Toroidal Pressure Tank With Central Coupler For Volume And Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressure tanks face challenges in efficiently managing internal volume, material distribution, and safety during blowout, particularly due to the lack of control over the flow and direction of the working medium, and require complex welding processes for equipment installation.
Innovation Solution
A pressure tank design featuring a central coupler with multiple shells, where the external shells are connected through a central bush with circumferential narrowing, allowing for increased internal volume, reduced material usage, and controlled blowout direction, along with pointwise fixing of data plates for easier installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If equipment is welded on the outer shell, then the tank structure is simplified, but the tank volume increases and safety decreases due to earlier blowout
Solution Approach 1:
The tank is divided into multiple shells (outer shell, intermediate shell, inner shell) with equipment welded on the inner shell rather than the outer shell. This segmentation allows the outer shell to maintain structural integrity and withstand higher pressures before blowout, while the inner shell accommodates equipment without compromising overall safety.
2Ease of manufacture
If the central tube is used without filling, then the manufacturing is simpler, but the internal volume is reduced
Solution Approach 1:
The central tube is designed to be filled with the stored medium (gas or liquid), allowing it to serve dual purposes: as a structural component during manufacturing and as additional storage volume during operation. This eliminates wasted space and maximizes the tank's internal volume without requiring complex additional structures.
3Device complexity
If the central tube design is used, then the structure is simpler, but the level height of working medium increases and valve design becomes more complex
Solution Approach 1:
The patent repositions valves and connectors from the traditional central tube location to the inner shell wall, changing the spatial dimension of equipment installation. This allows valves to be mounted at optimal heights and positions on the inner shell, reducing the required level height of working medium and simplifying valve design and installation while maintaining structural simplicity.
4Weight of moving object
If material is reduced for weight savings, then the mobility is improved, but the strength and blowout resistance decreases
Solution Approach 1:
The tank employs a composite multi-shell structure where outer shell, intermediate shell, and inner shell work together as an integrated system. This composite construction distributes stress across multiple layers, providing enhanced blowout resistance and structural strength while using optimized material thickness in each shell to minimize overall weight compared to a single thick-walled design.
