Display Back Cover Frame Structure for Slim Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses face challenges in achieving a slim thickness while maintaining rigidity and assembly ease, with plastic materials limiting thinness and metal materials prone to deformation.
Innovation Solution
A display apparatus design featuring a cover frame with a quadrangular-shape edge portion and inward reinforcing portions, coupled with a flexible cover sheet, uses hook coupling for assembly and magnetic attraction to secure rigidity and slimness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a plastic material is used for the back cover, then assembly with the display module is facilitated and post-processing is obviated, but achieving a thin thickness is difficult due to plastic injection processing characteristics
Solution Approach 1:
The back cover is divided into two separate components: a thin cover body made of plastic material for easy assembly, and a separate reinforcing frame structure. This segmentation allows the plastic cover to achieve thinness while the metal frame provides the necessary structural support, resolving the contradiction between thinness and manufacturing ease.
Solution Approach 2:
The back cover employs a composite structure combining plastic material (for the cover body) and metal material (for the reinforcing frame). This composite approach leverages the advantages of both materials: the plastic provides ease of assembly and thinness, while the metal provides rigidity and structural strength, overcoming the limitations of each material used alone.
2Length of stationary object
If a thin metal material is used for the back cover, then a slim thickness is achieved, but deformation due to denting or bending occurs during handling, making it difficult to secure appearance quality
Solution Approach 1:
The back cover is segmented into a thin metal cover body and a separate reinforcing frame structure. The thin metal cover achieves the desired slimness, while the reinforcing frame prevents deformation during handling, thus maintaining appearance quality without sacrificing thickness.
Solution Approach 2:
The back cover uses a composite structure with a thin metal cover body combined with a reinforcing frame (made of plastic or metal). This composite design allows the metal cover to be thin while the reinforcing frame provides the necessary rigidity to prevent denting and bending, ensuring both slimness and appearance quality.
3Strength
If a reinforcing structure is added to the back cover, then rigidity is improved, but the thickness increases and assembly complexity increases
Solution Approach 1:
The reinforcing structure is segmented as a separate component (reinforcing frame) rather than being integrated into the back cover body. This allows the reinforcing structure to be added only where needed to provide rigidity, while maintaining simple assembly through the separation of functions and reducing overall structural complexity.
Solution Approach 2:
The reinforcing frame is positioned at specific locations on the back cover where additional rigidity is most needed, rather than uniformly distributing reinforcement throughout the entire structure. This localized approach provides necessary strength while minimizing added complexity and maintaining a slim overall profile.
