Display Stand Lifting Mechanism With Triggered Load Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices with lifting functions fail to suspend objects like headsets or video cameras due to sliding issues when additional loads are mounted on the display screen.
Innovation Solution
A lifting mechanism comprising a lifting base, stopping component, triggering component, and elastic component, which allows the display screen to be suspended in a free state without additional load and a locked state with additional load by switching between states using the triggering component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display screen is designed with a lifting function using only a constant-force extension component, then the display screen can be suspended without additional load, but the display screen slides down and cannot be suspended when additional objects are mounted
Solution Approach 1:
The lifting mechanism dynamically switches between two states: a free state where the display screen can move freely for adjustment, and a locked state where the stopping component engages with the inner wall to prevent downward movement. This dynamic state change allows the mechanism to adapt to different load conditions, providing reliable suspension for both lightweight and heavy configurations.
Solution Approach 2:
The lifting mechanism is segmented into distinct functional components: a constant-force extension component for providing continuous supporting force, a stopping component for engagement with the inner wall, and a triggering component for state switching. This segmentation allows each component to specialize in its function, ensuring reliable suspension under varying loads.
2Adaptability or versatility
If a stopping component is added to enable locked state for additional load, then the suspending function with additional load is improved, but the device complexity increases
Solution Approach 1:
The stopping component and triggering component are integrated into a compact assembly that works in conjunction with the existing constant-force extension component. The triggering component utilizes the elastic component's restoring force to automatically reset the stopping component, merging multiple functions into a coordinated system that adds capability without excessive complexity.
Solution Approach 2:
The elastic component provides automatic resetting of the stopping component through its restoring force. When the triggering component releases the stopping component, the elastic component automatically returns it to its initial position, eliminating the need for additional actuation mechanisms and reducing overall system complexity.

AI summary
A lifting mechanism and a display device having the same are provided. The lifting mechanism is suitable for being arranged in a supporting stand of the display device. The lifting mechanism comprises a lifting base, a stopping component disposed in the lifting base, a triggering component movably connected to the lifting base, and an elastic component connected to the lifting base and the stopping component. When the triggering component is driven to drive the stopping component, the stopping component moves to press against an inner wall of the supporting stand so that the lifting base is fixedly positioned in the supporting stand. When the triggering component is driven to release the stopping component, the stopping component moves away from the inner wall of the supporting stand by a restoring force of the elastic component so that the lifting base can be lifted of lowered in the supporting stand.
