Solution Overview

Problem

Existing female urination devices (FUDs) are bulky, heavy, and lack collapsibility, making them difficult to carry. Additionally, they often suffer from leakage due to inadequate sealing and lack sufficient structural integrity to keep clothing down during use.

Innovation Solution

A portable urination device with a triangular-shaped fluid collecting body and a spout, designed to be used in a standing position. The device features a pliable material for secure attachment to the body, preventing leakage, and is collapsible for easy storage and transport.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If rigid or semi-rigid plastics and elastomers are used for STP devices, then structural integrity is improved, but device size and weight increase, reducing portability

Engineering Contradiction:

Improvestructural integrityVSAvoiddevice weight

Core Design Contradiction:

StrengthVSWeight of moving object

Solution Approach 1:

The device uses a flexible membrane made of thin plastic material that can be rolled or folded into a compact form for portability, while maintaining sufficient structural integrity when deployed for use

Inventive Principle:

Principle #30Flexible shells and thin films

2Strength

If rigid or semi-rigid plastics and elastomers are used for STP devices, then structural integrity is improved, but device collapsibility is hindered

Engineering Contradiction:

Improvestructural integrityVSAvoidcollapsibility

Core Design Contradiction:

StrengthVSAdaptability or versatility

Solution Approach 1:

The flexible membrane design allows the device to be collapsed or rolled into a compact form for storage and transport, while maintaining the necessary structural integrity during actual use

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The device transitions from a flexible, collapsible state for portability to a rigid, structurally-intact state during use, achieving adaptability between different functional requirements

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If softer elastomeric materials are used for STP devices, then portability is improved, but structural integrity decreases, making them unable to hold clothing down

Engineering Contradiction:

ImproveportabilityVSAvoidstructural integrity

Core Design Contradiction:

Adaptability or versatilityVSStrength

Solution Approach 1:

The flexible membrane provides sufficient structural integrity to hold clothing down during use while maintaining portability through its collapsible nature

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The device combines flexible membrane material with sufficient stiffness characteristics to simultaneously achieve portability and the structural integrity needed to hold clothing in place

Inventive Principle:

Principle #40Composite materials

4Adaptability or versatility

If the device is made to be compact and collapsible, then portability is improved, but structural integrity may be compromised

Engineering Contradiction:

ImproveportabilityVSAvoidstructural integrity

Core Design Contradiction:

Adaptability or versatilityVSStrength

Solution Approach 1:

The flexible membrane is designed to be compact and collapsible for portability while maintaining sufficient structural integrity when deployed for its intended function

Inventive Principle:

Principle #30Flexible shells and thin films

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 device allows women to urinate in a standing position while directing urine away from the body, preventing leakage and maintaining clothing in place. Its collapsible design enhances portability, making it suitable for various environments.

Implementation Method 1

The material of the present invention is somewhat pliable in order to allow the user to firmly press the device against their body to prevent leakage

Methodology Applied

Scientific EffectElasticity: Elasticity

Implementation Method 2

urine is able to enter the fluid collecting portion of the fluid collecting body through the vulval opening before traveling downward both by the force of gravity and by the force of the urine itself being expelled from the body and exiting through the spout

Methodology Applied

Scientific EffectGravity: Gravitation

AI summary

A standing urination device that permits a human with a female urethra to direct their urine into a toilet or onto a surface such as the ground while in a standing position is disclosed. The device is formed of a sheet material and can be folded into an appreciably compact, flat form for transport and storage. The device may be reconfigured into a generally elongated lateral and downwards funnel-shaped configuration with a wide, generally vulval and curving rim opening and an exit spout some distance forwards of the user. Tabs and releasable fasteners are used to hold the device in position.
