Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for forming full-composite material pressure vessels are inefficient and costly, particularly in producing V-shaped vessels without the need for a dissolvable liner mold.
Innovation Solution
A device and method for forming a V-shaped full-composite pressure vessel using a semi-cylinder body mold, a fiber yarn-dividing ring, and a valve seat, where the mold is connected to the valve seat through a spline and the fiber yarn-dividing ring is threaded to a rotating shaft of fiber winding equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a dissolvable liner mold is used to form V-shaped full-composite pressure vessels, then the vessel can be formed without a permanent liner, but the production efficiency is low and cost is high due to the need to dissolve and remove the mold
Solution Approach 1:
The mold is divided into two separate semi-cylinder body molds that can be independently assembled and disassembled. This segmentation allows the molds to be easily separated after curing without requiring dissolution, thereby improving production efficiency while maintaining the ability to form V-shaped full-composite pressure vessels
Solution Approach 2:
A valve seat component serves as an intermediary element that connects the two semi-cylinder body molds together during the forming process. This intermediary structure enables the molds to be assembled and disassembled as a complete unit without requiring chemical dissolution, resolving the contradiction between ease of manufacture and productivity
2Shape
If a dissolvable liner mold is used to form V-shaped full-composite pressure vessels, then the vessel structure can be achieved, but the production cost increases due to the complexity of the dissolving and removal process
Solution Approach 1:
The mold system is segmented into two semi-cylinder body molds that can be assembled around the valve seat to form the complete V-shaped structure. This segmentation eliminates the need for complex dissolvable materials and dissolution processes, maintaining the V-shaped structure capability while significantly reducing production costs
Solution Approach 2:
The invention replaces expensive dissolvable liner molds with reusable semi-cylinder body molds that are assembled temporarily for each forming operation. These molds can be disassembled and reused multiple times, eliminating the high costs associated with dissolvable materials and their removal processes while maintaining the ability to form complex V-shaped structures

AI summary
A device for forming a V-shaped full-composite pressure vessel includes a semi-cylinder body mold, where the length of a cylinder body part of the semi-cylinder body mold is half of the length of a cylinder body of a processed pressure vessel; a groove for placing a valve seat is reserved at one end of a dome part of the semi-cylinder body mold, and a fiber yarn-dividing ring is mounted at the other end; the semi-cylinder body mold is connected to the valve seat through a spline; and the valve seat and the fiber yarn-dividing ring are in threaded connection with a rotating shaft of fiber winding equipment. According to this disclosure, a liner-free pressure vessel can be manufactured completely by processing a composite material, so the mass of the pressure vessel can be reduced. Furthermore, the mold is not required to be dissolved and taken out.
