Asymmetric Adhesive Packaging Enclosure for Ostomy Appliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packaging enclosures for adhesive ostomy barrier rings require users to remove the barrier ring and its release liners separately, which can be cumbersome and inconvenient, especially in ostomy care settings where handling and application are critical.
Innovation Solution
A packaging enclosure with a body and upstanding sidewall formed from one material and a cover element formed from a second material with a higher affinity for the barrier ring, allowing the barrier ring to remain affixed to the cover when removed, facilitating easier handling and application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a molded clamshell enclosure is used to secure the barrier ring, then the appliance is protected and maintained in the enclosure, but the user has to remove the barrier ring and release liners separately which increases handling complexity
Solution Approach 1:
The release liner is merged with the cover element by forming the release liner from the cover material itself, creating a single integrated component. This allows the user to remove the cover element with the release liner already attached, eliminating the need for separate removal steps and reducing handling complexity while maintaining protection of the appliance.
2Ease of operation
If the cover element is formed from a material with higher affinity for the ostomy appliance than the body material, then the appliance remains affixed to the cover during removal, but the materials must be different requiring multi-material manufacturing
Solution Approach 1:
The enclosure is segmented into two distinct components: a body formed from a first material and a cover element formed from a second material with different affinity characteristics. This segmentation allows each component to be optimized for its specific function while maintaining manufacturing feasibility through separate formation processes that can be joined together.
Solution Approach 2:
The enclosure utilizes composite material construction with a body made from one material (e.g., polyethylene) and a cover element made from a different material (e.g., polypropylene or paper-based material) that has higher affinity for the adhesive appliance. This composite approach enables differential adhesion properties while maintaining structural integrity and manufacturing practicality.
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 solution reduces user handling and preparation steps by ensuring the barrier ring remains attached to the cover, making it easier to apply and use, enhancing convenience in ostomy care.
Implementation Method 1
The second material has a higher affinity for the ostomy appliance, e.g., the barrier ring, than the first material affinity for the ostomy appliance

AI summary
A packaging enclosure for an ostomy appliance includes a body having a base and an upstanding sidewall integral and contiguous with the base and having a peripheral edge opposite the base. The base and sidewall define a storage region for the ostomy appliance. The base and sidewall are formed from a first material. A cover element extends over the storage region and is formed from a second material. The second material has a higher affinity for the ostomy appliance than the first material affinity for the ostomy appliance. An ostomy appliance and packaging enclosure is also enclosed.
