Self-Adjusting Undergarment Pouch with Elastic Band
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing male undergarments fail to address discomfort caused by friction and perspiration due to their inflexible design, which does not accommodate varying genitalia sizes and does not adapt to the wearer's genitalia during erections, leading to inadequate support and increased irritation.
Innovation Solution
A self-adjusting pouch design with a horizontal elastic band and four-fold construction in the pouch material, allowing the pouch to expand and retract based on the wearer's genitalia size, providing improved comfort and support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If snug fitting undergarments are used to secure male genitalia tightly against the body, then support is improved, but friction and chafing increase causing discomfort
Solution Approach 1:
The pouch is segmented into multiple layers including an inner pouch and an outer pouch, with the inner pouch providing close contact support and the outer pouch reducing friction against the thighs. This segmentation allows different zones to serve different functions - support near the body and friction reduction away from the body.
Solution Approach 2:
The undergarment features local quality variations through the multi-layer pouch construction where the inner pouch has smooth material for support while the outer pouch has friction-reducing properties. The longitudinal seam and elastic band placement also create localized functional zones for optimal comfort and support.
2Adaptability or versatility
If form fitting design is used to accommodate varying genitalia sizes, then comfort is improved, but the design complexity increases
Solution Approach 1:
The pouch incorporates dynamic elements including an elastic band that stretches and contracts, and a longitudinal seam that allows the pouch to expand and contract. This dynamic construction enables the pouch to adapt to different genitalia sizes and erection states without requiring multiple size variants or complex adjustable mechanisms.
Solution Approach 2:
The pouch design utilizes parameter changes through the elastic band and seam construction that allow the pouch volume and shape to change dynamically. The elastic band provides variable tension that adjusts to different sizes, and the longitudinal seam allows the pouch to expand in multiple directions to accommodate varying genitalia dimensions.
3Strength
If the pouch material is made stretchable to accommodate erections, then support during erections is improved, but the pouch may become too loose during flaccid state
Solution Approach 1:
The elastic band and longitudinal seam create a dynamic pouch that automatically adjusts its tension and volume based on the genitalia state. During erection, the elastic band stretches to provide support; during flaccid state, it contracts to maintain proper fit, eliminating the need to choose between support and fit.
4Strength
If snug fitting material extends down the leg to cover genitals, then support is improved, but moisture accumulation and irritation increase
Solution Approach 1:
The pouch is segmented into multiple layers with different material properties. The inner pouch provides support while the outer pouch is designed with moisture-wicking and breathability properties to reduce moisture accumulation and irritation, allowing each layer to address specific concerns.
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 self-adjusting pouch design significantly reduces friction and irritation, enhancing comfort by accommodating varying genitalia sizes and providing better support during erections, thereby improving overall wearability.

AI summary
Disclosed is a male undergarment that has an expandable pouch. The pouch expands as needed depending on the male's genitalia. The pouch has a horizontal elastic band one and two-third inches below the garment's waistband which enables the pouch to adjust as needed. This horizontal elastic band is to be a half an inch long and one cm width depending on the size of the pouch. This pouch also has a four technique fold of material to increase comfort in the pouch. The two components combined creates a pouch that expands to the male's need.
