Rotating Structure for Tent Assembly with Nested Rotors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Car folding tents are large in volume when stored, despite having good rotation stability, due to their design.
Innovation Solution
A rotating structure comprising a shaft, first and second rotors, extensions, and axial limiters that share a common shaft to increase axial length and stability while reducing volume, with channels and plate-shaped members to facilitate rotation and volume reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the axial distance at rotating position is increased to improve rotation stability, then rotation stability is improved, but the stored volume becomes large
Solution Approach 1:
The patent implements nesting by placing the first extension inside the second rotor and the second extension inside the first rotor. This allows the extensions to be housed within the rotor structures themselves, eliminating the need for separate accommodating grooves and reducing the overall stored volume while maintaining the required axial distance for rotation stability.
Solution Approach 2:
The patent merges the functions of the extensions and rotors by integrating the extensions into the rotor structures. The first extension is rotatably connected to the first rotor, and the second extension is rotatably connected to the second rotor, allowing both extensions to share the same rotational space and reducing the overall volume occupied during storage.
2Stability of the object's composition
If four staggered rotating positions are used to achieve good rotation stability, then rotation stability is improved, but the stored volume remains large
Solution Approach 1:
The patent uses nesting to reduce volume by placing the first extension inside the second rotor and the second extension inside the first rotor. This allows four staggered rotating positions to be achieved within a compact configuration, as the extensions are housed within the rotor structures rather than occupying separate spaces.
3Ease of operation
If the tarpaulin and supporting framework are kept attached during folding, then operation convenience is improved, but the stored volume becomes large
Solution Approach 1:
The patent segments the tent structure into the tarpaulin and the supporting framework (including rotors and extensions). The supporting framework is designed to fold into a compact configuration where the first and second extensions are nested within the rotors, allowing the tarpaulin to be attached to this compact folded structure rather than a bulky unfolded one.

AI summary
A rotating structure and a tent assembly are provided. The rotating structure includes a shaft; a first rotor rotatably sleeved outside the shaft; a second rotor rotatably sleeved outside the shaft; a first extension connected with the first rotor, the first extension being rotatably sleeved outside the second rotor and the shaft; a second extension connected with the second rotor, the second extension being rotatably sleeved outside the first rotor and the shaft; a first axial limiter being in contact with the first extension away from the second extension; and a second axial limiter being in contact with the second extension away from the first extension. In view of a technical problem that a car folding tent is large in volume after being stored, the disclosure provides technical effect that it can make a volume of the stored tent small on a premise of ensuring good rotating stability.
