High Pressure Tank Inspection Sequence for Efficient Manufacturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for manufacturing tank units with high pressure tanks are inefficient due to the time-consuming pressure resistance inspection process, which is prolonged by the large gas flow path losses when water is injected for inspection after the gas flow path is attached.
Innovation Solution
Performing a pressure resistance inspection on each high pressure tank before attaching the gas flow path, allowing for quicker drying and connection of the tanks using top and bottom connectors, and ensuring all tanks are contained within a protective rectangular parallelepiped structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If water is injected into the high pressure tank for pressure resistance inspection after the gas flow path is attached, then the inspection can be performed on the complete assembly, but it takes time to perform the inspection due to large loss in the gas flow path
Solution Approach 1:
The pressure resistance inspection is performed on the high pressure tank before the gas flow path is attached. This preliminary action allows the inspection to be completed without the time-consuming water removal process, as the tank is inspected in isolation before final assembly. The gas flow path is then attached after the inspection is complete, eliminating the time loss associated with draining and drying the system.
2Reliability
If the gas flow path is attached before pressure resistance inspection, then the complete system can be tested, but the inspection time increases due to large loss in the thinner gas flow path
Solution Approach 1:
The pressure resistance inspection is conducted as a preliminary step before attaching the gas flow path. This sequence ensures that the high pressure tank is verified for integrity before final assembly, and avoids the need to drain and dry the thinner gas flow path, which would significantly extend the manufacturing cycle time.
Solution Approach 2:
The inspection process is segmented into separate stages: first inspecting the high pressure tank in isolation, then attaching the gas flow path separately. This segmentation allows each component to be tested independently, avoiding the time penalty of testing the complete assembled system where water would need to be removed from all components including the narrow gas flow path.

Function Achieved in This Case
This method enables efficient manufacturing by reducing inspection time and ensuring the high pressure tanks are quickly dried and securely connected, enhancing protection and assembly efficiency.
Implementation Method 1
Dry air having entered the high pressure tank through the opening in the top passes through the inside of the high pressure tank and leaves the high pressure tank through the opening in the bottom

AI summary
A method for manufacturing a tank unit includes performing a pressure resistance inspection on each of a plurality of high pressure tanks before connecting the high pressure tanks, and connecting a gas flow path to the high pressure tanks that have passed the pressure resistance inspection.
