Photographic Stand Locking Assembly for Quick Lock-Unlock Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional locking assemblies for photographic equipment stands are complex and time-consuming to operate, making it inefficient to switch between freely rotatable and locked states, which can result in missed shooting opportunities.
Innovation Solution
A locking assembly with a support rod, guiding member, locking pin, spring member, and driving member, where the locking pin moves between fixed positions to lock or unlock the stand, allowing for quick and efficient switching between states using a universal ball and abutting surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional screw fastening locking assembly is used, then the stand can be locked securely, but the operation becomes complex and time-consuming
Solution Approach 1:
The patent replaces the traditional screw fastening mechanical system with a button-driven locking mechanism. The button (70) connects to a locking block (605) that moves along a groove to engage or disengage the locking pin (40) with the guiding member (30), eliminating the need for screw threading and rotation operations.
Solution Approach 2:
The patent extracts the core locking function from the complex screw fastening system, isolating it into a dedicated locking assembly with a button-driven mechanism. The locking pin (40) and guiding member (30) interaction is separated from the connecting member structure, allowing independent operation of the locking function.
2Reliability
If traditional screw fastening locking assembly is used, then the stand can be locked securely, but the operation becomes time-consuming
Solution Approach 1:
The patent replaces the time-consuming screw rotation and threading operations with a rapid button-press mechanism. The button (70) directly translates linear motion to the locking block (605), which quickly engages or disengages the locking pin (40) from the guiding member (30) in a single motion.
Solution Approach 2:
The locking pin (40) is pre-positioned within the guiding member (30) structure, and the button (70) is pre-configured to directly control the locking block (605) movement. This preliminary arrangement eliminates the need for complex alignment and multi-step operations during actual locking or unlocking.
3Adaptability or versatility
If the locking assembly is frequently switched between locked and unlocked states, then the stand remains flexible, but the complexity and time consumption accumulate
Solution Approach 1:
The patent extracts the locking function into a separate, dedicated locking assembly that can be independently operated. The locking pin (40), guiding member (30), locking block (605), and button (70) form a self-contained mechanism that can be frequently engaged and disengaged without affecting the overall stand structure.
Solution Approach 2:
The locking assembly is designed with dynamic components that allow frequent state changes. The button (70) can be pressed to move the locking block (605) along the groove, enabling the locking pin (40) to quickly transition between engaged and disengaged positions with the guiding member (30).
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient and high-efficiency switching between locked and unlocked states, reducing the complexity and time required for operation, thus minimizing the risk of missing critical shooting moments.
Implementation Method 1
a spring member located between the pedestal and the guiding member
Implementation Method 2
One end of the support rod and the connecting member are rotatably connected with each other by a universal ball

AI summary
A stand for photographic equipment includes a connecting member, a pedestal, and a locking assembly connected therebetween. The locking assembly includes a support rod, a guiding member mounted around the support rod, a locking pin fixed on the support rod and engaged with the guiding member, a spring member located between the pedestal and the guiding member, and a driving member pivotally connected to the support rod. One end of the support rod and the connecting member are rotatably connected with each other by a universal ball. The locking assembly is configured to make the locking pin move along the guiding member to a first fixed position or a second fixed position by pressing the driving member. In the first fixed position, a top end of the guiding member abuts against and locks the connecting member. In the second fixed position, the guiding member releases the connecting member.
