Internal Support Plate for Display Module Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with touchscreens face structural rigidity issues due to deflection of display components under user interaction, which existing designs often address by thickening the cover glass or using air gaps for protection, limiting design flexibility and material choices.
Innovation Solution
Incorporating an internal support structure with a plate between the transparent cover and the shell, which secures the display module and other components, providing structural rigidity without the need for thickened cover glass or air gaps, allowing for a thinner, more versatile device design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the cover glass is thickened to provide structural support, then the structural rigidity is improved, but the device thickness increases and design flexibility is reduced
Solution Approach 1:
The patent divides the structural support function into two separate components: the cover glass and an internal support structure. The cover glass can be kept thin for aesthetic and design purposes, while the internal support structure (comprising a plate and frame) provides the necessary structural rigidity. This segmentation resolves the contradiction by allowing each component to be optimized independently for its specific function.
2Reliability
If air gaps are introduced to protect display components, then component protection is improved, but structural rigidity deteriorates
Solution Approach 1:
The patent employs a nested structure where the display module is positioned within the enclosure formed by the plate and frame. The plate provides a solid mounting surface for the display module, while the frame creates a protective enclosure around it. This nested arrangement allows the display components to be protected within a rigid structural framework, simultaneously achieving both component protection and structural rigidity.
3Strength
If an internal support structure is added to enhance structural rigidity, then component deflection is reduced, but device complexity increases
Solution Approach 1:
The internal support structure serves multiple functions simultaneously: the plate provides a mounting surface for the display module and contributes to structural rigidity, while the frame provides both structural support and protection for the display components. By designing a multi-functional support structure, the patent reduces device complexity compared to having separate components for each function.

AI summary
An electronic device includes an external display layer, a shell disposed opposite the external display layer, a display module component enclosed by the external display layer and the shell, and an internal support that structurally supports the display module component and the external display layer. The internal support includes a plate disposed between the external display layer and the shell.
