Monitor Mount Joint Assembly With Switchable Angle Stop Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitor mounts face challenges in balancing the appearance and operational convenience, as external screws or built-in parts for rotation limiting can affect the aesthetic integrity and are cumbersome to operate.
Innovation Solution
A joint assembly for monitor mounts featuring a first joint, a second joint, a limiting assembly with a limiting component, and a rotating assembly on the outer periphery, allowing the limiting component to switch between positions to restrict or release the second joint's rotation, enhancing appearance and convenience by avoiding external screws and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If external screws are used for rotation limiting, then the rotation range can be controlled, but the appearance and overall integrity of the mount are affected
Solution Approach 1:
The limiting component is extracted from the traditional external screw form and integrated into the joint assembly's internal structure. The limiting component can be moved between a first position (extending outward to limit rotation) and a second position (retracted to release the limit), allowing rotation control without permanent external screws that compromise appearance.
Solution Approach 2:
The limiting component is made dynamically adjustable rather than fixed. It can be positioned in different states (limited or released) based on user needs, enabling the mount to switch between rotation-limited and rotation-free modes without compromising appearance in either state.
2Shape
If built-in parts are used for rotation limiting, then the appearance is maintained, but the operation becomes cumbersome requiring disassembly
Solution Approach 1:
The rotating assembly serves itself by directly driving the limiting component through its rotation. When the rotating assembly rotates, it automatically moves the limiting component between the first and second positions through the interlinking mechanism, eliminating the need for separate disassembly and assembly operations.
Solution Approach 2:
The rotation control function and the limiting component adjustment function are merged into a single operation. Rotating the rotating assembly simultaneously achieves both the rotation control and the limiting component positioning, simplifying the user operation to a single intuitive action.
3Reliability
If the limiting component is always extended to limit rotation, then the mount cannot hit the wall, but the user cannot achieve 360-degree rotation when needed
Solution Approach 1:
The limiting component transitions from a static fixed-position design to a dynamic adjustable design. Users can switch between the first position (collision prevention mode) and the second position (360-degree rotation mode) based on their specific needs, making the system adaptable to different usage scenarios.
Solution Approach 2:
The rotation angle parameter of the joint assembly can be changed between two states: limited rotation (when limiting component is in first position) and 360-degree rotation (when limiting component is in second position). This parameter changeability provides both safety and flexibility.

AI summary
The present disclosure describes devices and systems of a joint assembly for a monitor mount and the monitor mount. The joint assembly includes a first joint; a second joint rotationally connected with the first joint; a limiting assembly disposed on the first joint and comprising a limiting component, wherein: when the limiting component is at a first position, the limiting component limits the second joint to rotate within a limit of a preset angle range relative to the first joint, and when the limiting component is at a second position, the limiting component releases the second joint from the limit; and a rotating assembly rotatably disposed on an outer periphery of the first joint, wherein: the rotating assembly is engaged with the limiting component, and a rotation of the rotating assembly drives the limiting component to switch between the first position and the second position.
