Underwear With Double-Walled Crotch Pockets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional garment pockets are publicly visible, compromising security and privacy, and existing solutions for underwear pockets either cause unnatural bulges or are inconvenient to access, failing to provide a secure and discreet way to hide items while allowing frontal access.
Innovation Solution
An undergarment design featuring an elastic waistband, leg portions, and a crotch area with an opening for the male organ, incorporating double-walled pockets externally affixed along the crotch area, allowing the male organ to pass through while providing a secure space to store items without visible bulges or inconvenient access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pockets are provided on underwear to store items, then security and privacy are improved, but the pockets become publicly visible and susceptible to pickpocketing or pat-downs
Solution Approach 1:
The patent implements a double-walled pocket structure where an inner pocket is nested within an outer pocket. The inner pocket contains the stored items while the outer pocket provides structural support and conceals the inner pocket's contents. This nested configuration allows items to be hidden discreetly against the body without creating visible external bulges, resolving the contradiction between security through pocket storage and invisibility to prevent pickpocketing.
2Reliability
If a filled pocket is located on a non-crotch area, then items can be stored securely, but it causes an unnatural bulge that reveals hidden items
Solution Approach 1:
The double-walled pocket structure enables the inner pocket to be compressed against the body without creating significant external volume. The outer wall absorbs the bulk of the pocket's volume while the inner wall remains flush against the skin, allowing items to be stored securely without producing unnatural bulges that would reveal the hidden contents.
Solution Approach 2:
The patent applies different functional qualities to different parts of the pocket structure. The outer wall is designed to be structurally supportive and concealing, while the inner wall is designed to be form-fitting and flush against the body. This differentiation of local qualities allows the pocket to maintain a smooth external appearance while providing secure item storage.
3Reliability
If a crotch-blocking pocket is used to hide items, then security is improved, but it blocks frontal access to the male organ requiring inconvenient access methods
Solution Approach 1:
The crotch area is segmented into distinct functional zones: the opening for male organ access remains clear and unobstructed, while the double-walled pockets are positioned laterally on either side of the opening. This segmentation allows the pocket structure to provide security without interfering with the passageway, enabling both secure item storage and convenient frontal access to the male organ.
Solution Approach 2:
The patent applies different functional qualities to different regions of the crotch area. The central opening region maintains high accessibility with no blocking structures, while the lateral regions contain the pocket structures for secure storage. This spatial differentiation of functional qualities resolves the contradiction between security through pocket placement and ease of access to the male organ.
4Difficulty of detecting and measuring
If double-walled pockets are affixed externally at the crotch area, then items can be stored discreetly, but the structure becomes more complex
Solution Approach 1:
The double-walled pocket structure, while adding complexity, achieves discreetness by nesting the inner pocket within the outer pocket. This configuration allows both walls to be affixed externally at the crotch area, providing structural support and concealment while maintaining a relatively compact and integrated design that does not significantly increase overall device complexity.
