Display Rear Cover Mounting Structure to Prevent Frame Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The deformation of the rear cover in display devices due to the deformation of the frame chassis affects the appearance of the display device.
Innovation Solution
A frame chassis with a first frame and a second frame having free ends spaced apart to prevent deformation, coupled to the rear cover and rear chassis using a detachable mechanism to minimize deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the frame chassis is directly coupled to the rear cover, then the assembly is simple, but the rear cover deforms when the frame chassis deforms
Solution Approach 1:
The frame chassis is divided into multiple independent frame members (first frame member, second frame member, third frame member, fourth frame member) instead of a single rigid structure. This segmentation allows each member to move independently, preventing deformation transmission to the rear cover while maintaining structural support functionality.
Solution Approach 2:
The frame members are designed with movable joints connecting them to the rear cover, transforming the static rigid connection into a dynamic system. This allows the frame members to adjust their positions independently when subjected to external forces, absorbing deformation without transmitting it to the rear cover.
2Strength
If the frame chassis uses a rigid structure, then it provides strong support, but it cannot accommodate movement and causes deformation
Solution Approach 1:
The rigid frame chassis is segmented into multiple independent frame members connected by joints. This segmentation maintains the overall support capability while allowing individual members to move independently, accommodating external forces without compromising structural integrity.
Solution Approach 2:
Movable joints act as intermediaries between the frame members and the rear cover. These joints provide the necessary flexibility to accommodate movement while maintaining the support function, serving as a mediator between the rigid support requirement and the movement accommodation need.
3Volume of moving object
If the frame members are connected closely, then the structure is compact, but deformation is transmitted to the rear cover
Solution Approach 1:
The compact frame structure is segmented into multiple members with movable connections. This segmentation allows the structure to maintain compactness while enabling independent movement of each member, preventing deformation transmission to the rear cover through the movable joint mechanism.
