Pocket Tripod Folding Structure With Nested Legs and Feet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tripods are inconvenient to carry due to a large size when folded, caused by a significant interval between the supporting legs and the middle shaft tube.
Innovation Solution
A portable tripod design that includes a connecting assembly, supporting feet embedded in the legs, and a middle shaft tube, allowing the legs and feet to fold inward to form a compact hollow cylinder that matches the middle shaft tube, maximizing space utilization and reducing size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the tripod is folded for easy carrying, then the portability is improved, but the size remains large due to the interval between supporting legs and middle shaft tube
Solution Approach 1:
The supporting legs are designed with embedded supporting feet that can be folded inward to form a compact hollow cylinder structure. The middle shaft tube is embedded into the connecting assembly, and the hollow cylinder formed by the supporting legs and feet compactly matches the middle shaft tube, creating a nested configuration that maximizes space utilization and minimizes the folded volume.
Solution Approach 2:
The supporting leg employs a three-dimensional hollow ring structure with arc-shaped walls that allow the leg and embedded supporting feet to fold inward along a curved path. This dimensional approach enables the formation of a compact hollow cylinder that efficiently utilizes the radial and axial spaces, allowing the structure to collapse into a much smaller volume while maintaining structural integrity.
2Volume of moving object
If the supporting feet are embedded into the supporting legs to reduce size, then the compactness is improved, but the structural strength may be compromised
Solution Approach 1:
The supporting leg is designed with an arc-shaped upper wall and lower wall that encircle to form an annular tube body, creating a curved, hollow ring structure. This spherical/curved geometry provides inherent structural strength while allowing the supporting feet to be embedded within the hollow space. The curved walls distribute stresses more effectively than flat structures, maintaining strength despite the compact nested configuration.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The portable tripod is compact and small in size when stored, making it highly portable while maintaining structural strength and stability through the embedded supporting feet and the telescopic middle shaft tube.
Implementation Method 1
a head end of the supporting leg is rotatably connected with the connecting assembly
Implementation Method 2
At least one supporting foot is embedded into each of the first to third supporting legs
Implementation Method 3
The locking threaded hole is in threaded connection with the locking knob
