Solution Overview

Problem

Existing devices fail to effectively prevent the development and appearance of parastomal hernias in ostomized patients, as they are either uncomfortable, prone to displacement, or primarily designed for containing effluent rather than providing comprehensive support and prevention.

Innovation Solution

A device comprising a rigid ostomy base with a curved central section and thicker end sections, equipped with elastically compressible coatings and antislip adhesive surfaces, paired with a flexible and elastic securing strap featuring Velcro attachments, designed to provide stable and uniform pressure around the stoma area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing compression devices are used, then hernia containment is attempted, but the devices are uncomfortable and prone to displacement

Engineering Contradiction:
Improvehernia prevention effectivenessVSAvoidpatient comfort and device stability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The device is divided into distinct functional segments: a rigid bridge-shaped base structure for anatomical support, elastically compressible coatings for gentle pressure distribution, and Velcro securing means for stable attachment. This segmentation allows each component to optimize its specific function while maintaining overall comfort and effectiveness.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the device have different properties tailored to local requirements: the central bridge section provides rigid structural support where hernia prevention is critical, while the end sections feature elastically compressible coatings for comfortable skin contact, and Velcro attachments are positioned for optimal securing without discomfort.

Inventive Principle:
Principle #3Local quality

2Adaptability or versatility

If existing ostomy devices are used, then effluent containment is provided, but hernia prevention is not effectively addressed

Engineering Contradiction:
Improvedevice functionalityVSAvoidhernia prevention capability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The device combines multiple functions into a single integrated system: the rigid bridge-shaped base provides both ostomy support and hernia prevention, the elastically compressible coatings provide both comfort and gentle compression for hernia containment, and the Velcro securing means ensures stable attachment while accommodating movement.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If compression garments are used, then physical support is provided, but the garments are uncomfortable during use

Engineering Contradiction:
Improvephysical support for herniaVSAvoidcomfort during use
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The device changes the compression parameter from the traditional hard, uniform pressure of compression garments to a softer, elastically compressible pressure that adapts to body contours. The elastically compressible coatings provide gentle, distributed pressure that maintains hernia support while significantly improving comfort during prolonged wear.

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The device effectively prevents the development of parastomal hernias by providing stable and comfortable support, ensuring the ostomy area is covered with uniform pressure without excessive compression, allowing easy application and adjustment for improved patient tolerance.

Implementation Method 1

end sections (3 and 4) have a greater thickness than the central section (2) and can protrude through its external surface with respect to the convex surface of the central section. According to a preferred embodiment, the end sections of the ostomy base are equipped, on their internal surface, with an elastically compressible coating

Methodology Applied
Scientific EffectElastic compression: Elasticity

Implementation Method 2

The end sections of the ostomy base will preferably be equipped on their external surface with an antislip and preferably adhesive coating

Methodology Applied
Scientific EffectFriction: Friction

Implementation Method 3

The end sections of the ostomy base will preferably be equipped on their external surface with an antislip and preferably adhesive coating, for example Velcro

Methodology Applied
Scientific EffectAdhesion: Adhesive
