Double-Layer Spiral Winding for Storage Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fiber winding molding processes for storage containers face issues with single-bundle winding causing stacking, crossing, and uneven winding, leading to stress concentration and poor production efficiency, while existing equipment limitations hinder the improvement of winding efficiency and stability.
Innovation Solution
A method involving spirally winding multiple bundles of fibers using a double-layer spiral winding structure with yarn guide nozzles and feeding devices that perform axial reciprocating motion and self-rotation, allowing for single-station double-layer or double-station single-layer winding based on container dimensions, to ensure even distribution and reduce yarn slippage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If single-bundle fiber winding is used, then the winding process is simple, but fiber stacking and crossing occur causing stress concentration and reduced strength
Solution Approach 1:
The patent divides the single winding process into multiple independent bundles (first bundle and second bundle) that wind simultaneously on different layers. This segmentation allows each bundle to wind independently without stacking and crossing, eliminating stress concentration while maintaining process simplicity through coordinated control of multiple bundles.
2Productivity
If multi-station synchronous winding is used to improve production efficiency, then winding speed increases, but equipment complexity increases and space limitations prevent further efficiency improvement
Solution Approach 1:
The patent merges multiple winding operations into a single station by implementing double-layer simultaneous winding with multiple fiber bundles. Instead of using multiple stations sequentially, the system combines first and second bundles to wind different layers at the same time in one station, achieving multi-station productivity with single-station simplicity, thus avoiding equipment complexity and space limitations.
3Ease of manufacture
If traditional spiral winding is used, then the winding process is straightforward, but uneven winding occurs reducing fatigue life and durability
Solution Approach 1:
The patent transitions from single-layer winding to double-layer simultaneous winding by adding a vertical dimension to the winding process. The first and second bundles wind different layers at the same time, creating uniform stress distribution across multiple layers. This dimensional expansion eliminates uneven winding and stress concentration, improving fatigue life while maintaining ease of manufacture through coordinated control.
