Urostomy Valve Closure for Secure Detachment and Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing urostomy and ileostomy appliances face challenges in efficiently managing the flow of liquid and solid waste, with traditional valves being uncomfortable and prone to accidental detachment, especially when used for extended periods.
Innovation Solution
A valve system for urostomy appliances featuring a moveable closure arrangement with detachable and rotatable connection members, incorporating a bung portion for secure closure and a smooth transition design, ensuring comfort and preventing accidental detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional valves are used in urostomy appliances, then the valve can provide basic waste flow control, but the valve becomes uncomfortable and prone to accidental detachment during extended use
Solution Approach 1:
The valve closure arrangement is divided into separate components: a closure member that can be detached from the valve body. This segmentation allows the closure member to be removed for cleaning or replacement while maintaining secure attachment during use, addressing both reliability and ease of operation requirements
Solution Approach 2:
The closure arrangement transitions from a static attached state to a dynamic detachable state. The closure member can be securely attached during normal operation and then detached when needed for cleaning or disposal, providing adaptability throughout the extended use period
2Ease of repair
If the valve closure arrangement is made detachable for cleaning and maintenance, then ease of repair and cleaning is improved, but the risk of accidental detachment during normal operation increases
Solution Approach 1:
The closure member is pre-designed with a detachable connection mechanism that allows easy removal for cleaning or replacement. This preliminary design consideration enables maintenance activities without requiring disassembly of the entire valve assembly, improving ease of repair while maintaining secure attachment during normal use through proper connection design
