Filament Winding Method Using Segmented Fiber Bundle Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional filament winding methods require unnecessary easy winding and combination winding steps, leading to increased time and fiber usage, which elevates manufacturing costs due to the continuous connection of hoop-wound fiber bundles to the liner surface without proper cutting.
Innovation Solution
The method involves fixing the fiber bundle end to the liner surface at the starting position of hoop winding, cutting it at the ending position, and using a fixation mechanism with a heater to secure the bundle, eliminating the need for easy winding and combination winding by ensuring continuous hoop and helical winding without fiber bundle detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the hoop winding device is moved to the retreated position with the fiber bundle still connected to the liner surface, then the fiber bundle remains continuously connected without manual fixing, but the fiber bundle requires unnecessary easy winding and combination winding steps which increases time and fiber usage
Solution Approach 1:
The fiber bundle is segmented into two independent parts: a first fiber bundle for hoop winding and a second fiber bundle for helical winding. The first fiber bundle is cut from the second fiber bundle at a predetermined position, allowing the hoop winding device to move to the retreated position without requiring easy winding and combination winding operations, thus reducing time loss while maintaining continuous connection capability
Solution Approach 2:
The first fiber bundle is preliminarily fixed to the liner surface at the starting position of hoop winding before the actual hoop winding begins. This preliminary fixation eliminates the need for subsequent easy winding and combination winding steps, reducing the time required for hoop winding operations while maintaining the continuous connection advantage
2Ease of operation
If easy winding and combination winding are performed to move the fiber bundle from the retreated position to the hoop winding starting position, then the fiber bundle can be properly positioned, but the fiber bundle is excessively used and manufacturing cost increases
Solution Approach 1:
The fiber supply system is segmented into a first fiber bundle and a second fiber bundle, with the first fiber bundle being cut from the second at a predetermined position. This segmentation allows the first fiber bundle to be used efficiently for hoop winding without requiring excessive length for easy winding and combination winding, thus reducing fiber loss and manufacturing cost while maintaining proper positioning
Solution Approach 2:
The first fiber bundle is extracted or cut from the second fiber bundle at a predetermined position before hoop winding begins. This extraction eliminates the need for the first fiber bundle to be excessively long to accommodate easy winding and combination winding operations, reducing fiber consumption and manufacturing cost while still allowing proper positioning through the fixation mechanism
3Ease of operation
If the hoop winding device is moved while carrying out easy winding, then the fiber bundle can be wound during movement, but the easy-wound fiber bundle is not involved in the formation of the reinforcement layer and adds unnecessary complexity
Solution Approach 1:
The winding process is segmented into distinct phases: first fiber bundle for hoop winding, second fiber bundle for helical winding, with a cut at the predetermined position. This segmentation separates the hoop winding operation from the helical winding operation, eliminating the need for easy winding and combination winding steps, thus reducing process complexity while maintaining the ability to move the hoop winding device during operation
Solution Approach 2:
The easy winding and combination winding steps are extracted or removed from the winding process by using the segmented fiber bundle approach. The first fiber bundle is cut from the second bundle, allowing the hoop winding device to move during hoop winding without requiring easy winding and combination winding operations, thus simplifying the overall process while maintaining operational flexibility

AI summary
A filament winding method performs a hoop winding step including a first step of fixing an end of a fiber bundle to a liner surface at a starting position of hoop winding, a second step of hoop winding the fiber bundle having the end fixed to the liner surface in the first step, a third step of fixing the fiber bundle hoop wound in the second step to the liner surface at an ending position of hoop winding, and a fourth step of cutting the fiber bundle upstream in a fiber bundle supplying direction of the position where the fiber bundle is fixed in the third step.
