Degassing Tube Bundle Structure for Higher Bundling Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The bundling strength of fluororesin tubes is limited by their cylindrical end portions, which restricts the density of the bundling structure and thus the improvement of bundling strength.
Innovation Solution
A degassing module with a tube unit that includes multiple tubes with radially protruding end portions, allowing for denser bundling and improved structural integrity, along with a housing and sealing portions to prevent fluid leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the end portions of fluororesin tubes are shaped cylindrically, then the tubes can be easily manufactured, but the bundling strength is limited due to restricted density of the bundling structure
Solution Approach 1:
The end portions of the fluororesin tubes are transformed from cylindrical symmetric shapes to asymmetric shapes with protrusions. Each tube end includes a flat portion and a protrusion that extends radially outward, creating an asymmetric geometry that enables interlocking between adjacent tubes. This asymmetric design allows the tubes to be bundled more densely and securely, significantly improving bundling strength while maintaining manufacturability through molding processes.
2Strength
If the end portions of tubes are bundled more densely to improve bundling strength, then the bundling strength increases, but the cylindrical shape limits the degree of density achievable
Solution Approach 1:
The end portion of each tube is segmented into distinct functional regions: a flat portion that provides a stable base for bundling and protrusions that extend radially outward to interlock with adjacent tubes. This segmentation of the end portion geometry enables denser packing arrangements, as the protrusions fit into spaces between adjacent tube ends, allowing achieving higher bundling density and strength.
3Strength
If protrusions are added to the end portions of tubes, then the bundling strength is improved through denser arrangement, but the device complexity increases
Solution Approach 1:
The geometry of the tube end portions is modified by changing parameters such as protrusion height, protrusion width, and the angle of the flat portion. These parameter changes enable the protrusions to interlock effectively with adjacent tubes, achieving denser bundling and improved strength. The parameters are optimized to balance the complexity of the geometry with the performance benefits, ensuring that the protrusions provide sufficient mechanical interlocking without excessive complexity.

AI summary
A tube unit includes multiple tubes and bundling portions that bundle end portions of respective tubes at opposite ends of the tubes. At least one of the end portions of respective tubes has a tube wall portion that tubularly extends in an extension direction of the tubes and also has a protrusion protruding radially outward from the tube wall portion.
