Display Container Member with Mold Frame for Impact Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container members for display panels either become bulky to absorb external impacts effectively or fail to prevent deformation due to lack of rigidity, and may damage the panel during assembly.
Innovation Solution
A container member design featuring a metal frame with a bottom opening and a mold frame interposed between the metal frame and the display panel, along with a buffer tape, which provides structural reinforcement and minimizes deformation by attenuating external impacts, while maintaining a compact size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a metal frame is used to prevent deformation by external stress, then rigidity is improved, but the display panel may be damaged during assembly process
Solution Approach 1:
A mold frame is introduced as an intermediary component between the metal frame and the display panel. The mold frame serves as a buffer that absorbs assembly forces and prevents direct contact between the rigid metal frame and the fragile display panel, thereby preventing damage while maintaining structural support.
Solution Approach 2:
The mold frame is positioned in advance between the metal frame and display panel to provide cushioning protection. This pre-positioned buffer structure prevents damage before it can occur during the assembly process, rather than attempting to protect the panel after damage has been inflicted.
2Reliability
If the metal frame is made sufficiently thick to absorb external impact, then impact resistance is improved, but the entire size is increased
Solution Approach 1:
The impact absorption function is segmented between two components: the metal frame provides structural support and primary impact resistance, while the mold frame provides secondary cushioning. This segmentation allows each component to be thinner than a single thick frame would require, reducing overall size while maintaining impact resistance.
Solution Approach 2:
The container member uses a composite structure combining metal frame and mold frame materials with different mechanical properties. The metal frame provides rigidity and primary impact resistance, while the mold frame material provides complementary cushioning, creating a synergistic effect that improves impact resistance without increasing size.
3Ease of manufacture
If a mold frame is used to facilitate assembly and minimize size, then ease of manufacture and compactness are improved, but rigidity is insufficient to prevent deformation
Solution Approach 1:
The metal frame and mold frame are merged into a cooperative structure where the metal frame provides the necessary rigidity and structural support, while the mold frame provides assembly facilitation and size minimization benefits. Together, they achieve both ease of manufacture and sufficient rigidity.
Solution Approach 2:
The metal frame serves multiple functions: providing structural support, preventing deformation through its rigidity, and working in conjunction with the mold frame to enable easy assembly. This multi-functionality allows a single component to address multiple requirements that would otherwise require separate specialized components.

AI summary
A display device that includes a display panel and a container member that accommodates the display panel, where the container member can effectively absorb an external impact to sufficiently protect the display panel from damage and minimize deformation caused by an external stress, a method of manufacturing the same. The container member includes a metal frame including a space that accommodates the display panel, a plurality of sides and a bottom having a first opening; and a mold frame arranged between the sides of the metal frame and sides of the display panel. The display device may also include a buffer tape within the first opening. The mold frame is preferably produced by an injection molding technique.
