Solution Overview

Problem

Existing inflatable structures are inadequate for storing large volumes of gas across various environmental conditions, particularly for gases like CO2, as they lack the necessary durability and adaptability to withstand extreme weather and meet industry standards for safety and efficiency.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a single-layer inflatable structure is used, then the structure is simple and easy to manufacture, but it cannot withstand extreme weather conditions and has poor durability

Engineering Contradiction:
Improvestructural simplicityVSAvoiddurability under extreme weather
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent implements a nested double-walled structure where an inner inflatable bladder is placed within an outer inflatable wall. The inner bladder contains the storage gas while the outer wall provides structural support and environmental protection. This nesting arrangement enables the structure to withstand extreme weather conditions while maintaining manufacturing simplicity.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The structure is divided into two independent functional segments: the inner bladder for gas storage and the outer wall for environmental resistance. This segmentation allows each component to be optimized for its specific function while working together to solve the contradiction between simplicity and durability.

Inventive Principle:
Principle #1Segmentation

2Strength

If the intermediate space is pressurized to meet wind and snow loading standards, then the structural strength is improved, but the energy consumption increases

Engineering Contradiction:
Improveresistance to wind and snow loadingVSAvoidblower energy consumption
Core Design Contradiction:
StrengthVSUse of energy by moving object

Solution Approach 1:

The system dynamically adjusts the pressurization parameter of the intermediate space based on environmental conditions. During extreme weather events, the blower increases pressure to meet wind and snow loading standards. During normal conditions, the pressure is reduced to minimize energy consumption, thus resolving the contradiction between strength and energy use.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The pressurization level of the intermediate space is made dynamic rather than static. The blower operation is controlled to provide variable pressure levels, increasing pressure only when environmental loads require enhanced structural strength, thereby optimizing the balance between strength and energy consumption.

Inventive Principle:
Principle #15Dynamics

3Quantity of substance

If multiple inflatable structures are interconnected to increase storage capacity, then the gas storage volume is improved, but the system complexity increases

Engineering Contradiction:
Improvegas storage volumeVSAvoidsystem interconnection complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

Each inflatable structure is designed as a universal module with standardized connection interfaces. Multiple identical modules can be interconnected through ductwork to achieve different storage capacities. This universality allows scalable expansion while keeping the increase in complexity manageable, as each module performs the same functions and connects in a standardized manner.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Reliability

If sensors and controls are added to manage pressure and environmental conditions, then the reliability is improved, but the device complexity increases

Engineering Contradiction:
Improvepressure management reliabilityVSAvoidcontrol system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Sensors are installed to monitor pressure and environmental conditions within the inflatable structure. This feedback information is fed to control systems that automatically adjust blower operation and valve positioning to maintain optimal conditions. The feedback mechanism improves reliability by enabling real-time monitoring and automatic correction of deviations.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The control system is designed to autonomously manage pressure and environmental conditions based on sensor inputs, reducing the need for manual intervention. The system self-regulates by automatically activating blowers, adjusting valves, and responding to environmental changes, thereby improving reliability while keeping operational complexity manageable through automation.

Inventive Principle:
Principle #25Self-service

AI summary

An inflatable structure for gas storage includes an inner bladder containing a gas for storage and an outer wall spaced from the inner bladder. An intermediate space between the bladder and the outer wall is pressurized with a gas (such as air) other than the storage gas so that the structure is protected from environmental conditions such as wind and snow loading. The bladder and outer wall may be flexible fabric membranes and may be provided with lightweight support frames. The structures may be combined in a network of like structures for large scale storage.
