Catheter Wrap Device With Absorbent Layer For Leakage Control

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing solutions for controlling leakage from male catheters, such as adult diapers and feminine napkins, are uncomfortable, bulky, and not discreet, failing to effectively manage fluid leakage at the insertion point.

Innovation Solution

A catheter wrap device with a leakproof exterior surface and an absorbent interior surface, secured around the penis and catheter tube using a tab with an adhesive fastener, absorbs and contains any leaking fluids, preventing them from reaching clothing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If adult diapers or feminine napkins are used to control catheter leakage, then fluid leakage is absorbed, but the device becomes bulky and uncomfortable

Engineering Contradiction:

Improveleakage controlVSAvoiddevice bulkiness

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

The wrap device is divided into distinct functional layers: an outer impermeable layer for fluid barrier, an intermediate absorbent layer for fluid absorption, and an inner adhesive layer for secure attachment. This segmentation allows each layer to perform its specific function efficiently while keeping the overall device compact.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The wrap device utilizes thin film structures for both the outer impermeable layer and the inner adhesive layer. These thin films provide effective fluid barrier and attachment functions without adding significant bulk, making the device compact and comfortable for wear around the catheter.

Inventive Principle:

Principle #30Flexible shells and thin films

2Reliability

If adult diapers or feminine napkins are used to control catheter leakage, then fluid leakage is contained, but the device is not discreet and causes self-consciousness

Engineering Contradiction:

Improveleakage containmentVSAvoiddiscretion and comfort

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The use of thin film layers creates a sleek, low-profile device that is discreet under clothing and comfortable against the skin. The thin construction eliminates the bulkiness and self-consciousness associated with traditional diaper-based solutions.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The device merges multiple functions into a single integrated wrap: fluid barrier, fluid absorption, and secure attachment. This consolidation eliminates the need for separate layers or additional products, creating a discreet single-unit solution that is comfortable and confident-wearing.

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If a wrap device with absorbent layer is used, then leakage is absorbed, but the device requires additional components increasing complexity

Engineering Contradiction:

Improvefluid absorptionVSAvoidnumber of components

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The device combines the absorbent layer, impermeable layer, and adhesive layer into a single integrated wrap structure. This merging of components simplifies the overall device architecture while maintaining all necessary functions for effective leakage control.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The wrap device employs composite material construction where multiple functional layers are bonded together to form a unified structure. This composite approach provides effective fluid absorption and barrier properties while maintaining device simplicity and ease of application.

Inventive Principle:

Principle #40Composite materials
