Filament Winding Phase Adjustment for Equal Fiber Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional filament winding devices with fiber bundle guides arranged in multiple lines along the transport direction of a liner struggle to maintain equal intervals of fiber bundle winding when the winding angle changes.
Innovation Solution
A filament winding device with a phase adjusting mechanism that allows the second helical head to adjust its position between the fiber bundle guides of the first helical head, enabling the fiber bundles to be wound at equal intervals by adjusting the phase difference between the two helical heads based on the winding angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If fiber bundle guides are arranged in multiple lines along the transport direction of the liner, then a large number of fiber bundle guides can be provided, but the fiber bundle cannot be wound around the outer peripheral surface of the liner at equal intervals when the winding angle changes
Solution Approach 1:
The patent applies the dynamics principle by making the second helical head movable along the transport direction of the liner. The phase adjusting mechanism enables dynamic repositioning of the second helical head relative to the first helical head, allowing the system to adapt to different winding angles and maintain equal winding intervals. This dynamic adjustment capability resolves the contradiction by enabling both a large number of fiber bundle guides and equal winding intervals under varying conditions.
Solution Approach 2:
The patent applies the parameter changes principle by adjusting the phase difference parameter between the first and second helical heads based on the winding angle. The phase adjusting mechanism changes the positional parameter of the second helical head along the transport direction, allowing the system to optimize the winding interval equality for different winding angles while maintaining a large number of fiber bundle guides.
2Manufacturing precision
If a guide support device moves and rotates fiber bundle guides to provide them radially, then fiber bundles can be wound at equal intervals, but the device structure becomes complicated
Solution Approach 1:
The patent applies the segmentation principle by dividing the fiber bundle guiding function into two separate helical heads, each with its own fiber bundle guides. Instead of using a single complex guide support device to move and rotate all guides, the system segments the guiding function across two fixed helical heads, simplifying the overall device structure while maintaining equal winding intervals through phase adjustment between the segmented heads.
Solution Approach 2:
The patent applies the dynamics principle by introducing a movable second helical head that can be repositioned along the transport direction. This dynamic adjustment capability replaces the need for complex moving and rotating mechanisms in a single guide support device, achieving winding interval equality through phase adjustment rather than through complex real-time guide movement and rotation.

AI summary
Provided is a technique which enables fiber bundles to be wound around the outer circumference surface of a liner at equal intervals even when the winding angle of the fiber bundles changes. A filament winding device (100) provided with: a first helical head (43) on which fiber bundle guides (80) are radially disposed in the periphery of a liner (1) to be transported; and a second helical head (44) which is disposed adjacent to the first helical head (43) and on which the fiber bundle guides (80) are radially disposed in the periphery of the liner (1) to be transported. The filament winding device (100) is characterized by being provided with a phase adjusting means (50) for adjusting the phase difference (PA) between the fiber bundle guides (80) on the first helical head (43) and the fiber bundle guides (80) on the second helical head (44) in accordance with the angle (θ) at which the fiber bundle (F) is wound around the liner (1).
