Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filament winding apparatuses face challenges in achieving intended helical winding of fibers around a liner surface, leading to potential gaps or overlaps, which affect the coverage and thickness of the reinforcing layer.
Innovation Solution
A filament winding apparatus with N guide members arranged around a liner, where each guide member supplies one bundle of fibers and a drive unit repeats a winding operation to achieve a specific winding angle and position, ensuring the fibers are wound at intended positions and covering the entire surface with controlled overlap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If bundles of fibers are wound helically around the liner using multiple guide members, then the liner surface coverage is improved, but the winding precision and intended pattern achievement deteriorate due to potential gaps or overlaps
Solution Approach 1:
The fiber bundle supply system is segmented into multiple independent guide members (at least two), each supplying fiber bundles to different regions of the liner. This segmentation allows simultaneous winding operations on different portions of the liner, improving overall coverage while maintaining precise control over each individual guide member's winding path and tension, thereby preventing gaps and overlaps.
2Area of stationary object
If the sum of coverage rates of multiple fiber bundles is set within 100%-110%, then the entire liner surface is covered, but the reinforcing layer thickness control becomes challenging
Solution Approach 1:
Each guide member is assigned a specific coverage rate range (50-60% individually) to achieve uniform local distribution of fiber bundles across the liner surface. This local quality control ensures that while the total coverage reaches 100-110%, the fiber bundles are evenly distributed without excessive concentration in any region, thereby maintaining uniform reinforcing layer thickness and preventing localized gaps or overlaps.
3Productivity
If multiple guide members are used to supply fiber bundles, then the winding operation efficiency is improved, but the system complexity increases
Solution Approach 1:
Multiple guide members are merged into a coordinated system where each guide member operates independently but follows the same control logic and winding parameters. This merging approach allows parallel winding operations that improve productivity while maintaining manageable system complexity through standardized guide member design and unified control strategies.
4Productivity
If fiber bundles are wound with high coverage rate, then the manufacturing time is reduced, but the fiber feeding amount increases excessively
Solution Approach 1:
The system employs partial overlap of fiber bundles from different guide members, with the sum of coverage rates set to 100-110%. This partial excessive action ensures complete coverage of the liner surface without requiring excessive fiber feeding, as the overlap is carefully controlled to fill gaps rather than create excessive redundancy, thereby maintaining efficient manufacturing speed with moderate material consumption.
