Ostomy Coupling System Recessed Adhesive Low Profile
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ostomy appliances with two-piece designs face challenges in providing a low-profile, leakage-free coupling system that is easy to assemble and disconnect without causing discomfort or skin irritation, while also allowing for easy pouch replacement and visibility of the stoma.
Innovation Solution
A coupling system comprising a wafer part with a guide means and a shallow landing zone, a pouch part with a guide adapted to engage with the landing zone, and an adhesive layer recessed within the guide to adhere to the landing zone, allowing for secure and leak-proof attachment without protruding significantly from the body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional two-piece ostomy appliance coupling system is used to allow pouch replacement, then pouch replacement ease is improved, but the coupling system protrudes from the body and creates visible bulges
Solution Approach 1:
The adhesive layer is nested within a recess formed between the guide means and the body surface, creating a low-profile coupling system that does not protrude significantly from the body while maintaining secure pouch attachment and replacement capability
2Reliability
If a secure coupling system is used to prevent leakage, then leakage prevention is improved, but the coupling system becomes more complex and difficult to assemble
Solution Approach 1:
The adhesive layer is pre-positioned within the recess during manufacturing, and the guide means and guide features are pre-configured to automatically align the pouch part with the wafer part during assembly, ensuring secure attachment without requiring complex assembly procedures
Solution Approach 2:
The adhesive layer acts as an intermediary element between the pouch part and wafer part, providing secure attachment and leakage prevention while simplifying the overall coupling mechanism through a single effective bonding interface
3Strength
If the adhesive layer is exposed on the surface for strong bonding, then bonding strength is improved, but the coupling system protrudes from the body
Solution Approach 1:
The adhesive layer is nested within a recess formed between the guide means and the body surface, creating a low-profile coupling system that does not protrude significantly from the body while maintaining secure pouch attachment and replacement capability
