Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals with ileostomy or colostomy procedures or fecal incontinence require a flow control and collection device that is leak-proof, easy to install, operate, and remove, and does not accidentally separate.
Innovation Solution
A flow control device with a tubular member and a collection bag system featuring interlocking adapters and adjustable diameters, along with an expandable membrane and balloon valve for secure sealing and easy attachment to body openings, ensuring reliable containment of human excretions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flow control and collection device is designed to be leak-proof and secure, then reliability is improved, but device complexity increases
Solution Approach 1:
The device is divided into separate functional components: a tubular member for insertion into the body opening, an adapter with interlocking features for secure attachment, and a collection bag with a corresponding adapter. This segmentation allows each component to be optimized for its specific function while maintaining overall reliability through their coordinated interaction.
Solution Approach 2:
The adapter with interlocking features is integrated within or attached to the tubular member, and the collection bag adapter connects to this same adapter. This nested arrangement ensures that multiple security features (interlocking mechanisms, seals) are concentrated at the connection point, providing leak-proof performance without distributing complexity throughout the entire device.
2Reliability
If a flow control and collection device is designed to be secure and prevent accidental separation, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The interlocking features are designed to be dynamically engageable and disengageable. The adapter includes protrusions that fit into recesses, and these features can be easily engaged by simple pushing or twisting motions during installation, and equally easily disengaged during removal. This dynamic design provides secure attachment during use while maintaining ease of operation.
3Adaptability or versatility
If a flow control device is designed with adjustable diameter to fit body openings, then adaptability is improved, but device complexity increases
Solution Approach 1:
Rather than making the entire tubular member adjustable in diameter, only the adapter portion incorporates adjustment mechanisms. The tubular member itself maintains a fixed diameter optimized for insertion, while the adapter can be adjusted to match different body opening sizes. This partial adjustment approach provides adaptability without adding excessive complexity to the entire device.

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 generally outwardly extending flange may be configured at the outer end of the tubular member. The flange may be configured with an inflatable membrane having an inflated position wherein at least a portion of the inflatable membrane extends generally outwardly from the flange.
