Conforming Overwrap for Pessary Device Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pessary devices for urinary incontinence can be uncomfortable during insertion and removal due to their surface properties, and there is a need for an overwrap that conforms to the device for improved comfort and minimized size.
Innovation Solution
A method of conforming an overwrap to a pessary device by manipulating it to cover at least 30% to 99% of the device's outer surface, using cords or attachment points to secure it, creating a hollow structure, and ensuring the overwrap is non-expandable to maintain the same size during use and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the overwrap is made expandable to accommodate body movements, then comfort during use improves, but the device size increases during removal
Solution Approach 1:
The overwrap employs dynamic dimensional changes: it expands during insertion to accommodate the pessary device and body movements, then contracts to a minimized size during removal. This dynamic behavior allows the overwrap to provide comfort during use while reducing resistance during removal.
2Ease of operation
If the overwrap covers more surface area of the pessary device, then comfort during insertion and use improves, but the device volume increases
Solution Approach 1:
The overwrap is constructed as a thin, flexible film that conforms tightly to the pessary device surface. This thin-film design provides comprehensive surface coverage for comfort during insertion and use while minimizing the additional volume added to the device.
