LCD Case Connector Member Bottom Assembly Narrow Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display device case structures have a wide frame due to the length and thickness of fasteners, limiting the narrow frame requirement for stylish designs and large splicing applications, and the side assembly method complicates installation, reducing efficiency.
Innovation Solution
A case structure with a connector member that includes a fixing portion, connecting portion, and stopping portion, allowing the fastener to be installed from the bottom instead of the side, reducing the frame width and improving assembly efficiency by using overlapping side walls and interference-fitted holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If a conventional fastener structure is used with side assembly, then the fastening function is achieved, but the frame width becomes wider due to the length and thickness of the fastener
Solution Approach 1:
The patent inverts the conventional assembly direction by changing from side assembly to bottom assembly. The fastener is installed from the bottom of the back cover upward through the connector member, rather than from the side horizontally. This inversion allows the fastener to be positioned vertically within the overlapping region of the side walls, significantly reducing the horizontal frame width while maintaining the fastening function.
Solution Approach 2:
The patent transitions the assembly operation from a horizontal dimension (side assembly) to a vertical dimension (bottom assembly). By installing the fastener from the bottom upward along the vertical axis, the structure utilizes the vertical space within the overlapping side walls, thereby reducing the horizontal footprint and achieving a narrower frame width.
2Productivity
If side assembly method is used, then the fastening function is achieved, but the assembly efficiency is reduced due to difficult viewing and operation
Solution Approach 1:
The patent inverts the assembly approach from side installation to bottom installation. This inversion positions the assembly operation at the bottom of the device where factory workers can more easily view and operate, improving both assembly efficiency and ease of operation while achieving the same fastening function.
3Length of stationary object
If a connector member is added to enable bottom assembly, then the frame width is reduced, but the device complexity increases
Solution Approach 1:
The connector member serves multiple functions: it provides a mounting structure for the fastener, enables the bottom assembly approach, connects the back cover to the front frame, and maintains the structural integrity of the narrow frame design. By consolidating these functions into a single component, the overall structural complexity is minimized while achieving the desired narrow frame width.

AI summary
An LCD device and its case, the case includes a front frame and a back cover cooperating with each other and a fastener for assembling them together, and side walls of them are overlapped and holes are disposed in the side walls correspondingly. It further includes a connector member, the connector member includes a fixing portion closely fitted with a bottom wall of the back cover; a connecting portion closely fitted with the side wall of the front frame; a stopping portion inserted into the holes in the side walls of the front frame and the back cover correspondingly; an installation pole is disposed on the bottom wall of the back cover, the fixing portion of the connector member has an installation hole corresponding to the installation pole, the fastener goes through the installation hole and is fastened in the installation pole, and thus the connector member is fixed.
