Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tracheostoma device holders struggle with application on non-planar surfaces, particularly sunken stomas, leading to uneven force distribution, leakage, and premature device displacement, especially with automatic speaking valves.
Innovation Solution
A tracheostoma device holder with a thermoplastic disc and surrounding plate material, allowing for customizable molding to fit various stoma shapes, combined with a tubular fitting and retaining lip for secure attachment, ensuring even force distribution and reduced leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional tracheostoma device holder is used on a non-planar surface, then the device can be attached to the skin, but the adhesive surface adheres to the walls of the pit before reaching the bottom, causing uneven force distribution and leakage
Solution Approach 1:
The plate is designed with a convex surface that matches the curved anatomy of the neck and stoma area. This curvature allows the plate to conform to the non-planar surface, ensuring the adhesive contacts the bottom of the pit rather than adhering to the walls, thereby achieving uniform force distribution and preventing leakage.
2Stability of the object's composition
If the plate is made rigid for secure attachment, then the device remains stable, but it cannot accommodate various stoma shapes and non-planar surfaces
Solution Approach 1:
The plate is designed with a convex surface that provides localized adaptation to the curved anatomy of the neck and stoma area. This local curvature allows the rigid plate to conform to various stoma shapes and non-planar surfaces while maintaining overall structural stability and secure attachment.
3Reliability
If the adhesive surface is increased to improve attachment on non-planar surfaces, then the device remains secure, but the complexity of application and force distribution increases
Solution Approach 1:
The convex surface of the plate naturally conforms to the curved anatomy of the neck and stoma area, providing adequate adhesive contact area without requiring the adhesive to be extended or modified. This geometric design simplifies the application process while ensuring secure attachment and uniform force distribution.
