Curved Screen Bracket Support Block for Display Impact Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing middle frames for curved screen modules in mobile phones fail to provide adequate support for the arc region, leading to low structural strength and a higher likelihood of abnormal display issues such as broken bright spots and black spots when impacted.
Innovation Solution
The electronic device incorporates a bracket with a support portion that includes a support block, which is fixed to the bracket side portion and supports the edge portion of the curved screen module, enhancing impact resistance and structural reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional middle frame is used to support the curved screen module, then the flat region is well supported, but the arc region at the edge receives insufficient support, resulting in low structural strength and proneness to abnormal display
Solution Approach 1:
The support structure is divided into multiple segments: the middle frame body for supporting the flat region, and separate arc region support structures (including support blocks and buffer rubber pieces) for supporting the curved edge regions. This segmentation allows each component to be optimized for its specific function, providing adequate support to the arc region without complicating the entire frame structure.
Solution Approach 2:
Different support characteristics are applied to different regions of the curved screen module. The middle frame provides rigid support for the flat region, while arc region support blocks with buffer rubber pieces provide flexible, impact-absorbing support for the curved edges. This local differentiation of support quality ensures optimal protection where needed without unnecessary complexity elsewhere.
2Reliability
If the middle frame is designed to fit the arc region, then support for the edge is improved, but the structural complexity and manufacturing difficulty increase
Solution Approach 1:
Instead of designing a complex integrated middle frame that fits the arc region, the support function is segmented into separate components: standard middle frame structures and independent arc region support blocks. These can be manufactured separately using conventional processes and then assembled, maintaining manufacturing simplicity while achieving reliable arc region support.
Solution Approach 2:
Buffer rubber pieces are introduced as intermediary elements between the arc region support blocks and the curved screen module. These rubber intermediaries provide the necessary compliance and cushioning for reliable support, while the support blocks themselves can be manufactured using standard processes, thus maintaining ease of manufacture while improving support reliability.
3Object-affected harmful factors
If additional support structures are added to the arc region, then impact resistance is improved, but the device complexity increases
Solution Approach 1:
Impact resistance enhancement is applied locally only to the arc regions where it is most needed, rather than throughout the entire structure. Arc region support blocks with buffer rubber pieces are positioned specifically at the curved edges to absorb impacts, while the flat region continues to rely on the standard middle frame. This localized approach improves impact resistance with minimal increase in overall structural complexity.
Solution Approach 2:
Buffer rubber pieces are pre-installed between the arc region support blocks and the curved screen module to provide beforehand cushioning. This cushioning layer is designed to absorb impact forces before they reach the fragile display components, enhancing impact resistance in advance. The cushioning elements are integrated into the support structure without significantly increasing overall device complexity.

AI summary
This application provides an electronic device which may be a mobile phone. The electronic device includes a display module and a bracket, where the display module includes a module body portion and a module side portion; the module side portion is connected to the module body portion and is bent relative to the module body portion, and the module side portion and the module body portion enclose an accommodating space; the bracket includes a bracket body portion, a bracket side portion, and a support portion; the bracket body portion is located inside the accommodating space and is close to the module body portion to support the module body portion; the bracket side portion is connected to the bracket body portion, forming an included angle with the bracket body portion, and the bracket side portion is close to the module side portion; and the support portion is fixed to the bracket side portion to support the module side portion. The solution of this application can reinforce a region with low structural strength of the display module, enhancing impact resistance of the region and reducing risks of abnormal display of the display module when an impact is experienced.
