Men's Briefs with Segmented Crotch for Ventilation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional men's briefs fail to comfortably separate and contain the penis and scrotum, leading to discomfort and increased temperature, which can affect male sexual function, especially in warm weather, due to their tight design that allows sweat to accumulate and hinder ventilation.
Innovation Solution
The design features a round triangle-shaped opening for the penis and a crescent moon-shaped opening for the scrotum, with a separating cloth and lining that allows for automatic separation and ventilation, preventing sweat buildup and maintaining optimal temperature, using conventional fabrics for cost-effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional briefs are designed to be tight between thighs, then support and containment is improved, but ventilation is reduced and sweat accumulates causing increased temperature
Solution Approach 1:
The brief is divided into distinct functional zones: a first crotch region with tight stitching for support, and a second crotch region with loose stitching for ventilation. This segmentation allows different parts of the same garment to serve contradictory functions - the tight first crotch provides containment while the loose second crotch enables heat dissipation and sweat evaporation.
Solution Approach 2:
Different stitching densities are applied to different locations of the crotch region. The first crotch has dense, tight stitching for support, while the second crotch has sparse, loose stitching for ventilation. This local variation in quality allows the garment to simultaneously provide both containment and thermal regulation.
2Temperature
If the scrotum is allowed to expand to cool down, then temperature regulation is improved, but space requirements increase causing the penis to be pressured downwards
Solution Approach 1:
The crotch region is segmented into two functional zones: the first crotch region provides support and containment for the penis, while the second crotch region provides expanded space for scrotal ventilation and temperature regulation. This spatial segmentation resolves the conflict between needing space for cooling and needing support for the penis.
Solution Approach 2:
The solution moves the ventilation function to a different spatial dimension by creating a separate second crotch region adjacent to the first crotch. Instead of expanding the entire brief, the loose stitching creates a localized volumetric space specifically for scrotal cooling, while the first crotch maintains its supportive structure.
3Stability of the object's composition
If sweat is allowed to accumulate in conventional briefs, then fabric contact is maintained, but evaporation is hindered causing uncomfortable feeling and increased temperature
Solution Approach 1:
The stitching density varies locally across the crotch region, creating areas of different breathability. The loose second crotch allows sweat to evaporate more readily, providing cooling relief, while the tight first crotch maintains fabric contact for support. This local variation in permeability enables both comfort and stability.
4Temperature
If the penis and scrotum are separated by physical means, then temperature control is improved, but complexity of the garment increases
Solution Approach 1:
The crotch region is segmented into two functional zones with different stitching characteristics. The first crotch region with tight stitching provides support, while the second crotch region with loose stitching provides ventilation space. This segmentation achieves temperature control through structural design rather than adding separate mechanical separation devices.
Solution Approach 2:
The loose stitching in the second crotch region automatically creates ventilation space that adapts to the wearer's anatomy and activity level. As the scrotum expands or contracts, the loose stitching allows natural movement and air flow without requiring mechanical adjustment mechanisms. The garment self-regulates temperature through its inherent structural properties.
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 comfortable and refreshing wear by maintaining optimal scrotum temperature, preventing sweat accumulation, reducing the risk of male infertility, and enhancing hygiene through effective ventilation and separation of the penis and scrotum, while being cost-effective and industrially productive.
Implementation Method 1
thanks to the cloth for lining (140) which is capable of absorbing and discharging sweat caused by increasing body temperature from intensive exercise, the temperature of the scrotum is optimized
Implementation Method 2
the sweat that covers the scrotum and the vicinity of men's genital organs is usually difficult to evaporate, which in turn increases the temperature of the testicles
