Detachable Urostomy Valve Closure for Secure Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing urostomy appliances lack an efficient and user-friendly mechanism for controlling the flow of liquid waste, which can lead to discomfort and inconvenience for users.
Innovation Solution
A valve system for urostomy appliances that includes a body connected to the appliance, an inlet and outlet connected by a flow path, and a movable closure arrangement that can be detached and rotated, allowing for easy control of liquid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a closure arrangement is made detachably connectable to the body, then ease of operation is improved, but reliability deteriorates due to risk of accidental detachment
Solution Approach 1:
The closure arrangement is divided into separate components: a closure body and a connection member, which are detachably connectable to the valve body. This segmentation allows the closure to be easily removed and reattached while maintaining a secure connection during use, resolving the contradiction between ease of operation and reliability.
Solution Approach 2:
The connection member is designed to be rotatable with respect to the valve body, allowing dynamic adjustment of the closure arrangement's position. This rotational capability enables the user to easily open and close the valve while maintaining secure attachment, balancing operational ease with connection reliability.
2Ease of operation
If the closure arrangement is made rotatable, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The connection member is designed with rotational capability relative to the valve body, allowing the closure arrangement to rotate for easy opening and closing operation. This dynamic feature simplifies user interaction while adding only minimal structural complexity through the rotational joint design.

AI summary
A valve for a urostomy appliance including: a body for connection to the urostomy appliance, an inlet and an outlet, connected by a flow path, and a closure arrangement which is moveable between a closed position, in which the closure arrangement blocks the outlet, such that liquid cannot flow through the outlet, and an open position in which the outlet is open, such that liquid is permitted to flow out of the outlet, wherein the closure arrangement is detachably connectable to the body.
