Display Receiving Module Hemming Structure Bending Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Slim display devices, such as mobile LCD devices, face challenges in enhancing strength against external forces like bending and twisting stresses due to the thinning of LCD panels and bottom chassis, which limits their durability against impacts.
Innovation Solution
A receiving module structure featuring a receiving frame and container with a hemming structure in the sidewalls, where the second side plate is bent to face the outer surface of the first side plate, providing increased strength and stability by forming a double-walled structure that enhances resistance to bending and twisting stresses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the thickness of LCD panel and bottom chassis is reduced to make the device slim, then the device becomes thinner and lighter, but the strength against external forces such as bending and twisting stresses decreases
Solution Approach 1:
The patent applies dimensionality change by transforming the flat sidewall structure into a hemming structure with bent portions extending in multiple directions. The sidewall includes a first bent portion extending in a first direction and a second bent portion extending in a second direction perpendicular to the first direction, creating a three-dimensional reinforced structure from a two-dimensional plane, thereby increasing strength without adding thickness
Solution Approach 2:
The patent employs curvature by forming bent portions in the sidewall structure. The hemming structure includes bent portions that curve in specific directions, distributing stress more effectively compared to straight edges. The curved geometry of the bent portions helps resist deformation under external forces while maintaining a slim profile
2Ease of manufacture
If traditional coupling structures are used to fasten components, then assembly is simple, but the strength against external forces such as bending stress is insufficient
Solution Approach 1:
The patent applies segmentation by dividing the sidewall into multiple functional portions: a first sidewall portion, a first bent portion, a second sidewall portion, and a second bent portion. Each segment serves a specific structural function, and the cumulative effect of these segmented portions creates a reinforced hemming structure that resists bending stress while maintaining manufacturing simplicity
Solution Approach 2:
The patent employs composite structural design by combining multiple material layers and structural elements in the receiving container. The container includes a bottom plate and sidewalls with hemming structures, creating a composite structure that leverages the strengths of different components to achieve high bending strength without complex assembly procedures

AI summary
A receiving module for a display device includes a receiving frame and a receiving container. The receiving frame includes a bottom part and a plurality of side parts extending from a peripheral portion of the bottom part creating a receiving space. The receiving container includes a bottom plate and a plurality of sidewalls. The bottom plate is disposed on the bottom part. Each of the sidewalls includes a first side plate extending from an edge portion of the bottom plate and coupled to a corresponding side part to face an outer surface of each of the side parts, and a second side plate bent at an upper end of the first side plate to face an outer surface of the first side plate. Thus, the strength of a display device against an external force, such as a bending stress or a twisting stress, may be improved.
