Solution Overview

Problem

The existing methods for applying urinal condoms are difficult for individuals with limited manual dexterity, often resulting in leaks, poor fitting, and are unsuitable for those with a retracted penis or impotence, as they require external assistance and can be challenging to use effectively.

Innovation Solution

A device comprising a receiving bell, vacuum pump, and connection unit that allows for easy application of urinal condoms by creating negative pressure, ensuring a secure fit and simplifying the process, with interchangeable parts for different sizes and configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual application of urinal condom is attempted by individuals with limited dexterity, then the process becomes unnecessarily difficult and time-consuming, but external assistance is required which reduces privacy and independence

Engineering Contradiction:
Improveease of applicationVSAvoidapplication process complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

A receiving bell serves as an intermediary device between the condom and the user's hands. The condom is first placed on the receiving bell, which holds it in position, and then the entire assembly is applied to the penis. This mediator eliminates the need for direct manual manipulation of the condom during application.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The condom is preliminarily positioned on the receiving bell before actual application to the penis. This preliminary arrangement ensures correct orientation and placement, allowing the user to simply transfer the pre-positioned condom from the bell to the penis without complex manual dexterity requirements.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If traditional manual application methods are used, then the process requires high manual dexterity, but this excludes individuals with retracted penis or impotence from using urinal condoms independently

Engineering Contradiction:
Improveuser accessibilityVSAvoidapplication difficulty
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The device enables self-service application for individuals who previously could not independently apply urinal condoms. By combining the receiving bell with a simple holding mechanism, the system allows users with limited dexterity, retracted penis, or impotence to apply the condom themselves without requiring external assistance.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The receiving bell acts as a mediator that adapts to different anatomical conditions. Whether the penis is flaccid, retracted, or has limited mobility, the bell provides a stable intermediate platform that facilitates attachment of the condom, making the system universally accessible.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If the condom is applied without proper support structure, then application may be quick, but leaks and folds occur resulting in poor seating

Engineering Contradiction:
Improvefit qualityVSAvoidapplication speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The receiving bell changes the physical parameters of condom placement by providing a curved surface that matches the anatomy of the penis. This geometric parameter change ensures the condom is pre-formed into the correct shape before application, preventing folds and ensuring proper seating that eliminates leaks.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The condom is preliminarily shaped and positioned on the receiving bell, which pre-forms it into the correct configuration. This preliminary action ensures that when the condom is transferred to the penis, it is already in the proper shape and position, eliminating the need for post-application adjustments and ensuring reliable fit from the start.

Inventive Principle:
Principle #10Preliminary action

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 facilitates easy and secure application of urinal condoms for various users, including those with limited dexterity or specific anatomical conditions, by providing a perfect fit and minimizing leaks, while allowing for easy removal and unrolling.

Implementation Method 1

a device for generating a negative pressure... the penis is sucked into the area of the urinal condom resting on the receiving bell due to the negative pressure generated by the operation of the vacuum pump

Methodology Applied
Scientific EffectNegative pressure: Vacuum
