Tripod Binding Sleeve Locking for Stable Folded Support Rods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tripod stands with rotating support rods face issues of deformation and instability during storage and transport due to shifted center of gravity and rotational freedom, requiring additional binding to maintain structure integrity.
Innovation Solution
A positioning structure for tripod stands featuring a main tube with upper, middle, and lower binding sleeves, each with joint tubes, and sliding slots with clamping columns and springs to securely hold and release the support rods, allowing quick transition between storage and unfolding positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the three support rods are rotated to the same plane for storage, then the volume is reduced and it is easier to carry, but the center of gravity shifts and the structure becomes unstable
Solution Approach 1:
The support system is divided into a main tube and three separate support rods that can be independently positioned. The binding sleeves segment the control of each rod, allowing individual locking at desired angles while maintaining overall structural integrity during storage
Solution Approach 2:
Binding sleeves act as intermediary components between the main tube and support rods. These sleeves provide a mechanical interface that allows the rods to be secured at specific positions, mediating between the need for compact storage and structural stability
2Stability of the object's composition
If additional binding ropes are used to fix the support rods, then the rotational freedom is restricted and stability is improved, but the device complexity increases
Solution Approach 1:
The binding function is merged into the structural components themselves. The binding sleeves are integrated with the main tube and support rods, combining the functions of connection, positioning, and locking into single components rather than requiring separate binding ropes
Solution Approach 2:
The clamping columns with spring mechanisms provide self-locking functionality. Once the support rods are positioned, the spring-loaded clamping columns automatically engage to secure them, eliminating the need for additional binding operations by the user
3Strength
If the clamping force is increased to prevent deformation, then the structural integrity is improved, but the ease of operation for releasing clamping state deteriorates
Solution Approach 1:
The clamping mechanism transitions from a static fixed-force system to a dynamic spring-loaded system. The spring allows the clamping force to be maintained during normal operation but can be easily overridden when release is needed, providing adaptive mechanical behavior
Solution Approach 2:
The spring is pre-loaded to provide automatic clamping force before any operation is needed. This preliminary action ensures the support rods are securely held during transport, while the pre-compressed spring can be quickly released by overcoming the initial spring force

Function Achieved in This Case
Enables convenient and stable deployment of tripod stands by maintaining structural integrity during storage and transport, reducing deformation and instability, and allowing easy rotation of support rods for efficient use.
Implementation Method 1
the middle binding sleeve includes a sliding slot provided with an upper clamping column, a lower clamping column and a spring, and the spring pushes the upper clamping column and the lower clamping column to respectively protrude from an upper side and a lower side of the middle binding sleeve

AI summary
A positioning structure for tripod stand for quickly releasing a clamping state, comprising a main tube, upper, middle and lower binding sleeves and three support rods. The binding sleeves are sleeved on the main tube to rotate freely. The middle binding sleeve comprises a sliding slot provided with an upper clamping column, a lower clamping column and a spring. The upper and lower clamping columns are connected with upper and lower pressing keys protruding out of the middle binding sleeve. When the pressing keys are pressed, the spring is compressed and the clamping columns no longer protrude from the upper and lower sides of the middle binding sleeve. The clamping state can be released and the support rods of the binding sleeves can be freely rotated by pressing the binding keys, so that the three support rods can be rotated to a storage position or an unfolding position.
