Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing ostomy device pulling tabs are prone to getting caught in clothing, making them difficult to grip and increasing the risk of accidental detachment, and can create pockets that lead to adhesive deterioration and leakage.

Innovation Solution

A pulling tab is integrated into the ostomy base plate, folding back at an angle of less than 90° from the backing layer, allowing for easier gripping and reducing the risk of catching, while also eliminating pocket formation between the tab and skin.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the pulling tab extends as an extension from the peripheral edge of the base plate, then it is easy to grip for removal, but it is prone to get caught in clothes and creates pockets between the tab and skin

Engineering Contradiction:

Improveease of gripping pulling tabVSAvoidrisk of getting caught in clothes

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

Instead of extending the pulling tab outward from the peripheral edge of the base plate, the invention folds the pulling tab back onto the base plate itself. This inversion of the traditional design eliminates the protruding element that catches on clothes while maintaining the tab's functionality for gripping and removal.

Inventive Principle:

Principle #13The other way round (Inversion)

2Ease of operation

If the pulling tab extends from the base plate as a single exposed part, then it provides a clear gripping surface, but it creates pockets that collect moisture and deteriorate adhesive

Engineering Contradiction:

Improvegripping surface availabilityVSAvoidadhesive durability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The pulling tab is folded back onto the base plate instead of extending outward, which eliminates the pocket formation between the tab and skin that would otherwise collect moisture and compromise adhesive reliability.

Inventive Principle:

Principle #13The other way round (Inversion)

3Ease of manufacture

If the pulling tab is arranged flush with the skin, then it is less visible and more comfortable, but it becomes difficult to grip for removal

Engineering Contradiction:

Improvediscreet appearanceVSAvoidease of gripping pulling tab

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

The pulling tab utilizes the surface dimension of the base plate by folding back onto it, creating a discreet appearance while maintaining sufficient surface area for gripping. This dimensional arrangement on the base plate surface solves both the aesthetic and functional requirements.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
