Segmented Top Case Design for Display Bezel Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in reducing the bezel area while maintaining structural integrity and aesthetic appeal, as traditional top cases require significant material and are not sufficiently reinforced.
Innovation Solution
A display device design featuring a top case with a main frame and a sub frame, where the top case is composed of separated metal plates joined by thermoplastic resin, and the sub frame is made of thermoplastic resin with a colored pattern, combined with a metal main frame to enhance strength and beauty.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single top case is used to cover the display device, then the structure is simple, but the material cost increases and structural reinforcement is insufficient
Solution Approach 1:
The top case is divided into multiple separate top cases, each covering different regions of the display device. This segmentation allows each top case to be optimized independently for strength and design, while collectively providing comprehensive coverage and reinforcement without requiring a single large, costly piece of material.
2Strength
If the top case is elongated in the bezel area to strengthen it, then structural strength improves, but the material cost increases
Solution Approach 1:
Instead of using one large elongated top case that requires more material, the structure is segmented into multiple smaller top cases. Each top case can be optimized to the minimum necessary size for its specific location, reducing total material usage while maintaining or improving overall structural strength through distributed reinforcement.
Solution Approach 2:
Different regions of the display device receive different levels of reinforcement based on their specific structural needs. The multiple top cases allow for localized strengthening where required, rather than uniformly elongating the entire top case structure, thus optimizing material distribution and reducing overall material cost.
3Strength
If additional connections are added to mount top case parts, then structural strength improves, but the manufacturing complexity increases
Solution Approach 1:
The multiple top cases are designed to be combined with each other and with the display device structure in an integrated manner. The connections between top cases are merged with the overall mounting structure, reducing the number of separate connection components needed and simplifying the assembly process while maintaining structural strength.
