Hinged Rooftop Tent Cover for Waterproofing Without Drag
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicular rooftop tents obstruct the driver's field of vision, increase air resistance, and have poor waterproofing and aesthetics, making them inconvenient for use while driving.
Innovation Solution
A rooftop tent design featuring a first and second plate-shaped cover part connected by a hinge, with a waterproof fabric system that includes a fastening rod, adjustable belt, and tightening module, allowing for easy attachment and detachment, and providing a secure, aerodynamic, and visually appealing solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a waterproof cover made of tarpaulin is used to cover the rooftop tent, then waterproofing is improved, but air resistance increases and driver's field of vision is obstructed
Solution Approach 1:
The cover is divided into a hard cover portion and a soft cover portion. The hard cover provides structural support and aerodynamics, while the soft cover provides waterproofing only where needed (at the rear end), eliminating the need for a complete tarpaulin cover that would obstruct vision and increase drag.
Solution Approach 2:
Waterproofing is applied locally rather than uniformly across the entire cover. The soft waterproof cover portion is positioned only at the rear end where waterproofing is most critical, while the front and sides use the hard cover that maintains aerodynamics and does not obstruct the driver's view.
2Reliability
If a complete soft waterproof cover is used, then waterproofing is improved, but appearance and aerodynamics deteriorate
Solution Approach 1:
The cover system is segmented into hard and soft portions, combining the aerodynamic benefits of rigid structures with the waterproofing advantages of flexible materials in the appropriate locations.
Solution Approach 2:
The soft waterproof cover is applied locally at the rear end where it is most effective, rather than covering the entire rooftop tent structure, thus preserving aerodynamics and appearance in the front and side regions.
3Reliability
If the waterproof fabric is permanently attached to the cover, then waterproofing reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The waterproof fabric attachment system is made dynamic and adjustable through the tightening module with belts and fastening rods. Users can tighten or loosen the fabric as needed, and easily detach it when not required, transforming a static permanent attachment into a dynamic adjustable system.
Solution Approach 2:
The attachment system allows changes in tension and positioning parameters of the waterproof fabric. The tightening module enables adjustment of the fabric's tightness and position, while the detachable design allows complete removal when needed.

AI summary
A rooftop tent according to one embodiment of the present invention comprises: a first cover part including a first plate-shaped member provided in a plate shape; a second cover part including a second plate-shaped member provided in a plate shape; a hinge connection part rotatably connecting the first cover part and the second cover part; a tent part coupled to the first cover part and the second cover part; and a waterproof part having one end fastened to the first cover part. One of the first cover part or the second cover part can be fixedly installed on the roof of a vehicle. The rooftop tent may have a folding mode in which the first cover part and the second cover part are arranged side by side, and the tent part is accommodated in the space between the first cover part and the second cover part, and an unfolding mode in which the tent part unfolds as one of the first cover part or the second cover part rotates about the hinge connection part with respect to the other.
