistant material, wherein the sheath is configured to removably secure a knife or dagger.
