Solution Overview

Problem

Existing male underwear often causes discomfort due to friction, overheating, sweating, odor, and insufficient support, leading to impaired sperm production and frequent adjustments.

Innovation Solution

A clothing item with a frontal pouch featuring heat conducting elements, such as metallic yarns, that dissipate heat through thermal conductivity, reducing friction and odor while providing support and ventilation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If conventional fabric materials are used in underwear, then the garment is comfortable and flexible, but heat accumulates in the genital area causing overheating and impaired sperm production

Engineering Contradiction:
Improvegenital area temperatureVSAvoidoverheating
Core Design Contradiction:
TemperatureVSObject-affected harmful factors

Solution Approach 1:

The patent changes the thermal conductivity parameter of the fabric by incorporating metallic yarns (silver, copper, or aluminum) with high thermal conductivity values (silver: 430 W/mK, copper: 400 W/mK, aluminum: 240 W/mK) into the textile structure. This transforms the fabric from a thermal insulator to a thermal conductor, enabling efficient heat transfer from the genital area to the outer surface of the underwear where heat can dissipate to the environment.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite textile material by combining conventional textile fibers with metallic yarns having high thermal conductivity. The metallic yarns are integrated into the fabric structure to form a heat-conducting network that maintains the flexibility and comfort of the base fabric while adding thermal management capabilities. This composite structure allows simultaneous achievement of comfort and heat dissipation.

Inventive Principle:
Principle #40Composite materials

2Reliability

If tight-fitting underwear is used to provide support, then support for genitalia is improved, but friction between genitals and legs increases causing discomfort and irritation

Engineering Contradiction:
Improvegenital supportVSAvoidfriction
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent modifies the surface properties of the fabric by incorporating metallic yarns that reduce the coefficient of friction between the underwear and the skin. The metallic components create a smoother surface interface that decreases frictional forces during movement, thereby reducing irritation and discomfort while maintaining the supportive function of the tight-fitting garment.

Inventive Principle:
Principle #35Parameter changes

3Strength

If conventional synthetic fabrics are used, then the garment is durable and easy to manufacture, but sweating and odour problems occur due to poor breathability

Engineering Contradiction:
Improvegarment durabilityVSAvoidodour and sweating
Core Design Contradiction:
StrengthVSObject-generated harmful factors

Solution Approach 1:

The patent combines synthetic fabric base materials (providing durability and ease of manufacture) with metallic yarns (improving breathability and odor resistance). The metallic components have natural antimicrobial properties that inhibit bacterial growth, thereby reducing odor generation. Additionally, the high thermal conductivity of the metallic yarns enhances moisture evaporation, reducing sweating issues while maintaining the durability of the synthetic base fabric.

Inventive Principle:
Principle #40Composite materials

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 heat conducting elements effectively cool the genital area, reduce friction and odor, and enhance support, improving comfort and reducing the need for frequent adjustments.

Implementation Method 1

the rear panel comprises at least one heat conducting element connecting a lower scrotum-underlying portion of the rear panel with the exposed upper portion of the rear panel wherein the heat conducting element comprises a material that has a thermal conductivity of at least 200 watts per metre-kelvin

Methodology Applied
Scientific EffectThermal conduction: Conduction (thermal)

Implementation Method 2

heat may be conducted by the heat conducting elements to the exposed portion of the panel which then effectively acts as a radiator, dissipating heat from the item of clothing and cooling the user's scrotum

Methodology Applied
Scientific EffectThermal radiation: Thermal Radiation
