Camera Stand Arm Structure for Stable Positioning and Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera stands fail to effectively stabilize cameras during imaging, leading to shaking and instability, especially when trying to image subjects at different angles or positions.
Innovation Solution
A camera stand design featuring a supporter with rotatable first and second arms, a counterweight, and a locking mechanism that allows the arms to be stored compactly, using magnetic forces to secure the arms in place, ensuring stability and ease of movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the arms are designed to be rotatable for flexible positioning, then the adaptability is improved, but the stability deteriorates due to potential unintentional rotation
Solution Approach 1:
The counterweight mechanism enables the arm to automatically return to its initial position after being displaced. The gravitational force acting on the counterweight creates a restoring torque that self-corrects any unintentional rotation, eliminating the need for active control systems while maintaining both flexibility and stability
Solution Approach 2:
A counterweight is provided on the arm to balance the gravitational effect. The counterweight is positioned and dimensioned such that its gravitational torque opposes and balances the torque from the arm's weight, creating a neutral equilibrium that prevents unintentional rotation while allowing controlled movement
2Adaptability or versatility
If the arms are extended for imaging various subjects, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The stand is divided into modular components: a base, a first arm rotatably connected to the base, and a second arm rotatably connected to the first arm. This segmentation allows each component to be independently controlled and positioned, providing versatile imaging coverage while keeping the overall structure manageable and not overly complex
3Ease of operation
If the arms are made rotatable for positioning adjustments, then the ease of operation is improved, but the reliability deteriorates due to potential unintended movement
Solution Approach 1:
The counterweight creates a balancing gravitational torque that stabilizes the arm at any positioned angle. This passive stabilization mechanism reliably holds the arm in place without requiring active locking mechanisms, thereby maintaining both ease of operation and position holding reliability
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 design provides stable and flexible positioning for the camera, minimizing shaking during imaging and allowing for easy storage and transportation by maintaining the arms in a compact, parallel state, preventing unintentional rotation due to gravity or external forces.
Implementation Method 1
gravity acting on the second arm acts on the second arm so as to rotate the second arm toward the side of the first arm

AI summary
Provided is a stand for a device that is capable of storing, in a stable state, a plurality of arms that are rotatably coupled. The stand for a device includes a supporter including a first fulcrum, a first arm that is coupled to the supporter so as to be rotatable around the first fulcrum and that includes a second fulcrum on one end, and a second arm that includes a first end and a device-side second end, the first end being coupled to the first arm so as to be rotatable around the second fulcrum. In a case where the first arm and the second arm are positioned at stored positions, the second fulcrum is positioned below the first fulcrum and, also, the second arm is tilted with respect to the vertical direction toward the first arm side.
