Solution Overview

Problem

Existing ostomy bag changing devices are bulky, uncomfortable, and lack secure disposal bag attachment, leading to hygiene issues and difficulty in changing or emptying bags independently, especially in confined spaces or when mobility is limited.

Innovation Solution

A frame with secure disposal bag attachment points and a support structure that can be belted to the user, ensuring the disposal bag remains open and stable during use, minimizing the risk of spillage and providing ergonomic support.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a bulky collection vessel with hinged flap and curved ramped portion is used, then the disposal bag can be positioned within the collection vessel, but the device becomes bulky and difficult to carry around

Engineering Contradiction:
Improvedisposal bag positioningVSAvoiddevice size
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The patent removes the bulky collection vessel and curved ramped portion from the device, extracting only the essential frame structure. The disposal bag is secured directly to the frame using attachment points, eliminating the need for a separate collection vessel while maintaining reliable bag positioning.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent uses a lightweight frame structure with attachment points instead of a bulky rigid collection vessel. The disposal bag itself serves as the containment element, secured to the frame, which reduces overall device volume while maintaining functionality.

Inventive Principle:
Principle #30Flexible shells and thin films

2Ease of operation

If the support structure extends downwards from the main body section, then the device provides ergonomic support and stability, but the device complexity increases

Engineering Contradiction:
Improveergonomic supportVSAvoidsupport structure design
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The support structure is divided into two segments: a main body section that attaches to the belt and a downward-extending section that provides ergonomic support. This segmentation allows each part to perform its specific function while keeping the overall design simple and modular.

Inventive Principle:
Principle #1Segmentation

3Stability of the object's composition

If the frame has secure disposal bag attachment points, then the disposal bag remains stable and open during use, but the device complexity increases

Engineering Contradiction:
Improvedisposal bag stabilityVSAvoidframe attachment system
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The attachment points for the disposal bag are integrated directly into the frame structure, merging the securing function with the frame itself. This eliminates the need for separate complex securing mechanisms while maintaining bag stability and open position during use.

Inventive Principle:
Principle #5Merging (Combining)
