Solution Overview
Problem
Current multi-bundle winding equipment for high-pressure hydrogen storage vessels has issues with large occupied space, complex control systems, and low winding efficiency due to the separation of spiral and hoop winding units, leading to high development and production costs.
Innovation Solution
Integrated spiral and hooping winding equipment that couples a spiral winding unit and a hoop winding unit with a shared gear system, featuring a ring-shaped guide plate, transmission gear rings, and electromagnetic pressure springs to improve efficiency and reduce space and cost, allowing for synchronous radial feeding and rotation motions without affecting each other.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multi-bundle spiral winding equipment and hoop winding equipment are separated, then each unit can be independently designed and manufactured, but the occupied space increases and winding efficiency decreases
Solution Approach 1:
The patent combines separate spiral winding equipment and hoop winding equipment into a single integrated machine. The spiral winding unit and hoop winding unit share common components including a shared gear system, control system, and base structure. This merging eliminates the need for two separate machines, reducing occupied space while enabling coordinated operation to improve winding efficiency through better process integration.
Solution Approach 2:
The integrated equipment is designed with multi-functional capabilities where a single machine can perform both spiral winding and hoop winding operations. The shared gear system and control mechanisms allow the equipment to switch between different winding modes, making the system versatile and eliminating the need for dedicated separate machines for each winding type.
2Ease of repair
If multi-bundle spiral winding equipment and hoop winding equipment are separated, then each unit can be independently maintained, but the occupied space increases and control complexity increases
Solution Approach 1:
The patent merges the control systems of spiral and hoop winding units into a unified control architecture. A single control unit coordinates both winding operations, reducing the overall number of control components and simplifying the control logic compared to having separate control systems. This integrated control approach reduces device complexity while maintaining the ability to perform both winding types.
3Device complexity
If single-bundle winding is used, then equipment structure is simple, but winding efficiency is low and fiber stress concentration occurs
Solution Approach 1:
The patent employs multiple fiber feeding mechanisms arranged in a circumferential array around the winding drum. Each mechanism feeds a separate fiber bundle, allowing multi-bundle simultaneous winding. This segmentation of the fiber feeding system enables multiple bundles to be wound at the same time, significantly improving winding efficiency and distributing fiber stress more evenly compared to single-bundle winding.
