Solution Overview

Problem

Existing urinary devices for incontinent males are cumbersome, difficult to fasten and re-fasten, often require two hands, and can be uncomfortable due to inconsistent pressure, lacking easy adjustment and one-handed application.

Innovation Solution

A urinary device with a malleable band at the proximal end that can be easily opened and closed with one hand, allowing for adjustable pressure and no direct contact with the penis, featuring a moisture-absorbent inner layer and moisture-resistant outer layer, enabling quick and comfortable use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If adhesive or Velcro fasteners are used to secure the device to the penis, then the device can be fastened, but it requires two hands to operate and is difficult to fasten and re-fasten

Engineering Contradiction:

Improveease of fasteningVSAvoidfastening mechanism complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical fastening systems (adhesive, Velcro) with a simple elastic band mechanism that uses elastic tension to secure the device. This substitution enables one-handed operation while eliminating the complexity of multiple fastening components.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent extracts and removes the complex fastening mechanisms (adhesive, Velcro) from the device, retaining only the essential elastic band component. This simplification maintains fastening functionality while enabling easier one-handed operation.

Inventive Principle:

Principle #2Taking out (Extraction)

2Adaptability or versatility

If elastic band is used to fasten the device, then the device can be secured, but the pressure on the penis cannot be easily adjusted and may cause circulation problems or be too loose

Engineering Contradiction:

Improvepressure adjustment capabilityVSAvoidease of pressure adjustment

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent incorporates a dynamic adjustment mechanism that allows the elastic band tension to be modified after application. This enables users to adjust the pressure on the penis to achieve optimal fit without circulation problems or excessive looseness.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent allows changes in the elastic band's physical parameters (tension, positioning) after the device is applied. This enables pressure adjustment to accommodate different penis sizes and user comfort requirements while maintaining secure fastening.

Inventive Principle:

Principle #35Parameter changes

3Ease of operation

If the device is designed to cover the penis, then urinary incontinence can be managed, but the user must directly touch or contact the penis during application and re-application

Engineering Contradiction:

Improvehygiene during applicationVSAvoidapplication mechanism complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary mechanism (such as a retrieval string or extended handle) that allows users to apply and remove the device without direct hand contact with the penis. This intermediary tool maintains hygiene while enabling simple one-handed operation.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Ease of operation

If the open end is designed to be easily opened for insertion, then one-handed application is possible, but the open end may not remain opened without hand assistance

Engineering Contradiction:

Improveease of insertionVSAvoidopen end stability

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent incorporates a preliminary action mechanism (such as a retrieval string or positioning aid) that maintains the open end in an opened position during insertion. This preliminary setup eliminates the need for continuous hand assistance while enabling one-handed application.

Inventive Principle:

Principle #10Preliminary action

AI summary

A urinary device for use on a penis of a male suffering from urinary incontinence. The device comprises a body having a closed distal end and an open proximal end and defining a cavity therein. The body has an inner layer made of a moisture absorbent material and an outer layer made of a moisture resistant material. A malleable material encircles a portion of the proximal end of the body wherein the proximal end is adapted to conform to the shape of the malleable material.
