Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rooftop tents face issues with stability, ease of installation and disassembly, crude driving mechanisms, and inadequate space for family camping, along with problems like condensation and deformation.
Innovation Solution
A vehicle rooftop tent with a link structure, hard-shell cover, and extension plate that unfolds and folds with one-touch operations, featuring a lightweight honeycomb structure, shock absorbers, and high-strength wires to ensure stability and space, along with a heat-insulating layer to prevent condensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a rotating plate or extension plate is unfolded to expand the tent, then the space for family camping is increased, but the stability of the tent deteriorates because the tent is not located in the center of the vehicle
Solution Approach 1:
The tent system is divided into a fixed lower case mounted on the vehicle roof and a separate deployable upper case with extension plates. The lower case remains stationary and centered on the vehicle, maintaining stability, while the upper case can be expanded outward with extension plates to increase living space without compromising the central positioning and structural stability of the main tent body.
2Ease of operation
If a crude driving device is used to unfold the extension plate, then the ease of operation is improved, but the device complexity increases and reliability decreases
Solution Approach 1:
The extension plate unfolding mechanism utilizes the existing motion of the upper case deployment to automatically drive the extension plates outward. As the upper case is raised and positioned, the extension plates are self-driven to extend laterally through the inherent mechanical interaction between the upper case movement and the extension plate connection structure, eliminating the need for separate crude driving devices while maintaining ease of operation.
3Volume of moving object
If the upper case is deployed to expand the tent, then the space for camping is increased, but the time required for installation and disassembly increases
Solution Approach 1:
The deployment of the upper case and the unfolding of the extension plates are merged into a single integrated operation. When the upper case is deployed from the lower case, this action simultaneously triggers and drives the extension plates to unfold. This combined motion allows the tent to expand both vertically and horizontally in one coordinated movement, significantly reducing the time required for installation and disassembly while maximizing camping space.
4Strength
If a hard-shell cover is used for the upper case, then the strength and resistance to deformation are improved, but the weight of the tent increases
Solution Approach 1:
The upper case employs composite material construction, combining rigid structural elements for strength with lighterweight materials where possible. The hard-shell cover provides necessary structural integrity and resistance to deformation, while the overall design optimizes the material composition to minimize weight. This composite approach allows the upper case to maintain sufficient strength for protecting the expanded tent space while keeping the additional weight manageable for vehicle mounting and deployment.

AI summary
The present disclosure provides a vehicle rooftop tent including a tent, an upper case, a link structure, a lower case, and an extension plate. The tent has an upper end connected to the upper case and a lower end connected to a lower case and the extension plate. The upper case includes a hard-shell cover and a straight section fastened by an extrusion structure rivet. The link structure is disposed at each corner of the lower case. The extension plate is unfolded and folded in conjunction with the opening and closing of the tent. The lower case has a honeycomb structure. The extension plate is unfolded and extended to both sides of the lower case to expand a floor area when the tent is open, and is folded to be stored in an upper portion of the lower case to reduce the floor area when the tent is closed.
