Filament Winding Guide Unit Dynamics for Curved Cores
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filament winding apparatuses are not capable of efficiently winding fiber bundles onto core materials with curved or complex shapes, as they lack the necessary flexibility and adaptability to adjust to the shape of the core material during the winding process.
Innovation Solution
A filament winding apparatus with a rail and core material support system that includes a guide unit mounted on a main frame, which is movable and rotatable to adjust its position and orientation relative to the core material, allowing for precise winding of fiber bundles onto curved or complexly shaped core materials. This apparatus utilizes multiple drive sources and a control device to maintain the guide unit's posture in sync with the core material's shape, enabling three-dimensional winding capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed winding device is used for linear core materials, then the winding process is simple, but the apparatus cannot handle curved or complexly shaped core materials
Solution Approach 1:
The guide unit is mounted on a main frame that can move in multiple directions (first direction along the rail, second direction perpendicular to the rail) and rotate around a first rotational axis. This dynamic positioning capability allows the guide unit to adapt to curved and complexly shaped core materials, resolving the contradiction between adaptability and device complexity by introducing controlled mobility rather than fixed positioning.
Solution Approach 2:
The main frame is configured to move not only in the first direction (along the rail) but also in a second direction orthogonal to the first direction, and can rotate around a first rotational axis extending in a third direction. This multi-dimensional movement capability enables the winding device to access and wind fiber bundles onto three-dimensionally curved core materials, transforming a one-dimensional winding process into a multi-dimensional operation.
2Manufacturing precision
If the guide unit position is fixed, then the device structure is simple, but the fiber bundle cannot be properly wound onto curved portions of the core material
Solution Approach 1:
The guide unit's mounting on a movable main frame enables dynamic adjustment of the guide unit's position and orientation during the winding process. This allows the system to maintain precise fiber placement on curved portions of the core material by continuously adapting the guide unit's position, rather than relying on a fixed structure that would compromise precision on non-linear surfaces.
Solution Approach 2:
The control device coordinates the movement of the main frame in the first and second directions, as well as its rotation around the first rotational axis, to maintain the guide unit's opening centered on the core material throughout the winding process. This feedback-controlled positioning ensures manufacturing precision is maintained even as the guide unit adapts to curved geometries.
