Display Panel Rubber Frame for Collision Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in the computer equipment industry is to improve production yield while reducing production costs, particularly in protecting display panels from direct contact and collision during manufacturing.
Innovation Solution
A display device design incorporating a rubber frame with extending portions that cover and protect the display panel edges, coupled with a backboard and casing system to prevent direct contact and collision, enhancing structural integrity and assembly stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display panel is directly exposed without protection during assembly, then the assembly process is simple and fast, but the display panel is at high risk of direct contact and collision damage
Solution Approach 1:
The rubber frame acts as an intermediary protective element between the display panel and the external environment. The extending portion of the rubber frame protrudes beyond the display panel edge, creating a buffer zone that prevents direct contact and collision with the fragile display panel during assembly and operation.
Solution Approach 2:
The rubber material inherently provides cushioning properties, and the extending portion is positioned in advance to cover the display panel edge. This pre-positioned cushioning structure absorbs potential impacts and prevents damage before it can reach the display panel.
2Reliability
If the extending portion of the rubber frame covers the display panel edge, then the risk of collision is reduced, but the structural complexity and manufacturing difficulty increase
Solution Approach 1:
The rubber frame integrates multiple functions into a single component: it provides structural support, protects the display panel edge, and guides assembly through the guiding portions. The abutting portion, supporting portion, and extending portion are combined into one continuous rubber frame structure, simplifying manufacturing compared to multiple separate protective components.
Solution Approach 2:
The rubber frame utilizes flexible material properties to achieve both protection and ease of assembly. The flexibility allows the frame to be installed without rigid precision alignment, while still providing effective protection. The material can deform slightly during assembly and then maintain its protective shape.
3Manufacturing precision
If the rubber frame includes multiple guiding portions and snapping portions for precise assembly, then the assembly precision is improved, but the device complexity increases
Solution Approach 1:
The guiding portions and snapping portions enable self-aligning and self-locating during assembly. The first and second guiding portions guide the display panel into correct position automatically, while the snapping portions provide automatic mechanical interlocking. This self-service mechanism reduces the need for complex external alignment tools or procedures.

AI summary
A display device includes a backboard, a rubber frame and a display panel. A backboard includes a base and a wall having a first end and a second end opposite to the first end. The first end connects with an edge of the base. The rubber frame includes an abutting portion, a supporting portion and an extending portion. The abutting portion locates outside the backboard and abuts against the wall. The supporting portion connects with the abutting portion and is supported at the second end. The extending portion connects with the abutting portion and extends toward outside from the backboard. The extending portion and the supporting portion are at least partially coplanar to define a connecting surface. The display panel couples with the connecting surface. An edge of the extending portion substantially aligns with or exceeds relative to the wall an edge of the display panel.
