Display Support Plate Using Segmented Sheet Metal Cylinders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manufacturing large display apparatuses with high-strength support structures that can accommodate complex shapes for holding components like display panels and optical sheets is challenging due to limitations in mold shapes and processing capabilities during extrusion or pultrusion molding.
Innovation Solution
A display apparatus design featuring a support plate with a support cylinder made of sheet metal members, including hook-shaped and L-shaped or crank-shaped sections, which can be easily formed and combined through pressing or bending to enhance strength and accommodate various components, allowing for improved structural integrity and ease of manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a large display panel and support plate are used to manufacture a large display apparatus, then the display screen size is increased, but the strength requirement of the support plate increases making it difficult to process
Solution Approach 1:
The support plate is divided into a base plate and multiple support cylinders. The support cylinders are separately formed from sheet metal members and then combined with the base plate, allowing each component to be manufactured independently and assembled together to form the complete support structure.
Solution Approach 2:
The support plate is constructed as a composite structure combining a base plate and support cylinders made from sheet metal members. This composite design provides the necessary strength for large display apparatus while maintaining manufacturability through separate component fabrication and assembly.
2Strength
If extrusion molding or pultrusion molding is used to form the chassis, then the chassis has high strength, but the steel pipe dimension is limited by press machine processing capability
Solution Approach 1:
The support cylinders are segmented into multiple sheet metal members that are formed separately and then combined. This allows each member to be manufactured within the processing capabilities of standard equipment, while the assembled structure achieves the required size and strength.
3Adaptability or versatility
If a mold is used to form structures in the chassis during extrusion molding, then components can be held, but the mold shape constraints make it difficult to achieve the desired structure
Solution Approach 1:
The holding structures are formed as separate features on individual sheet metal members rather than attempting to incorporate complex multi-functional features into a single molded component. This segmentation allows for simpler individual parts that can be assembled to create the complete holding structure.
Solution Approach 2:
The sheet metal members are formed with features such as hooks, protrusions, and recesses that enable self-alignment and self-securing during assembly. The structures are designed to work together through their inherent geometric features rather than requiring complex external fastening mechanisms.
4Strength
If the support plate strength is increased to support large display panels, then the structural integrity is improved, but the manufacturing complexity and cost increase
Solution Approach 1:
The support plate is segmented into a base plate and multiple support cylinders made from standard sheet metal members. This segmentation allows each component to be manufactured using conventional, cost-effective sheet metal forming processes rather than requiring expensive custom molds or specialized heavy-duty manufacturing equipment.
Solution Approach 2:
The support structure utilizes standard sheet metal thicknesses and conventional forming parameters that are within the capability of typical manufacturing equipment. By designing the support cylinders with standard dimensions and forming them from available sheet metal stock, the manufacturing process remains simple and cost-effective while achieving the required strength.
