Display Device Assembly Holder Resisting Case Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As larger televisions are developed, the increased weight of the display module can cause the case to deform, exposing the iron frame and compromising the aesthetic design due to insufficient material strength in the case to bear the weight of the display module.
Innovation Solution
A display device design featuring a display module with an assembly holder and a front case, where the assembly holder includes a joint portion and a first withstanding portion that abuts against a second withstanding portion in the front case, providing a reacting force to resist deformation forces and maintain assembly reliability, thus preventing exposure of the outer frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the case material strength is increased to bear the weight of the display module, then the case deformation is reduced, but the manufacturing cost and complexity increase
Solution Approach 1:
The support function is segmented from the case structure and transferred to the assembly holder, which is a separate component. The assembly holder includes a first withstanding portion that specifically supports the display module weight, while the case maintains its original lightweight design. This segmentation allows the case to remain simple while the assembly holder bears the mechanical load.
Solution Approach 2:
The assembly holder acts as an intermediary component between the display module and the case. It includes a joint portion that connects to the display module and a second withstanding portion that abuts against the case, transferring the load through this intermediate structure rather than requiring the case itself to be strengthened.
2Strength
If the case material strength is increased to bear the weight of the display module, then the case deformation is reduced, but the manufacturing cost increases
Solution Approach 1:
The load-bearing function is segmented into a separate assembly holder component, allowing the case to be manufactured from standard materials at standard costs. The assembly holder, which bears the mechanical load, can be manufactured independently and attached to the case, separating the structural support requirement from the case manufacturing process.
3Productivity
If the assembly holder and front case are assembled without additional support structures, then the assembly process is simple, but the case deforms under the weight of the display module
Solution Approach 1:
The support function is merged with the assembly holder component, which is then integrated with the case assembly. The assembly holder includes withstanding portions that work together with the case to form a combined load-bearing structure, maintaining simple assembly procedures while achieving adequate support capacity.

AI summary
A display device includes a display module, an assembly holder and a front case. The display module has a front surface, a rear surface, a side surface, and a display area. The front surface and the rear surface are located at two opposite sides of the display module. The side surface connects between the front surface and the rear surface. The display area is located at the front surface. The assembly holder includes a joint portion and a first withstanding portion. The joint portion is arranged on the side surface. The first withstanding portion is connected to the joint portion. The front case includes a first plate member, a second plate member, and a second withstanding portion. The first plate member is connected to the second plate member. The second withstanding portion is located on the first plate member and has a groove.
