LCD Receiving Container Strength Enhancing Means
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ultra-thin and ultra-compact liquid crystal display (LCD) panels face strength limitations, making it difficult for the mold frame and bottom chassis to adequately protect the backlight assembly and LCD panel from external impacts.
Innovation Solution
A receiving container with a mold frame and a strength enhancing means, including a base plate and strength enhancing portions, is designed to absorb external impacts, featuring a connecting portion through a hole and formed from plastic and metal materials respectively, to provide enhanced protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the LCD panel is made ultra-thin and ultra-compact, then the size and weight are reduced, but the strength and impact resistance deteriorate
Solution Approach 1:
The receiving container is divided into multiple portions: a mold frame portion and a strength enhancing means portion. This segmentation allows each part to perform its specific function - the mold frame provides structural support while the strength enhancing means provides impact resistance, resolving the contradiction between compact size and strength.
Solution Approach 2:
The receiving container combines plastic material (mold frame) with metal material (strength enhancing means) to create a composite structure. This composite approach allows the lightweight plastic to maintain compact size while the metal reinforcement provides the necessary impact resistance and strength.
2Strength
If the mold frame is made larger and more substantial, then the impact protection is improved, but the overall device size and weight increase
Solution Approach 1:
Instead of making the entire mold frame substantially larger, the strength enhancing means is applied locally at specific positions where impact protection is most needed. The strength enhancing portions are strategically positioned to provide maximum protection while maintaining the overall compact size of the device.
Solution Approach 2:
The strength enhancing means is nested within or integrated with the mold frame structure. The base plate is positioned at the bottom of the receiving container, and the strength enhancing portions are arranged within the available space, allowing enhanced protection without increasing the external dimensions of the device.
3Ease of manufacture
If a simple mold frame structure is used, then the manufacturing complexity is reduced, but the impact absorption capability is insufficient
Solution Approach 1:
The strength enhancing means is prepared separately as a pre-manufactured component (base plate with strength enhancing portions) before being integrated with the mold frame. This preliminary preparation allows for optimized impact absorption design while keeping the main mold frame manufacturing simple and straightforward.
Solution Approach 2:
The strength enhancing means acts as an intermediary component between the external impact forces and the internal contents (backlight assembly and LCD panel). It absorbs and distributes impact forces before they reach the fragile components, providing enhanced protection without complicating the overall manufacturing process.

AI summary
A receiving container, a method of manufacturing the receiving container, and a liquid crystal display having the same are provided. The receiving container includes a mold frame and a strength enhancing means. The mold frame includes a first portion and a second portion connected to the first portion. The strength enhancing means includes a base plate for supporting a lower part of the backlight assembly, and a strength enhancing portion connected to at least a part of the base plate for surrounding at least a part of the second portion.
