Solution Overview

Problem

Existing deodorizing compositions and methods for ostomy pouches are not sufficient to effectively manage odors over an extended period, leading to discomfort and embarrassment for users.

Innovation Solution

A deodorizing composition comprising a combination of citric acid, citric acid salt, cocamidopropyl betaine, zinc ricinoleate, and optionally a preservative or antimicrobial agent, is incorporated into a hydrophilic polyurethane or hydrogel, which is then placed in an ostomy device to enhance odor control and longevity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If conventional deodorizing compositions are used in ostomy pouches, then some odor reduction is achieved, but the deodorizing effect is not sustained over extended periods

Engineering Contradiction:

Improveduration of deodorizing effectVSAvoidconsistency of odor control

Core Design Contradiction:

Duration of action of moving objectVSReliability

Solution Approach 1:

The patent changes the chemical parameters of the deodorizing composition by using a specific combination of citric acid (5-15%), citric acid salt (5-15%), cocamidopropyl betaine (2-10%), and zinc ricinoleate (5-15%). This optimized parameter range provides sustained deodorizing effect while maintaining stability over extended periods in ostomy pouches.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite deodorizing system by combining multiple active ingredients (citric acid, citric acid salt, cocamidopropyl betaine, zinc ricinoleate) with optional preservatives and antimicrobial agents. This composite approach ensures both prolonged duration and reliable consistency of odor control through synergistic interactions among components.

Inventive Principle:

Principle #40Composite materials

2Object-affected harmful factors

If deodorizing compositions are added to ostomy pouches, then odor control is improved, but the complexity of the device increases

Engineering Contradiction:

Improveodor controlVSAvoidcomplexity of ostomy device

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent merges the deodorizing function with the ostomy pouch structure by incorporating the deodorizing composition directly into the pouch or providing it as an integrated sachet that combines multiple functions (deodorizing, preservative, antimicrobial) in a single unit, thereby reducing overall device complexity while maintaining effective odor control.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The deodorizing composition serves multiple functions simultaneously: it neutralizes odors through citric acid and zinc ricinoleate, preserves the pouch contents through paraben, and provides antimicrobial protection. This multi-functionality eliminates the need for separate devices for each function, reducing overall system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Speed

If the deodorizing composition is placed directly in the ostomy pouch, then immediate odor neutralization occurs, but the composition degrades quickly and loses effectiveness

Engineering Contradiction:

Improvespeed of odor neutralizationVSAvoidlongevity of deodorizing composition

Core Design Contradiction:

SpeedVSDuration of action of moving object

Solution Approach 1:

The patent applies preliminary action by pre-mixing the deodorizing ingredients (citric acid, citric acid salt, cocamidopropyl betaine, zinc ricinoleate) with preservatives and antimicrobial agents in stable concentrations before placement in the pouch. This pre-prepared composition maintains stability during storage and immediately upon deployment, providing both rapid initial effect and prolonged duration.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent employs a disposable deodorizing sachet or integrated pouch system that contains the complete deodorizing composition. This single-use design ensures that each pouch receives a fresh, stable composition with immediate effectiveness, while the disposable nature prevents degradation issues associated with reusable systems.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)
