Monitor Support Hinge With Stop Mechanism for Stable Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional support structures for flat monitors lack stability during folding, leading to potential damage or instability due to the shifting gravity center when transitioning from a vertical to a horizontal state, especially when the monitor is placed at a higher location, making the folding process inconvenient and prone to falling.
Innovation Solution
A support structure with a main hinge equipped with a stop mechanism and a non-parallel four-bar linkage mechanism, utilizing auxiliary connection members and shaft rings to prevent rotation from a vertical to a horizontal state, allowing for stable folding by altering the stopping location and maintaining the original angle of the monitor, thereby preventing falling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the support structure is designed to be foldable for reducing transportation volume, then the compactness and portability are improved, but the stability during folding operation deteriorates due to gravity center shifting
Solution Approach 1:
The stop mechanism is activated in advance when the monitor reaches a predetermined angle during folding, preventing the gravity center from shifting to an unstable position. This preliminary intervention stops the harmful motion before it can cause instability or damage, resolving the contradiction between foldability and stability.
Solution Approach 2:
The stop mechanism acts as an intermediary between the folding motion and the monitor's gravity center. It mediates the folding process by introducing a controlled stopping point that prevents uncontrolled rotation, thereby maintaining stability while still allowing the folding function to be achieved.
2Ease of operation
If the monitor is allowed to rotate freely from vertical to horizontal state during folding, then the ease of operation is improved, but the risk of damage or falling increases
Solution Approach 1:
The stop mechanism provides preliminary protection by preventing the monitor from rotating beyond a safe angle. This ensures that while the monitor can be folded easily, it will not rotate to a horizontal state that could cause damage or falling, thus maintaining both ease of operation and reliability.
3Reliability
If a stop mechanism is added to prevent rotation during folding, then the stability and safety are improved, but the device complexity increases
Solution Approach 1:
The stop mechanism serves as a simple intermediary component that mediates between the folding motion and stability requirements. By introducing this relatively simple stopping function, the patent achieves improved reliability without adding excessive complexity to the overall device.

AI summary
The present invention relates to a support structure. A main hinge of the structure is installed with a stop mechanism, so when an object to be supported is placed at a higher location while being in an unfolding state, the object to be supported is restrained from being rotated from a vertical state to a horizontal folding state, thereby preventing falling due to the unstable gravity center; when a connection unit is folded towards a base, an upper end of a first auxiliary connection member links the stop mechanism to rotate for gradually altering the stopping location, so the object to be supported is enabled to be horizontally folded; as such, the object to be supported can be maintained in a stable state during the folding process, thereby preventing the occurrence of falling.
