Ostomy Bag Adapter Interlocking Keys and Keyways
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ostomy and incontinence management devices often leak or accidentally separate, are complex to install, and lack simplicity in operation and removal, failing to meet the needs of individuals requiring ostomy procedures or experiencing fecal incontinence.
Innovation Solution
A flow control and collection system featuring a tubular member with a device adapter having radially spaced keyways and a collection bag with radially spaced keys, allowing for secure interlocking and easy connection, preventing leakage and accidental separation, and designed for simple installation and use in body openings like stomas or the anus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing ostomy and incontinence management devices are used, then flow control is provided, but leakage and accidental separation occur
Solution Approach 1:
The device is divided into separate components (collection bag with adapter, and ostomy device with adapter) that can be independently manufactured and assembled. The adapters are further segmented into specific interlocking features (keys and keyways) that provide secure connection while maintaining overall device simplicity
Solution Approach 2:
The interlocking features are nested within the adapter structures, with keys embedded in one adapter and corresponding keyways formed in the other adapter. This nesting provides a secure mechanical interlock that prevents leakage and accidental separation without requiring complex external mechanisms
2Ease of operation
If existing ostomy and incontinence management devices are used, then flow control is provided, but installation and operation are complex
Solution Approach 1:
The connection mechanism is segmented into distinct interlocking features (keys and keyways) that provide clear alignment and engagement guidance during installation, making the connection process intuitive and simple while ensuring secure attachment
Solution Approach 2:
The interlocking features are designed to self-align and self-lock during the connection process. The keys naturally guide into the keyways, and the mechanical interlock automatically secures the adapters together without requiring additional fastening steps or complex manipulation by the user
3Reliability
If existing ostomy and incontinence management devices are used, then flow control is provided, but accidental separation occurs
Solution Approach 1:
The connection has dynamic characteristics that provide stability during normal use (preventing accidental separation) while allowing controlled disconnection when intentionally activated. The interlocking features maintain rigid engagement under normal conditions but can be deliberately disengaged through a simple removal action

AI summary
A flow control and collection system includes a flow control device having a tubular member in which an inflatable balloon is positioned about the circumference of the interior side wall for closing the passageway to movement of matter and liquid when the balloon is expanded and allowing flow when the balloon is contracted against the side wall to which it is attached. The flow control device includes an adapter at the outer end of the tubular member having one or more interlocking features. A waste collection bag has a sealed body with at least one opening and a flow control device adapter at the opening having one or more counterpoising interlocking features to removably lock the adapters together and passes waste material and liquid through the flow control device into the waste collection bag.
