Zigzag Frame Balloon Synchronization for Stable Dilation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inflatable dilatation devices with a tubular frame and inflatable balloon are insufficiently stable during expansion, as the balloon requires additional stabilization or links to maintain contact with the frame, leading to relative movement issues.
Innovation Solution
A tubular frame with a first member that zigzags circumferentially, secured to a zigzagging inflatable balloon, ensuring that both expand in unison without significant relative movement, with additional frame members extending longitudinally and balloons adhered to the frame at multiple points for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the balloon is secured to the frame alone, then the device structure is simple, but the balloon is insufficiently stable during expansion
Solution Approach 1:
The balloon is divided into multiple segments or zones, with different portions secured to different frame members. This segmentation allows each portion to be stabilized independently while maintaining overall structural simplicity, resolving the contradiction between simple structure and balloon stability during expansion.
2Stability of the object's composition
If additional links are added to stabilize the balloon, then the balloon stability is improved, but the device complexity increases
Solution Approach 1:
The stabilization function is merged with the existing frame structure by securing multiple portions of the balloon to different frame members. This integration eliminates the need for separate stabilization links, achieving balloon stability without increasing device complexity.
3Stability of the object's composition
If the balloon and frame expand in unison, then the relative movement between balloon and frame is reduced, but the manufacturing precision requirements increase
Solution Approach 1:
Different portions of the balloon are secured to different frame members at specific locations, allowing each secured portion to expand in unison with its corresponding frame member. This localized approach to securing the balloon reduces relative movement while managing manufacturing precision requirements through strategic placement rather than uniform high-precision requirements throughout.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides stable expansion of the dilatation device by minimizing relative movement between the balloon and frame, eliminating the need for additional stabilization links and ensuring the balloon is supported by the frame alone, thereby maintaining stability during inflation.
Implementation Method 1
an elongate inflatable first balloon that: is secured to the first frame member; and zigzags along the first frame member, such that inflation of the first balloon causes the first balloon and the first frame member circumferentially to expand in unison from a contracted condition to an expanded condition
