Pressurized Gas Tank Neck Reinforcement for Higher Torque Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressurized gas tanks face challenges in increasing torque resistance between the end-piece and the liner without increasing overall dimensions or slowing down the manufacturing process, while also dealing with complex and time-consuming concave zones that complicate mechanical strength measurement.
Innovation Solution
A tank design incorporating a reinforcement ring rigidly connected to the neck of the liner, with fastening means to secure the end-piece, enhancing torque resistance without increasing dimensions, and featuring communication means to balance pressure and improve sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the axial span of the neck of the liner is increased to increase torque resistance, then the connection strength between end-piece and liner is improved, but the overall dimensions of the tank increase
Solution Approach 1:
The invention transitions from increasing axial span (one dimension) to increasing radial thickness of the neck (another dimension). The neck's radial thickness is increased to provide greater connection surface area between the end-piece and liner, thereby increasing torque resistance without extending the axial length of the tank.
2Productivity
If the manufacturing speed is increased to improve productivity, then the manufacturing time is reduced, but the torque resistance of the connection decreases
Solution Approach 1:
The neck of the liner is pre-formed with increased radial thickness during the liner manufacturing process (by injection or rotational molding), so that the enhanced connection strength is built-in before the filament winding process begins. This allows high-speed filament winding without compromising connection strength, as the robust neck geometry is already in place.
3Volume of moving object
If concave zones are created in the liner to reduce dead volume, then the internal volume utilization is improved, but the mechanical strength measurement becomes more complex
Solution Approach 1:
The invention segments the liner structure by separating the functional zones: the concave zone is created for volume optimization while the neck region is separately designed with increased radial thickness for strength. This segmentation allows the concave zone to reduce dead volume without compromising the mechanical strength measurement, as the critical neck area remains distinct and measurable.

AI summary
A tank for containing a pressurized gas includes a liner made of plastic material and having the general shape of a cylinder with a main axis. The liner includes a neck surrounding an axial opening of the liner; an end-piece at least partially formed in the neck of the liner; a reinforcement ring provided for reinforcing the neck of the liner and being rigidly connected to and non-detachable from the neck of the liner; and a fastening device for fastening the end-piece to the ring for reinforcing the neck of the liner.
