Solution Overview
Problem
Existing hard shell rooftop tents face issues of limited livable space and fabric crumpling during storage, with box-shaped designs compromising weather protection and clamshell designs restricting height.
Innovation Solution
A rooftop tent assembly with a rigid base and hinged panels that pivot to an open configuration, utilizing gas springs for easy deployment and closure, and a frame assembly with arched supports to maximize livable space and minimize fabric crumpling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a box-shaped hard shell design is used, then weather protection is improved, but fabric crumpling and storage issues worsen
Solution Approach 1:
The hard shell is divided into multiple hinged panels (first hard shell panel, second hard shell panel, third hard shell panel) that can pivot independently. This segmentation allows each panel to be positioned optimally for weather protection while enabling the fabric enclosure to be properly stored in the hard shell without crumpling, as the panels can be adjusted to accommodate the fabric storage process.
2Object-generated harmful factors
If a clamshell design is used, then fabric storage is improved, but livable space worsens
Solution Approach 1:
The patent extends the clamshell design by adding a third hard shell panel that pivots from the second panel, creating a multi-dimensional opening structure. This additional dimension allows the hard shell to maintain a compact closed form for easy fabric storage while providing sufficient internal volume and headroom for livable space when opened, as the multiple panels create a more expansive interior space compared to a traditional two-panel clamshell design.
3Productivity
If a box-shaped design is used, then setup speed is improved, but closing time worsens
Solution Approach 1:
The hard shell panels are equipped with hinges that enable dynamic pivoting motion, allowing the structure to transition smoothly between closed and open states. The gas springs provide dynamic assistance during the pivoting action, making both setup and closing operations quick and easy. The hinged connection points are designed to guide the panels through their motion paths, reducing the time required for closing compared to traditional box-shaped designs that require manual manipulation of each panel.
4Ease of operation
If a clamshell design is used, then closing effort is improved, but height restriction worsens
Solution Approach 1:
The hard shell is segmented into multiple panels of different sizes and positions. The first hard shell panel forms the front wall, the second panel forms the rear wall, and the third panel forms the roof. This segmentation allows each panel to pivot independently, maintaining ease of operation while the third panel's positioning creates sufficient internal height for livable space, overcoming the height restriction problem of traditional clamshell designs.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The assembly provides enhanced weather protection and increased livable space while reducing the time and effort required for setup and teardown, minimizing fabric crumpling and storage issues.
Implementation Method 1
Gas springs may be provided to assist the hard shell in pivoting upward to the open configuration
Implementation Method 2
A hinge may be provided to connect one edge of the hard shell to the base, so the hard shell pivots upward

AI summary
A shelter assembly a flat base having a first rim section, a second rim section, and opposite side rim sections extending between the first and second rim sections. The assembly includes a rigid lower panel having a lower edge, an upper edge, and opposite side edges. The lower edge is pivotably connected to the first rim section for movement between a closed orientation and an open orientation. The shelter assembly includes a rigid upper panel having a first end, a second end, and opposite sides. The first end is pivotably connected to the upper edge for pivoting movement relative to the lower panel between a closed configuration and an open configuration. Each side panel extends between one side edge of the lower panel, one corresponding side of the upper panel, and one corresponding side rim section and the one side of the upper panel.
