FlyFree Briefs With Segmented Crotch and Protective Front Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional male undergarments cause discomfort and pinching of the testicles due to the confinement of the scrotum and penis in the same space, leading to perspiration, chafing, and reduced mobility, while also allowing fabric gathering in the posterior cleft, which increases heat and friction.
Innovation Solution
A single-body construction with elasticized leg openings and a forward-drawing stitching design, combined with a protective panel, separates the scrotum and penis, preventing pinching and fabric gathering, and enhances ventilation and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a separate crotch panel is used to cradle the scrotum, then additional room is provided, but painful pinching of the testicles occurs when sitting
Solution Approach 1:
The undergarment divides the crotch area into two separate compartments: one for the scrotum and another for the penis. This segmentation prevents the scrotum from being pinched by providing dedicated space, while the penis can be extended through an opening to avoid compression. The stitching line creates a clear division that maintains proper anatomical positioning without harmful contact.
Solution Approach 2:
The penis is extracted from the confined crotch space by providing an opening that allows it to extend forward. This removes the penis from the potential pinching zone where the scrotum is cradled, eliminating the harmful interaction between these two anatomical structures while maintaining support for both.
2Device complexity
If the penis and scrotum are confined within the same space, then brief structure is maintained, but perspiration, chaffing and raised testicular temperatures occur
Solution Approach 1:
The single-body construction is segmented into distinct functional zones with a stitching line that separates the scrotum area from the penis area. This segmentation allows each anatomical structure to occupy its own space with appropriate ventilation, preventing the moisture accumulation and friction that cause perspiration and chaffing while maintaining the overall brief structure.
Solution Approach 2:
The design adds a dimensional element by creating a forward extension for the penis through an opening, moving it out of the horizontal plane of the crotch panel. This dimensional change creates vertical and forward space that improves air circulation and reduces contact between the penis and scrotum, thereby reducing perspiration and chaffing.
3Object-affected harmful factors
If elastic is placed at leg openings, then fabric gathering in posterior cleft is prevented, but tension on the fabric increases
Solution Approach 1:
The elastic at the leg openings provides dynamic tension that adapts to movement. This elastic tension actively prevents fabric from gathering in the posterior cleft by maintaining constant outward pressure on the fabric edges, counteracting the natural tendency of fabric to bunch up during movement while distributing the stress evenly across the elastic material.

AI summary
A men's undergarment consisting of a torso-encircling waistband attached to a single panel of fabric with the wider portion affixed at the back of the waistband, then narrowing between the legs before re-attaching at the front of the waistband to form the brief. A line of stitching spans the narrow panel from thigh to thigh. The front portion of the garment includes a sleeve formation with a soft, piped opening through which the penis extends. A wide, exterior panel drapes loosely from the waistband covering the front opening and shielding the penis.
