Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing ostomy devices, particularly for ileostomies, suffer from issues such as psychological strain due to visible bags, leakage, skin complications, and discomfort during physical activity, with existing solutions failing to manage large volumes of liquid content effectively.

Innovation Solution

An integrated shield and sleeve system comprising an expandable elongated body with absorbent materials, a protection shield, and withdrawal means, allowing for internal absorption of intestinal fluid and waste, easy handling, and hygienic removal of the ostomy device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a stoma bag is used to collect intestinal content, then the intestinal content can be collected, but the body image is negatively affected and psychological strain increases

Engineering Contradiction:

Improveintestinal content collectionVSAvoidpsychological strain and body image

Core Design Contradiction:

Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The invention extracts the visible bag component from the ostomy system and replaces it with an internal absorbent device that processes intestinal content within the body, eliminating the external collection bag that causes psychological strain and body image issues

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The invention uses a disposable absorbent device that is inserted, performs its function internally, and is then removed and disposed of, replacing the reusable but visually prominent external bag with a temporary internal solution

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Reliability

If an adhesive plate is used to attach the stoma bag, then the bag can be secured to the skin, but skin complications occur due to contact with intestinal content and aggressive adhesive

Engineering Contradiction:

Improvebag attachment securityVSAvoidskin complications

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The invention removes the adhesive plate and external bag assembly entirely, replacing it with an internal absorbent device that eliminates skin contact with intestinal content and the need for aggressive adhesives

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The internal absorbent device acts as an intermediary between the intestinal content and the skin, preventing direct contact and eliminating the need for skin-adhering components

Inventive Principle:

Principle #24Intermediary (Mediator)

3Quantity of substance

If the stoma bag is made larger to accommodate more intestinal content, then the capacity increases, but the weight increases causing discomfort and potential detachment

Engineering Contradiction:

Improveintestinal content capacityVSAvoidbag weight

Core Design Contradiction:

Quantity of substanceVSWeight of moving object

Solution Approach 1:

The invention replaces the mechanical external bag system with a biological/chemical absorption system that utilizes absorbent materials to contain intestinal content without relying on gravity-dependent external containment

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The invention changes the fundamental parameter of content containment from external physical containment (bag volume) to internal absorption (absorbent material capacity), allowing for high capacity without proportional weight increase

Inventive Principle:

Principle #35Parameter changes

4Ease of operation

If physical exercise is performed with an external stoma bag, then mobility is maintained, but leakage risk increases due to pushing, squeezing or clamping the bag

Engineering Contradiction:

Improvephysical activity capabilityVSAvoidleakage prevention

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The invention extracts the external bag that requires manual manipulation and replaces it with an internal device that eliminates the need for pushing, squeezing, or clamping operations during physical activity

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The internal absorbent device performs its containment function automatically without requiring user intervention or manipulation, allowing free movement without leakage risk

Inventive Principle:

Principle #25Self-service

5Ease of operation

If existing stoma bag solutions are used for ileostomies, then the system is simple and easy to handle, but it fails to manage large volumes of liquid content effectively

Engineering Contradiction:

Improvesystem simplicityVSAvoidliquid content management capacity

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

The invention changes the fundamental mechanism from external collection to internal absorption, enabling effective management of large volumes of liquid content through absorbent materials while maintaining operational simplicity

Inventive Principle:

Principle #35Parameter changes
