Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses require complex and costly assembly processes due to the need for separate coupling members or fixing members, which increases weight and thickness, and do not efficiently protect the display panel and backlight unit.
Innovation Solution
A display apparatus design featuring a mold frame, top mold, bottom bracket, and coupling members with snap-fit shapes that allow for direct assembly and fixation without separate coupling members, reducing assembly time and weight while providing protection for the display panel and backlight unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate coupling members or fixing members are used to assemble the display apparatus, then the assembly is more secure and reliable, but the device complexity, weight, and thickness increase
Solution Approach 1:
The patent integrates the coupling function directly into the mold frame by forming coupling protrusions and coupling holes as integral parts of the frame structure. This merging of the coupling function into the existing mold frame eliminates the need for separate coupling members while maintaining assembly security and reliability.
2Reliability
If separate coupling members or fixing members are used to assemble the display apparatus, then the assembly is more secure and reliable, but the weight increases
Solution Approach 1:
The coupling protrusions and coupling holes are formed as integral parts of the mold frame structure, eliminating the need for separate coupling members. This merging approach reduces the overall weight of the display apparatus while maintaining secure assembly through the built-in coupling mechanism.
3Reliability
If separate coupling members or fixing members are used to assemble the display apparatus, then the assembly is more secure and reliable, but the overall thickness increases
Solution Approach 1:
The coupling protrusions and coupling holes are integrated directly into the mold frame structure, eliminating the need for separate coupling members that would add to the overall thickness. This merging approach maintains secure assembly while minimizing the thickness of the display apparatus.
4Reliability
If separate coupling members or fixing members are used in the assembly process, then the assembly is more secure and reliable, but the assembly time and cost increase
Solution Approach 1:
The coupling protrusions and coupling holes are formed as integral parts of the mold frame during manufacturing, eliminating the need for separate coupling members and reducing assembly steps. This merging approach secures the assembly while significantly reducing assembly time and manufacturing cost.
5Length of stationary object
If the mold frame corresponds to only three sides of the display panel, then the overall thickness and weight are reduced, but the protection capability may be compromised
Solution Approach 1:
The coupling protrusions and coupling holes are integrated directly into the mold frame structure, eliminating the need for separate coupling members that would add to the overall thickness. This merging approach maintains secure assembly while minimizing the thickness of the display apparatus.

AI summary
A display apparatus includes a display panel, a backlight unit, a mold frame, a bottom bracket, a top mold, and first and second coupling members. The display panel includes a display surface on which an image is displayed. The backlight unit generates and provides a light to the display panel. The mold frame supports the display panel and the backlight unit. The bottom bracket accommodates the display panel, the backlight unit and the mold frame. The top mold faces the bottom bracket and overlaps a portion of the display panel, and the display panel is between the top mold and the bottom bracket. The first coupling member couples the mold frame with the top mold, and the second coupling member couples the top mold with the bottom bracket.
