Display Support Arm Locking Link for Safe Panel Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display modules can collide with the floor surface during rotation due to insufficient spacing, leading to potential damage.
Innovation Solution
A display apparatus with a support system that allows rotation only when the display module is spaced apart from the floor by a predetermined distance, featuring a locking mechanism that restricts rotation when close to the floor and enables it when sufficiently spaced, using a rotating link and locking link system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display module is allowed to rotate without spacing constraints, then the ease of operation is improved, but the reliability deteriorates due to potential collision with the floor surface
Solution Approach 1:
The support arm is designed to automatically move the display module to a safe position (sufficiently spaced from the floor) before enabling rotation. This preliminary positioning action prevents collision before it can occur, allowing rotation only when safe
Solution Approach 2:
A control mechanism acts as an intermediary between the rotation command and the actual rotation execution. The controller verifies the spacing condition and mediates whether rotation is permitted, preventing direct rotation that could cause collision
2Reliability
If the display module is spaced apart from the floor surface by a large distance, then the reliability is improved by preventing collision, but the area occupied by the support device increases
Solution Approach 1:
The support arm provides dynamic vertical adjustment capability, allowing the display module to be positioned at different heights. The system can adapt the spacing distance based on rotation requirements, achieving protection only when needed rather than maintaining constant large spacing
Solution Approach 2:
The vertical position parameter of the display module is made variable through the support arm's adjustable mechanism. The spacing distance can be changed dynamically to match the specific operational context, minimizing the support device footprint while maintaining protection when rotation occurs
3Reliability
If a locking mechanism is added to restrict rotation when close to the floor, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The support arm's vertical position detection system automatically triggers the locking mechanism when the display module is detected to be too close to the floor. The system serves itself by monitoring its own state and autonomously preventing unsafe rotation without requiring external intervention or complex control systems
Solution Approach 2:
A feedback mechanism monitors the vertical position of the display module and provides information to the controller. Based on this feedback, the controller automatically activates or deactivates the locking mechanism, creating a simple closed-loop control system that prevents collision while maintaining ease of operation
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
Prevents display module collisions with the floor during rotation by ensuring adequate spacing, maintaining the display module's integrity and functionality.
Implementation Method 1
The locking link may be configured to move to the locked position based on an elastic force of the elastic member when the support arm moves from the first position to the second position

AI summary
A display apparatus is provided. The display apparatus includes: a display panel; a support bracket coupled to a rear surface of the display panel and defining a locking groove; a support arm coupled to the support bracket and supporting the display panel, wherein the support arm is configured to rotate between a first and second orientations; and a support stand supporting the support arm and configured to allow the support arm to move along a vertical direction between first and second positions. The support arm includes: a rotating link configured to rotate as the support arm moves; and a locking link configured to move from a locked position in which the locking link is inserted into the locking groove to restrict rotation of the display panel, to an unlocked position in which the locking link is withdrawn from the locking groove to allow rotation of the display panel.
