Tripod Bracket Key Release for One-Press Leg Unfolding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional auxiliary photographing devices require users to use one hand to press a key and the other hand to remove supporting legs, leading to an inconvenient unfolding process.
Innovation Solution
A bracket with a key that moves along the axial direction of the main rod, disengaging clamping members when pressed, and an elastic portion that elastically presses against the legs to automatically unfold them upon key activation, eliminating the need for manual leg removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a key with clamping members is used to lock the supporting legs, then the supporting legs can be securely locked when gathered up, but the unfolding process becomes inconvenient requiring multiple hands to operate
Solution Approach 1:
The elastic portion is pre-loaded during the gathering-up process, storing elastic potential energy that is ready to automatically unfold the supporting legs when the clamping members are released, eliminating the need for manual unfolding operation
Solution Approach 2:
The system uses the user's own gathering-up action to automatically charge the elastic portion, which then self-activates to unfold the supporting legs when unlocked, making the system serve itself without requiring additional manual effort for unfolding
2Device complexity
If the key is fixed on the main rod, then the structure is simple, but the clamping members cannot be disengaged to allow leg unfolding
Solution Approach 1:
The key is changed from a fixed structure to a movable structure that can slide along the main rod axially, allowing the clamping members to be disengaged from the legs when the key is pressed, enabling the legs to be unfolded
3Ease of operation
If manual force is applied to remove each supporting leg, then the legs can be unfolded, but the operation becomes complex and time-consuming
Solution Approach 1:
The elastic portion is pre-loaded during the gathering-up process, storing elastic potential energy that is ready to automatically unfold the supporting legs when the clamping members are released, eliminating the need for manual unfolding operation
Solution Approach 2:
The system transforms the continuous manual effort required for leg removal into a single periodic action of pressing the key, which triggers the automatic unfolding mechanism
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
The solution allows for convenient and efficient unfolding of supporting legs by pressing the key alone, reducing the complexity of operation and enhancing user experience.
Implementation Method 1
an elastic portion arranged on the main rod and elastically pressed against a side of each of the plurality of legs that faces the main rod when the plurality of legs is gathered up together

AI summary
A bracket and an auxiliary photographing device thereof are provided. The bracket includes a main rod, a key installed in a bottom of the main rod, an elastic portion installed on the main rod, and a plurality of legs rotatably connected to the main rod; a first clamping member formed at a side of each leg that faces the main rod, a second clamping member formed at a portion of the key facing each leg and engaged with the first clamping member, the elastic portion elastically pressed against a side of each leg that faces the main rod when the plurality of legs is gathered up together. The key is pressed to drive the second clamping member to move, to cause the first clamping member being detachable from the second clamping member, so that the elastic portion is no longer constrained by the first and second clamping members.
