Display Stand Coupling Structure to Prevent Support Bar Shaking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display stands often suffer from instability, leading to shaking and potential damage to the display module due to an unsecured coupling between the base and the support bar.
Innovation Solution
A stand design featuring a movement preventing unit with a moving block and guide block, which includes a coupling pin to secure the support bar to the base, reducing the gap between them and preventing shaking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the coupling between the base and the support bar is not secured, then the stand structure is simpler and easier to assemble, but the support bar shakes and the display panel may be damaged
Solution Approach 1:
The coupling structure is divided into separate components: a coupling hole in the base and a protrusion on the support bar. This segmentation allows for easier assembly while maintaining stability, as the components can be independently manufactured and then joined together through a simple insertion motion.
Solution Approach 2:
The coupling hole and protrusion are pre-formed during manufacturing, so that when assembly occurs, the components are already prepared for stable coupling. This preliminary preparation eliminates the need for complex assembly procedures while ensuring reliable connection between the base and support bar.
2Object-affected harmful factors
If a secure coupling structure is implemented, then the shaking is prevented and display panel safety is improved, but the manufacturing complexity increases
Solution Approach 1:
The coupling function is extracted as a separate mechanical feature (protrusion and coupling hole) rather than being integrated into a complex joint. This extraction simplifies manufacturing by allowing standard drilling and machining operations to create the coupling elements, while still providing secure connection to prevent shaking and damage.
3Stability of the object's composition
If the movement preventing unit is added to reduce the gap, then the stand stability is improved, but the device complexity increases
Solution Approach 1:
The movement preventing unit is merged with the existing coupling structure. The protrusion on the support bar serves dual functions: it provides the coupling connection and simultaneously acts as the movement preventing unit by physically blocking the opening. This merging eliminates the need for separate complex mechanisms while maintaining stand stability.

AI summary
The present disclosure relates to a stand having an improved structure to stably support a display module and a display apparatus including the same. The stand includes a base, a support bar on which the display module is mounted, the support bar including an opening and being coupled to the base, and a movement preventing unit configured to reduce a gap between the base and the support bar and including a moving block configured to protrude through the opening to be in contact with an inner surface of the base.
