Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current ostomy management technologies face challenges such as skin irritation, stoma leaks, bleeding, and the need for frequent resizing of ostomy bags due to varying stoma sizes over time.

Innovation Solution

An ostomy device comprising an implant shaped in a ring, designed for placement in or adjacent to a hole in the abdominal wall, which includes a surface for contacting a lumen and a region for attaching an ostomy bag. The implant is configured to support the lumen and maintain a consistent stoma size, reducing the need for frequent bag resizing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional ostomy bags are used, then the patient can manage waste removal, but the stoma size may vary over time requiring frequent bag resizing and replacement

Engineering Contradiction:

Improveadaptability to stoma size changesVSAvoidtime spent on frequent bag resizing and replacement

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The implant is placed in advance to establish and maintain a consistent stoma size before the patient begins using the ostomy bag. The implant's structural design ensures the stoma remains a stable, fixed size, eliminating the need for frequent adjustments during bag changes.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The implant acts as an intermediary device between the varying internal stoma conditions and the external ostomy bag. It provides a stable, fixed interface that translates variable physiological conditions into a consistent external opening size, allowing the bag to remain unchanged.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If traditional ostomy bags are used, then waste collection is achieved, but skin irritation and leaks occur due to inconsistent stoma sealing

Engineering Contradiction:

Improvereliability of stoma sealVSAvoidskin irritation and leaks

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The implant is positioned and secured in advance to create a reliable, consistent sealing surface before the ostomy bag is attached. This preliminary establishment of a stable stoma structure ensures consistent sealing and prevents leaks and skin irritation that would otherwise occur with variable stoma sizes.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If the stoma bypass is created, then waste removal path is established, but the stoma size may alter from patient to patient and vary over time

Engineering Contradiction:

Improveaccommodation of varying stoma sizesVSAvoidstoma size consistency

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The implant serves as a mediating structure that receives the variable stoma tissue and transforms it into a consistent, fixed-size opening. It accommodates different initial stoma sizes while maintaining a stable external dimension, providing both adaptability to patient variations and long-term size consistency.

Inventive Principle:

Principle #24Intermediary (Mediator)
