Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in achieving a rigid structure while maintaining ease of coupling, which is crucial for ensuring durability and efficient assembly.
Innovation Solution
The display device incorporates a frame with an accommodating portion and extension portion, a holder, and a back cover with a curled coupling portion and reinforcing parts, allowing for a rigid structure and easy coupling by utilizing a frame and back cover design that includes a curled coupling mechanism and reinforcing elements to enhance rigidity and assembly convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional coupling structure is used, then the assembly process is simple, but the rigidity of the display device is insufficient
Solution Approach 1:
The back cover is divided into multiple functional portions: a base portion for positioning, a connecting portion for structural transition, a coupling portion for attachment, and a reinforcing part for rigidity enhancement. This segmentation allows each portion to perform its specific function optimally while collectively providing the required rigidity and ease of assembly.
Solution Approach 2:
The coupling portion is designed with a curved shape that allows it to flex during assembly and then snap into place, providing both ease of assembly and structural rigidity. The curvature enables the coupling portion to conform to the holder's geometry while maintaining strength.
2Strength
If additional reinforcing parts are added, then the rigidity is improved, but the manufacturing complexity increases
Solution Approach 1:
The reinforcing part is integrated into the back cover as a single piece rather than being a separate component. This merging of the reinforcing function into the existing back cover structure provides the required rigidity without adding separate manufacturing steps or assembly operations, thus maintaining ease of manufacture.
3Strength
If the back cover is made thicker to improve rigidity, then the structural strength increases, but the device thickness increases
Solution Approach 1:
Instead of increasing the thickness of the entire back cover uniformly, the reinforcing part is strategically positioned only where additional strength is needed - specifically in the region requiring rigidity support. This localized reinforcement provides the necessary structural strength while maintaining the overall slim thickness of the device.
