Angled Snap Connector for LCD Frame Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display devices face inefficiencies in manufacturing due to deformation during reworking with snap connections and space constraints with screw-locking, especially in devices with narrow frames, which degrade manufacturing efficiency.
Innovation Solution
A connecting structure comprising a front frame, back plate, and a connector with snaps that form an included angle, allowing the front frame and back plate to be easily assembled without deformation, using flexible or elastic materials to engage with the frame corners, reducing the risk of deformation and accommodating narrow frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If snaps are used to connect the front frame and back plate, then the assembly process is simple, but deformation of the front frame occurs during reworking
Solution Approach 1:
The connector is divided into two separate sheet bodies (first sheet body and second sheet body) that form an included angle, with each sheet body having its own snap structure. This segmentation allows the connector to engage with different parts of the frame independently, distributing the connection force and preventing deformation during reworking while maintaining simple assembly.
2Strength
If screws are used for connection, then the connection strength is improved, but the manufacturing efficiency decreases due to additional riveting steps
Solution Approach 1:
The connector combines multiple connection functions into a single integrated component. The first snap and second snap work together to simultaneously engage with the front plate side frame and bottom plate, eliminating the need for separate riveting operations and maintaining high manufacturing efficiency while providing strong connection.
3Strength
If screw-locking is performed at the side frame, then the connection is achieved, but it interferes with the manufacturing efficiency in narrow frame structures
Solution Approach 1:
The connector utilizes a three-dimensional angular structure with sheet bodies forming an included angle, allowing engagement with the frame from multiple spatial dimensions. This dimensional approach enables effective connection in narrow frame structures without interfering with manufacturing processes, as the connector accommodates limited space through its angular geometry.
4Length of moving object
If the frame width is reduced, then the device becomes more compact, but there is no space left at the front for screw-locking
Solution Approach 1:
The connector's angular design with sheet bodies forming an included angle allows it to utilize vertical and lateral space rather than requiring horizontal space at the front of the frame. This dimensional adaptation enables the connector to function effectively in narrow frame structures where traditional front-mounted screw-locking would have no space.
