Monitor Support Structure 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 falling 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 errors.
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, ensuring the monitor remains stable during folding by altering the stopping location and maintaining the original angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the support structure is designed to allow folding from vertical to horizontal state, then the volume during transportation is reduced, but the stability 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 folding process before instability occurs, resolving the contradiction between volume reduction and stability maintenance.
Solution Approach 2:
The support structure transitions from a static configuration to a dynamic folding state, where the stop mechanism adaptively engages at specific angles. This dynamic control allows the system to maintain stability during the folding process by preventing rotation beyond the predetermined safe angle.
2Ease of operation
If the monitor is placed at a higher location during unfolding state, then the elevation angle adjustment is improved, but the reliability deteriorates due to increased risk of falling
Solution Approach 1:
The stop mechanism provides preliminary protection by engaging at a predetermined angle before the monitor can fall. This prevents the harmful effect of falling even when the monitor is positioned at higher locations, maintaining reliability while allowing ease of operation.
3Stability of the object's composition
If a stop mechanism is installed on the main hinge, then the stability during folding is improved, but the device complexity increases
Solution Approach 1:
The stop mechanism is merged with the existing main hinge structure, integrating the safety function into the already-present rotational joint. This combination adds stability functionality without requiring a completely separate mechanism, thereby limiting the increase in device complexity.
4Stability of the object's composition
If the non-parallel four-bar linkage mechanism is used, then the stability during folding is improved, but the device complexity increases
Solution Approach 1:
The non-parallel four-bar linkage mechanism uses asymmetric linkages to control the folding motion. This asymmetric design creates a mechanical advantage that naturally guides the monitor through a controlled folding path, improving stability while using simple连杆 components rather than complex active control systems.

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.
