Solution Overview

Problem

Existing pressurized gas storage systems face challenges with difficult assembly and maintenance due to tanks being suspended within a recess, which puts support elements under significant load and complicates access for work on the tanks.

Innovation Solution

A pressurized gas storage system with vertically arranged tanks supported by upper and lower fixing devices, anchored to the well's side wall and/or bottom, allowing for easy assembly and simplified maintenance, with features like annular support pieces, flanges, and forced ventilation systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If tanks are suspended within the recess, then the storage system is compact, but the support elements are under significant load and access for maintenance is difficult

Engineering Contradiction:
Improvestorage system compactnessVSAvoidaccess for maintenance
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The support structure is segmented into multiple independent support elements (first support element, second support element, etc.) that can be individually accessed. Each support element can be independently removed or maintained without affecting the entire storage system, allowing maintenance personnel to access specific components while other tanks remain in place.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Assembly elements serve as intermediaries between the support elements and the tanks. These assembly elements facilitate the connection and disconnection of tanks from support elements, making it easier to remove tanks for maintenance without directly manipulating the support elements themselves.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Volume of moving object

If tanks are suspended within the recess, then the storage system is compact, but support elements are under significant load

Engineering Contradiction:
Improvestorage system compactnessVSAvoidload on support elements
Core Design Contradiction:
Volume of moving objectVSForce

Solution Approach 1:

The total load is segmented and distributed across multiple independent support elements rather than concentrating weight on single points. This distribution reduces the force burden on each individual support element while maintaining the compact suspended configuration of the storage system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple support elements work together as a unified support system, sharing the total load of all suspended tanks. The combined strength of multiple support elements collectively bears the weight, reducing the stress on any single element compared to a single-point suspension system.

Inventive Principle:
Principle #5Merging (Combining)

3Volume of moving object

If tanks are suspended within the recess, then the storage system is compact, but any work on a tank typically requires removing it from the recess

Engineering Contradiction:
Improvestorage system compactnessVSAvoidtank maintenance complexity
Core Design Contradiction:
Volume of moving objectVSEase of repair

Solution Approach 1:

The connection system is segmented into separate components: support elements, assembly elements, and tank interfaces. This segmentation allows tanks to be disconnected from support elements through the assembly elements without requiring complete removal from the recess structure, enabling in-place maintenance while preserving system compactness.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support and connection system is designed to be dynamic rather than fixed, allowing tanks to be easily attached and detached from support elements. This dynamic connection system enables maintenance operations without permanent structural changes or complete system disassembly, maintaining compactness while improving repairability.

Inventive Principle:
Principle #15Dynamics
