Solution Overview
Problem
Existing camera stands do not effectively manage the orientation and storage of camera arms to prevent interference and ensure stable imaging while allowing for compact storage.
Innovation Solution
A camera stand design featuring rotatable arms with fulcrums and a ball joint mechanism, along with magnetic locking devices, allows for adjustable camera orientation and storage positions to minimize interference and facilitate compact folding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the second arm is rotated toward the first arm for compact storage, then the storage compactness is improved, but the grip and device may interfere with the first arm
Solution Approach 1:
The patent implements dynamic positioning of the grip through a rotatable joint mechanism. The grip can be rotated to different positions (first position away from the first arm, second position near the first arm) depending on whether the stand is in use or storage mode. This dynamic adjustment allows the system to optimize for either operational functionality or storage compactness without permanent structural compromise.
Solution Approach 2:
The stand is divided into functionally independent segments: the first arm, second arm, grip, and device are connected through separate joints and fulcrums. This segmentation allows each component to be independently positioned and adjusted, enabling the grip to be rotated to appropriate positions that prevent interference with the first arm during storage while maintaining operational flexibility.
2Adaptability or versatility
If the grip is positioned to operate the device, then the device orientation is changeable, but the grip may interfere with the first arm when the second arm is rotated
Solution Approach 1:
The grip is designed with rotational freedom through a joint mechanism that allows it to move between different positions. When the second arm is in operational position, the grip can be positioned away from the first arm to ensure smooth operation. When storage is required, the grip can be rotated to a position that prevents interference, enabling the system to adapt between operational and storage states.
3Manufacturing precision
If the arms are designed to be rotatable for positioning flexibility, then the positioning precision is improved, but the structural complexity increases
Solution Approach 1:
The positioning system is segmented into discrete rotational joints at specific fulcrum points. Each joint provides controlled rotation for precise positioning, while the segmentation allows each joint to be independently designed and manufactured. This modular approach achieves high positioning precision without requiring an overly complex monolithic structure.
Solution Approach 2:
The patent employs spherical joint mechanisms that allow rotation in multiple directions while maintaining simple contact surfaces. The spherical geometry enables precise angular positioning through simple rotational movements around fulcrums, achieving high positioning precision with relatively simple spherical joint structures rather than complex multi-component mechanisms.

AI summary
A stand for a device includes a supporter that includes a first fulcrum; a first arm that is coupled to the supporter so as to be rotatable within a first rotational range around the first fulcrum, and that includes a second fulcrum at one end thereof; a second arm that includes a first end and a second end, the first end being coupled to the first arm so as to be rotatable within a second rotational range around the second fulcrum, and the first arm and the second arm being movable with respect to each other via the second fulcrum; a locking device that secures the first arm and the second arm to each other in a state in which the first arm and the second arm are at positions within their respective rotational ranges at which the first arm and the second arm are substantially parallel to each other.
