Inflatable Vehicle Awning With Adjustable Tubular Frame Length
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle awnings with inflatable frames are not variable in size and cannot be adapted to vehicles of different heights, limiting their versatility and adaptability.
Innovation Solution
The awning includes means for changing the length of its tubular components, such as a third tubular portion with connectable ends and modular design, allowing it to be adjusted to fit various vehicle heights and provide flexible coverage, with optional support posts for independent standing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the awning uses a fixed-length tubular frame, then the construction is simplified and easier to manufacture, but the awning cannot be adapted to vehicles of different heights
Solution Approach 1:
The tubular frame is divided into multiple detachable sections (first tubular region, second tubular region, third tubular portion) that can be connected or separated. This segmentation allows the frame length to be adjusted by connecting or disconnecting sections, enabling adaptation to different vehicle heights while maintaining relatively simple construction within each section.
Solution Approach 2:
The frame transitions from a fixed static structure to a dynamic adjustable structure. The connecting means allow the frame length to be changed based on requirements, making the awning adaptable to different vehicle heights and configurations while maintaining operational simplicity through straightforward connection and disconnection operations.
2Adaptability or versatility
If the awning includes means for changing tube length, then adaptability to different vehicles is improved, but the device complexity increases
Solution Approach 1:
The frame is segmented into standard-length sections with identical connecting interfaces. This standardization ensures that assembly and disassembly operations remain simple and intuitive, while the combination of sections provides versatile length adjustment capabilities for different vehicle configurations.
Solution Approach 2:
The connecting means serve multiple functions: they join tubular sections together, allow for length adjustment, and enable rapid assembly and disassembly. This multi-functionality maintains ease of operation while achieving versatile adaptability across different vehicle types and configurations.
3Area of stationary object
If the awning uses detachable tubular sections, then the covered base area can be varied, but the number of components increases
Solution Approach 1:
The frame is divided into a minimal number of essential sections (first tubular region, second tubular region, third tubular portion) that provide sufficient coverage area when connected. This segmentation allows area adjustment by connecting or disconnecting sections while keeping the total number of components to a practical minimum for effective base area coverage.
Solution Approach 2:
Multiple tubular sections are merged into a unified frame structure when connected, creating continuous support elements that efficiently cover the base area. The merging of sections provides large area coverage when needed, while the ability to separate them reduces component quantity to only what is necessary for the required coverage.
