Innovation Solution
A foldable tent frame design featuring a base, foldable tent frame rods, and a middle support rod with a control mechanism using a pull rope, rope disk, and drive device for simplified sliding and folding/unfolding, allowing quick deployment and stowage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple joints and fixing structures are used to enable folding and unfolding, then the tent frame can be folded for storage and carrying, but the operation becomes troublesome and time-consuming
Solution Approach 1:
The patent merges multiple joints and fixing structures into a single integrated joint structure. The first and second rods are connected through a unified joint mechanism that combines the folding and fixing functions, eliminating the need for separate joints and fixing structures. This reduces the number of operational steps while maintaining the folding capability.
Solution Approach 2:
The joint structure is designed to perform multiple functions simultaneously: it enables folding, provides fixing, and allows easy deployment. The universal joint mechanism can transition between locked and unlocked states, serving both as a connection point and a fixing mechanism, thereby simplifying operation.
2Adaptability or versatility
If multiple joints and fixing structures are used to enable folding and unfolding, then the tent frame can be folded for storage and carrying, but the operation consumes a lot of time
Solution Approach 1:
By combining multiple joints and fixing structures into a single integrated joint, the patent reduces the number of sequential operations required for folding and unfolding. The unified structure allows simultaneous action on multiple rods, significantly reducing the time needed for deployment and storage.
Solution Approach 2:
The joint structure is pre-configured with spring members and limiting blocks that automatically engage and disengage during folding and unfolding operations. This preliminary arrangement of components enables rapid transitions without requiring manual adjustment of multiple separate fixing mechanisms.
3Ease of operation
If a simple configuration is used for the tent frame, then the operation is convenient, but the folding and unfolding control is less precise
Solution Approach 1:
The patent introduces spring members and limiting blocks as intermediary elements within the joint structure. These components act as mediators that provide precise control over the folding and unfolding movements while maintaining operational simplicity. The spring members control the engagement force, and the limiting blocks define the exact folding positions.

AI summary
A foldable tent frame includes a base, a foldable tent frame rod mounted on the base, and a middle support rod for controlling the folding and unfolding of the tent frame rod; the top end of the middle support rod is pivotably connected to a fixed position on the tent frame rod, and the bottom end is slidably and pivotably connected to the base; when the middle support rod is erected via the bottom end sliding on the base, the tent frame rod is unfolded accordingly; when the middle support rod collapses via the bottom end sliding on the base, the tent frame rod is folded accordingly; the tent can be quickly folded or unfolded by controlling the sliding of the bottom end of the middle support rod on the base, and the foldable tent frame is structurally simple and easy to operate.
