Display Receiving Container Strength via Local Material Differentiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As liquid crystal display apparatuses increase in size, their receiving containers often suffer from reduced strength, necessitating the use of reinforcing members that add cost and complexity.
Innovation Solution
A display apparatus with a receiving container featuring a bottom portion and sidewall, incorporating first and second strength portions made of different materials and thicknesses, such as galvanized steel and aluminum, connected by laser welding, to enhance structural integrity without additional cost.

Engineering Contradiction Analysis
1Area of moving object
If the size of the liquid crystal display apparatus is increased, then the display area is improved, but the strength of the receiving container is reduced
Solution Approach 1:
The receiving container incorporates strength portions with different materials and thicknesses at specific locations. The bottom portion includes first strength portions made of high-strength material (e.g., SUS304) with greater thickness (e.g., 0.5-1.0mm), while the sidewall includes second strength portions made of different material (e.g., aluminum alloy) with different thickness (e.g., 0.2-0.5mm). This local differentiation provides enhanced strength where needed while maintaining overall container performance.
Solution Approach 2:
The receiving container is constructed using composite materials with different properties in different regions. The first strength portions use high-strength, corrosion-resistant materials like SUS304 stainless steel, while the second strength portions use lightweight materials like aluminum alloys. These different materials are joined together through welding to create a composite structure that optimizes both strength and weight for large-sized display apparatuses.
2Strength
If a reinforcing member is added to improve the strength of the receiving container, then the strength is improved, but the cost and manufacturing complexity increase
Solution Approach 1:
The strength portions are integrated directly into the receiving container structure rather than being added as separate reinforcing members. The first strength portions form part of the bottom portion, and the second strength portions form part of the sidewall, creating a unified container structure. This integration eliminates the need for additional separate reinforcing components and simplifies the overall manufacturing process.
Solution Approach 2:
The strength portions serve multiple functions simultaneously: they provide structural strength to support large display areas, act as integral parts of the receiving container walls, and eliminate the need for separate reinforcing members. The first strength portions in the bottom and second strength portions in the sidewall together provide comprehensive structural support for the entire container.

AI summary
A display apparatus includes a display panel, a light source part which generates and provides a light to the display panel, and a receiving container. The receiving container includes a bottom portion under the light source part, and a sidewall extending from the bottom portion. The bottom portion includes a first strength portion and a second strength portion. The first strength portion and the second strength portion have different strengths from each other and are continuously connected to each other.
