Tent Joint Structure with Limiting Groove for Single-Handed Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tent joint structures require multiple experienced individuals to pitch or unpitch a tent due to complex processes, making it difficult for individuals to fold or unfold tent rods synchronously.
Innovation Solution
A joint structure comprising a first assembly with an annular wall and limiting groove, a second assembly with a limiting protrusion, and a controlling button that allows for easy folding and unfolding by enabling single-handed operation, simplifying the process of pitching or unpitching a tent independently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional securing pins are used to connect joints, then the connection is reliable, but the operation process becomes complicated and requires multiple experienced people
Solution Approach 1:
The invention extracts the securing function from the traditional pin mechanism and integrates it into the joint structure itself. The limiting protrusion on the rod is automatically constrained by the limiting groove in the joint body, eliminating the need for separate securing pins and their complex manipulation procedures.
Solution Approach 2:
The joint structure performs self-securing through the limiting protrusion and limiting groove mechanism. When the rod is inserted into the joint, the limiting protrusion automatically engages with the limiting groove, providing self-alignment and self-securing without requiring user intervention for pin insertion or rotation.
2Stability of the object's composition
If multiple securing pins are used to ensure stable connection, then the connection stability is improved, but the device complexity increases
Solution Approach 1:
The invention merges the securing function, positioning function, and connection function into a single integrated joint structure. The limiting groove simultaneously provides securing, positioning, and guiding functions, eliminating the need for multiple separate components and reducing overall structural complexity.
Solution Approach 2:
The limiting groove structure serves multiple functions: it secures the rod, positions it radially, guides its insertion, and prevents over-rotation. This multi-functional design replaces what would traditionally require multiple separate components, simplifying the overall joint structure while maintaining stability.
3Strength
If traditional pin mechanisms are used for joint connection, then the structural strength is maintained, but the ease of manufacture decreases
Solution Approach 1:
The invention segments the joint into distinct functional elements: the joint body with limiting groove, and the rod with limiting protrusion. This segmentation allows each component to be manufactured independently with simpler processes, then assembled together, reducing overall manufacturing complexity while maintaining joint strength.

AI summary
A joint structure has a first main body (11), a positioning pin (13), a second main body (21), and a controlling button (30). The first main body (11) forms with an annular wall (112) and a limiting groove (113), and the annular wall (112) forms an engaging passage (116). The positioning pin (13) is mounted in the first main body (11). The second main body (21) has a limiting protrusion (212) and is rotatably mounted on the first main body (11). The controlling button (30) is mounted on the second main body (21) and forms a positioning groove (31) and an engaging block (32) corresponding to the engaging passage (116). The positioning pin (13) can abut the positioning groove (31). With the cooperation of the positioning groove (31) and the positioning pin (13), the joint structure can be folded or unfolded easily.
