Display Device Module Cover Bending Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices face the challenge of module covers being easily bent, which can lead to structural integrity issues and functionality problems, especially around fastening holes.
Innovation Solution
Incorporating a cushion in the vicinity of the fastening holes on the module cover, which is designed with multiple layers of varying thickness, including a depressed part for the cushion, to enhance structural support and prevent bending.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the module cover is made thin and lightweight, then the display device can be ultra-slim, but the module cover becomes easily bent and loses structural integrity
Solution Approach 1:
The module cover is designed with varying thickness: the central area is thin to maintain ultra-slim profile, while the peripheral area (within 10mm of edges) is thicker (1.5-2mm) to provide structural strength and prevent bending. This local quality differentiation resolves the contradiction between thinness and strength.
Solution Approach 2:
The module cover is segmented into different thickness zones: a thin central region and a thicker peripheral region. This segmentation allows each zone to serve its specific function - the thin center reduces overall thickness while the thick perimeter provides structural support and bending resistance.
2Adaptability or versatility
If fastening holes are provided in the module cover for wall mounting, then the display device can be installed on walls, but the module cover becomes vulnerable to bending around the hole areas
Solution Approach 1:
Ribs are pre-formed around the fastening holes to provide structural reinforcement before the fastening operation. These ribs act as cushions that prevent bending and maintain structural integrity in the vulnerable hole areas, allowing wall mounting without compromising stability.
Solution Approach 2:
The module cover incorporates ribs (structural elements) integrated with the cover body (base material) to create a composite structure. The ribs provide additional stiffness and strength around fastening holes while maintaining the overall thin profile of the cover.
3Volume of moving object
If the module cover is made thin to achieve ultra-slim design, then the display device profile is improved, but the cover requires additional reinforcement structures that increase complexity
Solution Approach 1:
The reinforcement features (ribs and variable thickness zones) are merged into the module cover as integral parts rather than separate components. This combining approach provides necessary structural support while avoiding the complexity of additional separate reinforcement pieces, maintaining a clean ultra-slim design.
