Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices face issues with rigidity, leading to deformation or damage due to tilting or load, which existing structures fail to adequately address.
Innovation Solution
The implementation of a bracket system that includes a module cover with a rigid part and a bar fixing part, coupled with a mount and a coupling part, enhances the torsional and bending rigidity of the display device's frame, minimizing deformation and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional frame structure is used, then the device is simple to manufacture, but the rigidity is insufficient leading to deformation under load or tilting
Solution Approach 1:
The frame is divided into multiple segments including a first frame, second frame, middle cabinet, and back cover that can be separately manufactured and then assembled. This segmentation allows each part to be optimized for strength while maintaining manufacturing simplicity through modular construction.
Solution Approach 2:
The middle cabinet is disposed between the first and second frames, and the back cover is coupled to the rear of the middle cabinet, creating a nested structure where components are housed within one another. This nesting approach increases rigidity through layered support while minimizing the overall footprint and simplifying assembly.
2Stability of the object's composition
If the frame structure is strengthened to prevent deformation, then the rigidity improves, but the manufacturing complexity increases
Solution Approach 1:
The coupling parts are provided in advance on the frames and middle cabinet during manufacturing, with predetermined coupling holes and coupling protrusions. This preliminary preparation of coupling features allows for rapid final assembly while ensuring structural integrity, as the strength-critical components are pre-formed rather than assembled under field conditions.
Solution Approach 2:
The middle cabinet serves as an intermediary component that couples the first and second frames together, providing a stable platform for mounting electronic parts. This intermediary structure distributes mechanical loads across multiple connection points, enhancing overall structural stability while simplifying the assembly process through a modular intermediate element.
3Reliability
If additional support structures are added to prevent damage from tilting, then the reliability improves, but the device complexity increases
Solution Approach 1:
The back cover serves multiple functions: it provides structural support to prevent tilting and damage, houses electronic parts, and completes the enclosure. This multi-functionality approach increases reliability through enhanced support capabilities while avoiding the need for separate dedicated support structures, thereby maintaining simplicity.
Solution Approach 2:
The support structure extends in multiple spatial dimensions, with the middle cabinet and back cover creating a three-dimensional framework that resists tilting forces from various directions. By utilizing vertical and depth dimensions in addition to horizontal support, the structure achieves comprehensive anti-tilting protection without requiring excessive horizontal bracing elements.

AI summary
A display device includes: a module cover; a display panel which is positioned in front of the module cover, and is coupled to the module cover; a frame which surrounds a side surface of the module cover, the frame including a first frame adjacent to one side of the module cover and a second frame adjacent to the other side of the module cover opposite to the one side of the module cover; a bar which is positioned behind the module cover, extends long between the first frame and the second frame, and is coupled to the first frame and the second frame; and a mount which is positioned behind the module cover, adjacent to the one side of the module cover, and is coupled to the bar, wherein the mount is coupled to the first frame and the module cover.
