Display Stand Holder Latch Mechanism for Easy Port Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display stands are cumbersome due to their large size and weight, making it difficult for users to access signal input ports, especially those located at the back, and cannot be easily flipped to a vertical state without risking contact with the placement plane, limiting the ability to insert or remove signal lines.
Innovation Solution
A display stand holder with a stand member, base, pivot member, and latch device that allows the display to be tilted forward and rearward by limited angles, enabling the display to be flipped to a horizontal state for signal connector insertion or removal without moving the entire display, using a stop pin mechanism for easy operation and quick fastening or release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display is moved to access signal input ports, then signal line insertion and removal is enabled, but the large size and weight of the display make it difficult to move
Solution Approach 1:
The display system is segmented into a stationary display body and a movable base assembly. The base can be independently moved and rotated relative to the display body, allowing signal input ports to be accessed without moving the entire heavy display. The latch device further segments the base into movable and fixed portions during operation.
2Ease of operation
If the display is flipped to a vertical state to access signal ports, then signal line insertion is enabled, but displays with large width contact the placement plane and cannot be flipped
Solution Approach 1:
Instead of flipping the display horizontally (2D rotation), the base is designed to move vertically along the stand member and rotate in a vertical plane. This dimensional change allows wide displays to be accessed without contacting the placement plane, as the motion occurs in a different spatial dimension.
3Ease of operation
If the display is flipped to access back signal ports, then signal line removal is enabled, but the display cannot be easily returned to original position
Solution Approach 1:
The latch device enables self-service operation where users can easily latch and unlatch the base without complex tools or mechanisms. The elastic member provides automatic engagement and release functionality, allowing the base to be easily returned to its original position after signal line operations.
4Reliability
If a latch device is added to control base rotation, then rotation range is limited, but the device complexity increases
Solution Approach 1:
The latch function is extracted as a separate, simple device independent from the main base structure. The latch device with its stop pin and limiting notches is added as a minimal-component mechanism that provides reliable rotation control without significantly increasing overall device complexity.
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
Enables convenient insertion and removal of electrical signal connectors without turning over the display, allowing the display to be easily adjusted back to a vertical state, improving user accessibility and reducing the risk of display contact during flipping.
Implementation Method 1
the elastic member is normally compressed between the sliding block and the base to push the sliding block toward the upper end
Implementation Method 2
the at least one pivot plate is pivotally connected to the base

AI summary
A display stand holder includes a stand member, a base, a pivot member, and a latch device. The stand member is configured to be disposed on a planar surface. The lower end of the stand member is configured to be disposed on the planar surface. The base is slidably disposed in the stand member. The pivot member includes a mounting plate and at least one pivot plate. The pivot plate is pivotally connected to the base. The latch device includes a stop pin and an actuator. The stop pin is normally embedded into the limiting notch to limit a range of rotation of the pivot member relative to the base. The actuator is configured to push the stop pin to escape from the limiting notch, allowing the pivot member to further rotate to cause the mounting plate to be parallel to the planar surface.
