Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deployable structures with rigidizing elements require complex connection schemes and multiple components, making them difficult and time-consuming to construct, and are prone to component loss due to bulkiness.
Innovation Solution
A deployable panel with inflatable rigidizing members that extend along multiple sides of reconfigurable elements, allowing for structural support without the need for intricate connections, using a system of first, second, and third inflatable rigidizing members arranged between and across elements, which can be inflated to provide support and transition between stowed and deployed configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple rigidizing elements and connectors are used to provide multi-axis support, then structural support capability is improved, but device complexity and ease of operation deteriorate due to complicated connection schemes
Solution Approach 1:
The patent merges multiple rigidizing elements into a single integrated inflatable structure. Instead of using separate aluminum tubes or carbon-fiber rods that require complex nodes and connectors, the invention uses a unified inflatable member that can extend along multiple sides of the panel, providing multi-axis structural support through a single component that eliminates the need for complicated connection schemes
Solution Approach 2:
The patent applies pneumatic principles by using inflatable members filled with gas or liquid to provide structural rigidity. The inflatable rigidizing member can be inflated to assume a rigid configuration that supports the panel in multiple directions, and deflated for easy storage and deployment, replacing traditional rigid mechanical components with pneumatic actuators
2Strength
If multiple rigidizing elements and connectors are used to provide multi-axis support, then structural support capability is improved, but ease of operation worsens due to difficulty in construction
Solution Approach 1:
The patent combines multiple rigidizing functions into a single inflatable component that can be deployed as one unit. This integrated approach eliminates the need for assembling multiple separate elements and connectors, making construction simpler and more straightforward while maintaining the ability to provide structural support in multiple directions
Solution Approach 2:
The patent introduces dynamic characteristics by using an inflatable member that can transition between a deflated state for easy storage and transport, and an inflated state for providing structural support. This dynamic capability allows the structure to be easily deployed and stored without the complexity of assembling and disassembling multiple rigid components
3Strength
If traditional rigidizing elements are used, then structural support is provided, but loss of time increases due to time-consuming construction
Solution Approach 1:
The patent applies preliminary action by pre-forming the rigidizing structure as an inflatable member that is ready for deployment. The inflatable member is manufactured in advance with the appropriate geometry and can be quickly inflated to provide structural support, eliminating the time required for on-site assembly of multiple rigidizing elements and connectors
Solution Approach 2:
The patent merges multiple rigidizing elements into a single integrated inflatable component that provides multi-axis structural support. This consolidation reduces the number of assembly steps and components required, significantly reducing construction time while maintaining the structural support capabilities needed for panel stability

AI summary
A deployable structure includes a reconfigurable member formed from a plurality of elements defining a first end, a second end that is opposite the first end, a first side extending between the first end and the second end, and a second side, opposite the first side, extending between the first end and the second end. A first inflatable rigidizing member extends along the first side across each of the plurality of elements and a second inflatable rigidizing member extends along the second side across each of the plurality of elements.
