Monitor Arm Connector With Rotating Lock for Tool-Free Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional monitor mounting processes require users to hold the monitor with one hand and operate a screwdriver with the other, making the process difficult and unsafe.
Innovation Solution
A connecting device with an installing seat, a tab module, and a rotating plate is designed to be mounted between a monitor and a supporting arm device. The rotating plate allows the tab module to be easily inserted or removed from the slotting space, enabling quick mounting and dismounting of the monitor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to connect the adapter plate to the bracket, then the connection is secure and reliable, but the mounting process becomes difficult and requires two hands (one to hold the monitor, one to operate the screwdriver)
Solution Approach 1:
The patent replaces the traditional screw-based mechanical connection system with a quick-release lever mechanism. The lever engages with a locking structure to secure the adapter plate to the bracket, eliminating the need for screwdrivers and manual screw tightening. This substitution maintains connection reliability while dramatically improving ease of operation, as the lever can be actuated with one hand.
Solution Approach 2:
The patent introduces a dynamic lever mechanism that transitions between locked and unlocked positions. The lever can be quickly moved to engage or disengage the locking structure, providing a dynamic connection system that is both secure when locked and easily operable when unlocking. This dynamic element resolves the contradiction by making the connection state changeable without requiring complex tools.
2Reliability
If a rotating plate with surrounding wall is added to block the slot opening, then the tab module is prevented from being accidentally removed, but the device structure becomes more complex
Solution Approach 1:
The rotating plate is designed to rotate between two positions: open (allowing tab module insertion/removal) and closed (blocking the slot opening to prevent accidental removal). This dynamic element provides anti-loosening protection without requiring a completely separate locking mechanism, thereby limiting the increase in structural complexity while achieving the desired reliability.
Solution Approach 2:
The rotating plate serves multiple functions: it acts as a barrier to prevent accidental tab module removal when closed, and it can be rotated to allow intentional installation or removal when opened. This multi-functionality reduces the need for additional dedicated components, thereby limiting the increase in device complexity while achieving reliable anti-loosening protection.

AI summary
A connecting device includes an installing seat adapted to be mounted to a supporting arm device and defining a slotting space that has a slot opening, a tab module disposed removably in the slotting space and adapted to be removably connected to a monitor, and a rotating plate coupled rotatably to the installing seat, and having a surrounding wall that is formed with a surrounding wall opening. When the rotating plate is in an opened position, the surrounding wall opening is registered with the slot opening of the slotting space to allow the tab module to move out of the slotting space. When the rotating plate is in a closed position, the surrounding wall opening is away from the slot opening, and the surrounding wall blocks the slot opening so that the tab module is not allowed to be removed from the slotting space.
