Irregular Display Guide Member for Hole Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display devices face challenges in achieving a thin bezel structure and securing fastenability between the liquid crystal panel and backlight, especially when incorporating irregular shapes or holes, which can lead to detachment, rattle noise, and light leakage.
Innovation Solution
The design incorporates a backlight unit at the lower portion of the liquid crystal panel with a lower cover that includes holes for mechanical parts, and a guide member with a cylindrical shape to secure the liquid crystal panel, allowing mechanical parts to pass through, thereby preventing detachment and noise while maintaining image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If holes are provided in the liquid crystal panel and lower cover to allow mechanical parts to pass through, then adaptability and functionality are improved, but fastenability and structural stability deteriorate
Solution Approach 1:
A guide member is introduced as an intermediary component between the liquid crystal panel and lower cover. The guide member includes a guide hole that allows mechanical parts to pass through, while simultaneously providing a mounting portion that secures the liquid crystal panel to the lower cover, thus maintaining both functionality and fastenability
Solution Approach 2:
The fastening function is segmented from the panel structure. The guide member is divided into distinct functional portions: a guide hole for mechanical part passage, a mounting portion for securing the panel, and a fastening portion for attachment to the lower cover. This segmentation allows each function to be optimized independently
2Length of stationary object
If a narrow bezel structure is used to achieve thin profile, then appearance and thinness are improved, but structural stability and fastenability worsen
Solution Approach 1:
The fastening function is moved from the horizontal bezel dimension to the vertical depth dimension. The guide member extends downward from the panel into the lower cover, providing secure attachment through the thickness of the assembly rather than relying on horizontal bezel strength
3Adaptability or versatility
If holes are provided in the display structure, then adaptability for mechanical parts is improved, but light leakage and rattle noise worsen
Solution Approach 1:
The guide member serves as an intermediary structure that manages the hole region. It provides a controlled opening for mechanical parts while the surrounding guide member structure blocks light leakage and prevents rattle noise by securing components in place
4Adaptability or versatility
If irregular shape is implemented in the display, then design flexibility and adaptability are improved, but manufacturing precision and assembly difficulty worsen
Solution Approach 1:
The guide member is designed as a universal component that can accommodate various irregular panel shapes. The mounting portion is configured to fit different panel perimeters, and the fastening portion provides standardized attachment to the lower cover, enabling precise assembly regardless of panel geometry
