Tent Cloth Connecting Structure for Fold-Up Tents
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fold-up tents face issues where the tent cloth deforms and lengthens during unfolding, leading to damage and inconvenience, and when the cloth is overlong, it becomes loose and not flat, affecting appearance and stability.
Innovation Solution
A connecting structure for the tent cloth and leg pole featuring a sliding element and lock structure that allows the leg pole to change length, ensuring the tent cloth remains flat and tensioned during unfolding and folding, with a sliding element connected to the tent cloth and a lock mechanism that adjusts the leg pole's length for easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the tent cloth is just coupled to the tent rack, then the tent rack is flat when unfolded, but the tent cloth deforms and lengthens during unfolding, making it easy to damage and inconvenient to unfold
Solution Approach 1:
The patent applies a sliding mechanism that allows the tent cloth connection point to move dynamically along the leg pole during unfolding. The sliding element can slide along the first pole, enabling the connection position to adjust automatically as the tent unfolds, preventing deformation and damage to the tent cloth while maintaining the flatness of the tent rack structure.
2Ease of operation
If the tent cloth is overlong, then it is convenient to fold and unfold and the tent cloth doesn't deform, but the tent cloth is loose and not flat when the tent is set up, making the appearance not attractive and low strength and stability
Solution Approach 1:
The sliding mechanism enables dynamic adjustment of the tent cloth connection position along the leg pole. During setup, the sliding element can be positioned to tension the tent cloth properly; during folding and unfolding, the same mechanism allows the connection point to move, maintaining convenience while preventing the tent cloth from being loose or non-flat.
Solution Approach 2:
The patent changes the position parameter of the connection point between the tent cloth and leg pole. By allowing the sliding element to move to different positions on the first pole, the effective length and tension of the tent cloth can be adjusted, achieving both stability during setup and ease of operation during folding and unfolding.
3Shape
If the tent cloth is tensioned during unfolding, then the tent cloth maintains its shape, but the constant deforming and tensioning makes it easy to damage and inconvenient to unfold
Solution Approach 1:
The sliding mechanism provides dynamic tension adjustment during unfolding. Instead of constant tensioning, the sliding element can move along the first pole to accommodate the unfolding motion, maintaining the tent cloth shape only when needed while reducing tensioning during the unfolding process itself, thereby improving ease of operation.

AI summary
A tent cloth connecting structure for a fold-up tent includes a leg pole including first and second poles that slide relative to one another; and a tent cloth having a lower portion disposed with a first connecting unit and a first flexible element, a second connecting unit disposed above the first connecting unit, and a sliding element attached to the tent cloth and slidably connected to the first pole. The sliding element and a lower portion of the first pole are retained by a locking structure. The first pole is disposed with a limit structure limiting passage of the second connecting unit and having a protruding portion. The second connecting unit includes a connecting base slidably connected to the first pole and located below the protruding portion which limits the passage of the connecting base, and a second flexible element that connects the connecting base and the tent cloth.
