Inflatable Beam Awning Structure Without Ground Poles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle awnings with complex frames are difficult to set up, susceptible to corrosion, occupy space, and may collapse if not properly anchored, necessitating a need for a self-standing, easy-to-set-up, and durable solution.
Innovation Solution
A frame assembly using inflatable beam members made of thermoplastic polyurethane (TPU) material, with a rail system and connector assemblies, allowing for a standalone awning structure that mounts directly to a vehicle without ground poles, featuring a single inflation point for enhanced structural integrity and ease of setup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional frames made of aluminum or steel are used, then structural strength is improved, but susceptibility to corrosion increases
Solution Approach 1:
The patent changes the material parameter from traditional metal (aluminum or steel) to inflatable beam material, fundamentally altering the structural approach while maintaining strength through air pressure rather than material density
Solution Approach 2:
The patent applies pneumatic principles by using inflatable beams filled with air to provide structural support, replacing solid metal frames with air-filled chambers that expand to create rigid support structures resistant to corrosion
2Stability of the object's composition
If supporting poles are added to the frame, then stability is improved, but device complexity increases
Solution Approach 1:
The patent merges the supporting pole function into the inflatable beam structure itself, where the inflatable beams perform both the primary frame and supporting pole functions, eliminating the need for separate supporting poles
Solution Approach 2:
The inflatable beams serve multiple functions simultaneously: they act as the main frame structure, provide supporting pole functionality, and offer anchorage points, making the system more universal and less complex
3Strength
If complex frames with multiple components are used, then structural support is improved, but ease of setup deteriorates
Solution Approach 1:
The patent segments the frame into modular inflatable beam components that can be independently inflated and assembled, allowing for easier setup while maintaining structural support through the modular nature of the segments
Solution Approach 2:
The patent introduces dynamic elements through inflatable beams that can be quickly inflated to transform from a compact state to a fully supported structure, enabling rapid setup without complex assembly of rigid components

AI summary
An awning assembly comprises a frame assembly supporting an awning canopy. The frame assembly comprises frame members made of inflatable beams. The rear section of the frame assembly includes horizontal and vertical frame members, and a rail assembly connects to both a support structure and the frame assembly. The rail assembly comprises keder rails, and the awning assembly further comprises connector assemblies. Connector assemblies, vertically positioned over the rail assembly, supports the vertical frame members. The rail assembly supports the horizontal frame members. The rail assembly is affixed to the support structure via a bracket, while connector assemblies secured to the rail assembly with nuts and slots. Utilizing T-shaped slots and nuts, the assembly ensures compatibility. The inflatable beam members made of thermoplastic polyurethane (TPU) provide durability. Additionally, the frame assembly forms a roof-shaped configuration, suitable for various applications.
